There are dangers to the long-term effectiveness of the federal government’s new Biodiversity Internet Acquire (BNG) coverage, launched in February, in keeping with a 17 Could Nationwide Audit Workplace (NAO) report.
The impartial public spending watchdog’s doc assessed whether or not Defra and Pure England have made good and efficient progress implementing statutory BNG, a coverage included within the laws of Defra’s 2021 Surroundings Act. The brand new guidelines – that are distinctive to England – require growth to have a measurably optimistic impression on biodiversity in comparison with what was there earlier than,1 seemingly the primary time a authorities has launched statutory BNG as a nationwide authorized requirement.
Builders should enhance the habitats they hurt by a internet 10%, ideally on-site. When on-site beneficial properties will not be sufficient to satisfy the ten% requirement, off-site beneficial properties could be created by the developer elsewhere or bought by way of a brand new non-public marketplace for biodiversity models.
BNG is being applied in three levels, with main developments in scope from February 2024; small developments from April 2024; and nationally important developments from November 20252.
Stakeholders assist the scheme, however had considerations about its implementation previous to launch. These considerations included uncertainty in regards to the launch and preparation prices.
The federal government supplied both £26,807 or £43,4674 to every native authority to assist them put together in every of the 2 years continuing launch. Native authorities had discretion to spend the cash: as an example, on recruiting and coaching new ecologists, procuring new software program, and processing authorized work. Nonetheless, Defra acknowledged blended readiness amongst native authorities at launch.
There are dangers to native authorities finishing up efficient compliance and enforcement for statutory BNG. Native authorities have discretion in how they implement planning laws. Defra didn’t give native authorities further cash particularly to observe or implement on-site gains4. Nonetheless, authorities expects that native authorities may also generate earnings from BNG authorized agreements, which might fund monitoring and enforcement work.
Defra remains to be growing its governance preparations for BNG and intends to make Pure England chargeable for vital components of the coverage. However in growing these new preparations, Defra doesn’t intend to offer central monitoring of how effectively on-and off-site biodiversity beneficial properties are being enforced by native authorities.
Pure England and Defra additionally lack all of the related data they should successfully consider the regime and decide whether or not it’s successful. As an example, they at present shouldn’t have a complete supply of knowledge of habitat enhancement going down on web site. Defra is exploring what data could be accessible from native authority reporting in opposition to the statutory biodiversity responsibility, though this can solely be accessible at five-yearly intervals.
Defra is counting on a non-public sector marketplace for biodiversity models rising however doesn’t know the way quickly it could scale up or fulfill demand. The place non-public markets fail to offer sufficient off-site credit, Defra will step in as a supplier of final resort, with the cash raised ring-fenced for presidency mandated enhancements to UK biodiversity. Presently, Defra doesn’t have a legally compliant mechanism to spend earnings from statutory credit score gross sales to boost biodiversity.
General, the federal government expects BNG to offer a small contribution to separate, nationwide biodiversity targets. Defra’s 2019 impression evaluation recommended that BNG, as designed, may very well be anticipated to ship real internet achieve, or not less than no internet loss.
The NAO recommends that authorities establishes a mechanism for spending earnings from the gross sales of statutory biodiversity credit. It additionally says that native authorities ought to have ample and well timed funding certainty to permit for longer-term planning relating to their function in domestically agreeing and implementing the scheme.
Gareth Davies, head of NAO, commented:
“The statutory biodiversity internet achieve scheme is the primary nationwide scheme of its form to construct necessities for enhancing biodiversity into planning approval. Nonetheless, it was launched with dangers to the long-term effectiveness of the coverage.
“These embrace uncertainty about whether or not the fledgling marketplace for biodiversity models scales as much as fulfill builders’ demand, dangers to enforcement and gaps in its data.
“Defra must address these issues, including by plugging gaps in its information so that it can effectively evaluate the scheme’s success.”
Responding to the publication of the NAO report, IEMA Director Coverage & Public Affairs, Ben Goodwin commented: “Getting Biodiversity Internet Acquire proper throughout totally different growth varieties and sizes is essential, however it’s a long-term endeavour and would require iteration to attain the most effective outcomes. The conclusions of the Nationwide Audit Workplace’s report are in keeping with this.
“Thinking about the health of the natural environment and its relationship with development more widely, we urgently need a framework in place that can marry-up disparate policy interventions on planning and environmental impact assessment reform, alongside BNG itself.”

[1] Defra and Pure England use habitat as a proxy for biodiversity.
[2] Main growth consists of residential developments with 10 or extra dwellings, or the place the positioning space is bigger than 0.5 hectares. Small web site growth consists of residential growth the place the variety of dwellings is, for instance, between 1 and 9, or if unknown the positioning space is lower than 0.5 hectares. Nationally important infrastructure initiatives are main infrastructure developments (equivalent to energy stations) that bypass regular native planning necessities.
