EU Draft Would Exempt UK Goods From Carbon Levy
Importers of UK-origin goods into the EU could avoid CBAM costs if the carbon markets are linked, but the exemption is not yet law.

A leaked draft of an EU-UK summit declaration reportedly proposes exempting British goods from the EU's Carbon Border Adjustment Mechanism (CBAM), retroactive to January 1, 2026. The exemption has not become law; it depends on linking the EU and UK carbon markets, so importers of UK-origin goods into the EU should treat it as unconfirmed.
Why it matters
The arrangement would tie CBAM relief to a formal linkage of the EU and UK emissions trading systems, which requires a fully linked ETS agreement and an effective carbon price under Article 2(6) of the CBAM Regulation. Because the EU's definitive CBAM regime began January 1, 2026, the retroactive start date would matter to any UK-origin goods already entering under the levy.
The proposed retroactive exemption would start January 1, 2026, the same day the EU's definitive CBAM regime began operating. The UK plans its own CBAM for January 2027.
The players
European Union
A 27-member trading bloc whose CBAM regulation applies a carbon levy on carbon-intensive imports into the single market.
United Kingdom
A major trading partner whose government is negotiating ETS linkage with the EU and plans its own carbon border mechanism for January 2027.
The details
Under the reported proposal, British goods would avoid the EU carbon levy by linking the two carbon markets, so the EU and UK emissions trading systems would recognize each other. The May 2025 Common Understanding already committed both parties to pursue a formal ETS link with mutual CBAM exemptions. The European Council authorised negotiations on that linkage in November 2025, and the UK government has confirmed talks are underway.
Timeline
May 2025: EU-UK Common Understanding commits to pursuing ETS linkage.
November 2025: European Council authorises ETS linkage negotiations.
January 1, 2026: EU definitive CBAM regime begins; proposed retroactive exemption start date.
November 20, 2026: EU-UK summit in Brussels reviews the draft declaration.
January 2027: UK's own CBAM scheduled to begin.
Market Landscape
Article 2(6) of the EU CBAM Regulation conditions exemption on a fully linked ETS agreement and an effective carbon price in the third country. The reported EU-UK draft would test that condition by linking two carbon markets to grant mutual relief.
Importers of UK-origin goods into the EU should track whether the exemption is adopted and whether it applies retroactively from January 1, 2026. Finance and compliance teams should review CBAM exposure on goods already entering under the levy and consult qualified trade counsel before changing any sourcing or customs decisions.
The takeaway
The retroactive exemption is still a leaked proposal, so importers should not assume relief until the summit outcome and any EU legislative changes are confirmed. Operators with UK-origin inputs should log CBAM costs paid from January 2026 so they can claim refunds if the exemption is adopted.
What happens next
The EU-UK summit in Brussels on November 20 is set to review the draft declaration and address ETS linkage, with the UK's own CBAM scheduled to begin in January 2027.
