CONCERTO aims to provide the means to maximize the opportunities for CO2 reduction and to introduce non-CO2 impact management in daily operations. The goal is to reach TRL6 processes and tools that allow the ecosystem to achieve more eco-friendly trajectories and thus higher climate impact reduction without requiring major changes on legacy ATM and airlines systems. To do so, two specific objectives are declined for CONCERTO. The first one focuses on CO2 emissions reduction when the second one introduces non-CO2 climate impact reduction mitigation means. Finally, as CONCERTO is a data driven project, generating data on CO2 and non-CO2 effects and opportunities at TMA, ATSU and possibly network level, the project presents the opportunity to contribute to the improvement of european environmental performances dashboards. Ambition #1- Keep the pace on CO2 emissions reduction, integrate Green ATC capacity in ATM processes, with the appropriate level of automation, and support ATM actors in balancing permanently regularity and environmental performance at local and network level. Ambition #2- By leveraging state-of-the-art climate science, allow ATM actors to take their “eco-responsibility” to the next level Ambition #3- Strengthen cooperation, anticipation and exchange of information between NM, Air Traffic Control, Airlines and Flight Planning Service providers. Ambition #4- Demonstrate that mitigation measures such as the eco-friendly orchestrator and ECHO area avoidance concepts can be deployed progressively at network level, in close connection with scientific progress
