Question

how has international law responded to climate change?

Answer 1

In addition, two other international environmental treaties address climate change indirectly. The amended 1987 Montreal Protocol on Substances That Deplete the Ozone Layer legally obliges its parties to phase out chlorofluorocarbons (CFCs) by the year 2000 (fact sheet 224).

Answer 2

The ultimate aim of the UNFCCC is to stabilise greenhouse gas concentrations at a level that prevents dangerous human interference with the climate system.
