UK-EU ETS Linkage FAQ: What It Means for Carbon Markets and CBAM Costs

The UK and EU have agreed in principle to link their emissions trading systems (ETS), a move that could reduce costs and complexity for businesses on both sides. A new report from the UK Trade and Business Commission warns that without a mutual CBAM exemption, UK firms could face up to £800 million in charges on energy-intensive exports to the EU by 2030. Linking the two ETSs would create the conditions for a reciprocal exemption from each other's carbon border taxes, but the technical details are still being negotiated. The report recommends both sides agree a temporary exemption covering the gap between signing and full implementation to avoid rising costs for UK operators. The agreement would particularly benefit manufacturing regions like Yorkshire, the Midlands, and the North East, and is part of wider energy cooperation talks including UK participation in the EU's internal electricity market.
