This project realized targeted contributions by Ecologic Institute to the "Paris Governance Toolkit" strategy developed by the European Climate Foundation’s Governance Cluster. In this capacity, Ecologic Institute provided input to the strategy as member of a core group of expert advisors to ECF. The project also sought to expand the evidence-base for climate governance effectiveness with a case study analysis of best practices at national and state level around the world, focusing specifically on the design and adoption of climate framework laws. The assessment resulted in a best practice guide for long-term climate governance systems based on a literature review and interviews with relevant experts. The findings of the report were presented at a UNFCCC side event at COP23 in Bonn.
