Advancing the climate regime through linking domestic emission trading systems?

More and more countries are incorporating the instrument of emissions trading into their national climate policies. This emerging mosaic of emissions trading schemes (ETS) raises the question of whether they should be linked with each other. From an economic point of view, linking of domestic schemes is supposed to increase the economic efficiency of carbon markets. In addition, linking is also expected by some to yield substantial political benefits in terms of the evolution of the UNFCCC/Kyoto regime. However, these optimistic prospects are based on a best-case scenario where all major countries establish environmentally effective emissions trading systems and then link them with each other. Real-life politics might develop rather differently. This paper therefore examines to what extent the current status of emissions trading in industrialised countries provides a basis for reinforcing and moving forward the international climate regime through linking domestic ETS. After comparing emerging emissions trading schemes from an institutional perspective, it emerges that not only emissions trading is at a very early stage in most countries, in addition the emerging systems are probably going to be designed very differently from the EU ETS. While for some design features such as the coverage design differences do not matter, there are some areas where the plans in many non-EU countries look crucially different from the EU system. The outlook for a linked international ETS is therefore currently still very uncertain. Given this state of affairs, the EU should pro-actively engage with the non-EU countries to try to harmonise their developing national emissions trading schemes with the EU ETS, widely disseminate the lessons it has learned from the EU ETS, strongly make the case for environmental integrity and at the same time make clear that systems that want to link to the EU ETS will need to meet certain quality criteria.

Fairness aspects of linking the European emissions trading scheme under a long-term stabilization scenario for CO2 concentration

Climate equity is a crucial but difficult element in negotiations on a post-2012 climate regime. With respect to the trading of greenhouse gas emissions the equity aspect is considered in the Kyoto Protocol which demands that emissions trading should be supplemental to domestic abatement efforts. The question arises whether a linking of the European Union Emissions Trading Scheme (EU ETS) to non-EU emission trading schemes or the Clean Development Mechanism (CDM) could have an impact on principles of climate justice and thus potentially affect ongoing negotiations. In this study, we present the results of a three step analysis: In a first step, it estimates mid-term greenhouse gas emission entitlements for Annex B and Non-Annex B countries for the year 2020 which keep within reach a stabilization of the CO₂ concentration at 450 ppmv in the long-term. In the second step, the resulting emission entitlements are used as an input to an economic partial-equilibrium model in order to assess the shift of abatement efforts under different scenarios of linking the EU ETS. In a third step, we analyze the outcome of the economic model with respect to the future trend of European per capita emissions under the current EU ETS relative to different scenarios of linking the EU ETS. The model results indicate that European per capita emissions have to be reduced to a considerably smaller extent if a linking of the EU ETS is accompanied by an optimal design of the National Allocation Plans and if low-cost CO₂ permits became available via the CDM to a large extent.

The globalization of the carbon market: Welfare and competitiveness effects of linking emissions trading schemes

In the light of the prevailing goal to keep global temperature increase below 2° and recent challenges to reach a global climate agreement in the near term, linking emissions trading schemes has emerged as a prominent complementing policy option. To this end, we explicitly assess (1) the macroeconomic welfare impacts and (2) the trade-based competitiveness effects of linking the European Union (EU) Emissions Trading Scheme in the year 2020. A stylized partial market analysis suggests that, independently of regional cost characteristics, the integration of emissions trading schemes (ETS) yields economic welfare gains for all participating regions. A computable general equilibrium analysis confirms these findings at the macroeconomic level: The economic efficiency losses from emissions regulation are diminished for both EU Member States and non-EU regions by linking ETS. However, the quantitative analysis suggests opposite trade-based incentives for linking up: while EU Member States improve their terms of trade by integrating with emerging ETS, non-EU linking candidates face competitiveness losses by linking. We conclude that, for non-EU regions, the attractiveness of linking ETS is a matter of priorities for economic welfare or international competitiveness. If these priorities are hierarchized in favor of welfare, the globalization of the carbon market could become a promising policy option complementing the efforts to reach a global climate agreement in 2015.     

A taxonomy for regulatory uncertainty—application to the European Emission Trading Scheme

Research on environmental uncertainty typically distinguishes between different sources of uncertainty according to the different environments that a company interacts with. The regulatory environment and associated uncertainties become especially important when investigating the subject of pollution reduction. Many researchers have started to investigate the effects of environmental regulation on innovation, however, only little is known about the role of regulatory uncertainty in this context. We provide a taxonomy of regulatory uncertainties by building on the Miles and Snow scale of environmental uncertainty. We apply this taxonomy to uncertainties in current climate policy and test it based on a survey among companies that are subject to the European Emission Trading Scheme (EU ETS), a flexible mechanism of the Kyoto-Protocol. Our results show that the EU ETS creates uncertainties in all categories of our taxonomy and suggest further research to better understand how different regulatory uncertainties affect companies’ business decisions.     

CO2-emission reduction costs for petroleum refineries in Sweden

Possibilities to reduce CO₂ emissions and related costs at Swedish petroleum refineries have been estimated. An evaluation of the direct impact on costs for emission-reducing measures due to the inclusion in the EU ETS is also made. Abatement measures possible to implement within the next 5–6 years at Shell refinery Gothenburg corresponding to a 8% reduction, and at Preemraff Lysekil corresponding to 22% of the estimated fossil CO₂ emissions in 2010 have been included. Many of the estimated abatement costs are negative, meaning cost savings for the companies if implemented. The cost estimates are strongly linked to the fuel prices. The inclusion of industries in the EU ETS increases the incentives for companies to implement CO₂ abatement measures.

White certificates and domestic offset schemes: possible synergies

Next to energy efficiency, in the context of GHG reductions, additional policy mechanisms to the incumbent EU Emissions Trading scheme (EU ETS) are discussed. Such is the case of Non-ETS Domestic Offset (DO) schemes, which can reduce CO₂-eq.emissions in the non-ETS sectors and trade these as CO₂ credits on the ETS market. Taking into account that the EU’s “Linking Directive” (EC 2004) creates the conditions to use credits generated by emission reduction projects certified by the UN Framework Convention on Climate Change Kyoto Protocol (KP) within the EU ETS market, in this paper we employ the institutional analysis method of interactions in order to provide insight of a combined White Certificates (WhC) and DOs cheme. Special attention is paid to the parameters that seem to hamper harmonization of WhC and DO. Aim of this paper is to discuss whether smart market- based instruments, such as WhC, can be complementary to the effectiveness of mechanisms fostering energy efficiency such as DOs projects and vice versa. In this respect, the potential combined scheme is assessed (ex-ante) with the help of standard criteria that refer to the triptych energy, environment & society. Given the outcome of the study made, it is fair to say that such a DO/WhC combined scheme could be selected if the additionality concern is to minimize short term social costs of reaching a certain goal. However recent information and research conducted so far cannot yet uphold an ambition that a WhC/DO scheme of this kind could also drive technical change, keep consumer costs down and be equitable.     

CO2 emission reduction costs for iron ore-based steelmaking in Sweden

Possibilities to reduce CO₂ emissions and related costs at Swedish iron-ore based steelmaking in Sweden have been estimated. An evaluation of the direct impact on costs for emission-reducing measures due to the inclusion in the EU ETS is also made.Two different abatement options, based on previously implemented measures at SSAB Oxelösund as well as some future measures that could be implemented at the company by 2010, have been investigated. The first option corresponds to a CO₂ emission reduction of 6.5% and the second to a 13% reduction. The abatement measure with the largest reduction potential is dependent on natural gas being available at SSAB Oxelösund by 2010, which is not certain.Several of the estimated abatement costs are negative, meaning cost savings for the company if implemented. The cost estimates are strongly linked to the fuel prices. The inclusion of industries in the EU ETS increases the incentives for companies to implement CO₂ abatement measures.     

Foresty offsets in emissions trading systems: a link between systems?

An important aspect in the linking of different emissions trading schemes is the degree to which these systems allow (or ban) external offset project categories. The EU Emission Trading Scheme (EU ETS) currently allows the use of credits from energy and industry projects developed under the Kyoto Protocol’s Joint Implementation (JI) and Clean Development Mechanism (CDM) but excludes the use of carbon credits from forestry projects for compliance in the EU ETS. Forestry credits generated by the CDM have a limited lifetime and expire at the end of a project’s crediting period, or earlier if the carbon stock for which the credits have been issued ceases to exist. According to the recently adopted amendment of the EU ETS Directive forestry credits will remain to be excluded until 2020. The present article reviews how the New South Wales Greenhouse Gas Abatement Scheme (Australia), the Regional Greenhouse Gas Initiative (US) and the voluntary scheme of the Chicago Climate Exchange integrate forestry offsets into the respective system and how they deal with the risk of losing stored and credited biomass. By comparing the results of different scenarios this article shows how differences in the treatment of forestry offsets could impact the efforts to link various emission trading systems in future.
