Question to the HM Treasury:

To ask the Chancellor of the Exchequer, when she plans to begin a formal assessment of the potential addition of refined petroleum products to the scope of the UK Carbon Border Adjustment Mechanism.

As announced at Budget 2025 the government is considering the feasibility and impacts of including refined products in the Carbon Border Adjustment Mechanism (CBAM) in future. The government recognises that refineries play a role in energy security and the UK’s industrial base. Government Ministers are holding a roundtable with the refining sector on 4 February 2026 and will also publish a call for evidence on the fuel sector shortly.
