About the database
For the legal information & privacy policy, please visit newclimate.org.

The Climate Policy Database, maintained by NewClimate Institute with support from Wageningen University and PBL Netherlands Environmental Assessment Agency, aims to gather information on climate mitigation policies and benchmark these against a policy matrix, that represents a comprehensive policy package to mitigate the effects of climate change. The database covers national mitigation-related policies and is updated periodically. Planned policies are excluded from the database, with an exception of energy and emission targets announced as Intended Nationally Determined Contributions (INDCs) for the post-2020 period.

We aim to establish an open, collaborative platform to gather information on climate-related policies, with full geographical and sectoral coverage. Therefore, we highly welcome your comments for continuous improvement and collaboration at: climatepolicydatabase@newclimate.org.

This project is funded by the European Union H2020 project ELEVATE and was, in the previous phases, funded by CD-Links and ENGAGE.

Versions and API

The Climate Policy Database is updated periodically. The latest version of the database can be downloaded here or accessed through a Python API. The database can also be found here on Zenodo.  

Each year we create a static database for version control:

Version 2023: Contains policies adopted as of the end of 2023. Policy coverage varies across countries but is comprehensive for 42 economies.

Version 2022: Contains policies adopted as of the end of 2022. Policy coverage varies across countries but is comprehensive for 42 economies.

Version 2021: Contains policies adopted as of 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.

Please note that the Climate Policy Database is not exhaustive. For example, the policy coverage and depth of information for each policy is unequal across countries analysed. Policies adopted at subnational level are not comprehensively covered. Please also note that this database is not reviewed by national government officials. Even if covering all policies to their full extent was impossible, the database provides insights about policy trends over time and supports claims about policy adoption.
