Since COVID-19 resulted in a global collapse of air travel, the airline industry and its lobby has been working to get back on its previous growth path. In response to rising public and political awareness of the climate-damaging effects of air travel, the industry is doing a lot of communication around "green" flying through new technologies. The organization Stay Grounded has taken a critical look at the industry's claims and published five fact sheets on topics such as: efficiency, electric flights, hydrogen, biofuels, and E-fuels.
With its factsheets, the organization is doing important information work. Technological change must come, but it will not be fast enough. So additionally, a reduction in air traffic is necessary.
