The Hague District Court in the Netherlands faced a novel tort law issue in 2021 in Milieudefensie et al v Royal Dutch Shell plc – namely, whether Shell is liable in tort for the reduction costs of carbon dioxide produced in the end use of energy-carrying Shell products. The civil lawsuit aims to make Shell (re)search for adequate substitutes so as to enable Shell’s customers to reduce their consumption of energy-carrying Shell products. It is argued here that Shell’s liability should be assessed within Guido Calabresi’s “cheapest cost avoider” framework.
