Route sustainability

By optimizing routes, we promote the reduction of aircraft fuel consumption and emissions and lead the way with our contribution to "Climate Action" (SDG No. 13)


Flight Efficiency Plan (FEP)

Developed in the last decade, the Flight Efficiency Plan is a multi-year plan of measures that form part of the EU’s Single European Sky programme. It seeks to create an airspace structure that optimizes the aviation network. The objective of the FEP is to contribute to the reduction of customer management costs and environmental impact and to introduce a cutting-edge navigation system in Italian airspace.


  • increasingly efficient flight profiles;
  • direct routes with positive effects on costs, consumption and harmful emissions;
  • reduction of flight times with consequent reduction of management costs.

Free Route Airspace Italy (FRAIT)

In December 2016 we implemented Free Route Italy, a revolutionary project that made it possible for all aircraft flying above 9,000 meters to cross Italian skies using a direct route without having to follow a specific network of routes.
Thanks to FRAIT, in 2017, it was possible to generate annual savings of approximately 30 million kg of fuel, equal to the avoidance of about 95 million kg of CO₂ emissions. The performance obtained in 2018 was even better: thanks to the more efficient routes that airlines could use, the distances travelled by aircraft decreased by 11 million km, with a consequent reduction of 43 million kg of fuel and the avoidance of about 135 million kg of CO₂ emissions. In 2019, the reduction in flight distances was 14 million km, with a consequent decrease of approximately 53 million kg of fuel and a reduction of 167 million kg in CO₂ emissions. As for 2020, the consequences of the COVID-19 pandemic emergency and the extraordinary reduction in air transport activities also affected the results monitored with the FEP. Last year, the reduction of in route distances came to 7 million km, with a consequent decrease of about 29 million kg of fuel and the avoidance of about 91 million kg of CO₂ emissions. The total reduction in distances travelled by aircraft between 2016 and 2020 was 43 million km, with a consequent decrease of about 156 million kg of fuel and the avoidance of 492 million kg of CO₂ emissions.


  • fuel savings;
  • reduction of harmful emissions and costs;
  • maintenance of unchanged safety levels.

Airport Collaborative Decision Making (A-CDM)

Airport Collaborative Decision Making (A-CDM) is an operating procedure developed and implemented with the airport operators. It is intended to reduce the taxiing times of aircraft before take-off and ease the congestion of aprons and taxiways. Compared with the past, the procedure allows the aircraft to avoid long waits with their engines running before take-off. Controllers can tell pilots to start up their engines and move from the gate only when they is sure that the path to take-off is free of obstacles. At the Rome Fiumicino airport alone, the A-CDM procedure enabled a reduction of up to 800 taxi minutes every day, the equivalent of a reduction of about 10,000 kg of fuel, with the consequent avoidance of 30,000 kg per day of CO₂ emissions. In the last 6 years, therefore, the Fiumicino area has benefited from a reduction of about 65 million kg in CO₂ emissions.
After the Rome Fiumicino airport, the project was launched in the A-CDM airports of Milan Malpensa, Venice Tessera, Milan Linate and Naples.
