The proposal is expected to build on and improve an already established reference European toolbox (e.g. developed in retained proposal(s) from HORIZON-CL5-2022-D5-01-14) able to assess the impact of European aviation R&I, which is deployed to perform impact assessments of European relevant aviation R&I actions in Horizon Europe. The European Aviation R&I policy, and aviation policy at large, need a European capability (as open-source as possible) to assess what has been achieved and provide forecast analysis of the expected outcome of technological, operational measures. The toolbox, through its impact assessments, should provide insight that will be used in the communication of the impact and achievements of European, National and private aviation R&I investments.

The toolbox should:

• incorporate methodological, science-based and validated models that can be traced;
• pay particular attention – beyond CO2 emissions – to non-CO2 emissions and climate-sensitive regions as well as address interdependencies (e.g. noise in the airport vicinity);
• integrate and make use of existing toolboxes developed in previous EU R&I Framework Programmes (e.g. TEAM_PLAY, CS2-TE);
• be able to set the level of fidelity for aircraft technologies and air transport system, based on available data;
• be aligned with the methodology, assumptions, criteria, and required data for seamless data exchange with the Clean Aviation and SESAR 3 partnerships. The Commission will further take into consideration other Horizon Europe impact assessments and coordinate it with the Clean Aviation Technical Committee and SESAR 3 Scientific Committee.
