International Environmental Law

"International environmental law is the set of agreements and principles that reflect the world's collective effort to manage our transition to the Anthropocene by resolving our most serious environmental problems, including climate change, ozone depletion and mass extinction of wildlife. More generally, international environmental law aims to achieve sustainable development—i.e., development that allows people to have a high quality of life today without sacrificing the quality of life of future generations. International environmental law is thus critical both for addressing specific environmental threats and for integrating long-term environmental protection into the global economy."
