Question to the Department for Transport:

To ask the Secretary of State for Transport, whether his Department has made an assessment of trends in the level of motorway litter in the last (a) three, (b) six and (c) 12 months.

The second Road Investment Strategy (2020-25) includes a litter performance indicator, in line with the Code of practice on litter and refuse published by Department for Environment, Food and Rural Affairs (DEFRA). National Highways is committed to annually reporting against this performance indicator. In 2021/22 National Highways reported that 60.8% of relevant parts of the Strategic Road Network had no litter, refuse or detritus, or was predominately free of litter, refuse or detritus apart from some small items. The 2022/23 report will be made available to the Department, the Office of Rail and Road, and published in annual reports to Parliament, this summer.
