7 Projects to reduce CO2 emissions


Air France is taking an active part in seven projects which aim to illustrate that improved cooperation between airlines, aircraft manufacturers and air traffic control services helps to reduce fuel consumption and, as a result, greenhouse gas emissions.


These projects which involve several participants have been chosen by the SESAR-JU, a public /private sector partnership whose aim is to modernize the European system.


The seven projects, which will start this autumn, consist in implementing procedures in coordination with all project participants which improve aircraft energy efficiency during the various flight phases. The following are examples of these projects:


Green flight by A380 from New York-JFK to Paris-CDG: reduction in fuel consumption during the taxiing phase at New York-JFK, optimized flight path and cruising level over the sea in the regions of Gander (Canada) and Shanwick (UK).

  • Participants: Airbus, Air France, National Air Traffic Services (NATS), NAV Canada and the Federal Aviation Administration (FAA);
  • Expected reduction: 3 tons of CO2 per flight.


Green La Navette flights: continuous descent with Airbus A320 at Toulouse and Paris-Orly, cruising level optimized from Toulouse to Paris-Orly.

  • Participants: French Air Navigation Services (DSNA), Air France and Airbus;
  • Expected reduction: 1.5 tons of CO2 per return flight.


Green flights from Paris-Orly to Pointe à Pitre with Boeing 777-300ER: optimized flight path and cruising level over the sea in the regions of Santa Maria (Portugal) and New York (US), continuous descent at Pointe à Pitre.

  • Participants: Air France, DSNA, NATS, NAV Portugal, Adacel and the FAA;
  • Expected reduction: 3 tons of CO2 per flight.


“Green corridor”: optimized flight path and cruising level over the sea in the regions of Gander (Canada) and Shanwick (UK).

aircraft: long-haul aircraft, Airbus A330/A340, A380, Boeing 747-400 and 777;

  • Participants: NAV Canada, NATS and Air France ;
  • Expected reduction: 1 ton of CO2.


Other projects include a reduction in waiting time before take-off for aircraft at Paris-Charles de Gaulle and reducing flight levels on approach to landing.


On 6 April 2010, Air France operated its first transatlantic green flight from Paris-CDG to Miami by 747-400, in an aim to reduce gas and noise emissions, in coordination with the Paris Airports Authority, DSNA, NAV Portugal, the FAA and the SJU.


All these actions are implemented as part of the AIRE program (Atlantic Interoperability Initiative to Reduce Emissions), a joint initiative between the European Commission and the FAA, managed by SESAR-JU on the European side. Within the framework of this initiative, airlines, air traffic control services, aircraft manufacturers and airports are invited to take advantage of current technological achievements in the field of avionics and air traffic and to unite their efforts to operate optimized flights. These flights will validate technical solutions to reduce CO2 emissions.
