According to a comprehensive modeling study, the climate benefits of contrail avoidance depend on speed, not perfection ...

Most of us first spot them as children—the white lines in the blue sky that are the telltale sign of a flight overhead. Contrails are an instant visual reminder of air travel, and a source of much ...

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 ...

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.

Analysis of in-flight emissions from an Airbus A350-900 using 100% sustainable aviation fuel indicates a reduction of 35% in soot particle numbers, and a halving of contrail ice-crystal formation per ...

ALBANY, N.Y. (Dec. 4, 2025) — If you look up at the sky on a clear day, chances are you’ll notice thin, white clouds following behind airplanes— also known as contrails. The formation of these wispy ...

Aviation’s climate impact extends beyond carbon dioxide emissions. A new study from Chalmers University of Technology and the University of Gothenburg, Sweden, and Imperial College, UK, reveals that ...

Assuming that the radiative forcing impact of aviation-induced contrails is sufficiently strong to justify mitigation measures, it is likely that operational strategies that avoid flying through ...
