Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what (a) assessments and (b) controls are in place to ensure the (i) integrity and (ii) effectiveness of measures implemented to achieve biodiversity net gains in development projects.

Biodiversity net gain (BNG) is a mandatory requirement in the planning process, and developments (unless exempt) need to submit information to the relevant local planning authority to demonstrate how they intend to deliver a 10% ‘net gain’ calculated using the statutory BNG metric. This could be through measures taken on-site, off-site or by purchasing government issued credits as a last resort. Any significant on-site (and any off-site) gains must include a legal agreement (covering at least 30 years) and a habitat management and monitoring plan as part of their application.
