Climate-related litigation is increasingly being used as a tool to hold private and public sector actors to account over their contributions to climate change. According to the Grantham Institute’s 2023 Global Trends in Climate Change Litigation Policy Report (the “Report“) – which was published on 29 June 2023 – around two-thirds of climate-related cases have been filed since 2015: between 1986 and 2014, approximately 800 cases were filed, but between 2015 and May 2023, approximately 1,557 cases were filed.
Although the majority of the climate-related cases identified in the Report were brought against regional and national governments, the Report identified an increase in the number of climate-related cases brought against private sector actors. Of the 190 climate-related cases identified in the Report as being filed between June 2022 and May 2023, around 46% were filed against an increasingly diverse pool of private sector actors. This reflects the growing recognition by prospective litigants of litigation as an effective means of influencing the actions private sector actors are taking to address climate change. We discuss the trends identified in the Report in this blog post.
