In addition to CO2, aviation affects the climate through other emissions and atmospheric processes, such as the formation of ozone and contrail cirrus (non-CO2 effects). Although non-CO2 effects are responsible for about 2/3 of the climate impact of aviation, they are not yet considered in the EU ETS and under CORSIA.
This project focuses on the development of concepts for the integration of non-CO2 effects of aviation into such schemes and discusses the current state of scientific knowledge, the availability of necessary data from the airlines and data verification by the administrative authorities. It concludes that the inclusion of non-CO2 effects in these schemes is technically feasible.
