The aviation industry is intensifying its efforts to achieve net-carbon-neutrality by the self-imposed deadline of 26 years from now. The sector, historically slow in innovation, is now witnessing a surge in the development of technologies and advocacy for regulatory changes. Notable progress has been made, with the emergence of electrification and the construction of demonstrator aircraft showcasing tangible advancements. Start-up companies are also contributing to sustainability solutions, with a focus on e-fuels that promise a significant reduction in CO2 emissions compared to traditional sustainable aviation fuels. However, the high development costs remain a challenge, especially with governments like Germany cutting subsidies for research and development. The industry acknowledges the need for multiple solutions to address emissions, highlighting the importance of parallel technology paths. While hydrogen is seen as a potential future option, e-fuels are favored for their efficiency in the near term. The industry anticipates that current research will pave the way for future commercial aviation solutions. The key challenges ahead lie in establishing new regulations and policies to facilitate the mainstream adoption of sustainable technologies, ensuring both environmental benefits and cost-effectiveness for airlines and consumers.
