EXCLUSIVE: Analysis Uncovers Impact of Biodiversity Net Gain Schemes: Equivalent to Over 200,000 Round-Trip Flights from London to New York Annually
In a groundbreaking revelation, the habitats cultivated under England's innovative Biodiversity Net Gain (BNG) initiatives are projected to absorb a staggering 650,000 tonnes of carbon dioxide annually. This astonishing figure, akin to the emissions offset by nearly 200,000 round-trip flights from London to New York, underscores the monumental potential of these conservation efforts.
Introduced on 12 February, the new mandates require developers to achieve a minimum net biodiversity enhancement of 10 percent for most planning applications, as per metrics established by the Department of Environment, Food and Rural Affairs (Defra).
Should on-site enhancements fall short, developers must finance off-site conservation projects or procure biodiversity credits to meet the stipulated gain threshold.
A comprehensive analysis of the government's Net Gain Impact Assessment by biodiversity tech pioneer Joe's Blooms sheds light on the transformative impact of these regulations. The study forecasts an annual addition of over 15,000 hectares of biodiverse landscapes across England, equivalent to approximately 23,500 football pitches of natural habitat.
Furthermore, with the government targeting the construction of 300,000 new homes annually, this initiative could create 5,699 hectares of fresh habitats while preventing the degradation of 10,085 hectares of existing ecosystems.
Delving deeper into the habitat distribution across the nation, the research underscores the carbon sequestration potential of resultant woodlands, heathlands, grasslands, and wetlands. The cumulative effect is tantamount to mitigating emissions equivalent to 4.6 billion kilometers of average car travel.
"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," said Robin McArthur, chair of the Joe's Blooms Advisory Board.Â
"Developers and local authorities have an opportunity to build the homes we so desperately need while also making a nature-positive contribution to the climate crisis."
While large-scale developers have already commenced compliance with BNG requirements, smaller developments have until 2 April to implement these regulations. Nationally significant infrastructure projects are slated to adhere to BNG standards by late November 2025.
Beyond carbon sequestration, the expansion of woodlands, heathlands, grasslands, and wetlands promises to safeguard England's indigenous flora and fauna. Recent findings from the Woodland Trust reveal a concerning decline in one-third of all woodland species, underscoring the urgent need for conservation efforts like BNG.
Advocates assert that BNG has the potential to revolutionize the role of the built environment in nature restoration and climate resilience, marking a significant stride towards addressing ecological and climatic challenges head-on.
