Back in September 2021, the AIRPOWER22 project team was instructed by Defense Minister Klaudia Tanner to plan and implement AIRPOWER22 as a “role model” for a sustainable major event. The topic of sustainability was therefore a top priority for all those responsible and was a cross-cutting issue throughout all planning stages for AIRPOWER22. The final sustainability report is now available, which shows clear successes in reducing the CO2 balance. Over 3,357 data records with around 17,000 individual entries in 106 data groups were evaluated and compared with existing data from 2019. These show a saving of 18 percent CO2 equivalent per capita; the declared target for 2021 was 15 percent.
