While we have only the foggiest idea of what this would imply in terms of ecological, economic, and so- cial outcomes, it would make most thoughtful people—even economists— nervous to induce such a large environmental change. Given the poten- tial for unintended and potentially disastrous consequences, it would be sensible to consider alternative approaches to global [climate] policies. William Nordhaus, 1997 T ransition to a Low Carbon Economy in Poland is a study by the World Bank for the Polish Government, supported by the UK Department for International Development and donors to the Energy Sector Man- agement Assistance Program (ESMAP). The study poses the question of how Poland, an European Union (EU) member state, an industrialized “Annex 1�1 country for the purposes of international climate discussions, and an Organi- zation for Economic Co-operation and Development (OECD) member, can successfully transition to a low carbon economy as successfully as it under- went transition to a market economy in the early 1990s. Policymakers may find reassuring the main message that Poland’s transi- tion to a low carbon economy, while not free or simple, is affordable. How- ever, capturing the full package of technologically feasible and economically sensible abatement measures requires coordinated and early action by the government. • Poland can cut its greenhouse gas emissions (GHG) by almost a third by 2030 by applying existing technologies, at an average cost of 10 to 15 per ton of carbon dioxide (CO2). In particular, decisions will rapidly need to be made to accelerate energy efficiency, to determine the share of nuclear in the energy supply and to plan for low carbon transport options. 1 Annex 1 countries are 37 industrialized countries and economies in transition parties to UNFCCC which have agreed to emissions reduction targets. • Costs to the economy will peak in 2020, but by 2030, the shift towards low car- bon will augment growth. Overall, this abatement will lower gross domestic product (GDP) by an average 1 percent each year through 2030. • The economic cost in output and employment of Poland’s required abate- ment by 2020 under EU rules is higher than for the average EU country, and the restrictions on emissions trading between sectors aggravate that cost. • The energy sector currently generates near half of Poland’s emissions, but the transport sector—with precipitous growth and the need for behavioral change rather than adoption of new technologies—may end up posing the tougher policy challenge. With the objective of assessing not only the net costs and investment demands but also the macroeconomic implications of GHG mitigation policies, the study uses an integrated approach that combines “bottom-up� engineering analysis with “top-down� economy-wide modeling. The Need to Reduce GHG Emissions There is a broad consensus that an international coordinated response to the threat of climate change is needed. Evidence that the world is warming and that human activity is primarily to blame has continued to accumulate in recent years, as has the understanding that a lack of action will impose very high costs, espe- cially on poorer countries. Under the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC), richer countries, including Poland, committed to reduce GHG emissions by about 5.2 percent during 2008-12 compared to 1990. While Europe will not be among the worst harmed, the EU has taken a proactive stance within the international community’s ongoing negotiations by setting a unilateral target of a 20 percent reduction in emissions by 2020. EU members such as Poland therefore face specific obligations for climate action. Poland faces a particular challenge in CO2 mitigation because of its heavy reliance on abun- dant domestic coal. Poland’s GHG Emissions Poland is not among the largest emitters of GHG globally, but its economy is among the least carbon-efficient in the EU. Poland’s global share in GHG emis- sions is just 1 percent, and its per capita emissions are similar to the EU overall. With 10 tons of carbon per capita in 2007, Poland is exactly at the level of the EU272 average, but given its lower income level, the Polish economy is one of the least carbon-efficient. Poland’s transition to a market economy since 1989 has a co-benefit of sharp- ly reduced carbon emissions (Figure 1); however, the link between growth and emissions has re-emerged in recent years. A critical difference in the make-up of Poland’s emissions is the dominance of the power sector and its extraordi- nary dependence on coal. Over 90 percent of electricity in Poland is generated 2 EU27: Austria, Belgium, Bulgaria, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland, Portugal, Republic of Ireland, Romania, Slovakia, Slovenia, Spain, Sweden, and the United Kingdom. 2 | Low Carbon Growth Country Studies Program Figure 1: Economic Growth and GHG Emissions in Poland, 1988–2008 200 Base year 1988 = 100 150 100 50 88 89 90 91 92 93 94 95 96 97 98 99 0 1 2 3 4 5 6 7 0 0 0 0 0 0 0 0 19 20 19 19 19 19 19 19 19 19 19 20 20 19 20 20 19 20 20 20 Year GDP index, 1988 = 100 CO2 emissions index, 1988 = 100 Source: World Bank, 2011.

Outside the energy sector, Poland’s trans- port sector has experienced very high rates of emission growth. Energy efficiency, although considerably improved over the past 20 years, has not yet reached West- ern European standards. Despite dramatic advances during 1988 to 2000, Poland’s economy is still more than twice as energy intensive as the EU average (Figure 3).

Note: Energy intensity is the ratio of gross inland consumption of energy (in tons of oil equivalent) to GDP (in millions of euros at 2000 prices). Poland’s Carbon Abatement Targets and Policy Challenges The international agreement on climate change that will eventually supersede the Kyoto Protocol and, more immediately, compliance with EU policies on climate change, pose policy challenges for Poland. Poland has been an active participant in international negotiations on climate change, in particular as a signatory to the Kyoto Protocol (Box 1), and as host to the 14th Conference of Parties of the UNFCCC in December 2008. The contraction of GHG emissions that accompa- nied economic restructuring in the 1990s caused Poland to outperform against its Kyoto commitments, and the country continues to exceed its Kyoto targets by a large margin. The most demanding of commitments on emissions, however, comes from EU policies on climate change mitigation. The EU climate change and energy package, or the “20-20-20� targets, requires comprehensive action by EU members to achieve a 20 percent reduction in GHG emissions by 2020, re- newable energy making up 20 percent of energy consumption, and a 20 percent improvement in energy efficiency. The 20-20-20 package requires Poland’s energy-intensive sectors to contribute to the EU target of a 21 percent reduction (compared with 2005) while allowing emissions from Poland’s non-energy sectors to increase by 14 percent. The EU package segments sectors into two groups and sets multiple targets. Large instal- lations in energy-intensive sectors are covered by the EU-wide Emissions Trad- ing Scheme (the ETS sectors), a regional carbon market. Energy, heavy industry, and fuels are ETS sectors. In Poland, approximately 60 percent of CO2 emissions in 2005 were generated in the ETS sectors (compared with about 40 percent in the EU as a whole). For the less energy-intensive non-ETS sectors, the package requires a reduction in emissions by 10 percent compared to 2005 in the EU27. That EU-wide target was translated into a national target for Poland as an in- crease in its non-ETS emissions by 14 percent (Figures 4 and 5). 4 | Low Carbon Growth Country Studies Program Box 1. The Kyoto Protocol of the UNFCCC The Kyoto Protocol is an international agreement linked to the United Nations Frame- work Convention on Climate Change (UNFCCC). While the UNFCCC encouraged in- dustrialized countries to reduce GHG emissions, the Kyoto Protocol set binding tar- gets for Annex 1 Parties—37 industrialized countries, including all members of the European Union—by an average of 5 percent against 1990 levels over the five-year period 2008-2012. Some countries with economies in transition negotiated a pre- transition base year: Bulgaria (1988), Hungary (average of 1985 to 1987), Poland (1988), Romania (1989) and Slovenia (1986). The Protocol was adopted in Kyoto, Ja- pan, in December 1997 and entered into force in 2005. Among industrialized coun- tries, only the United States failed to ratify the Protocol. Countries must meet their targets primarily through national measures, but the Protocol offers three alternative (or flexibility) mechanisms: • International Emissions Trading (“the carbon market�). Annex 1 countries that have emissions permitted but not “used� are allowed to sell excess capacity to other Annex 1 countries. Because CO2 is the principal greenhouse gas, the market is called the “carbon market.� At present, the European Union Emissions Trading Scheme (EU ETS), established in 2005, is the largest in operation. • Clean Development Mechanism (CDM). Annex 1 countries can meet part of their caps using credits generated by CDM emission reduction projects in developing countries. • Joint Implementation (JI). Annex 1 countries can invest in JI emission reduction projects in any other Annex 1 country as an alternative to reducing emissions do- mestically. Source: UNFCCC website.

These sectors (including transport and energy end-use in buildings and households) will require national policies to restrain emissions growth. The EU scheme’s auctions of emission allowances will raise significant revenue for the Polish government in the future, estimated at roughly 1 percent of GDP. This revenue will be inversely related to the share of allowances that the gov- ernment decides to allocate for free to support the competiveness of affected industries. More importantly, this segmented approach raises the cost of miti- gation because of diverging marginal abatement costs across emission sources and sectors. 6 | Low Carbon Growth Country Studies Program Assessing the Impact of Carbon Abatement With a broad consensus that global coordinated action is needed to prevent dan- gerous climate change (estimated to cost about 1 percent of global GDP) and with EU policies on climate change already in place, Poland faces immediate policy questions: • Could the country commit to more ambitious overall GHG mitigation tar- gets for the longer term? • What technological options are available and how expensive are they com- pared with existing technologies? • Will there be high costs in lost growth and employment? • Over a shorter horizon, to 2020, what are the implications for Poland of im- plementing EU policies on climate change? Transition to a Low Carbon Economy in Poland uses four complementary and interlinked models (Box 2), combining a “bottom-up� engineering analysis with “top-down� economy-wide modeling to quantify the economic impact of CO2 mitigation in Poland. This overview highlights the main findings of this analysis. Transition to a Low Carbon Economy in Poland | 7 Box 2. Low Carbon Modeling Suite for Poland Four complementary and interlinked models for Poland were developed to quantify the economic impact of CO2 mitigation, taking advantage of available data and leveraging existing models. The models complement each other; by ensuring that sectoral work pro- vides specific recommendations for actions at the sector or subsector level while the mac- roeconomic modeling ensures consistency of projected sectoral growth rates, with energy demand and other key macroeconomic variables. • MicroMAC Curve—The most familiar of these models is the widely-used Marginal Abate- ment Cost (MAC) curve which provides a simple first-order ranking of technical options for GHG mitigation by sector based on the net present value of costs and savings per metric ton of CO2 equivalent avoided. • Macroeconomic Mitigation Options (MEMO)—A dynamic stochastic general equilibrium (DSGE) model of Poland revised to include energy and emissions, assesses the macroeco- nomic impact of the options costed in the MicroMAC curve. It is linked to the MAC curve via a Microeconomic Investment Decisions (MIND) module which groups the technology levers into seven packages, including an optimized package of options for the energy sector. • Regional Options of Carbon Abatement (ROCA)—A country-level computable general equilibrium (CGE) model for energy and GHG mitigation policy assessment adapted to Poland, analyzes implementation of the EU 20-20-20 policy in the context of global policy scenarios, with an emphasis on spillover and feedback effects from international markets. • TREMOVE Plus—This last model is a detailed sectoral approach for road transport, the sector with the fastest growing emissions and central to Poland’s commitments under EU 20-20-20 (as a non-ETS sector). It makes use of the EU transport and environmental model, TREMOVE, updated with the latest information and policy intentions, here de- noted as the TREMOVE Plus model. All four use very similar “business-as-usual� reference scenarios (within the limitations of data) against which to measure policy changes. The innovative linking of the MEMO econo- my-wide model with the bottom-up engineering approach of the MicroMAC curve model allows analysis of the varying macroeconomic implications of GHG abatement measures, across four public financing options. Figure 6 summarizes the modeling approach. Source: World Bank, 2010. POLAND’S GROWTH PATH WITHOUT A LOW CARBON STRATEGY A business-as-usual scenario is fundamental to the calculation of costs of carbon abatement. If Poland were to take no action (the “business-as-usual scenario�), the models developed (Box 2) suggest that overall emissions in 2020 will stand roughly 20 percent above 2005, while 2030 levels will be 30 to 40 percent higher (Figure 7). However there are significant differences in sectoral details in the reference scenario generated by each model over the 15–25 year analysis (Box 3). This draws attention to the fact that, since each of the models illuminates important aspects of the economics of GHG mitigation, policymakers will need to consider 8 | Low Carbon Growth Country Studies Program Figure 6: Low Carbon Modeling Approach for Poland • Multi-region CGE (international spillovers, pre-existing market distortions, hybrid power sector) • Peer-reviewed model applied to Poland • Impact of EU 20-20-20 package • 8 sectors plus 5 energy subsectors • Poland, rest of EU, other industrialized, developing world ROCA Model Power generation MacroMAC options (activity curve analysis of technologies) • TREMOVE model MEMO (road transport) • Dynamic stochastic Model • 2 scenarios general equilibrium • Passenger, freight (endogenous growth, business cycles) MicroMAC TREMOVE • Poland model + energy Curve Plus and climate redesign • Macro impact of options Model • 11 sectors • Poland; rest of EU MIND module • Marginal abatement cost (optimal energy (NPV cost per tCO2e) package + 6 • ~125 technology options packages of options) • 10 sectors Source: World Bank, 2010. multiple model results, rather than a single answer. Also, over a period of decades, assumptions about efficiency improvements within sectors and shifts towards less carbon-intensive sectors as part of normal development have a large impact (Figure 8): policymakers need to think carefully about country-specific sectoral development in far more detail than economy-wide models such as MEMO and ROCA can manage. POLAND’S ABATEMENT OPTIONS Poland can reduce emissions by 30 percent by 2030 compared to 2005 at an aver- age cost of €10 to 15 per metric ton of CO2 equivalent, according to the Micro- MAC curve, a bottom-up engineering approach. This approach creates a ranking by net cost of about 120 emission reduction options based on existing technolo- gies and presents the measures via a well-known visual summary tool—the MAC curve. When measured against the level of emissions that would otherwise occur in 2030, the reduction is even more significant—47 percent (see Figure 11).

Note: Countries with higher population growth or higher income growth will face faster rising emissions. The emissions elasticity of GDP growth will need to be reduced by even more to offset GDP growth. 10 | Low Carbon Growth Country Studies Program Transition to a Low Carbon Economy in Poland | 11 Box 3. A Comparison of Reference Scenarios for Poland The projected pattern of emissions across sectors varies across models driven by the use of alternative methodologies and separate datasets. This has important implications for the kind of mitigation options that will be relevant for Poland, and therefore, the ease of the shift toward a low carbon path. While the overall projections of emissions for 2020 are similar across models, the MEMO projections indicate a heavier burden for ETS sec- tors, while according to ROCA projections, the major challenge will be faced by the non-ETS sectors. While the MEMO scenario projects ETS sectors to expand by 20 percent relative to 2005 by 2020, the ROCA scenario predicts constant emissions during the period. The MEMO projections seem to indicate Poland will have little problem fulfilling the country-specific target for the non-ETS sectors under the EU 20- 20-20 package (since the projected 15 percent increase under busi- ness-as-usual is very close to the 14 percent increase ceiling). In con- trast, the ROCA projections warn of a significant challenge for non-ETS sectors, with emissions increasing by 46 percent between 2005 and 2020 (Figures 9 and 10). The projections for 2030 are somewhat divergent: the MEMO busi- ness-as-usual scenario for 2030 emissions is 9 percentage points high- er than the projection made in the MAC curve model. 12 | Low Carbon Growth Country Studies Program Figure 9: GHG Emissions in Poland, 2005 and 2020 Scenarios non-ETS ETS Total 0 100 200 300 400 500 MtCO2e 2020~EU targets 2020 ROCA BAU 2020 MEMO BAU 2005 Figure 10: Changes in GHG Emissions in Poland, 2020 Scenarios vs. 2005 14 non-ETS 46 15 Ϫ21 ETS 0 20 Ϫ4 Total 22 18 Ϫ30 Ϫ20 Ϫ10 0 10 20 30 40 50 60 % relative to 2005 2020~EU targets 2020 ROCA BAU 2020 MEMO BAU Source: World Bank, 2010.

Note: Each column is one of about 120 abatement measures. The height of the columns is the cost in € per abated tCO2e. The width is the amount emissions can be reduced against business-as-usual levels projected for 2030. Some measures are shown with net benefits (negative costs). The MAC curve identifies that the majority of Poland’s abatement potential is associated with the switch to low carbon energy supply and with energy efficiency improvements (Figure 12). After implementation barriers are addressed and re- moved, the abatement measures do not have negative net costs and the overall cost of implementing the MAC curve levers will rise by at least 50 percent. To imple- ment all the low carbon levers, additional investment of about 0.9 percent of an- nual GDP will be needed during 2011–30 (Figure 13). Moreover, mitigation mea- sures will take some time to deliver lower emissions, and despite the all-out effort of this abatement package, Poland will just meet its 2020 EU targets (with overall emissions reduction projected for 2020 at about 3 percent below 2005 levels). The Macroeconomic Impact of the Abatement Package Implementation of the full abatement package will reduce growth modestly, costing an average of one percent of GDP each year through 2030. For the com- prehensive abatement package, the MEMO model simulations (Box 4) find that GHG emissions will be reduced by 24 percent by 2020 and by 47 percent by 2030, with an economic impact that is generally negative but appears affordable. Not surprisingly, the fall in GDP is driven by recession in emission-intensive sectors, which bear the heaviest burden of abatement. At a more disaggregated level, the model finds that it is the switch to low carbon energy and fuel efficiency measures that provides the bulk of abatement and that the technologies with the largest abatement potential are not necessarily associated with the biggest macroeco- nomic cost. 14 | Low Carbon Growth Country Studies Program Figure 12: MicroMAC Curve: Abatement Potential for Poland in 2030 by Groups of Interventions GHG emissions MtCO2e annually 525 Share of total abatement Average cost 503 €/tCO2e 500 Business-as-usual % 475 1 Energy e ciency 29% Ϫ14 450 425 400 Low-carbon 386 2 42% 21 375 energy supply 350 325 CCS in power 3 and industry 15% 38 300 Emissions after reduction 275 4 Remaining levers 14% Ϫ1 250 267 Total/Average 236 MtCO2e 10 €/tCO2e 225 Cost of Abatement 200 2005 2010 2015 2020 2025 2030 Year Source: World Bank, 2011.

Transition to a Low Carbon Economy in Poland | 15 Box 4. How Do the Bottom-up Abatement Opportunities Work in the Top-down Model? Switching to lower-carbon technologies, such as wind power, means investing in options with lower net present value (NPV) than traditional coal-fired power plants, the business-as-usual or reference technology in the energy sector. It is as- sumed in the MEMO model, that it is the public sector that covers the additional costs. During the two to five-year construction phase for the new generation plant, investment spending rises in the energy sector. Both the interest rate and the prices of investment goods are pushed up, crowding out capital accumulation in other sectors. Domestic energy prices rise because of higher-priced and expand- ed private investment in the energy sector, and this more costly energy is detri- mental to overall growth. If the public costs are covered by higher taxes, an addi- tional tax distortion is added to the economy. When construction is completed and operations begin, these effects are unwound: energy production becomes cheaper due to reduced fuel costs (since free wind costs less than coal), which leads to lower energy prices. The relative price of investment goods declines, to the benefit of the other sectors which increase their capital accumulation. An energy efficiency measure such as switching to efficient commercial lighting will induce broadly similar effects on investment at the beginning of implementa- tion, balanced by later savings on operational costs resulting from lower energy consumption. As noted above, it will be light rather than heavy industry that bene- fits early on. If the benefits during operation outweigh the initial costs, growth will be enhanced, together with changes in the structure of firms’ intermediate con- sumption. The sectors that have implemented the efficiency measure then enjoy lower costs of production. Source: Authors, 2011. The impact of the entire package on GDP is consistently negative over the twenty-year period of the model, but the losses approach zero by 2030. Losses to real GDP peak in 2020 at near two percent and then gradually diminish, leaving GDP slightly above the business-as-usual level by 2030 (Figure 14). The level of real GDP in 2020 would be from 1.8 to 3.1 percent lower than in the business- as-usual scenario, but by 2030 it would recover to 0.7 lower to 0.7 higher. This U-shaped pattern of GDP impact is driven by the need for upfront investments, with benefits materializing in future years, and in particular, the long lead times required by the power sector. Employment would also suffer, with losses of about one percent of jobs (about 140,000 jobs) on average. The overall employment loss ranges from 2.6 to 0.2 percent reduction compared to the business-as-usual sce- nario. Not surprisingly, the fall in GDP is driven by recession in emission-intensive sectors, which bear the heaviest burden of abatement. Value-added in energy-in- tensive sectors is projected to shrink by more than 9 percent by 2030, with sectoral employment falling by more than 5 percent. The technological micro-packages—groups of related mitigation options— with the largest abatement potential do not necessarily impose the biggest mac- 16 | Low Carbon Growth Country Studies Program Figure 14: Decomposition of GDP Impact of Low Carbon Package, in % 1.5 1.0 Mixed energy/fuel e ciency GDP deviation from BAU, in % Fuel e ciency 0.5 Energy e ciency 0.2 Chemical processes 0.0 Industry CCS and distribution maintenance Agriculture interventions Ϫ0.5 Low carbon energy supply Ϫ0.8 GDP deviation from BAU Ϫ1.0 Ϫ1.5 Ϫ1.5 Ϫ1.8 Ϫ2.0 2015 2020 2025 2030 Source: World Bank, 2011.

Energy efficiency measures are most important in the early years, contributing 20 percent of mitigation in 2015, but costing over one per- cent in GDP losses (Figure 15). From 2020 onward, about 40 percent of poten- tial mitigation derives from energy sector investments and another one-third from fuel efficiency. The switch to low carbon energy (via energy sector in- vestments) and industry carbon capture and storage (CCS) measures together cost about 1 percent per year in lower GDP after 2020, by which time fuel and energy efficiency measures have begun to contribute positively to GDP. Onshore wind and small hydropower plants are superior to many energy efficiency measures by the metric of GDP growth. Nuclear power offers the biggest abatement potential but remains a drain on growth even with a twenty- year horizon—still myopic for plants with 60-year lifespans. Using a macro- economic version of the MAC curve allows detailed examination of the impact on growth associated with the implementation of specific abatement measures (Figure 11). The Macroeconomic Marginal Abatement Cost curve (MacroMAC curve) presents the marginal abatement impact in terms of GDP of each abate- ment option, making it easy to see which measures are “cheaper.� The area un- der the MacroMAC curve defines the overall impact of the entire abatement package on the level of real GDP, an interpretation similar to that of the bot- tom-up Microeconomic Marginal Abatement Cost curve (MicroMAC curve) (in which the area under the curve equals the financial cost of the abatement package). This curve is also generated for 2020, revealing that the impact on GDP of abatement options shifts over time and becomes more positive, flatten- ing the MacroMAC curve as investments are completed and operations begin.

IMPLEMENTING THE EUROPEAN UNION CLIMATE POLICY In complying with the requirements of the EU’s 20-20-20 package, Poland bears a higher economic burden than the average EU country because of the predomi- nance of coal in power generation and the expected strong baseline emissions growth in sectors such as transport. The ROCA model (Box 2) considers several variations on EU climate policy design that meet the same emission reduction targets to further illuminate the impact on Poland’s economy in 2020. The “Main�’ scenario (Table 2) demonstrates this increased economic bur- den because of Poland’s dependence on coal in power generation. The market segmentation created by the EU’s division of economic sectors according to energy intensity greatly elevates the marginal cost of abatement for less energy- 18 | Low Carbon Growth Country Studies Program Table 2: Summary of Scenario Characteristics Simulated in the ROCA model Scenario Basic assumptions All scenarios Emission reduction targets for 2020 are set as in EU climate package and 1.

Transition to a Low Carbon Economy in Poland | 19 intensive industries: marginal abatement costs in these sectors for both Poland and the rest of the EU are almost three times the cost for energy-intensive sec- tors. Removing that segmentation reduces overall compliance costs for Poland. Similarly, allowing emission reductions in the least-cost locations dramatically reduces compliance costs and the need for adjustment, as most abatement is off-shored. An additional aspect of EU policy is incorporated into the ROCA model— overlapping regulation in the form of an EU target for renewable energy sourc- es—to determine conditions in which it may be welfare-improving. The model considers various policy choices under the control of the Polish government. First, alternative revenue recycling via wage subsidies are analyzed, which gen- erates a weak “double dividend� (reducing emissions while easing distortions in the labor market) and lower unemployment. Then, the loosening of restric- tions on the scope of nuclear power is found to cut compliance costs for Poland by about one-third. Lastly, the granting of free emission allowances to energy- intensive and trade-exposed sectors, which might be vulnerable to carbon leak- age, preserves sector output but generates overall losses in GDP. 20 | Low Carbon Growth Country Studies Program Figure 16: EU 20-20-20 Package: Carbon Prices and Macroeconomic Impact Carbon Prices Macroeconomic Impact 100 1.0 Deviation from BAU in % 0.5 0.5 0.2 80 US$ per tCO2 0.0 60 Ϫ0.5 Ϫ1.0 Ϫ0.6 Ϫ0.7 40 Ϫ1.5 Ϫ1.4 20 Ϫ2.0 Ϫ2.5 Ϫ2.7 0 Ϫ3.0 ETS Poland EU GDP EITE UR GDP EITE UR non-ETS non-ETS Poland EU Source: World Bank, 2011. Note: EU26 is the rest of the EU excluding Poland. The carbon price in non-ETS sectors is a shadow price. EITE is energy-intensive and trade-exposed sectors. UR is the change in unemployment rate in percentage points. The findings of the “Main� scenario illustrate that Poland bears a higher eco- nomic burden than the average EU country because of its relatively high abate- ment targets for non-ETS sectors with strong baseline emissions growth. Setting a non-zero price of carbon generates a negative shock to emissions-intensive sectors. Since power generation in Poland is predominantly coal-based, it will be hard hit. CO2 reduction from the sector takes place through rising electricity prices (by about 20 percent, much more than in the rest of the EU), a decline in output by about 10 percent, the expansion of CO2-free renewable power produc- tion, and, to a more limited extent, fuel shifting to gas (since nuclear power is assumed restricted to business-as-usual levels). The higher costs of production for those sectors in which fossil fuel energy inputs represent a significant share of direct and indirect costs leads to a loss in competitiveness, depressing production. In the new equilibrium, real wages are lower, and unemployment rises marginally by only half a percentage point. The effects on real GDP are modest but more than twice as high for Poland as for the rest of the EU (with a loss of 1.4 percent of GDP) (Figure 16). Energy-intensive and trade-exposed (EITE) industries are not devastated by carbon abatement, but market segmentation drives the marginal cost of abate- ment in non-ETS sectors to almost three times the level in ETS sectors. Even for EITE industries (a subset of ETS sectors) worried about loss of competitiveness, the contraction is still moderate in size (although they are harmed more than the average, with 2.7 percent loss in output in 2020 compared to GDP losses of 1.4 percent). At the same time, marginal abatement costs in the non-ETS sec- tors for both Poland and the rest of the EU are much higher than the ETS value (at a shadow price of US$80 per tCO2 for Poland, and US$82 for other EU), revealing less potential for cheap emission abatement in the non-ETS sectors. The differences between ETS and non-ETS prices drive the direct excess costs of EU emission market segmentation, which are alleviated to some degree through limited low-cost offsets from developing countries (via the Clean Development Mechanism of the Kyoto Protocol). Transition to a Low Carbon Economy in Poland | 21 LOW CARBON INTERVENTIONS Transition to a Low Carbon Economy in Poland identifies energy sector invest- ments, end-user energy efficiency measures and transport policy as the central pil- lars of Poland’s transition to an economy with lower GHG emissions. Optimizing Future Power Supply Options The power sector is the dominant source of today’s emissions but the sector’s large investment costs raise financing challenges while long lead times guarantee that its structure will shift only slowly (Table 3, Figure 17). The combination of technologies chosen or new investments will depend not only on capital costs, operational savings, and carbon abatement potential, but also on energy security, domestic sourcing, and other issues. The ROCA model’s results argue that a strong shift towards nuclear power is the option most likely to re- duce emissions without harming the economy. The MEMO model, which takes the most sophisticated ap- proach to selecting the structure of the sector, uses an optimization model to determine the cheapest feasible energy-mix package within multiple constraints. How- ever, even if a full low carbon package is implemented, coal will likely remain the fuel for half of Poland’s elec- tricity in 2030. The average age of Poland’s energy in- frastructure is high. Replacement of this infrastructure provides opportunities for the country to come in line with the low carbon agenda.

Energy Efficiency: Benefits Can Be Realized Relatively Quickly With lower capital costs and earlier returns, end-user energy efficiency mea- sures3 hold out the promise of relatively low cost abatement that works directly to delink carbon from growth, the essence of a low carbon economy. Energy ef- ficiency measures play a central role in the MicroMAC curve analysis (Figure 18) because of their substantial potential, apparent low price, and impact on growth. While it is logical that abatement measures cannot in reality have negative net costs, ascertaining the details of the relevant implementation barriers for these measures is a challenge. Exploiting the energy efficiency agenda will not be easy, but it likely does have some opportunities that are “win-win,� with benefits real- ized relatively quickly and relatively low upfront costs. Initial analysis of the macroeconomic impact of energy efficiency measures (Figure 19) in the MEMO model found that although most energy efficiency measures individually have little potential, if they could be grouped together for implementation, they could be an important carbon abatement tool. Deeper detailed analysis of energy ef- ficiency options in Poland is needed to be able to provide more specific recom- mendations on how to overcome implementation obstacles that are preventing households and businesses from realizing the financial savings embedded in many of these measures. 3 End-user energy efficiency measures include dozens of measures in commercial and residential buildings, such as improved insulation, more efficient lighting, and more efficient appliances, as well as energy-saving measures in industry, such as co-generation.

Road transport GHG emissions in Poland are converg- ing from a low historic base towards EU averages. While contributing about 10 percent of overall emissions, road transport constitutes about 30 percent of non-ETS emissions. The objective of sustainability and greening of the trans- port sector is not new for the EU, but the EU 20-20-20 climate package is now the centerpiece. A business-as-usual scenario through 2030 was developed for passenger and freight road transport in Poland, using the TREMOVE Plus model (Table 4, Fig- ure 20). This forecast incorporated key characteristics of Poland’s transport sec- tor, in particular, a high number of imported used cars, low motorization rates and low mileage, and a highly competitive freight sector that has been shifting to newer and bigger trucks. Emissions from road transport are expected to almost double between 2005 and 2030. Because steady technological improvements are already incorporated into the business-as-usual projections, the two low carbon scenarios developed by the TREMOVE Plus model include only modest techno- logical improvements and concentrate on other emissions-reducing policy mea- sures. The results of the scenarios present a more worrying vision than previously established for the road transport sector, with abatement unlikely to hold emis- sions growth below 35 percent through 2020. With most technological solutions already in place, more difficult behavioral change will be needed, such as shifting away from private cars towards public and non-motorized transport. However, even proactive abatement policies are unlikely to hold emissions growth within the EU target for these sectors. Transition to a Low Carbon Economy in Poland | 25 Table 4.

Note: Precautionary scenario contains policy measures such as road pricing, fuel tax in- creases, and eco-driving. Proactive scenario contains same measures but with greater effort. Technology scenario contains policy measures for modest technological improvement in trucks (medium and heavy duty vehicles). 4  assenger cars achieve lower emissions by improving fuel efficiency, but people then tend to drive P more. This rebound effect can be eliminated by a fuel tax that is linked to the emissions standard. 26 | Low Carbon Growth Country Studies Program CONCLUSIONS Transition to a Low Carbon Economy in Poland provides a detailed assessment of many aspects of a low carbon growth strategy for Poland, developing insights via a suite of models that should provide ongoing assistance to policymakers. These policymakers may find reassuring the main message that Poland’s transition to a low carbon economy, while not free or simple, is affordable. However, capturing the full package of technologically feasible and economically sensible abatement measures requires coordinated and early action by the government. With an ambitious approach, Poland can aim to reduce its GHG emissions by about one-third by 2030 (relative to 1990) with little cost to incomes and employ- ment. Similarly, meeting the EU targets for 2020, while likely more challenging for less energy-intensive sectors such as transport than for sectors that can access the efficiencies of EU-wide carbon trading, are fully possible for Poland with modest cost. Poland has already weathered one economic transition and emerged with a strong and flexible economy. This next transition—to a low emission growth path—while requiring an evolution in lifestyles and priorities over the next 20 years, may well turn out to be much easier.   Transition to a Low Carbon Economy in Poland | 27 REFERENCES Nordhaus, W. 1997.
