Testing of a verification scheme for integrating non-CO₂ aviation effects into EU ETS

In addition to CO₂, aviation affects the climate through other emissions and atmospheric processes, such as the formation of ozone and contrail cirrus. These non-CO₂ effects account for about 2/3 of aviation's total climate impact but can vary widely from flight to flight. In order to target mitigation measures, it is therefore essential to calculate the climate impact at the level of individual flights.

This project took the perspective of an authority and tested the necessary tasks and available data in order to assess the data reported by an airline. This work has laid the basis for the integration of a Monitoring, Reporting and Verification framework into the European Emissions Trading System.
