It is critical that the 2030 ESD delivers real-world GHG reductions of at least 30%. However, it is equally important to transform the current ESD into an instrument that is “Paris proof”.

This briefing discusses five new ideas to improve ESD governance. It builds on a new report by Ecologic and the various experiences in EU member states but also on existing EU legislation and practice.
