Case Study: Wellington Airport achieves audit-ready carbon reporting and a 98/100 GRESB score with BraveGen

Wellington Airport achieves 98/100 GRESB score and 100% boundary coverage with BraveGen

Wellington Airport, an aviation infrastructure operator, faced the challenge of managing its extensive carbon reporting and verification processes for programs like Airport Carbon Accreditation Level 4+ and GRESB with a small team. This manual effort, described as "death by spreadsheet," was time-consuming and cumbersome, especially for collecting data from tenants across its precinct. The airport partnered with vendor BraveGen and implemented its Carbon Accounting product to build a more robust data foundation.

BraveGen provided a complete carbon inventory system that automated tenant data capture via smart forms and created a digital twin of the airport's evolving operations. This solution allowed Wellington Airport to triple its reporting scope without adding headcount, significantly reducing data collection time. The results included a 98/100 GRESB score, a dramatically lighter path to ACA renewal, and higher confidence in data for audit assurance. BraveGen freed the sustainability team to focus on practical initiatives instead of administrative tasks.
