This report summarises key trends in climate change legislation and litigation, covering legislative activities in 164 countries. The report also includes analysis of climate change litigation across 25 jurisdictions. While the legislative and executive branches of governments have long been prominent domains for climate change action, the judiciary is beginning to play an increasingly important role in national climate policy.
The information is drawn from two major databases that are maintained jointly by the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science, and the Sabin Center on Climate Change Law at the Columbia Law School. The report was prepared by Michal Nachmany, Sam Fankhauser, Joana Setzer and Alina Averchenkova.
