Local planning authorities and planning applicants across England have been required to assess the Biodiversity Net Gain of projects since early in 2024.

These measures are a significant change in how planners and landowners consider development and many RTPI members have been concerned about that planning services have not been given sufficient guidance, advice and support and lack the staff and skills to avoid disruption to an already stretched planning system.

This page explains how planners can help to support the implementation of Biodiversity Net Gain.

Case studies

The RTPI are asking planners to come forward and share what works in BNG implementation.

Some councils already applied biodiversity net gain requirements in their planning policies and have already developed best practice. However, in other areas the requirement is entirely new.

RTPI members across the public and private sectors have been calling for stronger guidance and case studies to help them incorporate this new aspect of planning into their practice.

Professionals in the development sector and local authorities can help other planners by sending examples of good practice to us at [email protected] or your Regional Coordinator.

BNG Transition, Implementation and Monitoring Survey

The RTPI is asking members to share their experiences of what is and isn’t working with Biodiversity Net Gain requirements using our on-going survey.

We’re keeping a close eye on Biodiversity Net Gain’s impacts on England’s planning system. The feedback we’ve heard so far about the implementation of this new system has already helped us to shape the Government’s thinking.

The survey is designed to help us understand the profession’s level of knowledge, confidence and priorities for Biodiversity Net Gain implementation over time.

Our findings were published in September 2023 and February 2024.
