India has a long history of environmental protection laws and policies dating back to before independence. Key laws include the Wildlife Protection Act of 1972, the Water and Air Prevention and Control of Pollution Acts of 1974 and 1981, and the Environmental Protection Act of 1986. The Constitution also establishes environmental protection as a duty. Over time, laws have addressed hazardous waste, pollution liability, environmental tribunals, biodiversity protection, and more. Major policies include the National Forest Policy of 1988 and National Environment Policy of 2006. An environmental impact assessment process informs decision making.
