This research focuses on climate claims aimed at ordering governments or companies to reduce their greenhouse gas (GHG) emissions in France, Germany, the Netherlands and Switzerland, until December 2023. Traditionally, tort law aims at obliging a tortfeasor to compensate a victim for the damage he or she has caused. In climate claims, however, the aim is not so much to compensate for past damage as to prevent this damage from worsening, by forcing polluters to reduce their present and future emissions. Moreover, the damage faced by victims is not so much climate change per se as the natural disasters it causes. Furthermore, climate change is the result of the worldwide accumulation of GHG emissions over the past decades. Therefore, climate claims raise a number of issues under tort law, with regard to wrongfulness, damage and causation. It raises the following question: to what extent does climate change litigation affect the features of tort liability, and vice versa?
