Question to the Department for Transport:

To ask the Secretary of State for Transport, how many trees have been planted by Highways England in each year between 2014 and 2024; and what the cost to the public purse was of this work.

National Highways (NH) does not keep a central record of the number of trees they have planted across England in any given year. However, as outlined in their ‘Net zero highways: our 2030 / 2040 / 2050 plan’, NH aims to plant at least 3 million trees by 2030 (in addition to the trees planted as ‘essential mitigation’ for projects).
