D2.4 – Report on the climate impact of the second set of operational improvement options

D2.4 presents the results of the second iteration of the assessment of the selected operational improvements (OIs). The second assessment focuses on the same nine OIs as the first one. Such OIs cover three different categories: network-related OIs (two OIs), trajectory-related OIs (three OIs), and ground-related OIs (three OIs). In addition, three scenarios, combining different OIs within the category, are presented. These scenarios are aimed to highlight the synergies between different OIs. The assessments presented in this deliverable include both climate and non-climate KPIs.
