Aviation chiefs rejected measures to curb climate impact of jet vapours

Airline industry claimed science not robust' enough to implement new controls to combat climate warming caused by vapour trails

Airlines and airports opposed measures to combat global warming caused by jet vapour trails that evidence suggests account for more than half of the aviation industry's climate impact, new documents reveal.

The industry argued in government submissions that the science was not robust" enough to justify reduction targets for these non-CO₂ emissions. Scientists say the climate impact of vapour trails, or contrails, has been known for more than two decades, with one accusing the industry of a typical climate denialist strategy".
