The UK Climate Change Act, first passed in 2008 and amended in 2019, is the UK's framework law for the transition to a low-carbon economy, creating an obligation for the government to set legally-binding carbon budgets to act as stepping stones towards an overall 2050 emissions reduction target.

Carbon Budget and Growth Delivery Plan

Published

In 2023, the plan set out sectoral policies and proposals for decarbonising all sectors of the UK economy to meet the net zero target by 2050 and to achieve the emissions reductions required by the sixth carbon budget in particular. It replaced the Net Zero Strategy, which was successfully challenged before the courts for being insufficiently detailed. It was created pursuant to Section 14 of the Climate Change Act. The Plan It was revised in 2025.
The new plan is the government’s roadmap for meeting its legally binding carbon budgets and net-zero target while supporting economic growth, energy security, and job creation. Published under the Climate Change Act, the plan sets out policies and proposals across the economy (energy, transport, buildings, industry, agriculture, waste, and land use) to deliver emissions reductions through 2037. It emphasizes clean energy deployment, electrification, energy efficiency, low-carbon technologies, and investment in green industries, while positioning the net-zero transition as a driver of productivity, investment, and long-term economic competitiveness. The plan also demonstrates how the UK intends to meet its Fourth, Fifth, and Sixth Carbon Budgets (2033-2037) and align domestic climate action with its international climate commitments.
