In the Budget 2025, on 26 November 2025, the Chancellor of the Exchequer, the Rt Hon Rachel Reeves MP, announced a suite of fiscal and regulatory measures with direct implications for environmental law, environmental governance and the wider regulatory framework under the Environment Act 2021 and Climate Change Act 2008. Although the Budget is framed around economic growth, productivity and infrastructure delivery, a significant number of measures affect environmental taxation, carbon pricing, land remediation, waste and resource efficiency, and the planning regime governing major development.
