Business, human rights and climate change: The gradual expansion of the duty of care

This article investigates how human rights considerations are increasingly shaping tort law by focusing on the gradual expansion of the duty of care in business and human rights cases. For decades, victims have attempted to hold parent companies to account for extraterritorial human rights abuses committed by their foreign subsidiaries. Recently, the Supreme Court ruled that UK courts have jurisdiction over such business and human rights cases. These cases are not only jurisdictional. They also contributed to developing the duty of care case law on parental liability. But how much can human rights considerations stretch the boundaries of tort law? The article analyses the case of climate change litigation to assess whether a further development in tort law jurisprudence would be necessary to hold corporations accountable for their contribution to climate change.
