Question to the Department for Transport:

To ask His Majesty's Government whether the amount of litter discarded by the side of motorways and major roads in Britain has increased or decreased in the last 12 months.

National Highways reported that over 2021/22, 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, per the Code of practice on litter and refuse. This is the most recent data available. Data for 2022/23 will be reported to the Department for Transport and the Office of Rail and Road, and published in annual reports to Parliament, this summer.
