Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government, further to the Written Answer by Lord Hunt of Kings Heath on 24 December 2024 (HL3494), what assessment they have made of the alignment between the United Kingdom’s Nationally Determined Contribution for 2030, which requires that emissions do not exceed around 260 million tonnes of carbon dioxide equivalent, and the existing legally binding framework set by the fifth carbon budget, which limits emissions for the period 2028 to 2032 to around 345 million tonnes of carbon dioxide equivalent per year.

The UK’s 2030 nationally determined contribution - to reduce economy-wide greenhouse gas emissions by at least 68% on 1990 levels – represents an increase in ambition on the UK’s fifth carbon budget, which covers the period 2028-2032. The UK will need to overachieve on the fifth carbon budget to meet the 2030 NDC and stay on track for the sixth carbon budget. In its advice to Government on the setting of the UK’s sixth carbon budget, the Climate Change Committee advised that it did not consider it necessary for Government to reset existing targets, and instead advised that once the 2030 NDC and sixth carbon budget were set on the path to net zero, that these would provide a clear target for UK emissions reductions.
