It is for the Government to decide whether the currently legislated budgets are amended to bring them in line with the revised 2050 target or the 2030 NDC, but the Committee does not consider it to be necessary. Forthcoming revisions to the UK's emissions inventory will make existing carbon budgets more challenging. The setting of the Sixth Carbon Budget for 2033-37 in accordance with the Committee's advice will also require that the UK cuts emissions in line with the 2030 NDC to remain on track. Once the sixth budget is legislated, the trajectory towards it will have legal force given the requirement in the Climate Change Act that the Government prepare policies to meet the 2050 target and all legislated carbon budgets. Ideally, all future carbon budgets would be aligned with the pathway to achieve Net Zero by 2050. This would fulfil the intention of the Climate Change Act for these nearer-term budgets to ensure that action is on track for the long-term target. report and the UK's NDC for 2030 (implying emissions of 1,585 MtCO₂e, including IAS emissions, over the Fifth Carbon Budget period), as our best indication of what is required to stay on track to our recommended Sixth Carbon Budget and the UK's 2050 Net Zero target.
