Governance & Policy
UK Environment Act 2021
Definition
The Environment Act 2021 is the UK's overarching environmental governance statute following EU exit. It enables long-term legally binding targets on air quality, water, waste and biodiversity, established the Office for Environmental Protection as a domestic watchdog, introduces biodiversity net gain for development, mandates conservation covenants and requires due diligence on forest-risk commodities.

Comparative context
Overview
What it means
Environmental principles and enforcement that once flowed from EU membership now sit in domestic law with their own institutions.
How it is used
Developers deliver ten percent biodiversity net gain; water companies face storm-overflow duties; regulators and NGOs use OEP complaints to press enforcement.
Why it matters
It defines UK environmental law for a generation and pilots mechanisms — like biodiversity net gain — watched internationally.
