Previous Editions of TAC
The third and largest edition of TAC to-date brought together 24 participating airlines, including two airlines from outside the SkyTeam alliance for the first time ever. These airlines operated a combined 33 showcase flights to test and demonstrate innovative solutions that help enable sustainability progress.
More airlines, more flights, more innovations to help make flying greener. The TAC 2023 challenge was scheduled between 15 May – 28 May 2023 in which 22 participating airlines implemented their most sustainable solutions and competed for awards in 31 categories.
The Aviation Challenge 2022 focused both on the impact and contribution solutions. This year’s challenge delivered notable CO₂ reductions through operational improvements, advanced aircraft, and sustainable fuel. CO₂ intensity was 15% lower than our own baselines and 32.7% below the industry average, with 64% of flights using next-generation aircraft. Despite a 20.6% increase in RTK production, total CO₂ emissions per flight dropped by 4.4%. These results highlight our commitment to more efficient, sustainable air travel, setting the stage for continued progress in future editions.
