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)
PROJECTS TO REDUCE CO₂ EMISSIONS
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. 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. A feature of 2021, on the other hand, was a slight recovery in air traffic, which, with help of the Free Route Italy project, reduced the lengths of legs by about 11 million km. 48 million kg less fuel was used and there were about 152 million Kg CO₂ fewer emissions. The total reduction in distances travelled by aircraft between 2016 and 2020 was 51 million km, with a consequent decrease of about 204 million kg of fuel and the avoidance of 643 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 used in the biggest Italian airports (Rome Fiumicino, Milan Malpensa, Milan Linate, Venice Tessera, Naples Capodichino and Bergamo Orio al Serio) based on cooperation among ENAV, Airport Managers and the Eurocontrol Network Manager Operations Centre (NMOC). The objective of the procedure is to enhance the efficiency and resilience of airport operations by optimising the use of resources through continuous exchanges of information.
Information on departing and arriving flights is exchanged by all the stakeholders involved through the technological platform that supports A-CDM. Basing itself on the information received from airlines, the platform is able to calculate the ideal time at which flights should start their engines in order to find the quickest taxiing route and avoid waits before take-off. With the adoption of A-CDM, at Fiumicino every departing aircraft saves an average of 2 minutes fewer taxiing times, while in other airports, which are less congested and with a less complex airport layout, the average saving is about 40 seconds.
The reduction in taxiing time brings substantial environmental sustainability benefits owing to lower fuel consumption and consequently fewer emissions. At Fiumicino, with this procedure there were about 13,900 tons of CO₂ emissions fewer in 2019. In considering all the airports in which A-CDM is operational, the reduction in emissions is about 22,300 tons of CO₂ a year.
