Eyes on the future
Advancing our sustainability journey
— In 2024, we took steps to further embed sustainability in our decision-making. We continued to track metrics in waste, water, energy and emissions. We also began the important work of reviewing and updating our sustainability strategy to ensure alignment with our updated corporate strategy.
2024 sustainability highlights
Installed more than 8,300 LED fixtures to improve guests’ experience and saved 540 tCO2e/year.
Developed a drought and water-shortage plan that allows us to use stormwater in place of treated water in certain cases, including construction. On the West Runway Rehabilitation project alone we saved 15% of total potable water requirements.
Advanced our zero-waste strategy by assessing wastehandling processes and creating a road map to diverting up to 90% of our waste.
Successfully piloted AI-assisted waste-sorting stations and identified opportunities to immediately divert up to 66% of terminal waste.
Emissions
In 2024 overall emissions were 3.7% higher compared to 2023. Natural gas consumption was up in 2024, driven largely by differences in weather which caused our HVAC systems to cycle more frequently. Heating requirements were 9.2% higher in 2024 compared to 2023.

Water
Potable water use continued to decline, both overall and on a per passenger basis. This was partly due to water conservation measures prompted by the City of Calgary’s water supply emergency in the spring and summer.
2024 vs. 2023
In 2024, potable water use from meters associated with The Authority’s end-uses was on par with 2023. In line with our sustainability objectives, The Authority developed a water trailer prototype in response to water restrictions implemented by the City of Calgary. During restrictions and for the remainder of the summer, stormwater was used in place of potable water from the City and successfully delivered approximately 5,000 liters of water for irrigation.
Waste
Waste diversion trends saw a significant improvement in 2024 compared to 2023.
