Abstract
The Federal Government of Pakistan has legislated on the protection of environment in 1997. After Eighteenth Amendment to the Constitution of Islamic Republic of Pakistan, 1973, the subject of environment devolved to the Provinces, and thereafter, all the Provinces legislated on environmental protection. This article has reviewed through comparison the post Eighteenth Amendment provincial legislation on environment, and has identified strengths and weaknesses of each of such legislation. Mostly, the legislation is the reproduction of the Federal legislation on environmental protection. Comparatively, the Balochistan, the Khyber Pakhtunkhwa and Sindh environmental legislations have incorporated new environmental concepts, while the Punjab legislation is a complete reproduction of the Federal legislation in verbatim. The article has made recommendations related to uniform development of law on the protection of environment in light of the environmental conventions and national policies of the federal government.
