This project is funded by the European Union H2020 ELEVATE and ENGAGE projects and was, in its previous phase, funded under CD-Links. The database is maintained by NewClimate Institute with support from PBL Netherlands Environmental Assessment Agency and Wageningen University and Research. Although the CPDB exists since 2016, annual versions of the database have only been stored since 2019. The Climate Policy Database is updated periodically. The latest version of the database can be downloaded on the CPDB website or accessed through a Python API. Each year, we also create a static database, which is included here for version control.
