Environmental degradation is escalating rapidly at the national and global level. Environment Protection Department, Punjab was established to combat this problem. Environment Protection Department, Punjab created Environment Protection Agency (EPA) which is responsible for the protection, conservation, rehabilitation and improvement of the environment; the prevention and control of pollution; and promotion of sustainable development in the province.

EPA is building on its successes through reliable and effective legislation about environment protection and high-quality service delivery. EPA sustains qualitative and quantitative standards for the discharge of effluents, wastes, air emissions or noise either for general applicability or for a particular area or from a particular source in the form of Punjab Environmental Quality Standards (PEQS) and other standards established under the laws, rules and regulations.
