Grenelle Law

France’s Grenelle Law applies to all transport services which originate or terminate at a French airport. The law requires transport companies to inform the beneficiaries of their services of the CO2 emissions related to their travel.

In accordance with the Grenelle Law, Air Canada is providing CO2 emissions information for select flights originating or terminating at a French airport. For any questions on the application of the Grenelle Law with respect to Air Canada, please write to

Please note that the CO2 emissions information Air Canada provides represents an estimate, is to be used for information purposes only, and is based on the following:

  • Flights are direct or include one stop with transit points in Montreal or Toronto; flights with multiple transit points are not shown.
  • Flights are one way.
  • Flights are operated by Air Canada or Air Canada Express; codeshare flights are not included.
  • Calculations are based on information from the online calculator of France’s Directorate General of Civil Aviation (DGAC), as directed by Grenelle Law guidance material; Air Canada assumes no liability for the accuracy of the information or methodology used to estimate CO2 emissions.
  • Estimates are presented in kg of CO2 per passenger.
  • A Boeing 77W aircraft is used for calculation of the transatlantic portion of the journey.

An Airbus 319 aircraft is used for calculation of the Fort-de-France – Montreal and Pointe-à-Pitre – Montreal portions of the journey.
