How to Ensure Real Estate Developments Comply with Biodiversity Net Gain Requirements?

With the world increasingly focusing on sustainable development, it’s not surprising that the real estate industry is facing new regulations geared towards preserving the environment. The UK government, for instance, has made it a legal requirement for developers to ensure that their projects result in a net gain for biodiversity. This means that any development, be it a residential housing scheme or a commercial complex, should not negatively impact the local habitats and, in fact, should contribute to enhancing them. This article will explore how developers can ensure their projects meet these Biodiversity Net Gain (BNG) requirements.

Decoding BNG and Its Importance

Biodiversity Net Gain is a concept that aims to ensure that development projects leave the biodiversity in a better state than before. In essence, developers must plan their projects in such a way that they lead to a net gain of biodiversity on the project site.

The importance of BNG stems from the alarming rate at which diverse habitats and species are being lost due to human activities, including development. This loss of biodiversity is not only a threat to the environment but also to the socio-economic fabric of our society, as diverse ecosystems provide numerous services such as pollination, soil fertility, and even climate regulation. Thus, BNG is a major step towards sustainable development, compelling developers to integrate environmental considerations into their planning process.

Understanding the Legal Requirements

In order to ensure compliance with BNG, developers need to have a thorough understanding of the legal requirements. The UK government has laid out specific guidelines for developers in its Environment Bill, which states that any new development must achieve a 10% net gain in biodiversity.

To achieve this, developers are required to use the ‘biodiversity metric’, a tool used to assess the biodiversity value of a site before and after development. The metric takes into account various factors such as the type of habitat, its condition, and its importance for biodiversity. If the post-development score is less than the pre-development score, the developer must commit to creating or enhancing habitats elsewhere to achieve the required net gain.

Planning for BNG

Planning for BNG should be an integral part of the project design process. Developers need to collaborate with ecologists, landscape architects, and planners from the very beginning to identify potential impacts on biodiversity and devise strategies to avoid, mitigate, or compensate for them.

One of the key elements of BNG planning is the ‘mitigation hierarchy’, which prioritises avoiding harm to biodiversity wherever possible. If harm cannot be avoided, developers should seek to minimise it through careful design and construction methods. Any residual harm should then be compensated through habitat creation or enhancement.

The planning process should also include regular monitoring and evaluation to ensure that the net gain is being achieved and maintained over the long term.

Engaging with Local Communities

Engaging with local communities is crucial in ensuring the success of a BNG plan. As the people directly affected by the development, local communities can provide valuable insights into the existing biodiversity and how it might be impacted. They can also play a key role in monitoring and maintaining the enhanced habitats.

Developers should therefore seek to involve local communities at all stages of the project, from initial consultation to post-development monitoring. This not only helps to ensure the success of the BNG plan but also fosters positive relationships between developers and the local community, which can be beneficial for the project in the long run.

Working with Environmental Consultants

Given the complexity of BNG requirements, many developers choose to work with environmental consultants who can provide expert advice and guidance throughout the process. These consultants can help developers understand the biodiversity metric, develop a BNG plan, and ensure compliance with the legal requirements.

Consultants can also help developers navigate the challenges and risks associated with BNG, such as the potential for legal disputes or reputational damage if the net gain is not achieved. By providing expert advice and support, consultants can play a crucial role in ensuring that development projects are both economically viable and environmentally responsible.

In conclusion, BNG is a crucial requirement for developers in today’s sustainability-focused world. By understanding the legal requirements, planning effectively, engaging with local communities, and consulting with environmental experts, developers can ensure that their projects contribute positively to biodiversity and hence, to sustainable development.

Complying with BNG through Biodiversity Credits and Units

Another significant aspect in meeting the BNG requirements is the use of biodiversity credits and units. In situations where it is not feasible to achieve the compulsory 10% net gain on the development site itself, developers can opt for biodiversity credits.

Biodiversity credits are a measure of the potential benefit to biodiversity that a project can deliver, typically through off-site habitat creation or enhancement. Each credit represents a specific amount of biodiversity gain, with more credits equating to greater benefits for biodiversity.

These credits can be bought and sold through the biodiversity market, allowing developers to offset their impacts in one area by contributing to biodiversity improvements elsewhere. This not only helps to achieve the required net gain, but can also provide additional benefits such as supporting local conservation projects or boosting the local economy.

Moreover, the UK government uses biodiversity units to measure the value of habitats before and after a development. The number of units is calculated based on the type, condition, and strategic significance of the habitat, using the biodiversity metric. By comparing the number of units before and after the development, the planning authorities can assess whether the project has achieved the required net gain.

It’s essential to remember that while biodiversity credits and units provide a flexible approach to achieving BNG, they should not be used as a substitute for avoiding or minimising harm on the development site wherever possible. As per the mitigation hierarchy, off-site compensation should only be considered as a last resort.

Mandatory BNG and Its Implication on the Built Environment

Making BNG mandatory has significant implications for the built environment. It pushes developers to reconsider their approach to project planning and design, to ensure that buildings and infrastructures are not only functional and aesthetically pleasing but also contribute positively to local biodiversity.

This shift can lead to various benefits for the built environment. For instance, incorporating green spaces into urban developments can enhance the quality of life for residents, providing opportunities for recreation, improving air quality, and even reducing the urban heat island effect.

Moreover, a focus on BNG can promote the use of sustainable building materials and construction methods, which can reduce the environmental footprint of the built environment. It can also encourage innovative design solutions, such as green roofs or walls, which can provide habitats for a range of species while also improving building performance.

However, it’s worth noting that achieving BNG in the built environment can be challenging, particularly in densely populated urban areas where space for biodiversity enhancement may be limited. In such cases, it’s essential for developers to seek expert advice and work closely with planning authorities to find effective solutions.

In conclusion, mandatory BNG, while challenging, presents a unique opportunity to transform our built environment into a more sustainable and biodiverse one. By understanding and effectively applying the principles of BNG, developers can not only comply with the legal requirements but also contribute to a more sustainable future. Ultimately, it’s about balancing the need for development with the need to protect and enhance our precious biodiversity.
