How Wellington Airport built the data foundation behind ACA Level 4+ and a 98/100 GRESB score

By partnering with BraveGen, Wellington Airport tripled the scope of its GHG inventory without adding headcount — while spending less time on it than before. The airport achieved 100% organisational boundary coverage, scored 98/100 in GRESB FY25, and now runs its ACA Level 4+ Transition, sustainability-linked loan assurance, and climate disclosures from a single audit-ready system of record.
