The UK’s national standards body has published a set of requirements for the implementation of Biodiversity Net Gain (BNG) in development projects, including individual house-builds, largescale developments and estate management.

BSI explained that the loss of biodiversity as a result of human activity is having increasingly severe impacts. As a result, governments, businesses and organisations of all types are acting, not only to protect biodiversity, but to ensure it thrives.

BNG is an approach to development and land management that leaves biodiversity in a measurably better state than before.

The new British Standard, BS 8683:2021 Process for Designing and Implementing Biodiversity Net Gain. Specification builds on and adds to the UK’s Good Practice Principles of BNG2. It translates these principles and actions into a specification standard, providing a consistent and structured process for designing and implementing BNG based on good practice.

The Standard has been developed by a committee made up of experts in the fields of sustainable development, construction, local government and land and water management.

The Head of Environment, Social and Governance Standards at BSI, David Fatscher, said: “To achieve BNG, a project needs to follow the mitigation hierarchy and be able to demonstrate that it has followed the UK’s Good Practice Principles of BNG in order to leave the biodiversity of the affected area in a measurably better state than before”.

It has, he went on, an important role to play in protecting, restoring and recovering nature and supporting thriving ecosystems.
