Free allocation in the European Emissions Trading System (EU ETS): identifying efficient mechanisms by 2030

30 November 2015 - Climate Report

In a world with asymmetrical climate policies, the conclusions of the European Council of October 2014 agreed on continuing the allocation of free CO2 emissions allowances beyond 2020 to industrial sectors in the EU ETS. This statement has been confirmed in the European Commission’s proposal to revise EU ETS directive for phase IV disclosed in July 2015. The stated objective is to ensure that the most efficient industrial installations do not face undue carbon costs which would lead to carbon leakages. Furthermore, free allocations should not undermine the incentive to cut CO2 emissions, lead to distortions or windfall profits and reduce the auctioning share of allowances.

From 2013 to 2020, the allocation of free allowances has been defined according to harmonized European rules based on benchmarks (carbon intensity targets) and historical output adjusted to the free allocation cap by applying the Cross-Sectoral Correction Factor (CSCF). What would be the impact of pursuing the current mechanism through to 2030? Does the EU Commissions’ proposal of 15th July respond to the Council’s requirements? Which alternative mechanisms could do so?
This study examines four scenarios and their potential consequences.

  • Scenario 1 continues the current free allocation mechanism until 2030. The volume of free allocations thus calculated would be higher than the available free allocation cap and would need to be reduced by a Cross-Sectoral Correction Factor (CSCF) of 66% in 2030. Carbon costs would thus increase for all installations, regardless their exposure to carbon leakages, reducing the protection of most exposed sectors, while widely allocating sectors with limited exposure.
  • Scenario 2 analyses the proposal to implement an allocation mechanism based on recent industrial output combined with appropriate updating of benchmarks. This allocation method is more effective in combating carbon leakage, as it gives clearer incentive to maintain domestic production. Besides, it enables to avoid over-allocations and perverse threshold effects observed in Phase III, but it further mutes the carbon price signal to consumers, and should be complemented by additional mechanisms to exploit demand -side abatement potentials. This mechanism would lead to a less impacting CSCF of 71% in 2030 with a 1.4% annual growth assumption that would however depend on the aggregate output level. Based on our estimates, this factor would be comprised between 62% and 82% in 2030, entailing an uncertainty about the net carbon cost borne by installations amounting to 10% of added value for the cement sector and 6% for the steel sector, with a 30€/tCO2 price assumption.
  • In Scenario 3, a more targeted and focused allocation is presented, which better reflects the exposure to carbon leakage risks. It is proposed to use differentiated allocation rates either based on carbon cost and trade intensity thresholds like implemented in California for example, or based on targeted maximum carbon costs for each sectors depending on trade intensity. This would enable to reduce the allocation volume and overcome the ex post correction and the uncertainty coming with it, and to mitigate carbon costs more efficiently for exposed sectors.
  • The Scenario 4 assesses the European Commission’s proposal, which could be leading to a 20% ex post reduction of allocation volume to all installations by 2030, on top of the 20% uniform reduction of benchmarks. Focusing allocation to exposed sectors, and enhancing flexibility in the supply of free allowances through a dynamic New Entrant Reserve could be levers to help combat carbon leakages more efficiently and maintain incentives to reduce emissions.

In the end, it appears that a combination of instruments is needed to forge a credible roadmap for decarbonisation of industry sectors: a predictable carbon price signal, flexible and targeted free allocation, as well as additional instruments to steer demand for low-carbon products and the emergence of innovative production processes.

    Social and Climate Budget Tagging: Insights from Indonesia

    Attention is growing to the need to tackle climate and social issues jointly. Indeed, both climate change and climate policies affect social issues such as poverty, inequality, or access to healthcare. A well-known example is that of carbon pricing, a climate policy which can have regressive effects in some contexts. As another example, climate change induced heatwaves are disproportionately likely to impact poorer individuals who typically have more constrained access to healthcare, physical jobs in outdoor conditions, and through indirectly driving up food prices. To foster an effective and sustainable transition to low-carbon and resilient economies, policymakers need to ensure individuals do not lose more from climate policies than they already lose from the effects of climate change, but instead benefit from them.

    After Bonn and towards COP 29: the battle on finance and the role of financing plans for the transition

    Tense climate negotiations just ended in Bonn with limited progress on finance and the revised climate commitments under the Paris Agreement. During the opening ceremony of the sixtieth sessions of the subsidiary bodies (SB 60) of the United Nations Framework Convention on Climate Change (UNFCCC), Simon Stiell –Executive Secretary– highlighted the need to “make serious progress on finance, the great enabler of climate action” and to aim for bolder, broader and inclusive third generation Nationally Determined Contributions (NDCs 3.0) that “can serve as blueprints to propel economies and societies forward and drive more resilience”.

    Carbon pricing revenues: their role in financing the climate transition

    Last month, the Executive Secretary of the UNFCCC, Simon Stiell, stressed how important this and next year are for the achievement of the Paris Agreement and called for “a quantum leap in climate finance” ahead of the Spring Meetings of the World Bank Group and International Monetary Fund. Indeed, with emissions required to peak before 2025, our window of opportunity is rapidly closing to keep 1.5°C within reach. More and better finance is urgently needed. Carbon pricing policies and their revenues are part of the tools available that can help fill the climate finance gap.
