Key Components of Mandatory BNG
The implementation of mandatory biodiversity net gain (BNG) involves several key components that are outlined in the Environment Act. These components ensure a standardized approach to achieving net gains in biodiversity and contribute to the overall goal of sustainable development. The key components of mandatory BNG include:
- Biodiversity Metric: The Biodiversity Metric is a habitat-based approach used to calculate the net gain in biodiversity value resulting from a development or changes in land management. It provides a means of assessing the changes in biodiversity value and determining the required net gain in habitat.
- Habitat Securing: Developers are required to secure the habitat created for at least 30 years. This ensures the long-term preservation and enhancement of biodiversity, allowing ecosystems to flourish and support wildlife populations.
- Biodiversity Credits Scheme: The Environment Act allows for the creation of a statutory biodiversity credits scheme. Developers can purchase credits if the required net gains cannot be achieved on-site or through the off-site market. The funds generated from the sale of credits will be invested in habitat creation.
These key components of mandatory BNG work together to ensure that development projects contribute to enhancing the natural environment and leave a positive impact on biodiversity.
Mandatory BNG Components Overview
| Component | Description |
|---|---|
| Biodiversity Metric | A habitat-based approach to measuring biodiversity value. Used to calculate the net gain in habitat resulting from a development or changes in land management. |
| Habitat Securing | Developers must secure the habitat created for a minimum of 30 years to ensure its long-term preservation and enhancement of biodiversity. |
| Biodiversity Credits Scheme | A statutory scheme that allows developers to purchase credits if the required net gains cannot be achieved on-site or through the off-site market. The funds generated from the sale of credits are invested in habitat creation. |
Implementation Timeline for Mandatory BNG
Implementation of the mandatory biodiversity net gain policy is set to take place in a phased approach in England. The majority of development projects will be required to comply with the policy starting from January 2024. However, there will be exemptions and a delayed implementation for small sites, which will come into effect from April 2024. This staggered approach allows developers and local planning authorities more time to adapt and prepare for the policy requirements.
It is important to note that Nationally Significant Infrastructure Projects will have a separate timeline, and they are planned for implementation in 2025. These projects involve large-scale developments with significant environmental implications, and therefore, additional time is allotted to ensure effective biodiversity net gain measures can be implemented.
The implementation timeline for mandatory biodiversity net gain aligns with the government’s commitment to sustainable development and the protection of biodiversity. By setting clear deadlines, the policy aims to ensure that all development projects in England contribute to enhancing the natural environment and leave a positive impact on biodiversity.
| Mandatory BNG | Implementation Date |
|---|---|

| Nationally Significant Infrastructure Projects | 2025 |
By adhering to the implementation timeline, developers and planning authorities can ensure that biodiversity net gains are achieved effectively, contributing to sustainable development and the preservation of biodiversity for future generations.
On-site and Off-site for BNG
In the context of biodiversity net gain, “on-site” refers to all land within the boundary of a project, usually within a red line boundary. This includes the area where the development is taking place and any associated land directly under the control of the development. It encompasses the natural habitat on the project site that may be affected by the development. The on-site area provides an opportunity to implement measures and strategies to enhance biodiversity and mitigate any potential negative impacts.
Conversely, “off-site” refers to all land outside of the on-site boundary, regardless of ownership. This includes adjacent areas, neighboring land, and any other land that is not directly part of the project site. Off-site areas may provide alternative habitats or ecological networks that can support biodiversity and compensate for any loss or degradation caused by the development. Off-site mitigation measures can include the creation or restoration of habitats, such as wetlands or woodlands, in nearby locations.
It’s important to note that the on-site does not include land within the “blue line” boundary. The blue line boundary represents the extent of the development site’s impact on the water environment, such as rivers, lakes, or coastal areas. These areas may have their own regulations and mitigation measures specific to protecting aquatic ecosystems and biodiversity.
Example Table: Comparison of On-site and Off-site Biodiversity Measures
| Aspect | On-site | Off-site |
|---|---|---|
| Habitat Creation | Designing and implementing new habitats within the development site. | Creating habitats in nearby areas to compensate for any loss or degradation on-site. |
| Habitat Restoration | Restoring degraded habitats within the development site to improve biodiversity. | Restoring degraded habitats in neighboring areas to enhance ecological connectivity. |
| Species Enhancement | Implementing measures to support and encourage the presence of specific species on-site. | Supporting the population of specific species in nearby habitats through conservation actions. |
| Ecological Connectivity | Creating and maintaining ecological corridors and networks within the development site. | Establishing ecological linkages between existing habitats to facilitate species movements. |
The table above provides an overview of some of the measures that can be taken for biodiversity net gain on-site and off-site. These measures aim to enhance the natural environment, conserve species, and promote ecological resilience. By combining on-site and off-site actions, development projects can achieve a net gain in biodiversity, leaving the environment in a better state than before.
The Biodiversity Metric
Measuring and assessing biodiversity is essential for understanding the impact of development and land management practices. The Biodiversity Metric, developed by Natural England, provides a habitat-based approach to measuring biodiversity value. It allows for the evaluation of changes in biodiversity value resulting from development or changes in land management.
The Biodiversity Metric 4.0 is the current version used for mandatory biodiversity net gain. It calculates a proxy biodiversity value, which is then used to determine the required net gain in habitat. This metric takes into account factors such as habitat condition, connectivity, and distinctiveness to provide a comprehensive assessment of biodiversity value.
“The Biodiversity Metric is a valuable tool for ensuring that development projects contribute to biodiversity conservation and enhancement,” says [Name], an expert in environmental planning. “By quantifying the biodiversity value of a site and setting targets for net gain, it helps guide decision-making and ensures that development is carried out in a sustainable and ecologically sensitive manner.”
The Biodiversity Metric plays a crucial role in achieving the objectives of the biodiversity net gain policy. It provides a standardized and scientifically robust method for assessing the impact of development on biodiversity and ensures that adequate measures are taken to enhance and protect habitats. By incorporating the Biodiversity Metric into planning and decision-making processes, the UK aims to achieve long-term ecological resilience and safeguard its natural capital for future generations.

Its use in the mandatory biodiversity net gain policy ensures that development projects in the UK contribute to the enhancement and conservation of the natural environment. By accurately measuring and assessing biodiversity value, the Biodiversity Metric helps create a more resilient and ecologically rich landscape for both wildlife and people.
Biodiversity Gain Plan
The biodiversity gain plan is a crucial component of the mandatory biodiversity net gain policy for development projects in the UK. It is a document that outlines how a proposed development will deliver net gains for biodiversity, ensuring that the natural environment is enhanced rather than degraded. The plan is required for approval by the planning authority and should align with the biodiversity gain objective set by the Environment Act.
The biodiversity gain plan covers various aspects related to biodiversity conservation and enhancement. It includes measures to minimize the impacts on habitats, both on-site and off-site, and strategies to restore and create new habitats. The plan also considers the pre-development and post-development biodiversity values, assessing the overall net gain achieved by the proposed development.
Furthermore, the biodiversity gain plan includes an evaluation of the biodiversity value of any off-site habitat provided as compensation for any loss of biodiversity caused by the development. This ensures that the net gain is achieved even if it cannot be fully delivered on-site. The plan should also outline monitoring and management strategies to ensure the long-term success of the biodiversity enhancements.
Overall, the biodiversity gain plan is a comprehensive document that guides developers in implementing biodiversity net gain measures effectively. By considering the development proposals in relation to the existing biodiversity value and setting clear objectives for net gain, the plan plays a crucial role in promoting sustainable development and ensuring the conservation of biodiversity.
| Key Elements of a Biodiversity Gain Plan |
|---|
| – Minimizing impacts on habitats |
| – Restoring and creating new habitats |
| – Assessing pre-development and post-development biodiversity values |
| – Evaluating the biodiversity value of off-site habitat compensation |
| – Monitoring and management strategies |
National Biodiversity Credits Scheme
The National Biodiversity Credits Scheme is a crucial component of the biodiversity net gain policy in the UK. It allows developers to purchase statutory biodiversity credits if they are unable to achieve the required net gains on-site or through the off-site market. This scheme provides an innovative approach to ensuring habitat creation and ecological enhancement in a sustainable manner.
Through the purchase of credits, developers contribute to funding the creation of new habitats, providing valuable resources for wildlife conservation and ecological resilience. The credits are sold by Natural England on behalf of the Secretary of State, and the funds generated from their sale are reinvested in habitat creation initiatives.
This scheme aims to balance the needs of development projects with the goal of biodiversity conservation. By offering developers the opportunity to invest in habitat creation, it ensures that the environmental impacts of development are mitigated and that the natural environment is enhanced. The pricing of the credits is set higher than the equivalent biodiversity gains on the market, encouraging developers to prioritize on-site measures and only utilize the credits as a last resort.
Benefits of the National Biodiversity Credits Scheme
The National Biodiversity Credits Scheme provides several benefits for both developers and the natural environment:
- Flexibility: The scheme offers developers flexibility in meeting their biodiversity net gain requirements, allowing them to utilize off-site options if needed.
- Habitat Creation: The funds generated from credit sales are used to create new habitats, enhancing biodiversity and ecological resilience across the country.
- Sustainable Development: By incorporating biodiversity considerations into development projects, the scheme promotes sustainable development practices that prioritize long-term environmental benefits.
- Conservation Partnerships: The scheme fosters partnerships between developers, conservation organizations, and landowners, facilitating collaboration in achieving biodiversity net gain objectives.
Overall, the National Biodiversity Credits Scheme plays a crucial role in ensuring that development projects contribute to the enhancement of the natural environment.
