To ask the Secretary of State for Environment, Food and Rural Affairs, how he plans to (a) quantify and (b) measure the impact of new developments on biodiversity.

Answer

Mary Creagh

Grants of planning permission for new development, unless exempt, are now subject to biodiversity net gain, requiring developers to achieve a 10% increase in biodiversity compared to the value of the site before the development proposal. Developers must use the statutory biodiversity metric to measure and quantify how they will achieve the 10% net gain.
