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”.
