The number of climate lawsuits against corporations worldwide has surged, with over 230 cases filed since 2015, mostly after 2020. The US led with 129 cases filed in 2023, followed by the UK with 24. New climate litigation cases emerged in Panama and Portugal in 2023, adding to the 55 countries recording such cases. A growing number of cases were filed in the global south. The rise in climate-washing cases reflects growing scrutiny of environmental claims, which could lead to more honest and effective corporate climate actions.
