Early outcomes of England’s new biodiversity offset market

Led by Natalie Duffus. Natalie conducts the first academic analysis of what’s actually happening in the off-site BNG market. Natalie’s painstakingly assembled all of the available info on the off-site register, manually creating shapefiles from the drawn maps on the BNG register, identifying parcels of habitat from the aggregate statistics presented on the register as far as possible, & tracing each habitat transaction to its original development site across tens of LPA planning portals where possible. We have the habitat bank data & transactions data up to May 2025; & the first year of transactions (Feb 2024-2025) traced to demand sites.
