The KfW/ZEW CO2-Barometer – developed as part of a cooperative project of KfW Bankengruppe and the Centre of European Economic Research (ZEW) – has been analyzing the situation of German companies regulated under the European Union Emissions Trading System (EU ETS) on an annual basis since 2009. The study’s objective is to closely monitor firm behavior in carbon markets in order to regularly provide detailed information to policy-makers, businesses and the research community. For that purpose, all German firms regulated under the EU ETS, are invited to participate in the survey every year. On average, approximately 140 companies have responded to the questionnaire per year. The results are reported in an annual publication, the KfW/ZEW CO2-Barometer – Carbon Edition. As a complementary study, KfW Bankengruppe and the ZEW have developed a second annual survey in the framework of the KfW/ZEW CO2-Barometer: the KfW/ZEW CO2-Barometer – Manufacturing Industry Edition. The aim is to shed light on recent developments in the German manufacturing industry driven by European climate and energy regulations as well as the German energy transition in particular.
