Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of the European Commission’s proposals for the EU Carbon Border Adjustment Mechanism on the competitiveness and decarbonisation of the UK oil refining sector.

At present, the EU Carbon Border Adjustment Mechanism does not include refined oil products .

In December 2025 the European Commission published further detail on their future plans for the CBAM, including the possibility of including refined products in scope at a future date. The UK Government committed in November 2025 to considering the feasibility and impacts of including refined products in the UK CBAM in future.

We continue to monitor the progress of the EU CBAM closely and encourage the EU to continue to engage with affected businesses to minimise the impact on trade, and to recognise and support industries working hard to decarbonise.
