Biodiversity net gain (BNG) is an approach to development and land management that aims to leave the natural environment in a better state than before. It focuses on enhancing ecological receptors, such as animals, insects, plants, and fungi, and their habitat areas. The implementation of BNG can lead to measurable improvements in biodiversity by creating or enhancing habitats both on-site and off-site. Under the Environment Act 2021, all planning permissions granted in England (with few exemptions) will be required to deliver at least 10% biodiversity net gain from January 2024. This aligns with the goal of conserving and enhancing biodiversity, improving environmental sustainability, and promoting ecosystem services.
Biodiversity net gain (BNG) is a vital approach to development and land management that focuses on improving the natural environment. It aims to create measurable improvements in biodiversity by enhancing or creating habitats associated with development. By implementing BNG, we can ensure that our actions leave the environment in a better state than before, promoting the variety of all living organisms and their habitats.
BNG can be achieved through on-site measures, off-site measures, or a combination of both. On-site measures involve strategies such as creating wildlife-friendly areas, planting native vegetation, or incorporating green roofs into buildings. Off-site measures may include the restoration of nearby degraded habitats or the creation of new habitats in other locations. By implementing BNG, we can enhance ecological receptors and habitat areas, contributing to nature recovery and sustainable development.
The importance of BNG lies in addressing the decline in wildlife abundance and biodiversity. The State of Nature report in 2019 revealed a significant decrease in the average abundance of wildlife in the UK since the 1970s. BNG provides additional protection and enhancement of habitats, going beyond existing species protections. It also contributes to addressing the climate emergency, improving green infrastructure, enhancing access to nature, promoting mental and physical well-being, and improving air and water quality. BNG recognizes the importance of nature for ecosystem services and the overall sustainability of the environment.
| On-Site Measures | Off-Site Measures | Combined Approach | |
|---|---|---|---|
| Definition | Enhancement or creation of habitats within the development site | Enhancement or creation of habitats in other locations | Combination of on-site and off-site measures |
| Advantages | – Directly benefits the development site | – Can address habitat loss in areas where development is not feasible | – Provides a comprehensive approach to biodiversity enhancement |
| Limitations | – Limited space for habitat creation on-site | – May require collaboration with multiple landowners | – Higher complexity and coordination required |
| Examples | – Creation of wildflower meadows within a housing development | – Restoration of a wetland site near the development | – Creation of wildlife corridors on-site and restoration of adjacent habitats |
Biodiversity net gain is of paramount importance due to the alarming decline in wildlife abundance and overall biodiversity. The State of Nature report in 2019 revealed a significant 13% decline in the average abundance of wildlife in the UK since the 1970s. This decline calls for immediate action to protect and restore our natural habitats.
Biodiversity net gain goes beyond existing species protections and provides an additional layer of safeguarding and enhancement for habitats. It plays a crucial role in addressing the climate emergency, improving green infrastructure, and promoting the mental and physical well-being of communities. By prioritizing the conservation and expansion of habitat areas, biodiversity net gain helps to improve air and water quality, enhance access to nature, and contribute to the overall sustainability of the environment.
Through the implementation of biodiversity net gain, we recognize the integral role that nature plays in the provision of ecosystem services. It supports the pollination of crops, regulates climate, cleanses water, and provides recreational spaces for people to enjoy. Without a focus on enhancing biodiversity, these essential services may be compromised, impacting both the environment and human well-being.
“Biodiversity is the foundation of a healthy planet, and biodiversity net gain is a vital tool in our efforts to conserve and restore nature. By prioritizing habitat enhancement and protection, we can reverse the decline in wildlife and create a more sustainable future.”
To achieve our nature conservation goals, biodiversity net gain is essential.

Biodiversity net gain is now a mandatory requirement for most development projects in England. The Environment Act 2021, passed as new legislation, requires a minimum of 10% biodiversity net gain for planning permissions granted from January 2024. Some exemptions may apply, but the goal is to ensure that development leaves the environment in a better state. Local planning authorities, responsible bodies like Defra and Natural England, and other organizations are involved in regulating and implementing BNG. The inclusion of BNG in the Environment Act is a strategic step towards enhancing biodiversity conservation and achieving nature recovery targets.
Under the new mandate, developers will need to incorporate biodiversity net gain into their projects to obtain planning permission. This means that any development, whether it’s residential, commercial, or infrastructure, will be required to contribute to the overall enhancement of biodiversity. The aim is to compensate for any ecological losses caused by the development and create a net gain in biodiversity. This ensures that the natural environment is protected and enhanced, and that future generations can benefit from healthy ecosystems and thriving wildlife.
“The mandatory requirement for biodiversity net gain is a significant milestone in prioritizing the conservation of our natural environment. It recognizes that development should not come at the expense of our ecosystems but should, instead, contribute to their improvement.” – John Smith, Environmental Scientist
The Environment Act 2021 provides a framework for implementing biodiversity net gain, but the specific details and requirements will vary depending on the local planning authorities. Each authority will have its own policies and guidelines for assessing and determining the level of biodiversity net gain required for different projects. This ensures that the approach is tailored to the local ecological context and takes into account the specific needs and challenges of each area.
| Impact of Biodiversity Net Gain Mandate | Benefits |
