Updated: Mar 14, 2021


The environment protection law was enacted in 1986 and it is applicable to the whole of India, including the state of Jammu and Kashmir. It was called umbrella legislation. It fills the gaps in the earlier laws regarding the protection of environment law. It was the Bhopal gas tragedy which necessitated the government of India to make an advanced law on environmental legislation including rules regarding handling and storing and use of hazardous waste. On the basis of these rules, the parliament enacted the environment protection act, 1986. The objective of this act is to protect and improve the environment. Under this act, the ministry of Environment and Forest (MOEF) was assigned the overall responsibilities for administering the laws and policies in India.

Article 51(A) (g) of the Indian Constitution states that it shall be the duty of every citizen to improve and protect the natural environment including forest, lakes, rives and wildlife. It is the fundamental duty of each and every citizen to improve and protect the natural assets such as gas, iron, air, water, wood, oil, coal and wind energy.

In case of Mc Mehta v/s Union of India (1998) 6 SCC 63, the Supreme Court of India held that under article 51(a) g of the Indian constitution, it is the duty of the central government to launch compulsory teaching for 1 hr in a week on environment protection to all the educational institution.

Public Interest Litigation would be maintainable before the High Court under Article 226 and before the Supreme Court under article 32 pertaining to matters of environment protection.
