Question to the Department for Transport:

To ask the Secretary of State for Transport, if his Department will make an assessment of the potential merits of a gateway test for carbon emissions to ensure that future transport schemes, with only rare exceptions, contribute to a reduction in emissions as opposed to a negligible or insignificant increase in emissions when compared with the national carbon budget.

Transport schemes are assessed against a wide range of impacts as part of developing business cases. These assessments include carbon and other environmental impacts, and our underpinning models and methodologies are regularly enhanced and updated to take into account the latest data and evidence.
