Aviation accounts for 3.5% of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO2, according to a new study by researchers in Europe and the US. The study was published in the journal Atmospheric Environment. In addition to CO2, air traffic causes condensation trails and nitrogen oxide (NOx) emissions from the combustion of the airplane’s fuel. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions.
