The Climate Policy Database is updated periodically. We analyse various public sources to compile and categorise climate policies (see Table below). Each year, we create a static database for version control:
Version 2021: Contains policies adopted before the end of 2021. Policy coverage varies across countries but is comprehensive for G20 economies.
Version 2020: Contains policies adopted as of the end of 2020 by the G20 economies and non-comprehensive policy data for remaining countries.
Version 2019: Contains policies adopted as of the end of 2019 by the G20 economies, excluding European Union member states, and non-comprehensive policy data for remaining countries.
Policies are periodically updated. This means that policies adopted before the the latest version of the database can change. For most up to date data, always download the latest version of the database here.
