🌐 I. Introduction

Air pollution is one of the most severe environmental threats worldwide. It involves the release of harmful substances into the atmosphere, causing adverse health, ecological, and climatic impacts.

Violates statutory provisions under environmental protection laws.

Threatens sustainable development.

In India, prosecution of air pollution as an environmental crime typically involves:

Air (Prevention and Control of Pollution) Act, 1981

Environment (Protection) Act, 1986

Indian Penal Code provisions (for negligence or endangerment, e.g., Sections 268, 269, 270 IPC)
