England is launching a biodiversity credit scheme this week that attempts to force all new road and housebuilding projects to benefit nature, rather than damage it.

The “nature market”, called biodiversity net gain (BNG), means all new building projects must achieve a 10% net gain in biodiversity or habitat. If a woodland is destroyed by a road, for example, another needs to be recreated. This can happen either on site or elsewhere.

The requirement becomes law under the Town and Country Planning Act on 12 February for larger sites, and on 2 April 2024 for smaller sites.
