Carbon Emissions: Taxation

The question

To ask the Chancellor of the Exchequer, when she plans to update Parliament on future expansions of the UK Carbon Border Adjustment Mechanism, including whether refined petroleum products are under consideration for inclusion.

Answered by Dan Tomlinson

For the introduction of Carbon Border Adjustment Mechanism (CBAM) in January 2027, the UK has focused on the sectors most at risk of carbon leakage within scope of the UK ETS, and where it is technically feasible to include products in scope.

As announced at Budget 2025, the government is considering the feasibility and impacts of including refined products in the CBAM in future.

The sectoral scope of the CBAM will be kept under review beyond 2027 as new evidence comes to light to reflect methodological and technological advances.
