FSR Talk with Grischa Perino organised by FSR Climate 

In this online talk, we will look at the upcoming reform of the European Union Emissions Trading Scheme (EU ETS), particularly the Market Stability Reserve (MSR) Review, with Grischa Perino from the University of Hamburg.

The EU ETS is the cornerstone of the European climate policy covering about 45% of the EU’s greenhouse gas emissions. It follows the polluter pays principle under a cap-and-trade mechanism, whereby firms covered by the ETS purchase, sell and exchange emissions allowances representing one tonne of CO2-eq.

Within this carbon market, the Market Stability Reserve has the objective to increase resilience to demand shocks, deliver investment signals, and raise synergies with other climate and energy policies. It consists of a rule-based mechanism that adjusts the number of allowances to be auctioned to the market surplus by controlling the number of allowances in circulation in the carbon market. The surplus of allowances determines the response of the MSR:

  • If the surplus exceeds a certain threshold, a predetermined percentage of the surplus is withheld from auctions and added to the reserve;
  • if the surplus is lower than another threshold, some allowances are taken from the reserve and injected into the market through auction.

The European Commission’s proposal for MSR Review is planned for June 2021, in the context of a broader reform of the EU ETS to include new sectors in its scope and to support the new EU pledge to reach climate neutrality by 2050. In the publication discussed during this talk, the authors argue that a new MSR design appears necessary. They identify the risks that arise from the current MSR design and propose a feasible way to address them in the upcoming review of the EU ETS.

In this event hosted by Jean-Michel GlachantSimone Borghesi will discuss with Grischa Perino and Jos Delbeke the MSR and the main findings of the paper.
