Governance & Policy
UK Climate Change Act 2008
Definition
The Climate Change Act 2008 is the UK's flagship climate framework law. It set the world's first legally binding long-term emissions target — amended in 2019 to net zero by 2050 — requires five-yearly carbon budgets set well in advance, and established the independent Climate Change Committee to advise government and report on progress to Parliament.

Overview
What it means
UK climate policy runs on a statutory budget-and-scrutiny cycle that binds successive governments regardless of party.
How it is used
Ministers set budgets and respond to CCC progress reports; courts cite the Act in climate plan challenges; other countries copied its architecture.
Why it matters
It is the original national climate framework law — the template for net-zero acts from New Zealand to Canada to Germany.
