The AUS shuttle bus fleet has historically utilised alternative fuels. To ensure continued operation, half of the fleet utilises propane, and the other half is compressed natural gas (CNG). As of 1 January, AUS started fuelling half of its shuttle bus fleet with RNG, an ultra-low carbon fuel that is cleaner than traditional compressed natural gas (CNG). This will reduce the AUS carbon footprint by approximately 20% at no extra cost to the airport.
