Consultation description

We want to know what you think about the implementation of biodiversity net gain (BNG) for nationally significant infrastructure projects (NSIPs). The government is committed to achieving sustainable economic growth to improve the prosperity of our country. The development of high-quality nature-positive infrastructure will support this mission.

BNG is a way of creating and improving natural habitats. BNG makes sure development has a measurably positive impact (‘net gain’) on biodiversity, compared to what was there before development.

We propose introducing BNG for NSIPs from May 2026. This will provide a clear framework to ensure new major infrastructure developments leave biodiversity in a measurably better state than before development took place. This will contribute to our legally binding Environment Act 2021 targets for biodiversity, and provide wider benefits for climate change adaptation and mitigation.

We are also consulting separately on improving the implementation of BNG for minor, medium and brownfield developments.
