Sustainability is one of the main challenges the aviation industry is currently facing. In a global context of energy transition towards cleaner and renewable sources, the sector is developing technologies to fly more efficiently and mitigate its environmental impact. Innovative propulsion alternatives such as biofuels, electric aircraft and hydrogen engines are already a reality or are close to becoming so. To assess their feasibility, a study is conducted on specific routes and aircraft across different flight ranges. The analysis focuses on the Canary Islands, an outermost region of the EU with high mobility and no comparable alternative means of transport. For three routes, flight profiles are analyzed, obtaining the fuel consumption and emissions generated by the conventional propulsion and later applying the sustainable alternatives. The results indicate optimistic perspectives, with reductions in environmental impact ranging between 40% and 75% compared to the present.

可持续性是航空业目前面临的主要挑战之一。在能源向更清洁和可再生能源转型的全球背景下，该部门正在开发技术以提高飞行效率并减轻其对环境的影响。生物燃料、电动飞机和氢发动机等创新推进替代品已经成为现实或接近成为现实。为了评估它们的可行性，对特定航线和不同飞行范围的飞机进行了研究。分析的重点是加那利群岛，这是欧盟最外围的地区，流动性高，没有可比的替代交通工具。对于三个航线，分析飞行剖面，获得传统推进产生的燃料消耗和排放，然后应用可持续替代方案。
