Aviation Emissions and evaluation of Reduction Options Modelling System

The AERO-MS is a tool owned by the European Union Aviation Safety Agency and has been developed specifically to support impact assessments for regulations to reduce greenhouse gas (GHG) emissions from aviation. The AERO-MS assesses the economic and environmental impacts of a wide range of policy options to reduce international and domestic aviation GHG emissions. Policy options that can be examined include the different taxation (including fuel and ticket taxation), emission trading schemes (such as the EU ETS) and offset schemes like CORSIA, the introduction of sustainable aviation fuels and air traffic management (ATM) improvements. Such policy options, the model shows, can affect both the supply side and demand side of the air transport sector. The AERO-MS forecasts the impact on emission reductions of measures and policies but also the extent by which demand for air travel is reduced due to these higher prices.

AERO-MS has formed a key part of about 40 international studies where the model results have provided a quantified basis for policy judgement. Recently AERO-MS was applied for the European Aviation Environmental Report. Also, AERO-MS has been applied in various impact assessment studies for the European Commissions, also with respect to the inclusion of aviation in the EU ETS. In 2019 the model was used for the evaluation of the air service regulation . Further studies, in which the AERO-MS was applied, were executed for a range of other clients like EASA, IATA, ICAO, Airbus, and national governments (Germany, UK, the Netherlands).
