The first CECILIA2050 policy brief is now available online. It presents in short the main results of the research that has been conducted so far by the CECILIA2050 project. This includes an evaluation of the current EU climate policies, against a newly developed definition of optimality and the presentation of the results of nine case studies conducted at the EU level as well as at the Member State level. In addition, recommendations for a future climate policy mix are also part of this policy brief.
