A new study suggests that adding a tiny amount of ice-nucleating particles into aircraft engine exhaust could make contrails far less harmful by shortening their lifespan.

Aviation contrails cost over 4 billion annually in climate damage, rivaling CO₂ emissions. 2-3% of flights cause 80% of ...

Most airplane contrails go unseen from space, yet they may drive much of aviation’s climate impact, according to new MIT ...

Adam Durant ’06 ’07 joins physics professor Raymond Shaw to discuss green aviation and how updating flight plans to prevent long-lasting contrails can reduce climate impacts. It’s not rocket science.

Contrary to what some people seem to believe, contrails are not a way for the evil governments of the world use to poison us. They can, however, be harmful to the environment, with some studies ...

Aviation’s climate impact extends beyond carbon dioxide emissions. A new study from Chalmers University of Technology and the ...

Researchers at the Institute for Meteorology at Leipzig University have, for the first time, determined the climatic impact of contrails that form within natural cirrus clouds. Contrails account for ...

IN THE SKIES OVER MONTANA ― It was a six hour flight that officially didn't go anywhere, but could help usher in a new chapter of aviation sustainability. A high altitude series of science experiments ...

If you look up in the sky during a sunny day, you might see long, skinny looking clouds coming from behind planes. Those are contrails, short for ‘condensation trails.’ Airplane engines produce them ...

Research says aircraft burning a 50/50 sustainable aviation fuel (SAF) blend produce 50 to 70 percent fewer ice crystal contrails at cruising altitude. Using a 50/50 sustainable fuel blend can reduce ...

KAILUA-KONA A line-shaped cloud that stretched over West Hawaii shortly after 9 a.m. Wednesday appears to have been a contrail from a plane, meteorologists say. “I just noticed something coming from ...
