Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment he has made of the potential impact of the Carbon Border Adjustment Mechanism due to come into effect on 1 January 2027 on UK companies that are reliant on imported steel and other carbon-intensive products.

CBAM is expected to have limited impacts on importers and users of CBAM goods, as set out in the tax information and impact note published alongside primary legislation in November 2025. The tax information and impacts note can be found at the following link:
