Biodiversity net gain

The sky is clear blue and the spires of Lichfield Cathedral are visible above green trees. In the foreground, there are white houses, poppies and green fields.

Biodiversity net gain (BNG) is a new process designed to make sure new developments deliver a net positive impact on the natural environment.

It requires new developments to be designed and planned in ways that minimise any loss and damage to existing habitats and compensate and off-set any damage caused.

Biodiversity net gain is defined as the achievement of measurable gains for biodiversity through new development (e.g. biodiversity is left in a measurably better state than before development began). Biodiversity net gain is important because:

  • the natural environment provides benefits to us all, and is essential for the processes that support life on this planet
  • many habitats are lost or degraded by development, and there are limited measures in place to value, maintain, enhance and create wildlife habitats
  • it delivers measurable improvements for biodiversity by enhancing or creating new habitats in association with development
