Biodiversity Net Gain


The Environment Act introduces a mandatory approach to biodiversity net gain (BNG) that will apply from late 2023. Development will be required to leave biodiversity in a better state than before. The KNP is proposing a county-wide approach to BNG to be adopted by all Kent’s planning authorities, that will deliver good outcomes for both nature and communities, as well as providing consistency for developers.

Viability Assessment of Biodiversity Net Gain in Kent – June 2022

In response to the KNP’s promotion of a 20% BNG target for the county, Kent County Council (with funding support from Natural England) commissioned this strategic viability assessment of BNG in Kent. The purpose is to assist the county’s planning authorities to understand whether targeting a higher BNG than the statutory minimum of 10% is potentially viable in the county.  Link below.
