Quebec City Jean Lesage International Airport


The Quebec City Jean Lesage International Airport wanted to modernize and electrify the air-conditioning systems used at the airplane loading terminals of the airport which serves 116,038 passengers each year. The air-conditioning of aircraft awaiting departure on the ground is provided by a motor installed in the tail, namely the auxiliary power unit generator. This motor consumes Jet A-1 kerosene from the aircraft fuel tanks.

The Quebec City Airport enlisted the help of Econoler to conduct a third-party verification of the greenhouse gas emission reduction calculations of the provider of the new electric equipment to be installed. This analysis aimed to validate the subsidy amount from a government program called the programme d’aide gouvernementale à l’amélioration de l’efficacité du transport maritime, aérien et ferroviaire (PETMAF) offered by the ministère des Transports du Québec (MTQ or Ministry of Transportation of Quebec).


Econoler based this analysis on Part 2 of the ISO Standard 14064-2:2006: Specifications with guidance at the project level for quantification, monitoring and reporting of greenhouse gas emission reductions or removal enhancements.

More specifically, the mandate included the following tasks:

  • Reviewed the current and replacement air-conditioning systems and their respective technical parameters;
  • Validated the hours of use of the replaced systems;
  • Quantified the GHG emission reductions;
  • Verified and documented the data of the baseline period, calculation hypotheses and results of a quantification verification report in line with ISO Standard 14064, notably the:
    • Project description;
    • Selection and justification of the baseline scenario (equipment hours of use in both heating and cooling modes, equipment output/performance, etc.);
    • Sources, sinks and reservoirs included in the quantification;
    • The GHG emission reductions calculation.
  • Developed a monitoring plan.

Econoler estimated that modernizing and electrifying the air-conditioning systems of the Quebec City Airport will reduce GHG emissions by 4,455 t CO2 eq. per year compared to the baseline scenario. This project also enabled airlines to save up to $100,000 to $300,000 in jet fuel costs per year per aircraft.
