At the 41st General Assembly of the International Civil Aviation Organization ICAO in Montreal, 193 countries committed to reducing CO2 emissions from civil aviation to zero by 2050. To this end, the main focus is on the accelerated introduction of new and innovative aircraft technologies, rationalized flight operations and the increased production and use of sustainable aircraft fuels (Sustainable Aviation Fuels, SAF).
“This is a big step for climate protection, because CO2-free aviation is within reach. The technology for the production and use of SAF is there, the fuels can be used with existing propulsion systems and there is no need to change the fleet of airlines. Thanks to large-scale production in suitable regions with plenty of solar energy, the production costs are economically justifiable and the market-wide use of SAF is possible. Sustainable aviation fuels are already being used today: With Lufthansa and Austrian Airlines, passengers can already have SAF added to their flight bookings and thus reduce their CO2 footprint,” state Mag. Julian Jäger and Dr. Günther Ofner, Member of the Management Board of Flughafen Wien AG.
Globally, aviation causes only about 2.7% of all CO2 emissions (before the pandemic) – this is rather low compared to other industries. Nevertheless, international aviation is taking numerous climate protection measures. Vienna Airport is playing a leading role here: from January 1, 2023, Vienna Airport will operate in a CO2-neutral manner. To this end, the airport relies on numerous measures such as photovoltaics, e-vehicles, industrial use of waste heat, intelligent building management and much more. The airport operates eight photovoltaic systems at the site, including the largest system in Austria at 24 hectares. The Office Park 4 with geothermal use and photovoltaic system is currently the most sustainable office building in Austria. Overall, Vienna Airport has reduced its CO2 emissions by around 60,000 tons of CO2 per year compared to 2011.
