--- title: Challenges 2023 | TAC --- # People The Aviation Challenge is more than a competition. It is a reflection of identity and community. Each airline joins with its own custom logo, complete with a name and symbol that represent its unique vision and creativity. These personalized logos help spark internal excitement, build momentum, and bring visibility to the important preparation work happening across your teams. Together, they transform the Challenge into a vibrant showcase of innovation, collaboration, and aviation excellence. Result A total of 327 innovative solutions were submitted for TAC 2024 awards, each assessed by a diverse panel of aviation and sustainability experts, including members of the Netherlands Aerospace Centre (NLR). Awards were given across 18 subcategories, organized into three main categories: advancing adoption, boosting collaboration and empowering stakeholders. The award winners were selected by a jury of industry leaders from organizations including the Air Transport Action Group, American Express Global Business Travel and the UN Global Compact Network. server render fail/waiting for island-3bd6ecn841227R0 (separate island render, inside) Add Title Here 07-07-2026 01:04:15 ## Participants Participants in The Aviation Challenge are committed to finding new ways to reduce the industry’s footprint and help move more sustainable air travel forward.

Adopted Show More +1 Add Title Here - The TAC flights took place in the last two weeks of May – from 15th to 28th May. - Only solutions that were implemented in TAC were eligible for Awards. - Flights were to be round-trips, including turnaround, using an existing route. - The round-trip flight had to be a subsequent flight with the same registered aircraft (if operationally possible). - The scope for the Flight Impact Awards covered “below the wing” ground operations and flight operations. - Short Haul flight submissions were only eligible when the destination could not be reached by alternative transportation within 4.5 hours (measured from airport to airport. - There were two main Award types: ‘Flight Impact Awards’ (focused on sustainability impact) and ’Challenge Contribution

All averages were computed from the arithmetic mean of all metric values per airline/haul combination and are unweighted with respect to total CO₂, RTK, stage length, etc. 2. Own baselines consist of the averages of approximately 50 flights per airline operated with the same aircraft type and distance band in April 2022. 3. The average CO₂/RTK of the 22 TAC flights is a combination of medium- and long-haul flights, both excluding and including the full effect of SAF in tank. 4. The average CO₂ emission reduction factor is based on the specific fuel used on the five flights that uplifted SAF. 5. Ground emissions of the 14 flights participating in the “lowest CO₂ ground” category were compared using APU (4.75 gCO₂/RPK) vs APU alternatives (10.84 gCO₂/RPK). 6. On average per passenger over the 22 TAC flights, including meals, snacks, and beverages. 7. Average waste per passenger from 14 TAC flights participating in the “best waste management” category (0.28 kg/pax) compared to IATA’s 2019 Cabin Waste Handbook (1.43 kg/pax). May not be fully comparable due to differences in study criteria (e.g., untouched food, liquids, and cleaning waste).
