- Nanoparticles from the exhaust of a jet engine function as cloud condensation nuclei (CCN) in the atmosphere.
- A baggage handler inhales roughly 240 billion nanoparticles each day they work at Copenhagen Airport.
- Sulphate injections are one of several "geoengineering" solutions to climate change being discussed by scientists. The data published in "Science" magazine suggests that this strategy would lead to a drastic thinning of the ozone layer.
- Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth's surface.
- Jet fuel contains high concentrations of sulphur - about 1000 ppm. In comparison, the sulphur content in diesel fuel is 10 ppm, ie. approx. 100 times lower than that in jet fuel.
- Aerosols created by flight pollution act as cloud condensation nuclei (CCN), which create clouds.
- The Civil Aviation Organisation statistics show that were 30,303,519 carrier departures worldwide in 2012. There were also millions of unregistered military aircraft departures.
- Aircraft engines are believed to be a key source of inorganic sulphate particles and SO2 due to the high sulphur content in jet fuel.
