GETTING OUT WHAT YOU PUT IN: An Evaluation of Public Investment in Irish Sport Pete Lunn 51 INTRODUCTION The context for this year’s Budget differs sharply from most of those in the past decade and a half. The global economy has been buffeted by crises in financial markets. Oil prices, even after recent falls, are at very high levels. Furthermore, the sharp decline in housing activity in Ireland carries negative implications both for employment and for tax revenues. A consequence of the changed situation is that the date of the 2009 Budget has been brought forward by eight weeks. This year’s Budget Perspectives Conference, co-hosted by The Economic and Social Research Institute and the Foundation for Fiscal Studies, provides several inputs to inform macroeconomic decision making in these challenging times. In addition, two longer-term issues are addressed. The first of these deals with the policy framework for climate change, an issue that has risen rapidly on the Irish policy horizon in recent years. The second issue is the effectiveness of public spending in achieving its objectives in the area of sport, which is now recognised as an important contributor to health and quality of life in modern society. Developments in the global economy are of particular importance to Ireland, given the importance of trade in both goods and services to the Irish economy. In the first paper, Ray Barrell and Simon Kirby, of the National Institute of Economic and Social Research (NIESR) in London, provides an overview of the shocks which are besetting the global economy at present. After a long period of stability, the world economy is currently going through a period of financial turmoil, as banks face the consequences of poor lending decisions in a context of inadequate global regulation. At the same time, oil prices have risen to unprecedented levels. In a number of countries, and especially in Ireland, Spain, the United Kingdom and the United States, these factors are compounded by developments in the housing market. House prices that were buoyed by a credit boom in many countries over a number of years have now started to fall. The impacts on consumption and on housing investment are leading these economies into recession. Risk premia have risen in many markets, and investment is faltering as a consequence. Budget deficits have increased as a result of the unexpected slowdown in economic growth. While some of this is cyclical, trend growth has also been significantly reduced by factors such as the oil price rise and the increase in risk premia. While public policy can seek to smooth over the cyclical element, public spending plans will have to be reined back to remain in line with trend growth, if tax rates are not to rise significantly. International Situation 1 2 BUDGET PERSPECTIVES 2009 The implications of these global factors for the Irish economy, and of domestic factors such as the slowdown in housing activity, are dealt with in a presentation by Alan Barrett, Ide Kearney, Jean Goggin and Martin O’Brien based on the ESRI’s Autumn Quarterly Economic Commentary. As this is to be published on the day of the conference, details are not available at the time of writing. The Commentary and the presentation will give particular attention to the state of the public finances, and the appropriate stance for fiscal policy in 2009. Outlook for Ireland One issue that is of central importance in the Irish economy today is the appropriate size of the budget deficit for 2009. Four speakers will contribute to a roundtable on this issue: Ray Barrell (NIESR), Joe Durkan (UCD), Patrick Honohan (TCD) and Philip Lane (TCD). These papers and/or presentations will be available on the ESRI website. In their paper, Lisa Ryan (Comhar), Frank Convery (UCD) and Noel Casserly (Comhar) point out that Irish policy on climate change is substantially shaped at EU level, with national targets and some key mechanisms coming to us from the European Union. For example, the EU Emissions Trading Scheme (ETS) has created scarcity in the market place for the power and heavy industry sectors, and they face a price signal per tonne of CO2 ‘allowance’ that tells them that reduction at a cost per tonne below the market price will be profitable, and that increased emissions will incur a heavy cost penalty. Ryan, Convery and Casserly argue that auctioning of allowances – not present in the current system, but included in proposals to revise the system post-2012 – would represent an improvement in the efficiency of the policy. Climate Change There is, however, some freedom of action open to Ireland in responding to new and demanding targets (to be achieved by 2020) proposed by the EU for sectors not covered by the ETS (agriculture, transport, waste, heat and process related emissions from residential, commerce and industry not in the trading scheme). Ryan, Convery and Casserly argue that a central element of policy in this area should be the introduction of a carbon levy to reach the level of the allowance price in the EU ETS They also suggest that if costs of reducing carbon emissions are substantially higher in the non-ETS sector, efficiency in achieving the overall target would require some flexibility between the ETS and the non- ETS sectors; this would require a decision at European Commission level. Achieving value for money in public expenditure is another key issue, whatever the state of the economic cycle. Its importance is even more marked in the present situation. In order to attain this, we must have a clear idea of the objectives of particular expenditure programmes, and of the extent to which the expenditures contribute to these objectives. This is the approach taken by Pete Lunn (ESRI) in assessing the economic returns to public investment in sport, which have increased very substantially over the past decade. The stated aims of Irish sports policy emphasise improvements in health and quality of life. There is, indeed, considerable empirical support for the view that there are significant health and social benefits to be had from participation in sport. However, the Sports Expenditure: Hitting the Target? INTRODUCTION 3 analysis challenges the way current policy addresses three trade-offs in the allocation of resources: the balance between “elite” and “grassroots” sport; the trade-off between investment in sporting facilities (physical capital) and participation programmes (human and social capital); and the allocation of public money across the range of different sporting activities. In each case, the evidence base suggests that the aims of policy could be better served by a reallocation of sports investment which takes recent research findings on sports participation into account. THE BUDGETARY IMPLICATIONS OF GLOBAL SHOCKS TO CYCLES AND TRENDS IN OUTPUT: Impacts of Housing, Financial and Oil Shocks Ray Barrell and Simon Kirby* After nearly two decades of stability the world economy is going through a period of financial turmoil as banks face the consequences of poor lending decisions. House prices were buoyed by a credit boom in many countries, but they have started to fall. The impacts on consumption and on housing investment are leading many economies into recession. Risk premia have risen in many markets, and investment is faltering as a consequence. At the same time oil prices have risen to unprecedented levels. Budget deficits have increased as a result of the unexpected slowdown in economic growth. Some of this is cyclical, and can be ignored. However, the rise in risk premia and the oil price have together reduced trend growth by half to one percentage point for four to six years in many countries. Public spending plans will have to be reined back to remain in line with trend incomes, or tax rates will have to rise. Not all of the recent increases in budget deficits can be ignored, and they will have to be addressed once the dust has settled. Abstract The OECD economies are facing three severe negative shocks to growth. Housing markets have been badly affected by the ending of their booms and house prices and housing investment are falling in a number of countries. Housing market problems have severe cyclical effects, but it is not clear they have a sustained impact on output. Of the two remaining shocks, one is emanating directly from financial markets whilst the other is in the form of 1.

These shocks are likely to have an impact over a longer period of time, and they will have an impact on the sustainable level of output as well as on the cyclical component in economic activity around sustainable, or equilibrium, output. When the rate of growth of an economy slows, tax receipts will be reduced and expenditure on social support programmes will increase. These automatic stabilisers are built in to the fiscal frameworks in use in Europe, and should help to offset the negative impacts of the shocks on output growth. Output falling below capacity is reasonably associated with increased budget deficits, and the faster the rate of increase in the output gap the greater the budgetary allowance that can be taken under the Stability and Growth Pact. Medium-term expenditure planning is best isolated from changes in the cyclical position of the economy. If shocks also reduce trend output growth then medium-term expenditure plans should change. Hence, it is important to be able to distinguish between the cyclical and structural elements in the effects of a set of shocks when looking at the budgetary response. We discuss the evolution of recent financial market turmoil and its effects on house prices. We evaluate the impacts of falling house prices on the economy and discuss the impact of recent declines in housing investment. We also look at the impact of increased credit spreads on the economy with an emphasis on their long term effects. We also discuss the impacts of the recent increase in oil prices. We conclude by arguing that the housing market crisis is cyclical and its impacts on the fiscal position can largely be ignored. However, increased risk premia and higher real oil prices impact on the longer-term prospects, and in most countries they require an adjustment to spending plans or an increase in tax rates. House prices have been rising in almost all European countries (with the notable exception of Germany) and they have also risen in North America, as Barrell and Kirby (2008) discuss. Housing bubbles have been common in the UK, and were also major factors behind the Nordic banking crises of the early 1990s. House price bubbles are commonly associated with financial liberalisation and innovation and with subsequent financial crises. The recent bubble probably stemmed from increased lending given income levels and from low real interest rates on that lending. Large volumes of saving, especially from China and the rest of East Asia, were holding down real interest rates. Partly as a consequence of these low real rates we have seen a wave of financial innovation. Low real rates squeeze the rents banks get on their zero interest deposits and hence put pressure on them to innovate in order to maintain their profit margins. Developments in our understanding of risk, in combination with the pressure to innovate, have led to the production of new styles of assets that share and spread risk. Bundling mortgages into securities spreads risk, and this raises the welfare of society and increase the capacity to borrow. 2. The Genesis of the Financial Crisis and Housing Bubble However, the innovations in types of assets did little to reduce the underlying level of risk. This may not have been apparent, and risk probably became under priced. The under pricing of risk became clear as default rates on various US issued sub prime assets began to rise, putting pressure on the balance sheets of the banking sector. The international nature of banking markets meant that many of the risky assets had been bought by European 6 BUDGET PERSPECTIVES 2009 banks, and losses have been larger than initially anticipated. This was perhaps because US banks had a better understanding of lax US bankruptcy and housing loan laws and they were hence, willing to pay less for these new assets than the less well informed Europeans. As soon as loans began to become more expensive, with lower loan to value ratios, in order to take account of higher perceived risk, house prices began to weaken. Housing investment had begun to fall in the US in the first quarter of 2006, but as credit constraints tightened in mid-2007 its decline was accelerated. Uncertainty over the location of the bad debts meant that banks were unwilling to trust each other, and interbank transactions dropped and the spread on wholesale borrowing has risen. This has further tightened credit conditions and has contributed to the cyclical slowdown of many economies. Figure 1: Housing Wealth as a Proportion of Disposable Income 0.00 1.00 2.00 3.00 4.00 5.00 6.00 France Germany Ireland Spain UK US 1995 2006 Rising real house price can mean that the value of the owner occupied housing stock might rise relative to incomes (Figure 1). It can also rise if there is a great deal of housing investment, as in Ireland, where investment in housing was around 12 per cent of GDP (Table 1). If housing wealth falls then consumption may be affected, and hence the economy may slow down. There is reasonably clear evidence that housing wealth affects consumption in many countries, as Barrell and Davis (2007) show. Although a change in housing wealth driven by a change in house prices may not be national wealth, if individuals are myopic and do not value the inheritance they leave their children as much as their children would value it then housing wealth might be perceived as individual wealth.1 In the long run individuals appear to react no more to their housing than their financial wealth. However, there is clear evidence that there is significantly more signal in a rise in housing wealth driven by asset prices than in a rise in financial wealth driven by the same factors. It is possible to use the National Institute Global Econometric Model, NiGEM to evaluate the impacts of a fall in house prices, and Figure 2 reports on the effects of a 10 per cent concerted fall. In each of these countries there is strong evidence that consumption depends on housing wealth, As Barrell and Kirby (2008) show, the impacts on consumption of a fall in housing wealth are between two and three times larger than the 1 This is the same argument as made over whether government bonds are net wealth. THE BUDGETARY IMPLICATIONS OF GLOBAL SHOCKS TO CYCLES AND TRENDS IN OUTPUT 7 impact on GDP. This is largely because a high proportion of any fall in consumption is absorbed into imports, with the offset being larger in more open smaller economies. Underlying these simulations are the assumptions that the monetary authorities adjust interest rates in line with changes in demand, and that forward looking foreign exchange markets cause the exchange rate to jump down initially, offsetting some of the effects. Equity markets are also forward looking and react to the fall in interest rates that results from the fall in house prices. Consequently, equity market wealth initially jumps up to partly offset the fall in housing wealth. However, the offset is not large, and if the authorities did not react there would be no offset. Figure 2: Effects of a 10 Per Cent fall in House Prices on Real GDP -1.20 -1.00 -0.80 -0.60 -0.40 -0.20 0.00 France Germany Ireland Spain UK USA Pe rc en t d iff er en ce fr om b as el in e (le ve l) year 1 year 2 year 3 The crisis in housing markets has also led to a fall in housing investment, as we can see from Table 1. Housing investment has fallen most sharply in the US and in Ireland. UK housing investment has dropped by a more modest amount. Simulations on NiGEM suggest that the fall in investment has probably reduced US GDP growth by just over ½ percentage point. The effects on the UK are less, mainly because the share of housing investment is smaller and the decline in investment has been lower. Housing market downturns cause sharp and temporary declines in output, and they are clearly cyclical shocks. They can at minimum be ignored when policy makers set longer term budgetary plans, since the widening of deficits is short term and cyclical. The effects of a widening output gap on budget deficits depends on the underlying cause. Barrell, Hurst and Mitchell (2007) show that consumption led slowdowns have a significantly greater impact on deficits than those led by slower export growth. On average an expansion of the output gap by 5 percentage points might worsen the budget by 2½ per cent of GDP or so, but if the downturn is from tax rich consumption it could be as high as 3½ per cent of GDP. Since these are cyclical such budgetary changes do not need intervention to correct them.

In addition, the wealth effect from high and rising house prices has been a major factor behind low levels of savings in countries such as the UK and the US, and a rise in the savings ratio that will result from lower housing wealth is also to be welcomed in these two low saving countries. If politicians requiring re-election feel a need to react, or if they think they should stabilise the economy by taking action, then programmes to offset the employment effects of lower housing investment would make more sense than policies designed to stop house prices adjusting back to their equilibrium level. Financial crises are episodic and frequent, and are difficult to avoid without major impacts on the prospects for financial innovation and economic growth. Financial innovation can reduce borrowing costs which lowers the user cost of capital, and hence for a period at least it can be important for raising growth. However, it is difficult to distinguish between sustainable innovation and excessive risk taking. Regulators have to ensure they encourage the former and discourage the latter. Financial sector regulation is extremely difficult, and financial innovation often finds ways round regulation. However, good regulation frequently revised to keep up with markets is essential if financial markets are to be constrained from generating a depression of the scale seen between 1929 and 1933. 3.

Source: Barrell and Hurst (2008). Table 2 gives some details of four recent crises in major economies. The Nordic crises were sharp and had a significant effect on output, but they were associated with rapid and poorly designed financial deregulation that led to excessive consumer borrowing and housing market bubbles. The collapse of consumption spending that came with the pricking of asset bubbles was a factor behind large scale losses in the banking sectors, as were exposed positions in foreign exchange dealings. Real house prices fell 30 per cent in Finland between 1991 and 1993, whilst they fell by 25 per cent in Sweden over the same period. In both countries the whole banking system had to be nationalised. Output losses, commonly calculated as the cumulate drop below trend growth, were large, but there seems to have been little effects on longer-term growth prospects. The Japanese crisis also followed from ill judged deregulation and an expansion of borrowing but involved fewer failures but the crisis lasted for a significantly longer period. It was driven as much by falling commercial property prices after an extreme bubble as by personal sector problems, and it led to a re-evaluation of risk premia in Japan, raising the user cost of capital and reducing trend output growth for some time. The crisis probably has had a permanent effect on the sustainable level of output in that economy.

There has been a housing market element, as we have discussed above, but excessive lending and an under- estimate of default risk, especially within the US, led to low risk premia for all borrowers. As Figure 3 shows, the spread between risk free government borrowing and corporate borrowing costs has risen in the US and Europe, as have equity premia and consumer borrowing costs. This looks like a medium to long term re-evaluation of risk, and it will raise the user cost of capital, and reduce the equilibrium level of the capital stock and hence sustainable output.

Interest rate rules in place, forward looking financial and labour markets. Barrell and Hurst (2008) discuss the impacts of a rise of spreads of this scale on output, but look only at the effects of a temporary change. It looks increasingly as if the crisis in financial markets will have a long-term impact on risk premia, as in Japan in the 1990s. Hence, we have repeated the simulations, but have extended them into the medium term to investigate the impacts on sustainable output. In this scenario risk premia were raised by 2 percentage points over the medium to long term in Europe and North 10 BUDGET PERSPECTIVES 2009 America.2 As a result of this both investment and consumption would fall. The user cost of capital would have risen by less than 2 percentage points as long-term risk free real interest rates would fall in response to lower investment and higher saving. As we can see from Table 3 sustainable output would fall by more than one per cent in the Euro Area and by less in the US, reflecting higher capital output ratios in the former area. Permanent changes in output require permanent changes in government spending, and these are implemented in the model, so deficits do not rise. Between the end of 2006 and September 2008 oil prices rose from around $50 per barrel to a currently projected level of $113 in 2009. Oil prices reached a peak of $144 a barrel in July before falling back over the summer. These recent oil price increases have taken the real oil price back to, or above the levels seen in the 1980s, as we can see from Figure 4 which plots the exchange rate adjusted real oil price for the UK, the US and the Euro Area. The recent strength of the euro has meant that the full impact of the rise in the dollar oil price has been partly offset by the exchange rate, but even there oil prices are likely to remain high. However, high real oil prices may be less significant than they were in the 1970s, largely because oil (or rather fossil fuel) use has fallen as a percentage of output, as can be seen from Table 4.3 4. Oil and the Economy Figure 4: Real Oil Prices in Domestic Currencies 2000 = 1.0 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 19 70 Q4 19 73 Q3 19 76 Q2 19 79 Q1 19 81 Q4 19 84 Q3 19 87 Q2 19 90 Q1 19 92 Q4 19 95 Q3 19 98 Q2 20 01 Q1 20 03 Q4 20 06 Q3 20 09 Q2 US UK Euro Area Fossil fuel use is more important in the US than in Europe, and its share of nominal costs has risen from 3 per cent in 1995 to a projected 12 per cent in 2008. If prices were just a mark up over costs, and if there were no second round effects, and no monetary policy response, then the $53 dollar rise in oil prices between the end of 2006 and September 2008 would suggest that the overall price level should rise by 4 per cent in the USA, by 2 2 The same policy and expectations assumptions were used as in the previous scenario. 3 These calculations assume that coal and gas prices are free to move in line with oil prices, but until the 1980s they clearly were not in many countries, and actual expenditure may have been lower as a per cent of GDP. THE BUDGETARY IMPLICATIONS OF GLOBAL SHOCKS TO CYCLES AND TRENDS IN OUTPUT 11 per cent in the UK, and somewhere between the two in the Euro Area and Japan. Second round effects on prices could increase the impact of the increase in oil prices if nominal wage growth rose markedly because real wages were not adjusting quickly to their new, lower, equilibrium trajectory.

Increases in oil prices change the terms of trade between oil producers and oil consumers, and also affect the productive capacity of the economy to produce output as fewer non-labour inputs are likely to be used. In countries that do not produce fossil fuels this change in the terms of trade is reflected in the balance of payments, and both real wages and real incomes must adjust. If they do not then unemployment will rise noticeably, as it did after the oil price shocks of the 1970s. In the Euro Area the rise in the price of oil between 2006 and 2008 means that the terms of trade have changed by 1.8 per cent (the rise in the nominal share of fossil fuels over that period) and real wages and real incomes must grow less rapidly than they otherwise would. For instance real wage growth would have to be ½ a percentage point lower for four years than had been anticipated in 2006 in order to accommodate the oil price increase. The change in the terms of trade is much more important in the US, where real wages would have to grow one percentage point less rapidly than had been anticipated in 2006. The US is a significant fossil fuel producer, and real income growth would not have to slow down so much, but real incomes would still have to be around three percentage points lower than they would otherwise have been in four years time. The UK remains almost self sufficient in fossil fuels, and real incomes would fall only marginally. However, real (producer price adjusted) wage growth would still have to fall by around half a percentage point a year for four years. The rate of growth of incomes of pensioners and other who are dependent on oil rents (including the average tax payer) would not decline anywhere near as much. If oil prices had stayed at their April 2008 levels then output growth would have been stronger, and the rate of inflation lower. The exact magnitudes depend upon the policy reactions of the monetary authorities and on how wage bargainers respond. In the 1970s neither policy makers nor wage bargainers seemed to take account of the need for lower real wage growth, and as a result the rate of inflation rose markedly as bargains attempted to keep real wage growth on track and the monetary authorities tried to keep real interest rates constant. 12 BUDGET PERSPECTIVES 2009 If oil prices had not peaked in July 2008 and were $33 dollars lower now then inflation pressures would have been less. Figure 5 reports the impacts of such a change on inflation and output. The counterfactual implies that higher oil prices have raised inflation and reduced output. We assume policy makers would have cut interest rates, and that wage bargains would take account of the changed real prospects Rational expectations drive labour and financial markets, and agents know the real equilibrium and what the reactions of the authorities will be. The cyclical reactions of the economy will depend on how much the authorities change interest rates and how much labour bargains adjust to changes. The effects on output and prices depend on the oil intensity of production, with the largest effects being seen in the US. The US has the most flexible labour and product markets in this group, and hence prices rise more rapidly. Lower levels of demand will reduce budgets, with one per cent lower output being associated with a larger deficit of 0.5 to 0.7 per cent of GDP. It is important to know how much of this effect is permanent.

Weale (2008) suggests that the long-run elasticity of demand for fossil fuels has to be around minus one. It is clear, however, that adjustment is slow. We estimate it can take 4 years for 66 per cent of any adjustment to take place. If oil prices had not risen from their 2006 levels then more oil would be used as an input into production, and more goods could be produced. We have calculated the change in fossil fuel use that would take place between 2006 and 2010 in the light of these assumptions and used it in a growth accounting exercise. We first assume that oil usage drops in line with price increases, and calculate a trajectory for output. We then assume prices and shares do not change, and hence usage remains at 2006 levels. Figure 6 plots the impacts of these changes on the projected level of equilibrium output in 2010. The impacts are highest in the oil intensive USA and lowest in nuclear intensive France. In the very long run we would expect equilibrium output to be up to 2 per cent lower in the E Oil Price Impacts on Equilibrium Output (Effect Our results on the short, medium and long-term impacts of higher oil prices suggest that much of the impact, even in the short term, must be seen as structural and not cyclical. If sustainable output is likely to be 2 per cent lower than it would otherwise have been, then optimally organised government spending also needs to be 2 per cent lower than currently, otherwise government budgets would deteriorate. Ignoring the impacts of oil prices on trend output is as serious as ignoring its effects on real wages. If spending plans do not adjust then taxes will have to rise, and this will put downward pressure on real consumption wages. If bargainers resist the effects of oil price increases they will also resist the impacts of increased taxes, and for a perio 14 BUDGET PERSPECTIVES 2009 0.0% 0.5% 1.0% 1.5% 2.0% 2.5% 3.0% 3.5% 4.0% 4.5% 19 86 19 88 19 90 19 92 19 94 19 96 19 98 20 00 20 02 20 04 20 06 20 08 Value Volume Figure 7: Fossil Fuel Use in Irish GDP he impacts ending would be the same made taxes will have to rise to keep the public fiancés on a sustainable path. It is possible to make a simple estimate of the impact of higher oil prices on Irish output, although growth accounting is made difficult both by the absence of an easily available and long series for output at basic prices. This problem is exacerbated by the discrepancy of perhaps 14 per cent between national output and national income that comes from the prevalence of profit shifting through the Irish accounts. Given these problems we should treat Figure 7 with care, as it probably understates the role of energy in the Irish economy. As in earlier exercises, we take oil, coal and gas usage and value it at world market prices and compare to money GDP. This gives an energy intensity of output that is similar to the UK. In the longer term the rise in the oil price between 2006 and 2008 will require trend output in Ireland to be around 2 per cent or so lower, and hence that trend output grows by up to half a percentage point less a year for four years. T on optimally organised government sp Recent shocks to financial, housing and oil markets have caused growth to slow markedly in a number of economies. The shocks related to the housing market are probably cyclical in their effects, and their impacts on budget deficits can be treated with neglect. However, over the last two years there appears to have been a sea change in both the real oil price and in risk premia applied to investment. Between them these structural shocks have reduced sustainable output growth by between ½ and 1 per cent a year, depending on the economy considered. By 2010 sustainable output in the European economies is likely to be 2 to 3 per cent lower than had been projected in 2006, whilst the effect on the US would be around 4 per cent. Real wage growth has to slow to accommodate this. In addition, government spending plans have to be adjusted or taxes will have to rise. If the government’s share of output is to remain constant then spending plans must be revised down, with spending growing ½ to 1 per cent slower in real terms than projected in 2006.

Our national targets and mechanisms have come to us from the European Union. The European Union Emissions Trading Scheme (EU ETS) has created scarcity in the market place for the power and heavy industry sectors, and they face a price signal per tonne of CO2 (‘allowance’) that tells them that reduction at a cost per tonne below the market price will be profitable, and increased emissions will cost. The response as to how to deal with this situation is left entirely up to the firms involved. This flexibility is crucially important to support innovation and competitiveness. The European Commission’s proposals for EU ETS post 2012 include auctioning of allowances – in particular in regard to the power sector – and centralisation of cap- setting. We support these proposals. Abstract Very demanding targets are now proposed by the Commission for the non-trading sector (agriculture, transport, waste, heat and process related emissions from residential, commerce and industry not in the trading scheme), to be achieved by 2020. This EU- originating target should supersede the national target set in the Programme for Government of an 86 per cent reduction from 2007 by 2010. We propose that the same flexibility and support for innovation that exists for the trading sectors apply also to the non-trading sectors, achieved by the immediate introduction of a carbon levy to reach the level of the allowance price in the EU ETS, with the revenues used to: reduce other taxes (40 per cent), address fuel poverty (30 per cent) and further support reduction in greenhouse gas emissions (30 per cent). The latter should be focused on the least cost opportunities and research and development. The levy on transport might later be replaced by an individualised cap and trade scheme. If the costs of abatement at the margin are substantially higher in the non-trading sector, then some flexibility between the trading and non-trading sectors should be sought from the European Commission. Time is not on our side, so action in Budget 2009 is important. 16 MOBILISING MARKET-BASED INSTRUMENTS FOR CLIMATE CHANGE IN IRELAND 17 The excessive emission of greenhouse gases is a manifestation of market failure which arises as a result of the public good nature of greenhouse gas emissions. In a well-functioning market resources are allocated efficiently1 but well-defined property rights are necessary for this to occur, which is generally not the case with public goods such as greenhouse gas emissions. 1. Introduction The essence of markets is that they clear – a price emerges that brings demand and supply into equilibrium. If demand increases and supply does not, then the market price rises to bring them into equilibrium. If supply increases and demand does not, then the price falls. The market fails when a price does not emerge that reflects relative scarcity. This is typically the case with environmental endowments. They are often not ‘owned’ and as use intensifies, no price signal emerges to alert consumers to use them more parsimoniously, or bring use into balance with assimilative capacity. In regard to climate change, we emit gases into the atmosphere that warm the globe, and we do not get a price signal telling us that the capacity to assimilate these gases without the risk of substantive adverse effect is limited and is being overused. This paper is about ways in which we correct for market failure by creating a price that signals scarcity, and what the implications are for fiscal and budgetary policy. Specifically, we address two choices: limiting quantity of emissions, and allowing trading amongst emitters, thereby producing a price, or introducing the price directly in the form of a tax per unit of pollution emitted. Although historically the most common instrument implemented in the area of environmental policy has been command and control policies, these have been found to frequently be inefficient. Standard regulation can be statically inefficient in that it may not achieve environmental objectives at minimum cost, and it may be dynamically inefficient, since there may be no incentive for polluters to continually improve. In latter years demand-side market-based instruments such as taxes, green subsidies, and emissions trading have become more popular, as they provide an incentive to continually improve environmental performance at least cost. The revenue generated by market-based instruments can provide a double dividend if they are used to reduce other taxes which may be slowing economic growth2 or creating inequity in society. 2. Market- based Policy Instruments for Greenhouse Gas Mitigation There are several features that distinguish greenhouse gas emissions from other problems. First, the pollutants act globally and, therefore, a successful abatement strategy requires a large majority of emitting countries to cooperate and abate, which complicates the political implementation of policy measures. Additionally, CO2 emissions3 are mainly a direct result of 1We may define efficiency in terms of Pareto optimality, which is the situation where we are unable to reallocate resources without making at least one person worse off. 2An example is the eco tax in Germany where a tax was levied on fossil fuels and the revenue was used to reduce labour taxes. 3There are six groups of greenhouse gases listed under the United Nations Framework Convention for Climate Change and CO2 emissions are estimated to be responsible for 60 per cent of the ‘greenhouse effect’ (www.UNFCCC.org). 18 BUDGET PERSPECTIVES 2009 the combustion of fossil fuels and, therefore, are essentially a by-product of the industrial world. Abatement is different to that of other pollutants since end-of-pipe abatement of greenhouse gas emissions is expensive and, therefore, modifications to the combustion process are usually necessary, such as improvement in energy efficiency or fuel switching. However, this kind of abatement can provide side benefits, since more efficient combustion also saves the operator energy or fuel costs, and may also reduce other pollutants. A third feature of greenhouse gas emissions is that the consequences of abatement or lack of it will not be felt in the present but in the future. In an ideal world the optimal emissions abatement level can be estimated by comparing the marginal cost and marginal benefit of the best available abatement technology. However, there is generally great uncertainty with respect to the shape and position of the marginal benefit and marginal abatement cost curves. Often the abatement costs are not known to the policymaker, due to incomplete information on abatement technologies. In many cases also the technology has not been fully developed and, therefore, the future costs of abatement may not yet be known even to the manufacturer. The marginal cost of abatement curve may be neither smooth nor linear, since abatement technologies may be much more costly for increasing abatement levels. Furthermore, as private agents are not faced with the full social costs of greenhouse gas emissions, the private damage costs usually do not equal the social damage costs. It may be very difficult to estimate the damage costs, both social and private, since the cost function in the real world is most likely non-linear and dependent on the number of ‘victims’, time, pollutant composition and perhaps location (Sterner, 2003). An important consideration in the estimation of greenhouse gas emissions costs is uncertainty regarding the future concentration of greenhouse gases in the atmosphere as a result of current emissions, and the implications. The intertemporal dimension adds complexity to the issue since it is not certain what the impact of any given greenhouse gas concentration will have on future global and regional climates. Weitzman4 poses the intellectual and empirical challenge when catastrophe is a possibility: Societies and ecosystems whose mean ambient temperature has changed in the geologically instantaneous time of two centuries or so by 11c-20c are located in terra incognita, since such high average temperatures have not existed for hundreds of millions of years and such a rate of global temperature change might be unprecedented even on a time scale of billions of years. Standard conventional Cost Benefit Analyses (CBAs) of climate change do not come even remotely close to grappling seriously with this kind of potential for disasters. When comprehensive CBA includes plausible, if unknown, probabilities of (and plausible, if unknown, damages from) catastrophic climate change, the policy implications can be radically different from the conventional advice coming out of a standard economic analysis that essentially ignores this kind of potential for disasters. 4Weitzman, Martin, 2008. “On Modelling and Interpreting the Economics of Catastrophic Climate Change”, Harvard University May 2008. See: http://www.economics. harvard.edu/faculty/weitzman/files/REStatModeling.pdf MOBILISING MARKET-BASED INSTRUMENTS FOR CLIMATE CHANGE IN IRELAND 19 Standard environmental economics textbooks tell us that the optimal level of greenhouse gas emissions abatement is at the point where the marginal abatement cost is equal to the marginal damage cost. In the case of optimal regulation, the pollution standards could be set to the optimal level. Similarly, if a policy instrument of taxes or charges were preferred, the charge would be set at optimal t*5 to produce the optimal abatement level or if a system of permits were implemented the quantity of permits issued would be equal to the same emissions level. So, theoretically at least, under ideal conditions the optimal abatement level can be achieved with either a tax or permit-based system. In the real world, conditions are rarely ideal and policymakers must settle for a second or even third best policy solution. This is because, even if it were possible to estimate the optimal abatement level, there are often political constraints related to the implementation of the first best policy selected using the criteria above. Particular conditions, for example the socio-economic situation, information availability and structure, technology availability, environmental problem at hand, and political system demand different policy instruments. Our perspective takes as given the European Union policy framework in which we find ourselves in Ireland in 2008. This is far from what many economists would regard as optimal if we could design and implement policy from a tabula rasa. Going back to Weitzman (1974), there is a literature which makes the case for the use of environmental taxes rather than emissions trading as a means of addressing climate change. There is also a very convincing case that, on grounds of both economic efficiency and environmental effectiveness, if emissions trading is to be used, it should apply to all emissions. Our reality is that there is no EU-wide greenhouse gas tax and little prospect of same, and the emissions trading scheme is only partial in coverage. Given this context, the next sections describe the market-based policy options available for Ireland and outline their potential to efficiently and effectively reduce greenhouse gas emissions while improving competitiveness and social equity. The first of these approaches is called ‘emissions trading’ to which we now turn. In Annex A, we discuss what emissions trading is, the context and pressures which produced a European Union Emissions Trading Scheme (EU ETS) for carbon dioxide, the main greenhouse gas, how it has been implemented and how it has operated in terms of price effects, abatement, creation of markets etc. Readers who are not familiar with trading in general, and the European scheme in particular, should read this annex before proceeding. 3. Emissions Trading in Ireland The questions that are interesting to address in regard to Ireland’s performance and potential vis-à-vis EU ETS include the following: 5When the charge or tax is set at the intersection of the marginal abatement cost and marginal damage cost the tax is referred to as a Pigouvian tax. 20 BUDGET PERSPECTIVES 2009 How well did Irish companies adapt to the market over the 3 year pilot phase in terms of transactions, and in accessing allowances from a variety of sources? Are utilities in Ireland capturing surpluses in the form of price increases that reflect the cost of allowances, but getting the allowances mostly for free? If so, should there be an attempt to use the tax system to capture some or all of such surpluses? Are there changes proposed for the system that Ireland should support or oppose? Is there evidence for, or a prospect of, competitiveness issues, nationally or sectorally? If a carbon tax is introduced, should it apply to those in the trading scheme? Taking each of these in turn: Trading Performance of Irish Companies in the European Union Emissions Trading Scheme (EU ETS) during the First (Pilot) Phase, 2005- 2007. The net balance in volume and cash terms is shown in Table 1 below: Table 1: Net Balance in Allowances over the First (Pilot) Phase, EU ETS, Ireland Year Average Price Per Tonne € Net Volume Net Value 000 Tonnes 000 € 2005 20.6 406 -8,373 2006 16.6 -229 3,797 2007 0.6 733 -440 Total 5.5 911 -5,016 Source: Community Independent Transactions Log (CITL). For the whole period, Ireland had a net expenditure of just over €5 million and net purchases of 911,000 tonnes, at average cost per tonne of €5.50. There were net sales in 2006, when prices were relatively high, and the largest net purchases took place in 2007 when prices were at their lowest. In EU ETS, installations receive their annual allocations in February, but do not have to balance their account for the previous year until April, which means they can de facto borrow allowances, and many seem to have borrowed forward to avail of the much cheaper allowances in 2007. We can conclude that, overall, companies were either lucky or good, or perhaps both, at reducing the costs of meeting their commitments. As regards selling allowances, this happened in the context of an overall short situation. MOBILISING MARKET-BASED INSTRUMENTS FOR CLIMATE CHANGE IN IRELAND 21 ELECTRICITY PRICE PASS THROUGH For the pilot phase, the Commission on Energy Regulation (CER) only allowed the marginal cost – the cost of the net purchases of allowances – to be passed on to consumers. However, the situation changed in regard to the second phase (2008-2012) and thereafter. This is in the context that, overall, utilities were left short in the sense that allocations were lower than historic emissions in this second phase. A good sense of the key issues and challenges for the future can be discerned by examining the Environmental Protection Agency (EPA) publication, Ireland’s National Allocation Plan Second Consultation, October 2 2007,6 which applies to the 2008-2012 period. The total quantity of allowances to be allocated in the period represents 87 per cent of forecasted emissions in that period. Of the total 9 per cent has been ‘held back’ to cover new entrants. This provision in the EU scheme is controversial, as it is held by some to de facto discriminate in favour of polluting incumbents, on the following basis: a new entrant who proposes to build an emission-free plant will get no allowances, while an incumbent who wishes to develop a new plant with emissions can use the asset value of their existing free allowances to get cheap credit for the expansion, and get the additional emissions ‘covered’ by receipt of more free allowances. A total of 22.262 million allowances annually are allocated. This compares with 22.32 million annually allocated in the first period, a reduction of less than one per cent. Holders are capped as regards the extent to which each installation can meet their needs using linking mechanisms to 12, 11, and 1 per cent respectively in the power generation, cement and general sectors. Only 0.5 per cent of allowances will be sold, “to defray the expenses of administering the emissions trading scheme”. There are over 100 installations included, and we can divide them into power generation, cement, and the rest. The bulk of allowances go to electricity generating stations and cement plants. (See Annex Table 1 for top 17 installations, ranking based on proposed allocation for 2008-2012.) All 12 electricity installations have been allocated 68 per cent of their ‘relevant emissions’, the latter comprising mainly their historic emissions (with 2003 as the key year in this regard), or their projected emissions. It is assumed that the contribution of renewables grows from 4.3 per cent in 2003 to 15 per cent in 2020 and 33 per cent by 2030, and this expectation was accounted for in making allocations to the powergen sector. The companies involved will need to bridge whatever gap exists between their free allocation and their prospective emissions by a combination of abatement, fuel switching, purchase of allowances, and purchase of project-based credits from Joint Implementation (developed countries) or Clean Development Mechanism (CDM). 6http://www.epa.ie/downloads/pubs/air/etu/name,23524,en.html 22 BUDGET PERSPECTIVES 2009 With the emergence of the all-island electricity market, it is clear that generators in this new market will be expected, as a condition of their generation licences, to bid into the all-island wholesale market at prices that fully factor in their short-run marginal costs (SRMC) for each half-hourly dispatch period. Such costs explicitly include the full opportunity cost7 of EUAs for each half-hour period,8 a provision which did not apply during the pilot (2005-07) phase. It is likely that any ‘must run’ status peat-fired stations would be allowed to include any Public Service Obligation (PSO) subvention as a negative marginal cost. However, the overall bidding principle of SRMC is quite clear. Under this system, electricity consumers will pay at least some of the opportunity- cost value of allowances, even where the utilities have not had to pay for them. It is important from an environmental performance point of view that households will face and experience the costs of emitting CO2 into the atmosphere associated with their consumption of electricity. It is also appropriate that the charge will vary depending on the carbon intensity of electricity generation. Under a system where permits are issued without cost to the electricity companies, it was the pass through of the opportunity cost of free allowances in the pilot phase that encouraged Germany, the UK and Italy to auction a significant proportion of their allowances (up to 10 per cent is allowed under EU ETS regulation). But Ireland is only selling 0.5 per cent of its allocation, so there is not a direct substantial flow to the Exchequer. Where does the public interest lie in regard to the pass through? Pass through encourages reduction in electricity consumption, and should be allowed; it confronts the consumer with the marginal costs of abatement. But should the government claw back some or all of this pass through to the extent that it occurs as ‘unearned’ profit by the company? In considering this issue, it is useful to distinguish between the State- owned Electricity Supply Board (ESB) and the rest. The ESB is the dominant incumbent, with a proposed allocation over the five year phase 2 (2008-12) period of 38.5 million tonnes of CO2, which is just over two and a half times the allocation to the rest of the utility sector. ESB The value of the pass through to the ESB is estimated for two scenarios – assuming a price of €23 per tonne and pass through of 50 per cent and average price of €25 – and pass through of 70 per cent – is shown in Table 2. The total value for the five year second phase is €438-668 million range. 7‘Opportunity cost’ is the value foregone in using an asset and is independent of whether one paid for it or not. Thus, an allowance in EU ETS for delivery in 2008 is today trading at €26.00 per tonne of CO2. If – as will be the case in Ireland – emitters get these valuable allowances for free, they will still recognise their full value as they make decisions. Just because an indulgent aunt gives you a house for free, you do not give it away or rent it for free – you recognise its full opportunity cost. 8See: All Island Project – the Bidding Code of Practice – A Response and Decision Paper AIP-SEM 07-430, 30 July 2007.

However, the policy context is rapidly evolving. In July 2008, the Commission on Energy Regulation (CER) welcomed the joint announcement by the Spanish utility Endesa and the ESB that the former was purchasing a number of ESB power generation stations as part of the Commission’s CER-ESB Asset Strategy Agreement aimed at reducing ESB’s share of the power generation market to 40 per cent by 2010. On March 27, 2008, the ESB and the government announced a major investment programme, whereby between now and 2020, €22 billion will be invested, including networks (€11 billion) that will facilitate the development of 6,000 MW of wind power island wide development on its own account of 1,400 MW of wind power investment in energy efficiency, including smart metering. The ESB proposes to halve its carbon emissions within 12 years, delivering one-third of its electricity from renewable generation, and achieve carbon net zero by 2035. It seems likely that some of this investment will correct for market failures e.g. in energy efficiency via smart meters, and that there is a case for allowing all of the value of the pass through to be held by the company to help fund this investment However, it is important to formalise the analysis to see that such is the case. This would also help decide what policy should be in relation to the surplus likely to accrue to the other companies. Other Utilities A similar logic applies to the other utilities. The aggregate surplus accruing over 5 years is estimated to fall in the €174-269 million range (Table 3). The CER has been struggling to encourage sufficient capacity to provide competition to the ESB, so there may be reluctance to impose requirements on those new entrants who have come into the market. However, this needs to be balanced by the fact that consumers are providing them with a gain for which they have not paid, and a quid pro quo is appropriate, perhaps with a focus on energy efficiency. The Kema (2008) 9Assuming average price per tonne of CO2 of €23, and – following Sijm et al. (2006) – an average pass through of 50 per cent.

This reflects both the nature of electricity use in society and also the losses associated with its generation.

The key features are: • Cap tightening – stepwise reduction of total allowances by 20 per cent by 2020. • Centralisation (’harmonisation’) of – cap fixing, allocation, monitoring verification and enforcement. • Auctioning of allowances, with focus on the power sector. • Leakage provisions for the non-power sectors – more free allowances and/or ‘equivalent effort’ required of imports to EU. • Banking (including Certified Emission Reductions (CERs) from CDMs that are already in the second phase ERs) over 13 years – 2008-2020. 11Assuming average price per tonne of CO2 of €23, and – following Sijm et al.

MOBILISING MARKET-BASED INSTRUMENTS FOR CLIMATE CHANGE IN IRELAND 25 • CERs post 2012 parked pending UN agreement. • Exclude small-scale installations (but require “equivalent effort”?). • Effort sharing – distribute 10 per cent of auctioned allowances to poorer Member States. These measures are to be welcomed for a number of reasons: Auctioning will remove the advantage which free allocation gives to incumbents. It will also generate revenues which will accrue to the member states and can be used inter alia to reduce other taxes, intensify carbon reduction effort elsewhere and provide support for poorer people who are particularly disadvantaged by higher prices. The long period of banking and borrowing will allow smoothing of the market thereby reducing price swings. Innovation in new carbon reducing technologies will be stimulated by the longer time horizon, the more stable prices and the guarantee that there will be an immediate cash payoff to reductions. The ESB’s strategy of investing in carbon reducing technologies will have the commercial benefit to them of reducing the volume of allowances that they will need to buy to cover their emissions, to the point that they may become exporters of allowances. COMPETITIVENESS ISSUES No significant issue in this regard has arisen during the pilot phase, with net outgoings being less than would be paid for an acre of land in Dublin’s city centre. Short Term (2008-2012) There are short-term issues in the second period arising from the free allocations. When low carbon competitors come into the Irish market, it is crucial that the incumbent advantage of free allocation not be allowed to disadvantage such new entrants. There is a systematic tendency for the non-utility firms to be treated generously. Excluding cement, their emissions are small: generally a lot less than 100,000 tonnes annually. Those of some significance as regards volume are the Conoco Phillips Whitegate Refinery (Relevant Emission of 372,094; allocation 389,164), Bord na Móna briquette factories at Derrinlough (relevant emission 68,343; allocation 71,478) and Littleton (relevant emission 67,180; allocation 70,261), Diageo Dublin (relevant emission 70,681; allocation 73,924). Each of the four largest cement installations received 96 per cent of their relevant emissions, based on a pro rata allocation of the sectoral envelope. If the construction industry grows, and cement holds or grows its share, then these firms – CRH and Quinn – will have to buy allowances to cover their emissions at the margin. Conversely, if construction declines and/or they lose market share, then they could end up with more allowances than they need, and be able to sell these in the market place. 26 BUDGET PERSPECTIVES 2009 Longer Term (2013-2020) While allowances to the utility sector will be auctioned, the issue of auctioning allowances for the non-utility sectors in the scheme is left more open, depending in part on the credibility of the evidence regarding competitiveness issues. Going forward, the Commission proposes a two step approach. Identify the extent to which such issues are relevant at the sectoral level. If there is evidence of negative competitive effects, two possible solutions – requiring ‘equivalent effort’ from companies selling into the EU, in the sense of buying allowances to cover the emissions that were emitted, or giving European producers free allowances. These options are currently being debated. CARBON TAX AND TRADING The firms in the trading scheme have shown that they can adapt to the market. They are faced with a price signal in the Euro 20-30 range that tells them 24 hours a day, 365 days a year, that, if they reduce emissions at a cost below this level, they can sell the allowances released at a profit. It would be redundant and economically inefficient to apply a carbon tax to those in the trading sector, for the following reasons: individuals and firms adjust at the margin to approximately make the costs and benefits at the margin equal, and diminishing returns sets in – the more you do, the more expensive it becomes. Efficiency for a particular objective is maximised if the returns at the margin across all the abators is equal. So we recommend that the carbon tax only be applied to those not in the trading scheme. The scale of the challenge, in terms of meeting the Commission’s target of a 20 per cent reduction in the non-trading sectors is clear from the Table below. Table 4: Emissions from the Non-Trading Sector in 2005, and Hypothetical Targets for 2020 to Meet the EU Cap Sector Emissions in 2005 Million Tonnes of CO2 Equivalent Per Cent of Total Target if Each Sector Reduced Pro Rata by 20 Per Cent in Tonnes of CO2e Reduction Needed in Million Tonnes of CO2e Agriculture13 19.6 41.3 15.7 -3.9 Transport 13.0 27.4 10.4 -2.6 Residential (non-electric only) 6.9 14.6 5.5 -1.4 Service Premises (private offices and public buildings) 2.9 6.1 2.3 -0.6 Waste 1.8 3.8 1.4 -0.4 Other (industry not in EU ETS, tourism etc. 3.2 6.8 2.6 -0.6 Total 47.4 100 37.9 -9.5 13Most emissions from agriculture and waste are methane. MOBILISING MARKET-BASED INSTRUMENTS FOR CLIMATE CHANGE IN IRELAND 27 Note that this scenario assumes that emissions in 2020 will equal those in 2005, which is a highly conservative assumption.14 But even with this context, we have to squeeze almost 10 million tonnes of emissions out of the system over 12 years, in a context where emissions from agriculture only reduced by 0.7 million tonnes (from 20.3 to 19.6 million) over the 1993-2005 period, and emissions from transport rose by 7.2 million tonnes (from 5.8 to 13.0 million) over the same period. What role can a carbon tax play in meeting this challenge? This is the topic to which we now turn. A carbon tax is a tax on the emissions of carbon or carbon dioxide and is a favoured instrument for economists to reduce CO2 emissions due to its cost-effectiveness. Unlike international oil price rises, which benefit foreign producers, the revenues from carbon taxes can enable other taxes to be reduced, vulnerable households to be helped and the energy-efficiency of their homes to be upgraded. 4. Carbon Tax in the Non- Trading Sectors As with all market-based instruments the relative increase in the cost of emitting carbon coaxes people to adjust their habits to dearer energy. The goal is to ultimately reduce carbon emissions by sending a price signal to businesses and consumers so that they change their behaviour. By giving users the choice to either reduce their emissions or to pay the tax, carbon taxes are cost effective since generally firms and users with the least abatement costs undertake abatement first. There is also dynamic efficiency, as carbon taxes incentivise firms to invest in technological innovation that will allow them to continually improve their emissions reductions. Inventors of clever ways to reduce energy use now face customers whose interest is enhanced by the true value of the savings that efficiency will bring them. Carbon taxes are a price-based instrument, compared with emissions trading which is based on emissions quantities.15 There are advantages and disadvantages to both in their implementation but theoretically, if emissions permits are auctioned in perfect market conditions then both instruments can be equivalent. As with all policy, it is the design of policy measures which determine their success or failure under the usual criteria of static and dynamic economic efficiency, environmental effectiveness, socio-economic impacts, and political/public feasibility. Taxes on income and labour have a tendency to discourage work while taxes on pollution discourage pollution. Therefore, raising the same amount of revenue but via more pollution taxes and lower labour taxes helps make the economy more efficient while lowering pollution. Aggregate taxes do not rise but they are raised in a smart manner. Similar arguments can be made for emissions trading systems where emissions permits are auctioned and the revenue used to reduce other taxes. There 14Recent EPA projections suggest that in 2020 the non-ETS sectors will generate 53.3, 52.0, and 44.9 Mt CO2 under their baseline, “with measures”, and “with additional measures” scenarios respectively. 15In the cap-and-trade version of ETS, a cap is set on the total emissions permitted from the sectors included in the scheme. 28 BUDGET PERSPECTIVES 2009 are now several Member States with Environmental Tax Reform (ETR) in place and the COMETR project has carried out an ex-post assessment of the experiences of seven EU Member States with ETR and finds that there are largely positive effects (see Box 1). The Programme for Government agreed in July 2007 states that: Appropriate fiscal instruments, including a carbon levy, will be phased in on a revenue-neutral basis over the lifetime of this Government. The environment subgroup of the Commission on Taxation was established in March 2008 …to investigate fiscal measures to protect and enhance the environment including the introduction of a carbon tax. A carbon tax has been discussed in the Irish context repeatedly since Fitz Gerald and McCoy first explored the options for implementation of a carbon tax in Ireland in their seminal paper in 1992. Further work was carried out subsequently on the impact of a carbon tax on the Irish economy (Bergin et al., 2004; Smith, 2003; Wissema and Dellink, 2007; Fitz Gerald et al., 2008; and Tol et al., 2008) and examining the distributive effect on households (Scott and Eakins, 2004; Tol et al., 2008). The Department of Finance considered the introduction of a carbon tax in 2003 and opened a public consultation on the issue.16 Subsequently, a report was produced summarising the 117 submissions and in September 2004 the Minister for Finance, Charlie McCreevy, announced that the carbon tax would not be implemented. The reason given was that …the environmental benefits would not justify the difficulties that would arise, particularly for households, from the introduction of such a tax. There was insufficient political will to implement a policy with such a high level of public unpopularity. Box 1: Evidence from Other EU Member States The COMETR project examined the experience of six countries on the issues of competitiveness, carbon leakage, mitigation, and compensation with respect to Environmental Tax Reform (ETR). The study concludes that while the environmental taxes implemented were “relatively modest”, they have contributed to greenhouse gas emissions reduction of between 1.5 and 6 per cent in 2004 compared to business as usual. It is estimated that by 2012 the effect will comprise a reduction of up to 7 per cent below the outcome without the tax reform. In addition it is calculated that the tax reform has produced a modest but significant positive effect on economic growth. This has arisen because carbon taxes have led to energy efficiency gains and lower wage costs. The study found that there are winning and losing sectors under the reform and that overall there has been an economic advantage for five of the six countries studied. In the UK the reform was found to have a neutral effect on the economy, but it was noted that the scale of the tax rates levied there has been modest and it is also the most recent environmental tax reform. It appears to make a difference whether energy prices or taxes increase. The main reason for this is that with energy price rises the additional revenue does not return to the public domain but is exported whereas domestic taxes can be used to lower other taxes. In addition, domestic 16http://www.finance.gov.ie/viewdoc.asp?DocID=1778 MOBILISING MARKET-BASED INSTRUMENTS FOR CLIMATE CHANGE IN IRELAND 29 taxes are not levied on non-fuel imported raw materials and intermediate goods and this can have implications for firm competitiveness.17 Figure 1: The Effect* of Green Tax Reform (ETR) on Economic Growth *The effect is measured as the difference between the baseline and the reference case of ETR. Slovenia has not introduced green tax reform, but has adjusted energy taxes in the industrial sector according to CO2-content. Source: Cambridge Econometrics.18 A Commission on Taxation has been re-formed in 2008 with an environmental subgroup to examine again the potential introduction of a carbon tax and it is interesting to consider how to resolve the perceived obstacles from 2003. The following concerns are often raised in arguments against a carbon tax: • Not effective in terms of CO2 emissions reduced – while energy prices have risen over the past years, energy consumption has also risen; • Most of industry is already part of the EU ETS and carbon taxation would lead to double taxation; • Reduction in industry competitiveness; • Issue of fuel poverty among low income households; • Inequitable burden on rural dwellers due to high price of transport fuels. Carbon taxation is a contentious issue, particularly in a world of high energy prices. An important argument in its favour is our high level of greenhouse gas emissions and the fact that we have legally binding commitments under European Union law which are proving expensive to meet. In the last budget the government set aside €270 million in addition to the previous €20 million in 2005 in order that the government be able to 17COMETR website http://www.dmu.dk/International/News/Archive/2007/CO2tax. htm.

This assumes a purchase price of approximately €15/tCO2 emissions; if this price rises appreciably or Ireland requires even more allowances to meet rising emissions, then the amount required to buy credits could become significantly higher. As noted earlier, these obligations are expected to become more demanding post 2012. Instead of raising general taxes on all taxpayers to buy out our obligations, it makes sense to face every emitter with the cost of their emissions, and encourage them automatically to reduce. This is fair because those who emit most pay most, and it is efficient because the abatement response is left to the emitter. LEVEL AND TIMING OF THE CARBON TAX In the Programme for Government, there is a commitment to reduce emissions to 86 per cent of 2007 levels by 2010. Since this commitment was agreed, the Commission has proposed that Ireland’s emissions from the non-traded sector be reduced by 20 per cent by 2020, perhaps rising to 30 per cent in the event of international agreement. We propose that this Commission target should supercede the programme for government commitment for the following reasons: it ensures consistency between Irish and EU policy, and it allows more time for government business and households to bring forward and implement reduction strategies that are cost effective. When should a tax be introduced, and at what level? Greenhouse gas emissions continue to rise in the non-trading sectors and policies are needed with immediate effect that begin to arrest this trend and raise awareness as soon as possible. Therefore, the carbon tax should be implemented forthwith, modified if necessary thereafter to ensure consistency with the Commission for Taxation’s proposals. A carbon tax could be phased in, starting with the budget for 2009, initially at a low level, to give businesses and households time to adjust, rising to approximately equal the price of carbon in the emissions trading market so that all sectors are equally treated. This is estimated to be about €25/tCO2 in 2012. It takes 3-5 years for most of the incentive effects of a carbon levy to be reflected on the ground and therefore, the tax could be introduced now, even at a low level. SCOPE OF THE CARBON TAX We agree with Tol (2007), Tol et al. (2008) and Fitz Gerald et al. (2008) that sectors already included in the ETS should be exempt from the carbon tax. The scope of the EU ETS is fixed for now and unlikely to be extended to other sectors in the near future. Although most allowances were grandfathered to the sectors in the EU ETS, there is evidence to suggest that carbon prices will be passed through to consumers and, therefore, as discussed in the previous section we do not propose that ETS sectors be liable for a carbon tax. It can be expected that the cost to firms in the ETS of ‘acquiring’ permits will mean the cost of using permits by emitting CO2 and these costs will be passed through to consumers even if extra permits are not purchased. As noted, it is proposed that allowances in EU ETS be auctioned from 2013. While the tax in principle should cover all of the non-traded emissions, there would be difficulties in implementing such a tax to diffuse non-point sources, such as agriculture. So we propose that the tax initially apply to the rest of the non-traded sectors – transport, MOBILISING MARKET-BASED INSTRUMENTS FOR CLIMATE CHANGE IN IRELAND 31 residential, services, waste industry not in EU ETS – with a separate ‘equivalent effort’ provisions to apply to agriculture. Concerns with social equity should be addressed through the use of revenue from the tax and we will discuss this in a later section. POTENTIAL CO2 EMISSIONS REDUCTIONS A study by Kema (2008) for Sustainable Energy Ireland focused on opportunities to achieve energy efficiency in the residential, commercial and industrial sectors. It identifies substantial economic potential for carbon savings in electricity, oil and gas, where ‘economic’ is defined as “those measures that are cost effective under current conditions.”19 It does not address agriculture and transport, and does not distinguish between the traded and the non-traded sectors. Estimates of the costs and potential for emissions reduction are also found in ICF Byrne Ó Cléirigh (2006) in their analysis of the marginal costs of abatement prepared for the Department of the Environment, Heritage and Local Government as background for the development of the National Allocation Plans for EU ETS. Their analysis does recognise the distinction between trading and non-trading sectors, and includes agriculture and transport. Although they are difficult to compare, because of the different focus and scope, the ICF Byrne Ó Cléirigh analysis seems to be much more conservative as to what can be achieved at what cost. An estimate of the impact of a carbon tax of 20€/tCO2 on emissions from the non-trading sectors excluding agriculture was included in the Comhar SDC submission to Budget 2008. CO2 emissions reductions were estimated using long run (3-5 years) elasticities and resulting CO2 percentage changes for households (-3.1 per cent) and industry (-4.3 per cent) from ESRI, road haulage transport using elasticities from Bjørner, (1999) (-0.1),20 road transport (cars) (-0.17) from Ryan et al. (2007)21 and it is assumed that the elasticity for service premises is equal to that of industry. This led to estimated savings of 469kt CO2 emissions based on 2005 values, which is similar to the 500kt estimated in the Department of Finance consultation document produced in 2003. The literature in this area has examined the impact of different carbon price levels on Irish CO2 emissions. Bergin et al. (2004) found that a carbon tax of €20/tCO2 emissions would not reduce emissions sufficiently to meet Ireland’s target in 2012 of 13 per cent emissions increase compared with 1990 under the EU burden-sharing agreement. However, Wissema and Dellink (2007) find that a carbon tax of approximately €10-15/tCO2 would result in a reduction of 25.8 per cent compared with 1998 levels, which would achieve Ireland’s 2012 target. More recently FitzGerald et al. (2008) and Tol et al. (2008) find that a carbon tax set approximately equal to the emissions trading price, i.e. €20/tCO2 in 2012 and €38/tCO2 in 2020 would reduce CO2 emissions from the non-ETS sectors by a modest amount 19Amounting to 3.759, 1.868 and 0.714 million tonnes of CO2 respectively. 20Bjørner, T.B.

Ferreira, and F. Convery (2007). “The impact of fiscal and other measures on new passenger car sales and CO2 emissions intensity: Evidence from Europe”, ongoing research. 32 BUDGET PERSPECTIVES 2009 (523kt) and would not achieve the proposed 2020 CO2 emissions target. However, these are in part a function of the use to which the carbon tax revenue is put, which is the subject of the next section. The announcement of the introduction of a carbon tax has an important impact on reducing carbon emissions in advance of the actual implementation of such a scheme. In the UK, study of the impact of the climate change levy (CCL) shows that there is a much stronger “announcement effect” than “price effect” on emissions reductions.22 They estimate that the announcement effect of the CCL on its own (i.e. without price effects from the imposition of the CCL) caused a reduction in energy demand from other final users of 4.0 per cent in 2001, then 8.4 per cent in 2002, and this is expected to rise to 13.8 per cent in 2010. This includes the feedback effect of lower demand causing lower electricity prices, which reduced the announcement effect’s impact. The modelling work described above regarding an Irish carbon tax does not include any additional effects such as the “announcement” effect and therefore, it may be that the introduction of a carbon tax in Ireland would have a stronger impact on CO2 emissions than the models have indicated. Box 2: UK Climate Change Levy and Agreements In the UK a climate change levy was announced in 1999 and implemented in 2001. We have examined this levy for comparison with a potential carbon tax in Ireland. First, there is a fundamental difference in that the UK climate change levy is only applied to industry, commerce and the public sector. It does not apply to fuels used by the domestic or transport sector, fuels used for the production of other forms of energy (e.g. electricity generation) or for non-energy purposes; it also does not apply to energy used by registered charities for non-business uses, and energy used by very small firms.23 The levy is not charged as a function of the carbon content of fuels but is levied directly on the energy type. Businesses that are part of the climate change negotiated agreements and who meet their energy reduction targets are eligible for an 80 per cent rebate in the climate change levy. Businesses that are part of the negotiated climate change agreements are also eligible to join the emissions trading scheme to buy allowances beyond their target. In this way firms either meet their agreement target through their abatement efforts or by purchase of emissions allowances and pay 20 per cent of the climate change levy, or they do not and pay the tax. 22Cambridge Econometrics (2005). “Modelling the initial effects of the climate change levy”.

The levy is expected to raise around £1 billion in its first full year (2001/02). The levy package is expected to lead to reductions in carbon dioxide emissions of at least 2.5 million tonnes of carbon a year by 2010. http://www.defra.gov.uk/environment/climatechange/uk/business/ccl/intro.htm [accessed October 8, 2007]. http://customs.hmrc.gov.uk/channelsPortalWebApp/channelsPortalWebApp�.portal?_nfpb=true&_pageLabel=pageImport_ShowContent&propertyType=document&columns=1&id=HMCE_PROD1_023971#P15_3004 http://customs.hmrc.gov.uk/channelsPortalWebApp/channelsPortalWebApp�.portal?_nfpb=true&_pageLabel=pageImport_ShowContent&propertyType=document&columns=1&id=HMCE_PROD1_023971#P15_3004 http://customs.hmrc.gov.uk/channelsPortalWebApp/channelsPortalWebApp�.portal?_nfpb=true&_pageLabel=pageImport_ShowContent&propertyType=document&columns=1&id=HMCE_PROD1_023971#P15_3004 http://www.defra.gov.uk/environment/climatechange/uk/business/ccl/intro.htm MOBILISING MARKET-BASED INSTRUMENTS FOR CLIMATE CHANGE IN IRELAND 33 REVENUE USE The Medium-Term Review estimates the CO2 emissions from the non-traded sector in 2010 to be approximately 28 MtCO2. 24 This equates to a revenue stream of around €550 million (for a carbon tax of €20/tCO2) and is forecast to grow annually by between 7.2 per cent and 8.2 per cent, depending on whether all greenhouse gas emissions are included or just CO2 emissions and whether ETS permits are auctioned. Therefore, the revenue from a carbon tax is expected to be significant and there are several options for its use. The Programme for Government states that the carbon levy or tax should be revenue neutral which means that the revenues from the levy should be recycled back to the citizens – taxes should not be increased but rather the tax base shifted in favour of carbon emission reducing activities, or the money should be returned. How exactly this is done is a key determinant of (a) environmental performance, (b) economic competitiveness, and (c) public acceptability. The latter is becoming increasingly important in the face of rising energy prices. There are three broad categories of use for carbon tax revenue generally discussed – hypothecation for investment in environmental activities, macroeconomic adjustment such as a reduction in labour taxes, and finally, compensation to households for distributive effects. The first option is to recycle some or all of the revenues from the carbon tax to the different sectors in approximate proportion to their payments, and in manners that further intensifies and incentivises actions to reduce emissions and to address some of the equity and competitiveness concerns associated with a carbon tax. In general, economists prefer that the revenue from environmental taxes not be set aside or hypothecated for greenhouse gas emissions saving activities. The argument is mainly that it reduces the flexibility of the government budget and also that if an activity is not worth subsidising from the national budget then it is also not worth subsidising with the carbon tax revenue (Tol et al., 2008). The latter point assumes that government already has in place a system for the efficient allocation of public expenditure. There is the risk that if significant funds are earmarked for investment in specific activities then they may be wastefully spent in order to “use up” the funds. However, there are some advantages associated with a decision that some of the carbon tax revenue should be invested in further greenhouse gas emissions savings activities. The experience of Sustainable Energy Ireland through the pilot negotiated agreements programme with industry in 2002 showed that the emissions savings were almost doubled if a carbon tax was linked with an industry agreement providing energy-saving expertise and services. There is a case to be made that there may currently be underinvestment of the government budget in public good activities such as energy technology R&D, centres providing expertise and advice to firms in energy efficiency and other greenhouse gas emissions mitigation and adaptation activities, which are of little commercial value at this time. In addition, investment in developing alternative energy sources such as renewable energies may reduce the burden of the carbon levy in the long run. 24Note that the emissions forecast is calculated including a carbon tax and, therefore, the emissions have been adjusted to take this into account. 34 BUDGET PERSPECTIVES 2009 Another significant advantage of investment of the revenue in the sectors that have paid the taxes is that it is likely to increase the public acceptability and hence, political feasibility of implementing a carbon tax. There is also a fairness aspect; if all the revenue is spent on individuals’ income tax reductions and welfare benefits, then it might be argued that business sectors facing the carbon tax such as road haulage, services sectors etc. also deserve a share of the revenue directly.25 There may be a case for using some of the revenue to increase stakeholder buy-in to a carbon tax scheme and also to maximise the greenhouse gas emissions savings that could be achieved through investment in public good activities such as provision of centres of expertise etc. In order to identify the best means to utilise the revenue in each sector, the government could engage with each sector to identify expenditure within the sector that will further reduce emissions. This is consistent with the partnership model that has worked well for Ireland, and should encourage ‘buy in’ as well as increasing the effect on emissions reduction yielded by the incentive effects of the levy alone. The key requirement of any sectoral agreement would be that it significantly and cost-effectively further reduces emissions. While we do not argue that all carbon tax revenue should be spent on investment in climate change- related activities, we believe that more government spending is needed in certain public good activities relating to climate change and that a portion of the carbon tax revenue could be used to fund this. Further study is needed to examine the gaps in current spending and to assess the amounts needed to develop opportunities and technologies to reduce greenhouse gas emissions cost effectively. Regular review would be needed of the amounts spent to ensure efficiency. The Kema (2008) and ICF Byrne Ó Cléirigh (2006) analyses provide contrasting menus of opportunities which need to be investigated further to identify (a) the hierarchy of reduction opportunities that exist, ranked on the basis of cost effectiveness, (b) the government or market failures that are inhibiting the take up of these opportunities and (c) the role, if any, of public expenditure in facilitating abatement. Another option is to use the funds to reduce other taxes and charges, e.g. PRSI, or to provide a lump sum rebate to households. Classical ETR protagonists favour the use of environmental tax revenue to lower other taxes such as on labour. Since carbon tax raises prices and therefore the cost of living too, it would normally be expected that wage demands would also rise. Therefore the revenue from carbon tax could be used to offset some of the increased costs people face by for example reducing income taxes, social insurance contributions, or giving a lump sum to all households. This could be done in line with the Agreed Programme for Government, which has the stated goal of reducing PRSI at 2 per cent to 4 per cent over the term of government. However, the programme also plans to raise the ceiling on PRSI rates so that PRSI can be levied on all income in which case the additional revenue raised would cover the reduction in
