 the European aviation industry needs to take drastic measures to reduce its climate impacts in order to achieve net zero goals. While focusing solely on flight CO2 emissions may seem like a good idea, it does not account for the majority of the industry's climate impacts. To address this issue, researchers have developed a methodology based on rigorous lifecycle assessments and time-dependent quantifications of non-CO2 climate impacts. They found that electricity-based synthetic jet fuels and direct air carbon capture and storage, DACCS, could potentially allow for climate neutral aviation. However, these methods are only viable if air traffic is reduced significantly or if the industry switches to renewable energy sources. If neither of those options are taken, then the industry will continue to rely heavily on fossil fuels and their associated climate impacts.
