What makes climate policy reliably effective
Assessing the effectiveness of climate policy measures is becoming increasingly difficult as countries continuously expand their climate policies and increasingly complex policy mixes emerge. Today, individual instruments hardly seem isolated, but embedded in dense constellations of parallel measures. In the study "Effective climate policies for 'all seasons': novel evidence from 40 countries", scientists from Spain, Switzerland, Germany and Norway develop a methodological approach that can nevertheless be used to identify robust effects of individual climate policies. On the basis of a comparative analysis of several countries, sectors and policy areas, those measures are determined that reliably contribute to the reduction of CO₂ emissions, regardless of the specific policy mix. The study was published in "Climate Policy".
