Hot air for sale: a quantitative assessment of Russia’s near-term climate policy options

Since January 2005 the European Union has launched an EU-internal emissions trading scheme (EU ETS) for emission-intensive installations as the central pillar to comply with the Kyoto Protocol. The EU ETS will be linked to a Kyoto emissions market where greenhouse gas emission allowances of signatory Kyoto countries can be traded. In this paper we investigate the implications of Russian market power for environmental effectiveness and regional compliance costs to the Kyoto Protocol taking into account potential linkages between the Kyoto emissions market and the EU ETS. We find that Russia may have incentives to join the EU ETS as long as the latter remains relatively separated from the Kyoto international emissions market. In this case, Russia can exert monopolistic price discrimination between two separated markets thereby maximizing revenues from hot air sales. The EU will be able to substantially reduce compliance costs if it does not restrain itself to EU-internal emission regulation schemes. However, part of the gains from extra-EU emissions trading will come at the expense of environmental effectiveness as (more) hot air will be drawn in.      

Carbon Trading with Imperfectly Observable Emissions

The Kyoto Protocol foresees emission trading but does not yet specify verification of (uncertain) emissions. This paper analyses a setting in which parties can meet their emission targets by reducing emissions, by investing in monitoring (reducing uncertainty of emissions) or by (bilaterally) trading permits. We derive the optimality conditions and carry out various numerical simulations. Our applications suggest that including uncertainty could increase compliance costs for the USA, Japan and the European Union. Central Europe and the Former Soviet Union might be able to gain from trading due to higher permit prices. Emissions trading could also lower aggregate uncertainty on emissions.     

The regulatory choice of noncompliance in emissions trading programs

This paper addresses the following question: To achieve a fixed aggregate emissions target cost-effectively, should emissions trading programs be designed and implemented to achieve full compliance, or does allowing a certain amount of noncompliance reduce the costs of reaching the emissions target? The total costs of achieving the target consist of aggregate abatement costs, monitoring costs, and the expected costs of collecting penalties from noncompliant firms. Under common assumptions, I show that allowing noncompliance is cost-effective only if violations are enforced with an increasing marginal penalty. However, one can design a policy that induces full compliance with a constant marginal penalty that meets the aggregate emissions target with lower expected costs. This last result does not depend on setting an arbitrarily high constant marginal penalty. In fact, the marginal penalty need not be higher than the equilibrium marginal penalty under the policy with the increasing marginal penalty, and can actually be lower. Finally, tying the marginal penalty directly to the permit price allows the policy objective to be achieved without any knowledge of firms’ abatement costs.     

Construction of legal system of carbon emissions trading in China

Countries in the world have taken a variety of means to control carbon emissions based on the serious situation of global warming,the concept of low-carbon economy and the provisions about emissions in the United Nations Framework Convention on Climate Change（UNFCCC） and the Kyoto Protocol.With the measures of emissions reductions,the system of carbon emissions trading is taking shape.It is necessary for China as the big natural resources consumption country to establish its own carbon emissions trading system.By introducing the carbon emissions trading system of the European Union,America and Japan,and analyzing the market and policies been formed,the carbon emissions trading system in China can be established from the initial configuration of the emissions rights,the subject and object of carbon emissions trading,establishing the carbon emissions trading exchange and supervising and regulating the carbon emissions trading.     

排污权交易政策对企业环保行为的传导机制研究

从企业的目标函数和生产函数两个角度出发,分析了排污权交易政策对企业环保行为的影响机理,并讨论了排污权交易政策下企业的环保行为选择。研究发现：排污权交易政策通过影响企业的资本要素分配,从而影响企业环境资源的使用成本,进而影响企业的生产和环保行为决策;在排污权交易政策的作用下,企业主要采取不同的污染治理投资策略来满足该政策的规制。基于此,政府应制定配套政策和措施,引导企业沿着“政策遵从—环保投资策略—新环保技术采纳”的行为选择路径进行行为决策,以实现排污权交易政策的目标。     

Carbon Trading Reporting: The Case of Spanish Companies

Policy makers, scientists, industry leaders, and academicians all have debated how to restrain global warming and reduce greenhouse gas (GHG) emissions. Three main methods are used: command and control laws and regulations, carbon taxes, and cap and trade schemes. Recognizing the consequences of global warming, all Scandinavian countries introduced a carbon emissions tax in the 1990s. They also ratified the Kyoto Protocol that ran from 2005 through 2012. The European Union (EU) instituted a carbon trading scheme (Emissions Trading System (ETS)) in February 2005 when Kyoto became operative. The three Scandinavian EU members had two methods in place during the 2005–08 period to encourage GHG reduction: taxing and trading. Norway, not in the EU, used just taxes. The other EU members, including Spain, applied just the carbon trading ETS scheme to encourage compliance with the Kyoto Protocol. The fundamental issue addressed is this one: Did publicly held firms headquartered in Spain adequately report participation in the EU carbon emissions trading mechanism? Data to answer this question were obtained from the 2011 and 2012 annual reports for domestic Spanish public companies that received tradable emissions permits. In addition to assessing investor-owned firms’ disclosure posture, the specific method of reporting about carbon emissions permits, whether companies used, banked, or sold the permits granted by the government, also is reviewed. This empirical research effort reports on a complete survey of all available data for the two financial reporting periods that concluded the second phase of the Kyoto Protocol.     

Optimal intensity targets for greenhouse gas emissions trading under uncertainty

Uncertainty is an obstacle for commitments under cap and trade schemes for emission permits. We assess how well intensity targets, where each country’s permit allocation is indexed to its future realized GDP, can cope with uncertainties in international greenhouse emissions trading. We present some empirical foundations for intensity targets and derive a simple rule for the optimal degree of indexation to GDP. Using an 18-region simulation model of a cooperative, global cap-and-trade treaty in 2020 under multiple uncertainties and endogenous commitments, we show that optimal intensity targets could reduce the cost of uncertainty and achieve significant increases in global abatement. The optimal degree of indexation to GDP would vary greatly between countries, including super-indexation in some advanced countries, and partial indexation for most developing countries. Standard intensity targets (with one-to-one indexation) would also improve the overall outcome, but to a lesser degree and not in all individual cases. Although target indexation is no magic wand for a future global climate treaty, gains from reduced cost uncertainty and the potential for more stringent environmental commitments could justify the increased complexity and other potential downsides of intensity targets.      

CUTTING CARBON EMISSIONS AT A PROFIT (PART I): OPPORTUNITIES FOR THE UNITED STATES

This article identifies and corrects shortcomings in recent modeling studies on the economics of reducing greenhouse gas emissions in the United States. The major assessments of the Kyoto Protocol—by the U.S. Energy Information Administration, the Clinton White House Council of Economic Advisers, the U.S. Department of Energy Interlaboratory Working Group, and the Stanford Energy Modeling Forum—are found to be seriously incomplete. Each study omits one or several of four major cost-reducing policy options, resulting in cost estimates that are far too pessimistic.
In the present study, these shortcomings are overcome through the integrated evaluation of all major cost-cutting policy options within a coherent least-cost framework. Three domestic policies—a national carbon cap and permit trading program, productivity-enhancing market reforms and technology programs, and recycling of permit auction revenues into economically advantageous tax cuts—are combined with international emissions allowance trading.
This analysis shows that an integrated least-cost strategy for mitigating U.S. greenhouse gas emissions would produce an annual net output gain of roughly 0.4% of GDP in 2010 and about 0.9% of GDP in 2020. On a cumulative net present value basis, the United States would gain $250 billion by 2010 and $600 billion by 2020. International flexibility mechanisms (including emissions trading) are of only secondary significance in realizing these productivity, output, and welfare gains.     

Strategic partitioning of emission allowances under the EU Emission Trading Scheme

The EU Emission Trading Scheme (ETS) is breaking new ground in the experience with emission trading regimes across multiple jurisdictions. Since the EU ETS covers only some industries, it implies a hybrid emission control scheme where EU member states must apply complementary domestic emissions regulation for the non-trading sectors of their economies in order to comply with their national emission reduction targets. The EU ETS thus opens up for strategic partitioning of national emissions budgets by the member states between trading and non-trading sectors. In this paper we examine the potential effects of such strategic behavior on compliance cost and emissions prices. We show that concerns on efficiency losses from strategic partitioning are misplaced. In turn, our analysis implicitly indicates significant political economy forces behind EU climate policy, as both cost-effective and strategically motivated partitioning of national emission budgets are far off from the actual break-down between trading and non-trading sectors.     

The Strategic and Effective Dimensions of the Border Tax Adjustment

Between 2001 and 2011, the Kyoto Protocol has experienced defections of two countries that took part in its negotiation and accounted for around 44% of all parties' emissions. The border tax adjustment, a tax levied on imports to reproduce domestic taxation on similar goods, is advocated to prevent such compliance failures as well as to support unilateral pollution regulations by mitigating firms' competitiveness losses and carbon leakages. The paper investigates whether this trade instrument can constitute a decentralized solution to achieve the first‐best in a noncooperative framework. It develops a two‐country two‐firm reciprocal‐market model of trade with global pollution and country heterogeneity. Countries' interactions are studied following a noncooperative game theory approach, for two scenarios defined by the possibility to implement a border tax adjustment to sanction unilateral deviation from the cooperative situation. The paper predicts first that this opportunity modifies the countries' choices of strategies toward more compliance; second that among the strategic and effective dimensions of the border tax adjustment, only the former allows to achieve the first‐best; finally that the border tax adjustment fosters countries' participation in the cooperative international environmental agreement.

Emissions Trading and Profitability: The Swedish Pulp and Paper Industry

The purpose of this paper is to develop models with and without potential emissions trading and to compare industry profits under the two regimes. The model in which emissions trading is permitted is a nonparametric industry frontier model in the spirit of Färe et al. (1992). It is relative to this model that industry profit is computed. This profit is compared to the profit without emissions trading to give an estimate of the potential gains that can be realised by allowing for emissions trading. The model, which is applied to data for the Swedish pulp and paper industry, suggests that this industry would have had up to 6% (1%) higher profits in 1989 (1990) if emissions trading had been used instead of individual permits to achieve the same total emissions target. Currently there is no permit trading in this industry so our results only model the potential gains that can be made.     

New directions in emissions trading: the potential contribution of new institutional economics

Once an arcane topic even among environmental economists, emissions trading systems have substantially increased during this past decade in the USA. Moreover, the implementation of these systems has necessitated increased involvement of professionals in many fields besides economics. This paper reviews the practical experience of the six major types of emissions trading systems, focusing on credit market development, participation and results, including transaction costs. Five more recent applications of emissions trading also are considered, as well as the possibility of inter-pollutant trading. While inter-pollutant trading has been successfully used for chlorofluorocarbons (CFCs), the applicability of this experience is probably very limited. Additionally, it would be highly premature to attempt an evaluation of these newer emissions trading systems, some of which have yet to be even partially implemented. In order to improve these latter and future programs, the paper considers the potential contribution of the New Institutional Economics (NIE) to emissions trading. The NIE is used to develop theoretical insights and a series of predictions about the performance of a range of emissions trading systems.

Origins and Development of the EU ETS

The successful creation of the European Union Emissions Trading Scheme (EU ETS) was not inevitable. Countries such as Canada and Japan which might be thought to have a less complex and more cohesive cultural and institutional context failed to do so. Europe succeeded for a number of reasons: with a Single Market for the economy, the logic of a single market for environment is inexorable; the European Commission—which had failed in its earlier efforts to introduce a carbon energy tax—made the case for trading with great skill and persistence, on the basis of qualified majority voting, which meant no country had a veto; the UK and Denmark initiated their own national schemes, and there was a serious risk of balkanising the market with up to 27 different schemes, with the losses of scale and scope this would entail; meeting the Union’s Kyoto commitments required a substantive pan European response, and EU ETS was the most credible and effective way of doing so. The European Parliament and Environmental Non Governmental Organisations played a constructive role, pushing for more auctioning of allowances and less of them, allocated centrally. Free allocation managed by Member States (MS) was a necessary condition to achieve the support needed, so they failed to achieve these objectives in the initial phase, but they characterize the Commission’s proposals post 2012.     

An empirical analysis of air pollution emissions policy for the U.K. residential sector

In this paper an analysis of the U.K. government's air pollution emissions policy for the residential sector is undertaken. The analysis covers emissions arising from water and space heating, electric appliances and cooking appliances. Using an integrated economic-engineering model, the effects of the Energy Savings Trust and the imposition of Value Added Tax on residential fuel will be evaluated in terms of energy consumption and pollution emissions. It is found that the initial proposed policy was not sufficiently stringent to meet the government's environmental objectives, and that subsequent events have undermined the government's programme even further. Unless alternative policies are introduced, emissions from the residential sector will play an important role in jeopardizing the ability of the U.K. government to meet its international obligations.     

Economic Implications of Alternative Allocation Schemes for Emission Allowances*

For reasons of political feasibility, emission trading systems may have to rely on free initial allocation of emission allowances in order to ameliorate adverse production and employment effects in dirty industries. Against the background of an emerging European‐wide emission trading system, we examine the trade‐off between such compensation and economic efficiency under output‐based and emissions‐based allocation rules. We show that the emissions‐based allocation rule is more costly than the output‐based rule in terms of maintaining output and employment in energy‐intensive industries. When the international allowance price increases, the inferiority of emissions‐based allocation vis‐à‐vis output‐based allocation becomes more pronounced, as emission subsidies drastically restrict efficiency gains from international trade in emission allowances.     

Alternative standards and instruments for air pollution control in Poland

Like other Central European countries, Poland faces the twin challenges of improving environmental quality while also fostering sustainable economic development. In this study we examine the costs of different standards for air pollution control, and the cost savings from using incentive-based policy instruments in lieu of more rigid command-and-control policies. The comparisons are based on the results of a simulation model of energy use and air pollution control for the Polish economy over 1990–2015. The model simulates least-cost energy supply decisions under different environmental policy assumptions, the corresponding emissions, and the cost of achieving the specified policy objectives. The model results suggest that incentive-based policies will have efficiency gains over command policies that are at least worthy of consideration and may be quite substantial. The size of the gains in practice depends in part on how much flexibility is built into the command approach, e.g., capacity for intrafirm trading as well as alack of technology-specific requirements. To achieve these gains, an increase in the current levels of emissions fees is desirable both to strengthen abatement incentives and to improve the capacity of the Polish government to overcome past environmental damages. However, it seems highly unlikely in practice that fees could be raised to the levels necessary to meet current Polish emissions standards. To make further headway, an evolutionary approach to emissions trading patterned after (and profiting from the experience with) emissions trading in the U.S. seems useful. The program could start out relatively modestly and increase in ambitiousness as the Polish economic transition proceeds.     

Designing environmental policy: lessons from the regulation of mercury emissions

In its waning days, the Clinton administration decided that it was appropriate to regulate mercury emissions from power plants. The incoming Bush administration had to decide how best to regulate these emissions. The Bush administration offered two approaches for regulating mercury emissions from power plants. The first was to establish uniform emission rates across utilities, as mandated by the 1990 Amendments. The second was to establish a cap on mercury emissions while allowing emissions trading in order to reduce the cost of achieving the goal. This paper presents the first cost-benefit analysis of this issue that takes account of IQ benefits. We find that the benefits of the mercury regulation are likely to fall short of the cost. This assessment is based on a number of assumptions that are highly uncertain. The finding of negative net benefits is robust to many, though not all, reasonable variations in the model assumptions. We also find that the emissions trading proposal is roughly $15 billion less expensive than the command-and-control proposal.

Marginal abatement cost curves in general equilibrium: The influence of world energy prices

Marginal abatement cost curves (MACCs) are a favorite instrument to analyze international emissions trading. This paper focuses on the question of how to define MACCs in a general equilibrium context where the global abatement level influences energy prices and in turn national MACCs. We discuss the mechanisms theoretically and then use the CGE model DART for quantitative simulations. The result is, that changes in energy prices resulting from different global abatement levels do indeed affect national MACCs. Also, we compare different possibilities of defining MACCs—of which some are robust against changes in energy prices while others vary considerably.
