Climate Change Laws of the World covers national-level climate change laws, policies, and climate litigation cases globally. It builds on more than decade of data collection by both the Grantham Research Institute at the LSE and the the Sabin Center for Climate Change Law at Columbia Law School. 

The legislation database covers climate and climate-related laws, as well as laws and policies promoting low carbon transitions, which reflects the relevance of climate policy in areas including energy, transport, land use, and climate resilience.
The litigation database climate litigation cases from over 30 countries. These cases raise issues of law or fact regarding the science of climate change and/or climate change mitigation and adaptation policies or efforts before an administrative, judicial or other investigatory body. The dataset does not include the United States – To access information about climate change litigation in the US, please click here to go to the Sabin Center / Arnold & Porter Kaye Scholer database (opens in a new window).

Invitation to contribute

We aim for the datasets to be as comprehensive and accurate as possible. However, there is no claim to have identified every relevant law, policy or court case in the countries covered. We invite anyone to draw our attention to any information we may have missed or any errors or updates to existing data. Please follow this link to contribute. 


Climate Change Laws of the World was redeveloped in 2019 with funding from the LSE’s KEI fund which is designed to support knowledge exchange activities.

We wish to thank the individuals and organisations who have brought our attention to regulatory developments over the years and helped clarify the status of documents - the data is much more complete and accurate thanks to you! 

Apart from the Sabin Center, our highly valued partners on this project also include the Inter-parliamentary Union, the World Resources Institute, and GLOBE International.
