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. —Ulrike Burkhardt.

Green NCAP LCA study shows detrimental climate and energy impact of increasing vehicle weight, including EVs

Green Car Congress

The results of the Life Cycle Assessment (LCA) of greenhouse gas emissions and primary energy demand of the cars tested by Green NCAP in 2022 show that the current and continuous trend towards larger and heavier cars, significantly increases the negative impact on climate and energy demand.

NASA and DLR to conduct joint flight tests on alternative fuel emissions with focus on ice crystals

Green Car Congress

The focus will be on alternative fuel emissions and the characterisation of ice crystals in condensation trails (contrails), using biofuel as an example. The planned research flights are intended to determine particle emissions and how they affect cloud formation through contrails, thus investigating their impact on the climate.
