Environmental Law in 2025 : A Comprehensive Guide for AIBE Aspirants

Introduction to Environmental Law

Environmental Law in India is a combination of constitutional provisions, statutory enactments, and judicial pronouncements aimed at protecting the environment. Major environmental laws include:

The Environment (Protection) Act, 1986
The Air (Prevention and Control of Pollution) Act, 1981
