Alternative fuels have the potential to support the environment- and climate-friendly developments in air transport. At present, global air traffic contributes towards almost five percent of global warming. In addition to the greenhouse gas carbon dioxide, condensation trails and the resulting cirrus clouds lead to a significant climate impact. In a three-week series of flight tests lasting until 9 October 2015, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is investigating how to reduce the impact of air transport on the climate by using alternative fuels. A possible reduction in carbon particulate emissions – and with this a change in the properties of condensation trails – plays an important role.
