International Environmental Law ensures environmental sustainability, development and growth by working on issues like controlling pollution, saving natural resources, climate change and biodiversity. Environmental law covers international, national and local prospects in the policies.  United Nations Environmental Programme (UNEP) considers the implementation of international environmental laws as one of its key objectives.

Some of the international environmental policies and treaties include; 1972 UN Convention on the Human Environment, 1992 United Nations Conference on Environment and Development (UNCED), 1997 Kyoto Protocol, 2002 World Earth Summit, United Nations Environment Programme, Convention on Biological Diversity.

The basic environmental laws of Pakistan include Pakistan Environmental Protection Act 1997, which in turn formed the Pakistan Environmental Protection Council (PEPC) in 1997, and under this council Pakistan Environmental Protection Agency (federal agency) was also established following several provincial agencies like Sindh Environmental Act 2014.

In order to ensure application of these laws sector 12 of the 1997 Act states, 'No proponent of a prescribed project shall commence construction or operation unless he has filed the Initial Environmental Examination (IEE), or, where the project is likely to cause adverse environmental effects an Environmental Impact Assessment (EIA), with environmental protection agency. IEA and EIA shall be prepared in the light of guidelines issued by the Federal Environmental Protection Agency.'

Several factors can be highlighted to analyse the impact, application and solution of environmental laws in Pakistan. Air pollution is a major issue in the urban areas of Pakistan. According to a World Bank report, 5 million children have suffered illnesses due to air pollution while causing above 20,000 premature deaths each year. In order to reduce this impact the climate change ministry planted ambient air quality stations (AAQS) in several urban cities like Lahore and Islamabad. Followed by initiating air quality surveys in the industrial sectors of the cities, by the Pakistan Environment Protection Agency (Pak-EPA).

In order to follow the international environmental laws, public awareness should be created and spread by the government and environmental authorities. Industries, professionals and general public should be educated about Eco-friendly products and the damage caused by usage and disposal of specific items. Environment protection policies can be practiced with the provision of incentives. Installment of treatment plants, cleaning services and products should be given to industries as preventive measures  to avoid major mishaps or damage to the environment on a broader scale. Those who break the laws and regulations, stated in the environmental policies should be fined and their usual practices should be changed to environment friendly ones.
