A leaked draft declaration for the November 20 EU-UK summit in Brussels reportedly proposes exempting British goods from the EU Carbon Border Adjustment Mechanism, retroactive to January 1, 2026. The proposal has not yet become law and depends on linking the EU and UK emissions trading systems.
Why it matters
The exemption would let UK-origin goods avoid the EU carbon levy that began operating on January 1, 2026, altering costs for importers and exporters on both sides. It also tests how the two countries will align their carbon pricing systems after Brexit.
The leaked draft proposes retroactive relief from January 1, 2026, the start date of the EU's definitive CBAM regime. Article 2(6) of the CBAM Regulation requires a fully linked ETS agreement and an effective carbon price before any third country qualifies, and it is unclear whether that condition will be met.
The players
European Union
The political and economic union of 27 European member states that administers the Carbon Border Adjustment Mechanism and the EU Emissions Trading System.
United Kingdom
The sovereign state comprising England, Scotland, Wales and Northern Ireland, which operates its own emissions trading system and is preparing a separate carbon border levy.
The details
The draft was obtained ahead of the November 20 summit in Brussels. Both sides agreed in May 2025 to pursue a formal ETS link with mutual CBAM exemptions, and the European Council authorised linkage negotiations in November 2025. The UK government has confirmed negotiations are underway.
Timeline
May 2025: EU and UK commit to pursuing ETS linkage in a Common Understanding.
November 2025: European Council authorises ETS linkage negotiations.
January 1, 2026: EU definitive CBAM regime begins; proposed 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 Dynamics
The proposal follows the EU's decision to apply CBAM to imports from January 1, 2026, and tests whether carbon-market linkage can serve as a route around the levy for trading partners. It sits within a broader pattern of major economies designing border carbon measures that interact with their trade relationships.
If finalized, the exemption would lower the carbon-levy cost for UK-origin goods entering the EU, which could affect pricing and margins for importers and exporters. Companies trading across the border may need to track whether qualifying conditions are met before adjusting contracts or pricing.
The takeaway
Businesses trading between the EU and UK should monitor the November 20 summit outcome and the status of ETS linkage negotiations before assuming any CBAM exemption applies. The retroactive start date means the outcome could affect shipments already made since January 1, 2026.
What happens next
The EU-UK summit in Brussels on November 20 will review the draft declaration, and the UK's own CBAM is scheduled to begin in January 2027.
