This website provides two databases of climate change litigation, one for U.S. climate change litigation and one for non-U.S. cases.
The U.S. Climate Change Litigation database is a joint project of the Sabin Center for Climate Change Law at Columbia Law School and Arnold & Porter Kaye Scholer LLP. It tracks developments in litigation and administrative proceedings related to climate change. Michael B. Gerrard, then a partner at Arnold & Porter LLP and now Faculty Director of the Sabin Center, and J. Cullen Howe, an environmental law specialist at Arnold & Porter LLP, created the U.S. Climate Litigation Chart in 2007. The U.S. chart is updated on a monthly basis, and currently includes 746 cases* with links to 2346 case documents.
The Non-U.S. Climate Litigation Chart was created in 2011 and is updated regularly. It currently includes 251 cases, with links to 222 case documents.
You can view past monthly updates here.

The Sabin Center and Arnold & Porter Kaye Scholer LLP are also grateful to Rachel Bercovitz, Michael Choi, Shaun Field, Patrick Kelly, Kai Salem, and other staff at Columbia Law School and Arnold & Porter Kaye Scholer LLP for their assistance with the transition to the new website.
* The term “cases” in the U.S. chart comprises more than judicial and quasi-judicial administrative actions and proceedings. Other types of “cases” contained in the chart include rulemaking petitions, requests for reconsideration of regulations, notices of intent to sue (in situations where lawsuits were not subsequently filed), and subpoenas. In addition, one case may involve multiple complaints or petitions that have been consolidated, and the entry for a single case may include multiple decisions at the trial and appellate levels.
