Hey you, don’t watch that, watch this. If it hadn’t been for the pesky BBC piece at the beginning of the day, the Government’s press statement Biodiversity Net Gain moves step closer with timetable set out (27 September 2023) would have been a terrific piece of spin.
The statement announced much awaited progress on the nuts and berries of biodiversity net gain (see eg my 2 October 2021 blog post Ecology By Numbers: Biodiversity Net Gain In The Environment Bill (and further back my 30 March 2019 blog post Biodiversity Net Gain: A Ladybird Guide).
How precisely will the complex regime introduced by the Environment Act 2021 be implemented in practice? There was good news in the statement:
“By the end of November, we will publish all guidance and the regulations including:
• the statutory biodiversity metric, critical for calculating the correct biodiversity gain
• the draft biodiversity gain plan template, which will help developers prepare for what they will need to complete during the planning application stages
• the Habitat Management and Monitoring Plan template, which will set out how the improved significant on-site and off-site habitats will be managed for the long term
• a package of Biodiversity Net Gain guidance that sets out further advice for landowners, developers, and Local Planning Authorities around their role and responsibilities in delivering mandatory Biodiversity Net Gain
These materials will ensure that developers and planning authorities have access to the necessary tools and information to effectively implement Biodiversity Net Gain in January 2024, ensuring they deliver the homes that the country needs while benefitting nature and local environments.”
The awkward bit? We weren’t just expecting the guidance and regulations, all much delayed, but November 2023 was to be when the regime was actually to be implemented! Whoops. BNG for small sites had already been pushed back to April 2024 and BNG for nationally strategic infrastructure projects was always going to be later, but since 2019 DEFRA’s position has been that the BNG regime would come into effect two years after the Act received Royal Assent (9 November 2021). Whoops again.
Of course the work is difficult – it’s a forbiddingly complex regime, quantifying biodiversity numerically and effectively creating a state-backed credits-trading system. But we all knew that – and said as much during the passage of the Bill. Back in my 2021 blog post I naively hoped that the delays in the Bill would allow progress to be made on much of this as the Bill progressed. What have the array of ministers that we have had in DEFRA and DLUHC since 2019 actually been doing?
It isn’t just the Government that needs more time to complete its homework. The system relies on local government knowing what it is meant to be doing and being sufficiently resourced to cope with its new responsibilities. Earlier in the month, the RTPI was raising concerns on behalf of its members, RTPI publishes worrying new data ahead of Biodiversity Net Gain implementation deadline (7 September 2023):
A “survey of our RTPI members found that:
- 61% of public sector planners cannot confirm they’ll have dedicated BNG resource and ecological expertise in-house in place by November.
- 79% of public sector planners believe that BNG practice would be improved with confirmation of additional ‘skills and staff’
- 78% of public sector planners believe that BNG practice would be improved with additional ‘guidance, advice and support’
- 54% of planners across the public and private sector believe that BNG practice would be improved by giving ‘case studies of best practice’”
Let’s hope they are in a better position by January.
In another part of the forest, concerns as potential unintended consequences of the BNG regime were raised by the House of Lords Built Environment Committee in its 21 September 2023 report The impact of environmental regulations on development:
“Biodiversity net gain
178.Liz Hart told the committee that the biodiversity net gain (BNG) requirement is “putting developers off brownfield sites”. Remediation of a brownfield site, such as removing contaminated soil, can have a negative impact on biodiversity irrespective of any benefits from the removal of contaminants. If the same BNG metric applies to greenfield and brownfield sites, there is no incentive to fund remediation: a developer risks making a substantial financial outlay to remediate a site only to result in potentially significant negative BNG with further investment then being required on mitigation. We heard that the development of brownfield sites may depend on larger developers building on greenfield land to create a surplus of BNG credits.
179.The Minister for Natural Environment and Land Use agreed that where remediation involved removing contaminated soil that was beneficial to wildlife it would have a negative impact on BNG. However, she suggested many brownfield sites have low biodiversity value or will be below the de minimis threshold. The Wildlife Trust disagreed, suggesting this is often “far from reality” with brownfield sites commonly being successional habitats, home to a variety of rare species.
180.Brownfield development is a key government policy supported by the public and vital to delivering homes. The Government should ensure that remediating brownfield sites is not disincentivised by biodiversity net gain requirements. Local planning authorities should be able to moderate biodiversity net gain requirements for sites on their brownfield registers.”
I have a sense that implementation of this regime is only going to be the start. In the meantime, even this relatively short two months’ delay (assuming the latest commitment is met) sends another really poor signal as to (1) this Government’s ability to deliver on its promises and (2) as to the lack of priority that it would appear to be giving to the environment.
