We will continue to build partnerships, develop our knowledge, and contribute to sustainability within the aviation industry.

Our GHG Emissions

Our emission factors report on a wider set of metrics within our operational boundaries and strengthened our GHG reporting to encompass all six greenhouse gas types covered by the Kyoto Protocol (expressed as CO2 equivalents, or CO2e):

  • Carbon Dioxide (CO2)
  • Methane (CH4)
  • Nitrous Oxide (N2O)
  • Hydrofluorocarbons (HFCs)
  • Perfluorocarbons (PFCs)
  • Sulphurhexafluoride (SF6)

We expect to make further refinements to our methodology as the aviation industry works toward a harmonized set of reporting standards. We are committed to the industry’s goals of reporting standardization, accuracy, and comprehensiveness.

On December 6, 2024, Chorus completed the sale of its Regional Aircraft Leasing segment, including Falko Regional Aircraft (“Falko”).  As a result, we no longer have access to Falko’s GHG emissions data and have not included these calculations in our 2024 reporting. The reduction in CO2 emissions recorded reflects the removal of the Falko emissions. The 2023 and 2022 Scope 3 data for managed aircraft and and most of the owned aircraft (excluding Voyageur’s fleet) reflected the emissions from aircraft that were managed by Falko, not wholly or majority owned by Chorus, and were leased to third parties.


Infographic showing the breakdown of total greenhouse gas emissions by scope. A pie chart indicates that 98.4% of emissions are Scope 1, 0.3% are Scope 2, and 1.4% are Scope 3. Text states that total emissions across Scopes 1, 2 and 3 are 1,131,761 metric tons of carbon dioxide equivalent (CO2e). Scope 1 emissions are primarily from aircraft fuel (88.8%). Scope 2 emissions are entirely from purchased electricity. Scope 3 emissions are entirely from leased aircraft fuel. A highlighted callout notes that 99% of the organization's total carbon footprint comes from jet fuel.

Scope 1 –

Most of Chorus’ Scope 1 emissions are direct emissions from jet fuel consumed in the course of aircraft operations, with a small percentage from gasoline or diesel consumed by our ground support vehicles and equipment and natural gas used to heat and cool the facilities we own or operate.

Scope 2 –

Our Scope 2 GHG emissions are indirect emissions from electricity.

Scope 3 –

Most Scope 3 emissions include all upstream and downstream GHGs outside of our direct control, but within our value chain.


We follow the guidelines described in the GHG Protocol, A Corporate Accounting and Reporting Standard, Revised Edition. We apply an operational control approach to determine the boundary of our GHG inventory. A company has operational control over an operation if the former or one of its subsidiaries has the full authority to introduce and implement its operating policies at the operation. We select emission factors that are appropriate to each location. The global warming potentials of greenhouse gases included in our calculations are based on the Intergovernmental Panel on Climate Change’s Fifth Assessment Report.

Emissions from the use of aviation jet fuel are the most significant emission source in our value chain. Our jet fuel emissions reporting is based on tank-to-wake calculations, which measure the amount of fuel consumed once it has been loaded onto the aircraft.

(2) GSE data doesn’t include fuel that is sourced from other sources (a local gas station) for when vehicles are used for out-of-base work.
(3) The emission factors used in Scope 2 are location-based and specific to the area where the electricity is purchased. Where actual electricity data was not available, we have estimated the emissions based on the occupancy surface by the tenants.
(4) On December 6, 2024, Chorus completed the sale of its Regional Aircraft Leasing segment, including Falko Regional Aircraft (“Falko”). As a result, Falko’s GHG emissions are no longer included in our GHG reporting. The reduction in emissions recorded in 2024 and 2025 reflects the removal of the Falko emissions.
(5) We have not yet been in a position to quantify our Scope 3 emissions beyond leased aircraft fuel, given the complexity of data collection across our value chain.
(6) GHG emissions data is based on best available data at the time of collection.
