Every Biodiversity Net Gain unit gets an independent, checkable record of its delivery. Buyers and regulators verify the 30-year promise instead of trusting a PDF.
A BNG unit owes 30 years of delivery. Today the proof sits in management plans, spreadsheets, and monitoring reports. A buyer, lender, or council cannot check any of it independently. Unverifiable evidence caps the price.
| Product | A verified unit passport and a 30-year monitoring workflow. One system replaces per-site spreadsheets. |
|---|---|
| The evidence | Baseline survey, management and monitoring plan, every monitoring report, ecologist sign-off, dated site photos, satellite vegetation index. Each item is a signed claim carrying its date and author, and anyone can check it. |
| How we’d partner | Legacy is the first design partner. LinkedTrust builds and runs the platform. Legacy shapes it on real sites. The same platform then serves other operators, brokers, and councils. |
| What we’d do | Build the passport and monitoring platform. Load Legacy’s evidence. Connect the public register and satellite feeds. Publish a buyer-facing view. File LPA and Natural England reports automatically. |
| How it’s paid for | Build: grant funded (Defra NEIRF, Innovate UK). Ongoing: a per-site monitoring subscription and a per-unit provenance fee, paid from the management budget already priced into every unit. |
A buyer opens a unit and sees its baseline habitat, its last three monitoring dates, this month’s satellite reading, and the ecologist who signed each one. No email to Legacy required.
The record is identical for every unit, so one build covers a whole portfolio and every other operator. Auditable units are the ones institutional investors fund.
