Consultation on Biodiversity Net Gain Regulations and Implementation

The Government are holding a consultation on Biodiversity Net Gain Regulations and Implementation, that ends on 5th April 2022.  TCAG have responded to the consultation.

That all sounds rather technical and intimidating doesn’t it!?  What exactly does it mean?

Well the new Environment Act which should become mandatory in Nov 2023 aims to make sure new developments better protect and enhance wildlife and nature, will create better places for people to live and work, and ensure we leave our environment in a better state for future generations.

The key points for mandatory Biodiversity Net Gain (BNG) are:

  • Minimum 10% BNG is required – calculated using the current Biodiversity Metric and approval of net gain plan
  • Habitat improvements should be secured for at least 30 years via obligations/ conservation covenant
  • Improvements or enhancements to habitat can be delivered on-site, off-site or via statutory biodiversity credits
  • There will be a national register for net gain delivery sites
  • BNG will also apply to Nationally Significant Infrastructure Projects (NSIPs)
  • BNG does not apply to marine development
  • BNG does not change existing legal environmental and wildlife protections
It’s worth bearing in mind that Biodiversity Net Gain should be in addition to, and not instead of considering and acting to avoid, mitigate, or compensate for biodiversity loss.

More about the consultation
The Department for Environment, Food, and Rural Affairs want to know what we think about how biodiversity net gain will work in practice.  The consultation covers how this is applied to Town and Country Planning Act development, and, at a higher level, Nationally Significant Infrastructure Projects, they’re the big projects like the proposed LTC.
