There is currently no international legal framework to address environmental disasters and climate change as drivers of migration. There is also no consensus on what terminology should be used to describe individuals moving due to environmental factors. The 1951 Refugee Convention and 1967 Refugee Protocol, multilateral agreements that define "refugee" and set states' obligations for protection, were not crafted with the environment, climate change, or environmental disasters in mind - and therefore do not mention them as grounds for refugee protection. U.S. refugee policy, codified in the Refugee Act of 1980, is largely based on the framework outlined in these agreements and thus excludes these terms.
