MarillionEx Public Registry

Every Vintage Water Credit (VWC) represents exactly 1 m³ of verified water benefit — measured, stress-weighted, and independently traceable. Credits may only be retired, not re-sold — ensuring each unit has a single, permanent contribution.

All issuance records are publicly auditable. Serial ranges are unique per vintage, mechanism class, and project. Project owners are anonymised — only region, watershed, and mechanism class are disclosed.
