Marc Shapiro is the Director of the Breakthrough Energy Contrails team, one of American’s partners on contrail avoidance. Below, he answers our questions on the science behind contrail avoidance ...

Contrails are clouds made of ice particles, which can be created when airplanes fly through cold, humid air. Persistent contrails are estimated to have a warming climate impact. Flight tests will ...

A new study allays fears that rerouting flights to avoid forming climate-warming contrails could result in inadvertently making climate warming worse. Researchers from Sorbonne Universite and the ...

IATA has called for urgent action to deepen the understanding on the formation and climate impact of aviation contrails. The newly released IATA report Aviation Contrails and their Climate Effect: ...

Advances LiDAR technology for improved contrail analysis Provides insights for development of new aircraft engines Industry actively collaborating to understand contrail science with aim to reduce ...

The International Air Transport Association (IATA) called for urgent action to deepen the understanding on the formation and climate impact of aviation contrails to develop effective mitigation ...

Four research figures show how contrails appear in two satellite views (left) and two photographs taken from the MIT Green Building. Aviation’s climate impact is partly due to contrails — condensation ...

Trailing effect A new study has found clouds left behind by aeroplanes are causing more global warming than the carbon dioxide they release. Condensation trails, also known as contrails, are the white ...

Satavia, a company specializing in the prevention of contrail formation through adapted flight plans, is about to submit a scientific paper for peer review regarding its approach and methods. Such ...

The challenge of addressing aviation’s non-carbon dioxide emissions is receiving greater attention, with the climatic impact associated with tell-tale signs in the sky coming under increased study.
