NEW research shows just 20 airports produced the equivalent CO2 emissions of 58 coal plants Launched today, the 2024 ‘Airport Tracker’ – an update to the first global inventory of CO2 and local air pollutants from passenger and freight flights – shows the scale of...
What is the climate impact of aviation?
Stopping the climate crisis is the biggest challenge humanity has ever faced.
It’s about more than just CO2: The total climate impact of aviation
Despite flying being a privileged activity of a global minority, aviation has already contributed about 3.5% of all human-caused global heating to date. That is because planes generate also contrails, induced cloudiness and NOx derivatives, which raise the total climate impact to 3 times that of the CO2 alone. And air transport emissions have been rising fast: in 2018 they accounted for 5.9% of all human-caused global heating. Cutting air traffic reduces non-CO2 climate impacts immediately.
