Over the past two decades a global jurisprudential trend of domestic climate litigation against governments and companies has emerged. One avenue for litigation against these entities is tort law. The tort of negligence could provide access to compensation for aggrieved individuals and groups. Using the example of Australia, this article discusses whether the emergence of climate tort cases, an increasing drive to hold corporations responsible for climate change, and a company focus on voluntary climate action, could lead to the emergence of a new duty of care by corporate actors toward non-shareholders. We highlight opportunities and barriers to the further development of negligence law as a cause of action against corporations for harms related to climate change.
