DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.
