Goods imported into the UK from countries with a lower or no carbon price will face a levy by 2027.

On 18 December 2023, the UK government announced a proposal for a new carbon border adjustment mechanism (UK CBAM). The announcement follows extensive consultation earlier this year on possible measures to mitigate carbon leakage risks and aims to support the UK’s decarbonisation efforts.

The UK has made a number of decarbonisation commitments including reaching net zero by 2050. These commitments to decarbonise can be undermined by “carbon leakage”, in which production of goods and associated emissions move from a jurisdiction with more ambitious climate policies (which add costs to carbon-intensive processes) to another jurisdiction with less ambitious policies, resulting in an overall negative impact on the carbon intensity of the processes/goods themselves. The UK CBAM (or other form of carbon tax) seeks to address this issue by aiming to put a fair price on the carbon emitted during the production of certain carbon-intensive goods entering the UK.
