Environmental governance in Pakistan has gone through several phases of development. Key events include the establishment of the Pakistan Environmental Protection Agency in 1983, the formulation of the National Conservation Strategy in 1992, and the enactment of the Pakistan Environmental Protection Act in 1997. Following the 18th amendment to the constitution in 2010, environmental protection responsibilities were devolved to the provinces, each of which then established their own environmental protection acts after 2011. The timeline outlines the progression of environmental policies, regulations, and institutions over time at both the national and provincial levels in Pakistan.
