In 2020, after the COVID-19 pandemic had all but halted global air travel, about 50 KLM Royal Dutch Airlines employees began brainstorming big ideas to present to company leadership. One of these Bold Moves initiatives launched this spring. The Sustainable Flight Challenge will have KLM and 15 other carriers all members of the SkyTeam Airline Alliance operate 22 flights with the goal of beating their own personal bests in reducing carbon emissions. They plan to share all data they gather during the flights freely within the aviation industry to drive innovation.
