Sustainability metrics and carbon footprint

Sustainability metrics and carbon footprint

Queensland Motorways had published two sustainability reports, but allowed its carbon footprint to lapse. Change was afoot with the assumption of control over a major tunnel and a sale process which resulted in Transurban buying the company for $7.05B. Amid these changes, it sought to upgrade the rigour of its environmental metrics for its next sustainability report.

Scott investigated existing data sources, liaising with staff custodians, and cross-referencing to the Global Reporting Initiative (GRI) G4 Guidelines. He advised on obligations under National Greenhouse and Energy Reporting (NGER) and cloud-based versus spreadsheet solutions. The company decided to continue with a spreadsheet basis, which Scott then developed. The metrics tracking system combined all metrics using relational database structures to provide greater data validity and security.

As Queensland Motorways was integrated into Transurban, the sustainability metrics were already available to a high standard, easily blending with data for Transurban assets interstate and overseas.
