Western Sydney International Airport (WSI) released its inaugural Sustainability Strategy this week, cementing a net zero path for Scope 1 and 2 emissions. The greenfield facility, set to open 25 October 2026, will operate on 100% renewable electricity from day one via a 15-year CleanPeak Energy contract. This deal includes a 30MW/120MWh on-site battery and 9MW new rooftop solar, avoiding 64,000 tonnes CO₂-e annually. Freightquip will supply an almost entirely electrified Ground Support Equipment fleet, establishing Australia’s first airport-wide GSE pooling program. The strategy benchmarks sustainable aviation fuel integration, unlocking SAF value chain investment, though Scope 3 targets remain unspecified.
