Biodiversity Net Gain

Sustainable development sits high on the political agenda which makes improving biodiversity a key driver for developers, land owners and local planning authorities alike. Biodiversity Net Gain (BNG) is an approach used to improve a sites biodiversity value. Once applied, on completion, a site will have a positive ecological impact, delivering improvements through habitat creation or enhancement after avoiding or mitigating harm.

What is Biodiversity Net Gain?

Biodiversity Net Gain (BNG) sits within the Environment Bill which is on track to gain royal assent later this year. 

Once in force, the bill will require all development schemes to deliver a mandatory 10% biodiversity net gain to be maintained for a period of at least 30 years. The concept seeks measurable improvements for biodiversity by creating or enhancing habitats in association with development. Development proposals must “leave biodiversity in a better state than before”.

But even in advance of the Act, BNG is being required now by Local Planning Authorities that have the appropriate policy framework in place.

What does BNG mean for developers and land owners?

BNG means, moving forward, developers and land owners will have to ensure their projects deliver biodiversity improvements to meet the required 10% increase.

They are already being asked to determine and evidence a project’s final BNG value using the specified Defra biodiversity metric if they want their plans to move through the planning process swiftly.

Many local planning authorities are already requesting that plans allow for these requirements and, as a result, it is recommended that developers consider how their current projects may be affected by these proposals to prevent costly delays down the line.

How can BNG be delivered

To achieve biodiversity net gain, proposals must follow the ‘mitigation hierarchy’ which compels planning applicants to avoid harm in the first instance, then mitigate or finally compensate for losses on-site, off-site or through a combination of the two solutions. These measures will be required in planning conditions.

Making complex easy - How to tackle the common BNG pitfalls

Our BNG experience has highlighted a number of issues and pitfalls that can pose a real threat to project success. To help avoid costly delays, we've put together a series of short video blogs to address some of the complexities that may arise when applying BNG on site.

How can we help you apply BNG to your project?

We are committed to helping our clients achieve the required biodiversity net gains on their developments. Achieving BNG can seem challenging but our team have extensive experience using the DEFRA metric to quantify biodiversity change and we are on hand to take the complexity out of the process.  

We also deliver free, virtual CPD sessions to help educate and prepare companies for what lies ahead.
