A U.K. government spokesperson said: “We are working together with the EU to implement the package agreed at the U.K.-EU Summit. We will only agree deals that provide value to the U.K. and U.K. industry.”

Adam Berman, director of policy and advocacy at Energy UK, said it was now “not realistic” that a linkage negotiation would be completed by the end of the year.

This will be “problematic” for British firms, Berman said, which will suddenly be subject to the new tax from Jan. 1, with the energy sector likely to be hit the hardest. But it could also harm the EU, which could see emissions increase as it seeks to replace relatively “cleaner” U.K. imports.

Another headache for both sides is the fact the new regime will apply in Northern Ireland, which has no hard border with the EU, meaning the region could become a backdoor into the EU market for high-carbon goods.
