Question to the Department for Transport:

To ask the Secretary of State for Transport, if she will make an estimate of what the level of carbon emissions from National Highways will be in each year between 2025 and 2040.

National Highways set-out its ambitions for putting roads at the heart of Britain’s net zero future within its ‘Net zero highways: our 2030 / 2040 / 2050 plan’ published in 2021. This includes details on emissions reductions goals and the steps that National Highways will take within the period 2025 to 2040. Additionally, the ‘Strategic road network initial report: 2025-2030’, published in 2023, proposes how National Highways in the next five years will specifically support the third road investment strategy (RIS3) development objective of improved environmental outcomes, set out in the ‘Planning Ahead for the Strategic Road Network’ document. The contribution of RIS3 to National Highways’ carbon emissions will be considered as part of the underpinning analysis when RIS3 is set later in 2025.
