Attention is steadily building around the prospect of UK–EU ETS linkage, following recent comments from UK Prime Minister Andy Burnham suggesting that a UK–EU summit could take place in November. While no date has been formally confirmed, the meeting is increasingly viewed as a potential turning point for long‑discussed carbon market integration.

Both sides have already signalled support for linkage in principle. Formal negotiations began in early 2026 but were paused after the UK’s change in government. When talks resume, ETS linkage is expected to sit within a wider package covering energy cooperation, trade, and regulatory alignment, a broader reset of UK–EU climate and market coordination.

For market participants, the focus is less on immediate price impact and more on what linkage would mean for the long‑term relationship between UKAs and EUAs. Expectations are growing that policymakers may aim for a framework capable of delivering linkage by 2028, which would require meaningful clarity during 2027 to support compliance planning and market preparation.

In the meantime, linkage expectations continue to provide underlying support for UKAs relative to EUAs. A linked market would make allowances fungible, removing the structural justification for today’s UKA discount. As a result, many traders see the narrowing UKA–EUA spread as the clearest expression of the linkage theme, and a trend likely to continue if negotiations progress positively.
