The implementation of mandatory biodiversity net gain in the UK is governed by the Environment Act, which amends the Town & Country Planning Act to require a minimum 10% net gain in biodiversity value for development projects. This significant step aims to ensure that development activities contribute to the enhancement of the natural environment. To achieve this, several key components have been introduced.
The Biodiversity Metric is a tool used to calculate and measure changes in biodiversity value resulting from development or changes in land management. It assigns a value to different habitats based on their distinctiveness, condition, and strategic significance. Developers are required to use this metric to assess the pre-development and post-development biodiversity value of their sites, ensuring a net gain of at least 10%.
Habitat security is a crucial aspect of biodiversity net gain. Developers must secure habitats for a minimum of 30 years through planning obligations or conservation covenants. This ensures the long-term protection and preservation of habitats, allowing for the establishment of sustainable ecosystems and the promotion of biodiversity.
In cases where achieving net gain on-site or through off-site measures is challenging, a new statutory biodiversity credits scheme has been introduced. Developers can purchase biodiversity credits from the government to compensate for the net gain shortfall. These credits are then used to invest in habitat creation activities, ensuring that the overall net gain target is met. A national register for net gain delivery sites will be established to monitor and track the implementation and progress of biodiversity net gain.
| Component | Description |
|---|---|
| Biodiversity Metric and Calculation | A tool used to measure changes in biodiversity value resulting from development or land management. It assigns a value to different habitats based on distinctiveness, condition, and significance. |

The implementation of biodiversity net gain will ensure that development projects leave the natural environment in a better state for future generations, contributing to the preservation and enhancement of the UK’s biodiversity.
Biodiversity net gain can be achieved both on-site and off-site, depending on the planning context and project requirements. In the planning context, on-site refers to all land within the boundary of a project, usually indicated by a red line boundary. Off-site, on the other hand, refers to all land outside of the on-site boundary, regardless of ownership. It’s important to note that the blue line boundary, which is often used to define protected areas, does not fall within the definition of on-site.
One way to achieve on-site biodiversity net gain is by incorporating biodiversity enhancements within the project design. This can include measures such as creating green roofs, installing bird nesting boxes, or planting native vegetation. By integrating these enhancements directly into the development, the project can contribute to increasing biodiversity value within its immediate surroundings.
Off-site biodiversity net gain, on the other hand, involves creating or enhancing habitats in nearby locations outside of the project’s boundary. This can be done through initiatives like establishing wildlife corridors, restoring degraded ecosystems, or creating new habitats in collaboration with local conservation organizations. Off-site net gain provides opportunities to improve biodiversity value in areas that may have suffered habitat loss or degradation due to previous development or land management.
To achieve a successful biodiversity net gain, a combination of on-site and off-site measures can provide the most effective and comprehensive approach. By considering both the immediate project area and its wider surroundings, developers and land managers can contribute to the preservation and enhancement of biodiversity, supporting a sustainable and resilient natural environment.
| On-Site Biodiversity Net Gain | Off-Site Biodiversity Net Gain |
|---|---|
| Enhancements integrated into the design | Creation or restoration of habitats outside of the project boundary |
| Directly benefits the project area | Improves biodiversity value in nearby locations |
| Visual enhancements, such as green roofs or landscaped areas | Supports habitat connectivity and ecological resilience |
By implementing a combination of on-site and off-site biodiversity net gain strategies, developers and land managers can play a vital role in conserving and enhancing the natural environment, creating a more sustainable and resilient future for all.
The Biodiversity Metric plays a crucial role in measuring biodiversity value and assessing changes in biodiversity resulting from development or land management. It takes a habitat-based approach, assigning a value to habitats based on factors such as distinctiveness, condition, and strategic significance. By using this metric, developers can determine the proxy biodiversity value of an area before and after a development project, allowing them to track biodiversity gains.
The latest version of the Biodiversity Metric is Biodiversity Metric 4.0, developed by Natural England. This version will serve as the basis for the statutory metric laid before Parliament in November 2023. It provides developers and planning authorities with a standardized tool to evaluate and monitor biodiversity net gain. By utilizing the Biodiversity Metric, stakeholders can ensure that their efforts contribute to achieving the mandatory net gain target of at least 10%.
The Biodiversity Metric enables a comprehensive assessment of biodiversity value, allowing for informed decision-making during the planning and implementation phases of development projects. It provides a quantitative measure that allows stakeholders to evaluate the effectiveness of their biodiversity enhancement efforts. By tracking changes in biodiversity value over time, developers can ensure that their projects result in a genuine net gain in biodiversity.
In conclusion, the Biodiversity Metric is a vital tool in the implementation of biodiversity net gain. It facilitates the measurement of biodiversity value and enables developers and planning authorities to assess the effectiveness of habitat creation, restoration, and enhancement measures. By using the Biodiversity Metric, stakeholders can contribute to the preservation and enhancement of biodiversity, ensuring the long-term sustainability of our natural environment.
A biodiversity gain plan is a crucial document in the context of mandatory biodiversity net gain. It outlines the strategies and actions that a development project will undertake to achieve a net gain in biodiversity value. The plan plays a vital role in minimizing the development impact on habitats and assessing the pre- and post-development biodiversity values of the site. By incorporating measures for on-site and off-site habitat creation, restoration, or enhancement, the biodiversity gain plan aims to enhance the overall biodiversity objectives of the project.
The development impact on biodiversity is a concern that needs to be addressed through ecological mitigation measures. The biodiversity gain plan provides a framework for developers to identify and implement suitable mitigation strategies to minimize any adverse effects on habitats and species. By following the statutory requirements for biodiversity net gain, developers can ensure that their projects contribute positively to the preservation and enhancement of biodiversity.
“The biodiversity gain plan demonstrates how adverse impacts on habitats have been minimized, assesses the pre-development and post-development biodiversity values of the site, and includes measures to enhance biodiversity through on-site or off-site habitat creation.”
The biodiversity gain plan is a key requirement for obtaining planning permission. Planning authorities evaluate the biodiversity gain plan to ensure that the proposed development aligns with the mandatory biodiversity net gain principles. By submitting a robust and well-designed biodiversity gain plan, developers increase their chances of obtaining planning permission while contributing to the long-term conservation and enhancement of biodiversity.
| Biodiversity Gain Plan Components | Importance |
|---|---|
| Assessment of pre- and post-development biodiversity values | Provides a baseline for measuring net gain |
| Identification of adverse impacts and mitigation measures | Minimizes development impact on habitats and species |
| Inclusion of on-site and off-site habitat creation, restoration, or enhancement | Achieves net gain in biodiversity value |
| Alignment with statutory requirements and planning policies | Ensures compliance and increases the chances of obtaining planning permission |
The National Biodiversity Credits Scheme is a statutory scheme established under the Environment Act, allowing the UK government to sell biodiversity credits to developers to meet the required biodiversity net gains. This scheme provides a mechanism for developers to contribute to habitat creation and enhancement when it is not feasible to achieve the necessary net gains on-site or through off-site measures.
The sale of biodiversity credits involves assigning a monetary value to biodiversity enhancements that surpass the minimum net gain requirements. The credits are priced higher than equivalent biodiversity gains on the market, encouraging developers to prioritize on-site biodiversity improvements. The revenue generated from the sale of statutory biodiversity credits will be invested in habitat creation and restoration projects to contribute to the overall net gain of biodiversity in the UK.
The National Biodiversity Credits Scheme is managed by the UK government and implemented through Natural England, which oversees the sales process. Defra has published indicative credit prices, providing developers with an understanding of the cost associated with purchasing credits. To facilitate the sale of credits, a digital sales platform is being developed and tested.
| Biodiversity Credits Scheme | Benefits |
|---|---|
| 1. Habitat Creation | Contributes to the creation of new habitats and ecological corridors. |
| 2. Biodiversity Value | Increases the overall biodiversity value, supporting the conservation of species and habitats. |
| 3. Statutory Compliance | Enables developers to meet the mandatory net gain requirements when on-site or off-site measures are not feasible. |
| 4. Funding Conservation | Generates revenue to invest in habitat creation and restoration projects. |
The National Biodiversity Credits Scheme provides a flexible and practical solution for achieving biodiversity net gains in situations where on-site measures are limited. By incorporating this scheme into the mandatory requirements, developers can contribute to the enhancement and preservation of the UK’s biodiversity, ensuring a sustainable future for the natural environment.
As biodiversity net gain becomes mandatory in the UK, certain exemptions and definitions are included in the legislation to provide clarity and address specific circumstances. One notable exemption is for irreplaceable habitats, which may be exempted from the mandatory biodiversity net gain requirement. Irreplaceable habitats are those that are deemed to be of significant ecological importance and cannot be adequately replicated or compensated for elsewhere.
The Environment Act recognizes the need for clear definitions of irreplaceable habitats and lists of habitat types that will be considered as such. The government will consult on the definition and proposed list of irreplaceable habitats to ensure that the exemptions are applied appropriately and consistently across different development projects.
It’s important to note that marine development is excluded from the biodiversity net gain requirement due to the less developed approach and metric for assessing marine habitats and environments. This recognizes the unique challenges and complexities associated with protecting and enhancing biodiversity in marine ecosystems.
Further details and guidance on exemptions and definitions will be provided through secondary legislation, which will offer more specific instructions and considerations for developers and planning authorities to follow in implementing biodiversity net gain.
| Exemption | Definition |
|---|---|
| Irreplaceable habitats | Habitats of significant ecological importance that cannot be adequately replicated or compensated for elsewhere |
| Marine development | Excluded from the biodiversity net gain requirement due to the less developed approach and metric for marine habitats and environments |
