While serving almost 17 million passengers, Austin Bergstrom International Airport (AUS), TX, has continued to work with ACI’s Airport Carbon Accreditation (ACA) programme, with the goal to reach carbon neutrality in 2020.
AUS was recently awarded for becoming re-certified at the second level of the four-step process. In 2019, Dallas Love Field was also recognised for achieving Level 2 Carbon Accreditation. Out of all North American airports, the only airports that have achieved Level 3+ accreditation – meaning carbon neutrality has been reached – are San Diego International Airport (SAN) and Dallas/Fort Worth International Airport (DFW). Both AUS and Dallas Love Field are committed to joining this elite group by 2020. Also focused on reducing carbon emissions, two of the state’s largest cities and three of the state’s largest airports have created the Texas Airport Climate Alliance to collaborate, share resources and accelerate action on climate change. AUS has used a variety of tactics to reduce its carbon footprint including using wind and solar-energy sources, alternative fuel vehicles, conservation awareness campaigns and purchasing carbon offsets. Electrical power for all AUS buildings is supplied by Austin Energy’s GreenChoice programme, generated by west Texas wind turbines. The airport has used 100% renewable electricity since 2012, thereby preventing more than 93,000 t of CO2 from entering the atmosphere. The use of this power source has been extended from the terminal to the airfield to power aircraft ground service equipment (GSE) and aircraft ground power units.
