Five-acre elevated walkway to act as a green gateway between the University of Salford’s campus and Crescent innovation zone Construction of Salford Rise – a transformative element of the wider £2.5bn, 252-acre Crescent Salford masterplan – has begun. Delivered by ECF – a joint partnership between Legal & General, Homes England and Muse on behalf of Salford City Council – the infrastructure and public realm project will remove physical barriers between the communities to the north of the Crescent area, replacing them with walking and cycling routes focused on accessibility and active travel, significantly improving connectivity between these communities and Crescent Salford. In addition, there will be large areas of new, high-quality green spaces, trees, planting and public squares for pop-up events and festivals. At the heart of the ambitious regeneration of Salford Crescent, is a near five-acre elevated walkway spanning Frederick Road which will enhance connectivity and act as a key gateway between the University of Salford’s campus and the Crescent innovation zone. Eric Wright Civil Engineering has been appointed as the main contractor to deliver the walkway designed by MAKE, Planit and Cundall. It stands at 11 metres wide and 220 metres long and will be a green and safe haven for pedestrians and cyclists, encouraging active travel and facilitating improved collaboration across the development. The project is partially funded by £13.17m from the Government’s Levelling Up Fund. Preparatory and ground works will be carried out for the remainder of 2024, while work on the bridge structure is expected to begin in early 2025 and complete in summer 2026. Salford Rise forms a key part of the Crescent masterplan which will deliver more than 3,000 homes, 1m sq ft of offices, retail and leisure, a multi-model transport hub and vast areas of green space. Commencement of work on the project follows the approval of plans by Salford City Council to bring forward Crescent Innovation, another pivotal element of the Crescent Salford masterplan. Creating a high-quality innovation ecosystem around the University of Salford, Crescent Innovation will build on existing world-class research and development capabilities; help drive further economic growth in the city and wider region; and facilitate enhanced links between academia, research, and business. Salford Rise will physically connect economic assets across the innovation zone to unlock significant development opportunities and enable collaboration between academia and industry. Salford City Mayor, Paul Dennett, said: “I am delighted that this important project is now moving into the delivery phase. Salford Rise will better connect our communities to the Crescent and University campus and provide transformational change across Crescent Innovation, helping to unlock world-class innovation-led research and development opportunities that Salford residents and businesses can benefit from.” Vice-Chancellor at the University of Salford, Professor Nic Beech, commented: “Salford Rise is a great example of innovative regeneration work as part of the wider Crescent masterplan to benefit our Salford community, connecting people and fostering collaboration between businesses. This work will develop and enhance our local environment and provide vital sustainable travel options for students, colleagues, and visitors accessing our University campus and the surrounding areas.” Max King, Project Director (North West) at ECF, said: “Starting on site at Salford Rise and seeing the first spade in the ground marks a landmark staging post as we begin to bring the vision for Crescent Salford to life. This project is a pivotal part of the wider masterplan, and particularly the innovation zone, unlocking opportunities and fostering collaboration to enable the people that live, work and study in Salford to thrive.” Building, Design & Construction Magazine | The Choice of Industry Professionals
Environment Bank has recently announced that it is working in collaboration with Barclays to support greater visibility and adoption of Biodiversity Net Gain (BNG) among housebuilders and England-based farmers. Environment Bank offers Biodiversity Units to developers to enable them to fulfil their BNG obligations. It works with farmers and landowners to generate these units by building ‘habitat banks’, supporting farmers to increase biodiversity, unlock a diversified revenue stream and build business resilience for their farms. BNG is an initiative that aims to make sure that property development in England has a measurably positive impact on biodiversity. To comply with the Environment Act 2021, developers in England must deliver a 10% net uplift in biodiversity relating to the site to be granted planning permission. Barclays’ developer clients will be able to purchase off-site Biodiversity Units from Environment Bank from a network of habitat banks around the country. As part of the collaboration, Environment Bank and Barclays are also highlighting opportunities for farmers and landowners to explore the BNG market as an avenue of accessing Nature markets, through Environment Bank’s model where it takes a 30-year lease on areas of land to deliver the biodiversity gains. Commenting on the collaboration, Catherine Spitzer, CEO of Environment Bank, said: “We are delighted to be working with Barclays and look forward to helping both its developer and agricultural clients to navigate the BNG market.” “I hope that working closely with Barclays’ clients in this way will make a significant contribution to nature restoration in England.” Adam White, Head of Agriculture, Barclays UK said: “Not only does BNG support farmers and landowners to explore possible new revenue streams, but it also supports biodiversity uplift across the England and is a route for developers to comply with this new regulation. “This collaboration with Environment Bank helps ensure our customers are getting support to understand what is right for their business.” Environment Bank has already established a network of 28 Habitat Banks over almost 2,000 acres across England – with more than 20 additional sites already in development. It has a team of 85 experts working across ecology, land management, planning, and legal services. Its clients comprise SME and major housebuilders alongside significant commercial, utility, energy, and infrastructure developers.

By Tara Garraty, Biodiversity Specialist and Sustainability Scientist – Tunley Environmental As more buildings and developments continue to sprout across the UK, Biodiversity Net Gain (BNG) has become a crucial part of the government’s strategy for environmental sustainability. BNG is a framework that ensures that any new development contributes positively to biodiversity. The goal is to leave the environment in a better state post-development than it was before. Developers are required to assess the biodiversity value of a site before and after development, with a target of achieving a minimum 10% net gain in biodiversity. Traditionally applied to larger projects, from April 2024 BNG now extends to smaller sites as well, following an update from the Department for Environment, Food & Rural Affairs (Defra). The Small Sites Update: What’s New? Historically, BNG was a requirement primarily for larger developments. However, with the new regulation, small developments—defined as those under a hectare in size or involving fewer than nine dwellings—are now also subject to BNG rules. This expansion recognizes that cumulative impacts from smaller projects can significantly affect local biodiversity. To aid in the assessment of these smaller projects, Defra introduced the Small Sites Metric (SSM) calculation tool, a simplified tool adapted from the existing statutory biodiversity metric calculation tool, to help measure the biodiversity value of smaller sites, making it easier for developers to meet the BNG requirements. Why BNG Matters for Small Developments In the word of Tunley Environmental’s Biodiversity Specialist Tara Garraty “Implementing biodiversity net gain on small sites allows one to maximise ecological benefits across all scales, ensuring that every development, regardless of size, contributes to the restoration and enhancement of local biodiversity. This approach fosters a more resilient and sustainable environment for future generations.” The Small Sites Metric To assess and quantify the biodiversity impact of small developments, the UK government introduced the Small Sites Metric. This tool provides a simplified method for calculating the biodiversity value of a site, making it easier for developers of small projects to meet the BNG requirements. The metric considers factors such as habitat quality and area, guiding developers on how to achieve the mandatory 10% net gain in biodiversity. Steps to Implementing BNG in Small Developments Baseline Assessment: Start by evaluating the existing biodiversity of the site using the Small Sites Metric. This involves identifying and quantifying the types and quality of habitats present. Design and Plan: Develop a plan that outlines how the project will achieve at least a 10% net gain in biodiversity. This could include enhancing existing habitats, creating new ones or improving habitat connectivity. Implementation: Carry out the planned biodiversity enhancements during the construction phase and ensure ongoing management to maintain the biodiversity gains. Monitoring and Reporting: Regularly monitor the outcomes and report on the biodiversity improvements to relevant authorities. Who Should Comply with New BNG Regulations? Although, updates to BNG regulations applies to anyone involved in the construction and sustainability industry, it is particularly vital for developers, landscape architect or planner working on small development projects. Developers of Major Developments: Developers undertaking major projects, that typically involve large-scale construction activities, such as residential complexes, commercial buildings or industrial facilities, are required to incorporate BNG principles into their project planning and execution. This might include measures like creating green spaces, enhancing habitats or offsetting biodiversity losses through conservation projects elsewhere. Developers of Small Sites (Effective from 2 April 2024): This extension recognizes that even small developments can significantly impact local biodiversity. Developers of Nationally Significant Infrastructure Projects (Effective from Late November 2025): From late November 2025, developers involved in nationally significant infrastructure projects, such as highways, railways and energy installations, will also need to comply with BNG regulations. These projects often have large footprints and can impact vast areas, making it essential to implement strategies that mitigate biodiversity losses. Land Managers Wanting to Sell in the BNG Market: BNG regulations also open up opportunities for land managers and owners to participate in the biodiversity market. By enhancing or restoring habitats on their land, they can generate biodiversity units that can be sold to developers needing to offset their biodiversity impacts. Local Planning Authorities (LPAs): Local Planning Authorities (LPAs) play a critical role in enforcing BNG regulations. They are responsible for reviewing and approving development proposals, ensuring that BNG assessments are properly conducted and that plans meet the required standards. Implications and Future Updates The inclusion of small sites under the BNG umbrella signifies a broader push towards comprehensive biodiversity protection. Developers, planners and landowners must now integrate biodiversity considerations into all scales of development projects to align with legal requirements and support global environmental and sustainability goals. Future Updates and Considerations: Continued Evolution of Metrics: As the understanding of biodiversity and ecosystem services deepens, the metrics and tools used to assess biodiversity impacts will likely keep evolving. This could include more nuanced metrics that consider ecological connectivity and specific landscape. Increased Regulatory Scrutiny: As enforcement mechanisms strengthen, developers may face more rigorous scrutiny to ensure compliance with BNG targets. Wider Adoption of BNG Principles: Beyond statutory requirements, there’s an increasing trend towards voluntary adoption of BNG principles by businesses and organisations committed to sustainability. Tara emphasises the strategic importance of integrating biodiversity into future planning efforts, stating, “As BNG becomes integral to planning, future considerations for developers will increasingly focus on innovative design and the integration of green infrastructure even on small sites. By prioritising nature-inclusive solutions, developers can contribute to larger ecological networks, enhancing habitat connectivity and resilience in the face of climate change. This forward-thinking approach will be crucial in meeting both environmental goals and regulatory requirements in the years ahead.” The Bottom Line The extension of BNG requirements to small sites marks a significant step in the UK’s biodiversity conservation efforts. Traditional metrics and frameworks often overlook these sites, despite their collective impact on local biodiversity. For developers and stakeholders, understanding and implementing these requirements is crucial for legal compliance and contributing to broader environmental goals. As the regulatory landscape continues
A TRIO of new starters has joined leading carbon and biodiversity offsetting solutions provider CSX. The appointments expand the firm’s capacity, helping deliver strategic growth in its role as providers of biodiversity net gain (BNG) and carbon offset units. The company uses earth observation technologies and data analysis systems to collect and accurately analyse carbon storage and biodiversity data. This process has quickly become crucial for land developers and owners with the government’s introduction of BNG in February 2024. This new approach requires any new development to have a positive impact, or ‘net gain’, on the land biodiversity of at least ten per cent. This ensures that wildlife habitats are left in a measurably better state than they were before. Joining CSX’s expert team as BNG project officers are Kennedy Young and Heather Scollick, while Steven Crosby has been appointed a business development executive at the company’s North Yorkshire office. Kennedy and Heather are tasked with helping landowners develop their BNG projects, overseeing them from start to finish as well as advising, finalising and communicating plans with local authorities. Steven will be responsible for supporting developers, planning consultants and stakeholders in the construction sector to navigate the successful delivery of BNG on their projects. He will also secure any shortfall in units from the land managers who CSX has supported in the creation of off-site units for sale. Previously Kennedy worked at ecology and design practice FPCR as a seasonal assistant ecologist and has studied animal science and welfare. Kennedy said: “CSX has an important mission which I am more than happy to be part of. BNG is a significant change for the sector and people are understandably wary about what is now expected of developments. It’s my job to make sure that the benefits of BNG are known, but also the processes are as simple and accessible as possible. Heather said: “CSX is leading in this field, so it’s an honour to be part of the team. It’s not just about progressing these important BNG projects, but also progressing the wider knowledge of the environment, species identification, trees and general habitats. It’s important that we utilise all resources at our disposal, especially technology, to tackle this problem head on.” Steven, tasked with making sure key stakeholders are engaging in the BNG process and helping to relieve the pressure on them, said: “I’m looking forward to getting stuck into the role. Being able to talk to these different groups of people and assist them in something this significant is rewarding. It’s about having clarifying conversations about BNG – there’s a lot of information and it can be intimidating. But it doesn’t have to be.” Andy Howard, CSX’s co-founder and chief executive officer, said: “It’s a pleasure having Kennedy, Heather and Steven bolster our team across these two key departments. “At CSX we are focused on strategic growth and the awareness of what we can do and how we can help both landowners and developers. “We want to make sure we are at the forefront of the discussions around biodiversity net gain in the sector and we do that by having a dedicated team from varied backgrounds with a similar passion for the environment. I look forward to seeing the great work they accomplish with our projects and clients.” Building, Design & Construction Magazine | The Choice of Industry Professionals
The National Audit Office has stated new Biodiversity Net Gain (BNG) requirements have been launched without all the necessary elements for successful implementation. In February, as BNG laws came into effect, the Royal Town Planning Institute (RTPI) noted that 81% of planners in the public sector needed further ‘guidance, advice, and support’, 68% of all planners needed more staff and skills, and 61% require more case studies of best practice, according to a survey of RTPI members. The RTPI is closely monitoring BNG’s impacts on the planning system. The Institute is encouraging members to share their experiences by filling out its BNG survey and sharing case studies of best practice. Victoria Hills, Chief Executive of the RTPI, said: “Our members in public and private sectors said that they felt unprepared for Biodiversity Net Gain in the lead up to its implementation. We worked to voice these concerns to the government, calling for clear guidance on BNG and sufficient resources to local planning authorities operating this new system. “We would like to see the implementation of Biodiversity Net Gain succeed and are pleased that our engagement on this subject helped secure further funding for planning services to implement BNG. “However, the conclusions outlined by the NAO today reflect what our members have been consistently telling us for some time: that planning services have not been given sufficient guidance, advice, and support, and lack the staff and skills to avoid delays to an already stretched planning system. We strongly support the principles of BNG, but any new burdens to the planning system need to be adequately supported. “We agree with the recommendations made by the NAO. To facilitate local delivery, the Department for Environment, Food and Rural Affairs must ensure local authorities have sufficient funding, monitor the biodiversity units market, identify regional impacts, and work with planners and ecologists to coordinate best practice among local authorities.” Building, Design & Construction Magazine | The Choice of Industry Professionals
Natural habitats created by new biodiversity laws could absorb up to 650,000 tonnes of carbon dioxide each year, the equivalent of nearly 200,000 round trip flights from London to New York, according to new research from biodiversity tech start-up Joe’s Blooms. Based on the Government’s Net Gain Impact Assessment which shows that new regulations could see England benefit from over 15,000 hectares of biodiversity each year, the research analysed the carbon storage potential of the natural habitats that this increase could create. Looking at the distribution of different habitats across the UK, the research found that the carbon storage potential of woodland, heath, grasslands, and wetlands equates to emissions released from 4.6 billion kilometres of driving an average car. The increase in habitats that absorb carbon dioxide is down to the new Biodiversity Net Gain law (BNG) – a first-of-its-kind planning policy that requires developers to invest in measures that increase the amount of plants and wildlife in the local area by 10%. As well as the carbon absorption potential, increasing woodlands, heath, grasslands, and wetlands through the new BNG policy will protect England’s native plant and animal species – with recent data from the Woodland Trust finding that one-third of all woodland species are diminishing. The analysis comes as recent data from the European Earth Observation Agency shows global annual temperatures have for the first time breached the critical benchmark of 1.5C above pre-industrial levels set by the United Nations, with January 2024 being the hottest start to a year on record. Scientists around the world have long argued nature restoration is central to tackling the climate crisis. Research shows that over the past 10 years, ecosystems and the biodiversity they contain have absorbed 54% of human-made carbon emissions. Natural habitats also provide important solutions to more extreme weather patterns such as increased rainfall, with analysis showing that biodiverse land decreases flood exposure by up to 70%. With the policy mandatory for small developments as of April 2, this research demonstrates that BNG will play a key role in boosting natural habitats across England and supporting the UK’s efforts to fight global warming. Robin McArthur, Chair of the Joe’s Blooms Advisory Board, said: “This analysis adds to mounting evidence that nature recovery fuelled by BNG, whether it’s restoring wildlife-rich habitats or creating green corridors to bridge together fragmented habitats, will play a central role in boosting the UK’s resilience to climate change. Developers and local authorities have an opportunity to build the homes we so desperately need whilst also making a nature-positive contribution to the climate crisis.” Building, Design & Construction Magazine | The Choice of Industry Professionals
As the government’s biodiversity net gain (BNG) requirement for developers becomes mandatory, national property consultancy Carter Jonas has announced the significant sale of over 200 units in Cambridgeshire. Legislation comes into force across England this week ruling that planning applications for all major developments must include provision for BNG of at least 10% so habitats are left in a better state than they were pre-development. Previously, developers needed to ensure any damage done to biodiversity was offset, but new regulations mean they must also provide an additional 10% gain. If applicants cannot provide this extra 10% on site, they will need to purchase BNG units off site, which is where the opportunity exists for landowners. In what is one of the first large-scale public sales of its kind, Carter Jonas is acting for Ground Control’s Evergreen Fund to market The Devana Centre for Environmental Recovery in West Wickham, Cambridgeshire. Mark Russell, Partner at Carter Jonas, said: “The introduction of mandatory BNG has been a long time coming but will now open opportunities for landowners who are interested in the natural capital markets. “Selling units is a big commitment as the land must stay in the scheme for a minimum of 30 years, so decisions should be made within the context of a long-term strategy for the farm or estate. “In the case of the Devana Centre, there is a clear plan and a strong desire from the Evergreen Fund to deliver nature recovery, so the natural capital route is a really good option.” Ground Control is a UK-based grounds maintenance company and The Devana Centre forms the latest example of its Evergreen Fund’s commitment to building a network for nature recovery through direct action. It is the Evergreen Fund’s second site, adding to its 296-acre Wildfell Centre for Environmental Recovery in Braintree, Essex. Chris Bawtree, Nature Recovery Director for the Evergreen Fund, said: “Devana represents a key part of Natural Cambridgeshire’s ambition to double land managed for nature across the region from 8% – one of the lowest in the country – to 16% which is the national average. “The new location will provide a home for 20-25 native tree species, 15-20 native shrubs, a wide variety of native wildflowers and grasses, creating valuable habitats for a range of other fauna such as pollinators, birds, bats, mammals and reptiles. “The land will also provide corridors for biodiversity to spread by linking directly into the Cambridgeshire Green Infrastructure network via woodland and hedgerows on site and the neighbouring semi-natural ancient woodland Rand’s Wood.” The price range for BNG units from The Devana Centre starts from £22,500.

As the requirement becomes compulsory In advance of the statutory requirement for biodiversity net gain (BNG) for new developments from January 2024, Carter Jonas has analysed the emergence of BNG policies and guidance within local planning authorities (LPAs) in a series of research from spring 2022. Carter Jonas’ Q4 2023 research of the 306 LPAs in England has revealed a gradual increase in the number requesting in excess of the 10% biodiversity net gain. The local plans of Guildford, Brighton and Hove and Worthing (1% of all LPAs) require or encourage a percentage net gain higher than 10%. However, this figure is set to increase substantially as 17 (5.6%) have such a policy emerging through their local plan review. This is an increase of 33.3% from our Q4 2022 research. Although not included in the analysis because of the early stage of adoption, numerous LPAs are actively considering a higher level of net gain, including Birmingham and Chelmsford. Kingston Upon Thames and Tower Hamlets are set to have the most ambitious policies to date: both would require a minimum of 30% net gain but these policies are emerging through the local plan process and not yet adopted. Commenting on the importance of the research, David Alborough, Natural Capital Consultant at Carter Jonas said, “Our analysis provides developers, landowners and planning consultants with valuable insight into where the greatest demand for off-site BNG is emerging, which has important implications for developers and identifies opportunities for landowners.” Specifically, the research identifies some significant regional variations. BNG policies with a requirement in excess of 10% tend to be located in the south of England. In the South East, 11 LPAs have a BNG policy (either emerging or adopted) calling for greater than 10% net gain, accounting for 16.7% of LPAs in the region. This compares starkly to the North West, North East, West Midlands and East Midlands where no LPAs make this requirement. Sophie Davidson, Associate in the Research Team explains, “Some regional variation can be attributed to the influence of Local Nature Partnerships, which is evident in the south. For example, the Kent Nature Partnership is promoting a county-wide target of 20% within Kent and Medway. In response to this, Kent County Council (with funding support from Natural England) commissioned a strategic viability assessment of BNG in Kent. The report concludes that the biggest cost in most cases is to get to 10% net gain, and the increase to 15% or 20% is ‘generally negligible’. This has influenced emerging policies in Sevenoaks, Maidstone, Canterbury and Swale so far, representing 30.7% of the county. Likewise, the Surrey Nature Partnership and Sussex Local Nature Partnership have directed higher net gain targets in their counties.” In addition to showing an increasing number of LPAs deviating from the national position, either in the percentage net gain required or in their guiding framework for delivery, Carter Jonas’ research also identifies which LPAs are adopting measures to direct investment to local sites and accelerate the local market. Sophie Davidson concludes, “In areas with higher net gain requirements, we can expect the local market to develop at a faster rate. Many LPAs have stalled their local plan reviews in the face of significant changes to national planning policy, so BNG policies have taken longer to develop than expected. But as changes are formalised and local plan reviews progress, expect to see more LPAs progressing higher levels of BNG. We are aware of several which have included an option to consider a greater scope for BNG in early consultations. “Conversely, LPAs may drop their emerging 20% BNG policy before adoption. For instance, Rossendale Borough Council was seeking a 20% net gain in its draft submission but reduced the requirement to the statutory 10% in its final local plan. “In the coming months, developers will be assessing their options and refining their BNG strategies. Meanwhile, demand for land for BNG will rise substantially, affording diversification opportunities for landowners.” Building, Design & Construction Magazine | The Choice of Industry Professionals
The Royal Town Planning Institute (RTPI) has published new evidence that shows planners are struggling to prepare for new Biodiversity Net Gain (BNG) requirements expected to begin later this year. The measures, introduced under the Environment Act, will require local planning authorities to assess and seek mitigation of the expected biodiversity net gain impact of planning proposals. They are expected to apply to new major applications from November 2023 and all minor applications from April 2024. However, an ongoing survey of our RTPI members found that: We also found public and private sector planners report having extremely low levels of confidence in the practical requirements of BNG, including core aspects of the scheme like ‘identifying BNG receptor sites’, ‘interpreting the robustness of ecological reports and BNG proposals’, ‘using the biodiversity metric’ and ‘negotiating with landowners over site provision’. Commenting on the results, RTPI Chief Executive, Victoria Hills has said: “These new findings show that government is running out of time to prepare local planning authorities to assess biodiversity net gain on major planning applications as expected in November. The RTPI fully support the scheme’s intention to improve our natural environment and we’ll continue to engage with Ministers and officials behind the scenes to urgently clarify the details of new BNG regulations, funding and training. Our research found that 25% of local authority planners have left over the last seven years. Immediate clarity and support will be crucial to the successful implementation of biodiversity net gain and to avoid adding to England’s planning backlog.” In response to government consultations, we’ve previously said that “legislation, guidance and metric can help to achieve [BNG] but must be complemented with proper resourcing for planners, including access to ecological expertise.” The RTPI’s latest survey results, collected between May and August 2023, add to a growing body of evidence that shows planners are concerned about the implementation of this new addition to their workload. Earlier this year, The Planner’s Careers Survey reported that 38% planners expected the ‘introduction of Biodiversity Net Gain requirements’ to be one of the biggest challenges they’ll face this year.

As habitats, wildlife, and plants remain at continued risk of loss across the globe, and the government’s new housing supply yearly target of 300,000¹ homes per year, it’s essential property developers are fully aware of the upcoming Biodiversity Net Gain (BNG) legislation and what this will mean for future planning and development.. With plans to protect fragile ecosystems and reverse the decline in species by 2030, all planning permissions granted in England (with a few exemptions) will have to demonstrate at least a 10% biodiversity net gain from November 2023. But what does this mean exactly for property developers? UK’s leading environmental consultancy, Thomson Environmental Consultants, summarises five things property developers should be aware of when it comes to Biodiversity Net Gain: Ultimately, BNG will aim to leave the environment in a better state than it was before. Introduced into legislation through the world-leading Environment Act 2021, achieving a 10% net gain will become mandatory for most developments from November 2023. Until now, local planning authorities, utility providers, housing developers, and other organisations have worked with National Planning Policy Framework guidance to seek net gain from new developments. However, from November, BNG will become a legal and mandatory process for most new housing, commercial and infrastructure developments which require planning permission under the Town and Country Planning Act 1990. Although some property types may be exempt from the mandatory BNG requirements, ¹ such as self-build homes; in most cases, property developers must demonstrate how they are replacing and improving biodiversity. The phased introduction of BNG, will allow smaller development sites a longer transition period (April 2024), and Nationally Significant Infrastructure Projects (NSIPs), which have been given development consent under the Planning Act 2008, will be required to comply with BNG requirements from 2025. Small sites are defined for the BNG exemption as residential and non-residential. Although the UK contains more than 70,000 known species of animals, plants, fungi and microorganisms, the growing pressure from diseases, invasive species and climate change has resulted in 600 million breeding birds being lost across the EU and UK since 1980, as well as 97% of the UK’s wildflower meadows, and 90% of the UK’s wetland habitats². In order to succeed the government’s commitment to halt species decline by 2030, BNG requirements are more critical than ever. Moreover, as the UK now only acquires half of the biodiversity that existed before the Industrial Revolution, it’s essential that equal efforts are placed to combat the increased threat to ecosystems while aligning with the government’s annual new home targets. This is where BNG comes into play. Property developers must assess the type of habitat affected and its condition before submitting plans detailing how they will deliver a 10% benefit for nature post development. The “biodiversity metric trading” rules require that any habitat affected within the boundary is replaced on a ‘like for like’ or ‘like for better’ principle. This will be done through the new and streamlined Biodiversity Metric 4.0, which includes a mandatory biodiversity metric calculator tool, user guide, small site metric calculator and more. The metric calculator will essentially provide a biodiversity metric to quantify the value of habitats before and after development. Newly available under the Environment Act 2021, conservation covenants will play an important role in conserving habitat and biodiversity in the long term. Conservation covenants will be an important mechanism for delivering ‘off-site’ BNG where meeting the mandatory 10% improvement on-site isn’t possible. The nature of conservation covenants will require a long-term commitment to the enhancement and maintenance of habitats. Government guidance suggests the BNG credits will be phased out over time as the private market for BNG becomes established. Although a secondary legislation draft is due to be published later in 2023 with further mandatory guidelines, it’s crucial property developers begin considering the requirements sooner rather than later in the planning process. Whether the new BNG requirements will apply to existing planning applications has not yet been confirmed and will be updated by DEFRA and the government accordingly. Regarding costings and project expectations, a government-run statutory credit scheme will be available as a last resort to prevent delays in the planning system. Developers can also pay for improvements on other sites elsewhere by purchasing “units” via a private, off-site market. However, in order to buy credits, property developers must demonstrate that they cannot deliver habitat onsite or via the off-site market. With credits costing between £42,000 and £650,000 +VAT, this will significantly add to overall project costs where off-site enhancements are required. Paul Franklin, Associate Director of Ecology at Thomson Environmental Consultants, commented on the legislation: “It’s important to remember that Biodiversity Net Gain will affect the property development process at all stages and phases. We strongly recommend early engagement with a consultant when undertaking due diligence on a prospective purchase through to consideration of the long-term monitoring and management of created habitats. In many cases, this will be a period of 30 years post-development. “Ensure you speak with consultants who have strong experts in conducting various project habitat surveys and condition assessments to ensure you achieve the desired biodiversity net gain.” To find out more about Biodiversity Net gain, visit: https://www.thomsonec.com/news/five-things-property-developers-need-to-know-in-preparation-for-biodiversity-net-gain-bng/ Building, Design & Construction Magazine | The Choice of Industry Professionals
