We have conducted several studies for DG CLIMA relating to the European Union’s emissions trading system.   For example, we conducted a study looking at the impact of changes in trading activity on the price formation processes in the European carbon market, the access to the market for retail investors, which included also the access via exchange traded funds (ETFs), the hedging strategies of EU emissions trading system (ETS) compliance entities, and the role played by derivatives and financial entities in the EU ETS.
