  • Options for Avoiding Carbon Leakage
    21 Options for avoiding carbon leakage Carolyn Fischer Resources for the Future Carbon leakage – the increase in foreign emissions that results as a consequence of domestic actions to reduce emissions – is of particular concern for countries seeking to put a substantial price on carbon ahead of their trading partners. While energy market reactions to changes in global fossil fuel demand are difficult to avoid, absent a global price on carbon, some options are available to address leakage associated with changes in competitiveness of energy-intensive, trade-exposed industries. This chapter discusses the main legal and economic trade-offs regarding the use of exemptions, output-based rebating, border carbon adjustment, and sectoral agreements. The potential for clean technology policies to address the energy market channel is also considered. Ultimately, unilateral policies have only unilateral options for addressing carbon leakage, resulting in weak carbon prices, a reluctance to go first and, for those willing to forge ahead, an excessive reliance on regulatory options that in the long run are much more costly means of reducing emissions than carbon pricing. Recognising those costs, if enough major economies could agree on a coordinated approach to carbon pricing that spreads coverage broadly enough, carbon leakage would become less important an issue. Furthermore, a multilateral approach to anti-leakage measures can better ensure they are in harmony with other international agreements. If anti-leakage measures can support enough adherence to ambitious emissions reduction programmes, they can contribute to their own obsolescence. 297 Towards a Workable and Effective Climate Regime 1 Introduction Carbon leakage is a chief concern for governments seeking to implement ambitious emissions reduction policies – particularly those that place high prices on carbon – ahead of similar actions on the part of their major trading partners.

Karney NBER Working Paper No. 18898 March 2013 JEL No. Q27,Q28,Q56,Q58 ABSTRACT We extend the model of Fullerton, Karney, and Baylis (2012 working paper) to explore cost-effectiveness of unilateral climate policy in the presence of leakage. We ignore the welfare gain from reducing greenhouse gas emissions and focus on the welfare cost of the emissions tax or permit scheme. Whereas that prior paper solves for changes in emissions quantities and finds that leakage may be negative, we show here that all cases with negative leakage in that model are cases where a unilateral carbon tax results in a welfare loss.

  • Carbon Emission Reduction—Carbon Tax, Carbon Trading, and Carbon Offset
    energies Editorial Carbon Emission Reduction—Carbon Tax, Carbon Trading, and Carbon Offset Wen-Hsien Tsai Department of Business Administration, National Central University, Jhongli, Taoyuan 32001, Taiwan; [email protected]; Tel.: +886-3-426-7247 Received: 29 October 2020; Accepted: 19 November 2020; Published: 23 November 2020 1. Introduction The Paris Agreement was signed by 195 nations in December 2015 to strengthen the global response to the threat of climate change following the 1992 United Nations Framework Convention on Climate Change (UNFCC) and the 1997 Kyoto Protocol. In Article 2 of the Paris Agreement, the increase in the global average temperature is anticipated to be held to well below 2 ◦C above pre-industrial levels, and efforts are being employed to limit the temperature increase to 1.5 ◦C. The United States Environmental Protection Agency (EPA) provides information on emissions of the main greenhouse gases. It shows that about 81% of the totally emitted greenhouse gases were carbon dioxide (CO2), 10% methane, and 7% nitrous oxide in 2018. Therefore, carbon dioxide (CO2) emissions (or carbon emissions) are the most important cause of global warming. The United Nations has made efforts to reduce greenhouse gas emissions or mitigate their effect. In Article 6 of the Paris Agreement, three cooperative approaches that countries can take in attaining the goal of their carbon emission reduction are described, including direct bilateral cooperation, new sustainable development mechanisms, and non-market-based approaches. The World Bank stated that there are some incentives that have been created to encourage carbon emission reduction, such as the removal of fossil fuels subsidies, the introduction of carbon pricing, the increase of energy efficiency standards, and the implementation of auctions for the lowest-cost renewable energy.

Carbon Tariffs: Effects in Settings with Technology Choice and Foreign Production Cost Advantage David F. Drake Harvard Business School, Harvard University, Boston, MA 02163 [email protected] Emissions regulation is a policy mechanism intended to address the threat of climate change. However, the stringency of emissions regulation varies across regions, raising concerns over carbon leakage|an outcome where stringent regulation in one region shifts production to regions with weaker regulation. It is believed that such leakage adversely increases global emissions. It is also believed that leakage can be eliminated by carbon tariffs, which are taxes imposed on imported goods so that they incur the same emissions cost that they would have if they had been produced in the regulated region. Results here contradict these beliefs. This paper demonstrates that carbon leakage can arise despite a carbon tariff but, when it does arise under a carbon tariff, it decreases emissions. Due in part to this clean leakage, results here indicate that a carbon tariff decreases global emissions. Domestic firm profits, on the other hand, can increase, decrease, or remain unchanged due to a carbon tariff, which suggests that carbon tariffs are not inherently protectionist as some argue.

  • EU Emissions Trading System (EU ETS)
    1 | 8 Last Update: 9 August 2021 International Carbon Action Partnership ETS Detailed Information EU Emissions Trading System (EU ETS) General Information Summary Status: ETS in force Jurisdictions: Member states: 27 EU Member States and three European Economic Area- European Free Trade Association (EEA-EFTA) states: Iceland, Liechtenstein and Norway The European Union Emissions Trading System (EU ETS) is a cornerstone of the EU’s policy to combat climate change and a key tool for reducing, on a cost-effective basis, GHG emissions from the regulated sectors. The system covers ~40% of the EU’s emissions, from the power sector, manufacturing industry, and aviation within the European Economic Area. It is the oldest and now second-largest ETS in force. Introduced in 2005 and now in its fourth trading phase, the EU ETS has gone through several reforms. The latest reform of the ETS was proposed in July of 2021 as a part of the European Green Deal. As of January 2020, the EU ETS became linked to the Swiss ETS, the first linking of this kind for both parties. Year in Review In July 2021, the European Commission released the “Fit for 55” package – a sweeping set of policy proposals spanning all major sectors of the economy to achieve emission reductions of at least 55% below 1990 levels. The package places the EU ETS at the heart of the EU’s decarbonization agenda with major changes that include: a one-off reduction to the cap and increased linear reduction factor (from 2.2% to 4.2%); the inclusion of the maritime sector into the EU ETS’ scope

  • Carbon Leakage: an Overview Andrei Marcu, Project Leader Christian Egenhofer Susanna Roth Wijnand Stoefs CEPS Special Report No
    Carbon Leakage: An overview Andrei Marcu, Project Leader Christian Egenhofer Susanna Roth Wijnand Stoefs CEPS Special Report No. 79/December 2013 Abstract Carbon leakage is central to the discussion on climate policy, given the confluence of issues that are currently being debated, including the 2030 Energy and Climate Framework and the review of the EU carbon leakage list by 2014. Carbon leakage is the result of asymmetrical carbon policies, especially carbon pricing, and the resulting carbon cost, which affects the international competitive position of some EU industry and could displace production and/or investment, and the emissions of the activities displaced. This paper identifies the difference between carbon price and carbon cost to leakage- exposed industry as one of two fundamental issues to be understood and addressed; lack of visibility on future climate policies and anti-leakage provisions is the other key issue. While this is a global issue, most of the experience has been accumulated in the EU. Carbon leakage is only one of the factors that could affect the competitive position of sectors, but it is difficult to attribute the impact of carbon costs versus other variables such as energy costs, labour, etc. Studies have predicted the risk of a significant amount of production leakage in a number of energy-intensive industries. To address the danger, they were included in the EU ETS carbon leakage list, which gave them access to free allowances. However, a limited number of studies undertaken after the end of the second trading period (2012) show little evidence of production leakage and asks the question whether the issue has not been blown out of proportion.

  • International Trade and Carbon Leakage
    Working Paper Series Congressional Budget Office Washington, DC International Trade and Carbon Leakage Bruce Arnold Congressional Budget Office [email protected] December 2013 Working Paper 2013-08 To enhance the transparency of the work of the Congressional Budget Office (CBO) and to encourage external review of that work, CBO’s working paper series includes papers that provide technical descriptions of official CBO analyses as well as papers that represent independent research by CBO analysts. Working papers are not subject to CBO’s regular review and editing process. Papers in this series are available at http://go.usa.gov/ULE. The author received helpful comments and suggestions from Terry Dinan, Mark Hadley, and Andrew Stocking of CBO; from Lindsay Coleman, Juann Hung, and Jennifer Smith, formerly of CBO; and from Rob Johansson of the Department of Agriculture (also formerly of CBO) and Richard Morgenstern of Resources for the Future. Kevin Perese of CBO assisted with parts of the analysis. Abstract Under a broad-based carbon tax or cap-and-trade program, some of the reduction in U.S. carbon dioxide emissions would probably be offset by increases in foreign emissions that would not otherwise have occurred, a phenomenon known as carbon leakage. Industries with substantial total emissions, high trade ratios, and high emission intensities are the most likely to generate substantial leakage. Therefore, the industries most likely to be sources of significant leakage through trade in their products are the chemical; primary metal (such as aluminum and iron and steel); and, to a lesser extent, the nonmetallic mineral products (cement, lime, gypsum, and glass) and petroleum and coal products (refining and coke production) industries.

  • Marginal Abatement Cost, Thereby Achieving Cost-Effectiveness in Aggregate
    The Future of US Carbon-Pricing Policy Robert N. Stavins, John F. Kennedy School of Government, Harvard University Executive Summary There is widespread agreement among economists—and a diverse set of other policy analysts—that at least in the long run, an economy-wide carbon-pricing system will be an essential element of any national policy that can achieve mean- ingful reductions of CO2 emissions cost-effectively in the United States. There is less agreement, however, among economists and others in the policy community regarding the choice of specific carbon-pricing policy instrument, with some sup- porting carbon taxes and others favoring cap-and-trade mechanisms. This prompts two important questions: How do the two major approaches to carbon pricing compare on relevant dimensions, including but not limited to efficiency, cost-effectiveness, and distributional equity? And which of the two approaches is more likely to be adopted in the future in the United States? This paper ad- dresses these questions by drawing on both normative and positive theories of policy instrument choice as they apply to US climate change policy and draws extensively on relevant empirical evidence. The paper concludes with a look at the path ahead, including an assessment of how the two carbon-pricing instru- ments can be made more politically acceptable.
