To ask the Secretary of State for Housing, Communities and Local Government, what proportion of green belt land is under consideration for development in the most recent period for which figures are available.
Decisions on future development on Green Belt land are made by local planning authorities as part of the local planning process. The requested information is not gathered or held centrally. Any data used as basis for an answer would be unreliable, because at any stage of the Local Plan process a local authority may revise its consideration of how much land, and where, to propose for allocation for future development.
The Department does publish statistics on changes in the amount of Green Belt land in England. These are available at https://www.gov.uk/government/collections/green-belt-statistics.
