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. Halving the ice particles that form in the contrail decreases the climate-warming effect of the contrail cirrus by 20%; the effect is halved if there are 80% fewer ice crystals, according to a study conducted by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).

Researchers at MIT have determined that growth in aviation causes twice as much damage to air quality as to the climate. In an open-access paper in the journal Environmental Research Letters , they examine how this damage can be mitigated, and provide consistent comparative assessments of aviation emissions trade-offs, considering both climate and air quality impacts. Aviation emissions are an increasingly significant contributor to anthropogenic climate change.
