Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government whether they have received any advice from the Climate Change Committee regarding making the United Kingdom's nationally determined contribution binding in law; and, if so, what was that advice.

The UK’s Climate Change Committee (CCC) has no statutory responsibilities in relation to the NDC. However, to benefit from its independent expertise, the Secretary of State wrote to the CCC to request guidance on the UK’s 2035 nationally determined contribution (NDC). The CCC's guidance was published in October 2024 and included the recommendation that the UK’s NDC commit to a reduction in territorial greenhouse emissions of 81% from 1990 to 2035. The CCC advised that this target would be consistent with the emissions reductions required to meet the UK’s legally binding Sixth Carbon Budget (2033-2037). This guidance did not include any advice on making the 2035 NDC binding in law.
