German researchers say aviation biofuel can reduce negative climate impacts of flying

In Germany, researchers at the German Aerospace Center say the use of aviation biofuels can reduce soot emissions and contrail formations. By blending 50% biofuel, soot-related ice crystal formation can but cut by 80% while contrail formation can halve. They argue that by reducing the amount of clouds created by aviation can help to reduce negative aviation-induced climate impacts. The German Aerospace Center and NASA are currently undertaking joint missions to investigate different fuel blends on soot emissions and contrails.
