Although these non-CO2 effects account for about 2/3 of aviation's total climate impact, they have not been regulated in the past.This report summarizes the most important decision parameters that need to be considered by policy-makers for the implementation of a Monitoring, Reporting and Verification (MRV) framework for non-CO2 effects of aviation. Many of the considerations are also reflected in the MRV framework of the EU Emissions Trading System, which will enter into force on 1 January 2025.20enghttp://rightsstatements.org/vocab/InC/1.0/aviationClimate impactnon-CO2 effectscontrailsEU ETSTransport
