To ask the Chancellor of the exchequer, what assessment she has made of the potential impact of the inclusion of refined products in the carbon border adjustment mechanism on national security.
Dan Tomlinson
The Exchequer Secretary
The government recognises the role that refineries play in energy security and the UK’s industrial base. The Government published a call for evidence (https://www.gov.uk/government/calls-for-evidence/future-of-the-uk-downstream-oil-sector/future-of-the-uk-downstream-oil-sector-call-for-evidence) on the future of the fuel sector on 23rd February 2026 in order to help understand the current state of the refining sector.
Following a strategic and technical assessment by HMG, it has been decided not to expand the Carbon Border Adjustment Mechanism (CBAM) to refined oil products in January 2028. Assessing the case for and feasibility of including refined oil products within the Carbon Border Adjustment Mechanism at a later date is a priority. We are continuing to work with the sector to assess the options.

The chancellor is the most senior figure at the Treasury, even though the prime minister holds an additional title of 'First Lord of the Treasury'. He normally resides at Number 11 Downing Street.
