Is the Climate Change Act legally binding on companies?

The Act’s targets are binding on the UK government, not directly on individual companies. However, the government implements the Act’s goals through sector-specific regulations that do create company-level obligations: SECR, ESOS, the UK ETS, MEES, and more. Companies face these regulations as a direct consequence of the Act.

What are carbon budgets?

Carbon budgets are caps on the total amount of greenhouse gases the UK can emit over five-year periods. They are set by the government on the advice of the Climate Change Committee and are legally binding. The UK has set six carbon budgets so far, creating a declining emissions trajectory towards net zero by 2050.

Climate Change Act 2008

The Climate Change Act 2008 is the UK’s foundational climate legislation, establishing legally binding targets for greenhouse gas emission reductions and creating the framework for UK climate policy.

What is Climate Change Act 2008?

The Climate Change Act 2008 was a world-first piece of legislation that committed the UK to reducing greenhouse gas emissions by at least 80% below 1990 levels by 2050. This target was subsequently strengthened to net zero by 2050 through an amendment in June 2019, making the UK the first major economy to legislate for net zero.

The Act established the Climate Change Committee (CCC) — an independent statutory body that advises the government and monitors progress. It introduced five-yearly carbon budgets that cap the total amount of greenhouse gases the UK can emit over each period. The UK is currently in its sixth carbon budget period (2033–2037), which requires a 78% reduction below 1990 levels.

For businesses, the Climate Change Act is the foundation of all UK climate regulation. SECR, ESOS, the UK ETS, MEES, and the upcoming UK Sustainability Disclosure Standards all derive their mandate from the Act’s framework. Understanding the Act provides context for why these regulations exist and how they will likely tighten over time.

Practical Examples

The UK’s net zero amendment to the Climate Change Act in 2019 increased the long-term target from an 80% reduction to a 100% reduction (net zero) by 2050.

The Sixth Carbon Budget, set on the advice of the Climate Change Committee, requires a 78% reduction by 2035 — bringing forward the UK’s decarbonisation trajectory.

A company references the Climate Change Act’s carbon budgets in its transition plan to demonstrate alignment with the UK’s legally binding emission reduction pathway.
