Climate Change Laws of the World: every country's climate rulebook

Climate Change Laws of the World is a free database of national climate laws, policies and related litigation, maintained by the Grantham Research Institute at the London School of Economics together with the Sabin Center for Climate Change Law at Columbia. It covers climate and climate-related laws, including those on energy, transport, land use and resilience. The companion litigation database was built with a gap you should know about: it did not include the United States, which has its own Sabin Center collection. The project's own description is the best place to check the current number of countries covered, because it has grown over the years.
