Public Law & Legal Theory
Litigation over the effects of climate change has taken various forms, of which litigation based on international human rights law is perhaps the most ambitious. Plaintiffs argue that major emitters of greenhouse gases have violated rights to life and health by contributing to environmental and health injuries associated with global warming. International human rights litigation in international tribunals is unlikely to have any effect, but conceivably American courts might be open to these arguments in Alien Tort Statute litigation. If so, this would be a mistake. Because the health of the global climate is a public good, because American courts have limited ability to control the behavior of corporations on foreign territory, and because optimal climate policy varies greatly across countries, it is unlikely that American courts can provide remedies that are economically sound and politically acceptable.
