Greenhouse gas (GHG) emissions

According to the UN World Tourism Organization (UNWTO), greenhouse gas (GHG) emissions are a factor in the rise in average temperatures worldwide. Because tourist activity is thought to account for 5% of GHG emissions globally, Transat believes that it must act responsibly to reduce its carbon footprint.

Renew our fleet

  • In 2019, Air Transat began the renewal of its fleet with the arrival of its first Airbus A321neoLR. The Airbus A321neoLR is in perfect sync with Air Transat’s continued efforts in sustainable tourism.

Develop a clean and sustainable fuel

  • Air Transat, member of SAF+ CONSORTIUM, finalist to develop sustainable fuel: its clean fuel production technology will revolutionize the aviation industry.

Strengthen our fuel savings program

  • As Canada's leading holiday airline, Air Transat flies millions of people to beautiful vacation destinations every year. These operations result in GHG emissions. Although air transportation accounts for only 2% of worldwide GHG emissions, Air Transat believes that everyone must do their part to combat climate change and support airline industry standards and goals established by IATA and ICAO. To that end, in 2004 it instituted a fuel management program, which has since become one of the most innovative and rigorous in the industry.

Program objective

The program, in which all Air Transat operating departments are closely involved, aims at improving fuel performance and reducing greenhouse gas (GHG) emissions. The main initiatives that our dedicated teams have implemented are as follows.

Flight Operations

The most keys to improved fuel efficiency are the flight plan, piloting, and aircraft weight reduction. Measures successfully implemented by Flight Operations have had a direct effect on those three factors.

  • Sophisticated flight-planning software has been installed, optimizing fuel burn for a flight based on factors such as weather, traffic, winds, etc.

  • A software tool (AVIASO) that enables detailed tracking and analysis of fuel consumption has been implemented.

  • Flight procedures have been optimized for our pilots (flap settings, optimized climb, re-clear, reduced landing thrust, etc.).

  • Cost indexing is used to determine the most economical speed for aircraft on specific routes.

  • Pilots receive comprehensive fuel-efficiency training.

  • Pilots now use electronic flight bags (EFBs), reducing the amount of manuals carried on board.

Ground Operations

Airplanes do not just burn fuel during flight. They also consume a lot of fuel while on the ground at airports before takeoff and after landing. Air Transat has taken steps to address this issue:

  • Air Transat pilots taxi on a single engine to and from the runway.

  • Auxiliary power unit (APU) use is minimized while aircraft are at the gate by the use of electric ground power units (GPUs). This also reduces noise pollution.

  • Cargo and baggage loading has been improved so as to optimize aircraft centre of gravity.

  • Lighter-weight baggage and cargo containers are used.

Technical Operations

Aircraft maintenance also has an influence on fuel consumption. Technical Operations has developed several procedures designed to improve fuel efficiency:

  • All aircraft are fitted with wingtip devices to reduce vortices that increase drag. Four of our B737s have split scimitar winglet systems, which offer a further increase in fuel efficiency of nearly 1%.

  • Aircraft are regularly washed to remove dirt and grime, which increase drag.

  • An inspection program has been implemented that identifies and repairs factors that increase drag (e.g., chipped paint).

  • Engines are washed internally several times per year to remove contaminants that reduce fuel efficiency.

  • Engineering uses materials and on board components that are as light as possible.

Inflight Services

The main contribution of Inflight Services to fuel efficiency is weight reduction. This is achieved in several ways:

  • Catering weight is kept to a minimum through use of lightweight products wherever possible (e.g., plastic bottles instead of glass).

  • The amount of inflight service items has been reduced (optimized catering provisioning, elimination/reduction of certain items and packaging).

  • The amount of drinking water carried on board has been optimized.

  • Flight attendants use mobile devices, reducing the amount of paper manuals on board.

CO₂ emissions from Air Transat flights


Total CO₂ emissions

Fuel consumption (litres) / CO₂ emissions (kg)
(per passenger/100 km)



3.15 L – 7.97 kg



3.18 L – 8.05 kg



2.89 L – 7.31 kg



2.95 L – 7.46 kg



2.98 L – 7.54 kg



2.99 L – 7.56 kg



2.87 L – 7.26 kg



3.07 L – 7.76 kg



3.07 L – 7.76 kg



3.1 L – 7.83 kg



3.15 L – 7.97 kg



3.30 L – 8.35 kg



3.28 L – 8.30 kg



3.26 L – 8.25 kg

Note: Total CO₂ emissions are directly related to number of flights made; with the exception of 2010, our Flight Operations have grown year over year.

CO₂ emissions per passenger

Calculating GHG emissions

Individual passengers can estimate the quantity of carbon emissions they generate every time they fly using the International Civil Aviation Organization’s Carbon Emissions Calculator (ICAO), which uses a proven calculation methodology. Go ahead and use this tool: it’s simple! Following are some sample trips.

Offsetting GHG emissions

As a traveller, you can offset your emissions by purchasing carbon credits. To make an informed choice, you’ll need to consider a number of factors: the credibility and transparency of the organization that provides the offsetting service, the nature and quality of the projects in question (look for benefits that are permanent and attributable essentially to the initiatives funded), external audits, etc. Find out more to be sure you’ll be purchasing credits that truly make a difference!

Our fuel management initiatives

Our fuel management initiatives

Discover Air Transat’s initiatives to reduce greenhouse gas emissions. Our fuel management program is acknowledged as a model in our industry and stands out for the measures it implements prior to takeoff, during and after the flight, with the cooperation of all employees.

Encourage our employees to use sustainable transportation

If every one of our 5,000 employees in Canada adopts sustainable transportation for their commute or limits their travel by automobile, the resulting reduction in emissions will be significant. Since 2010, more than 500 employees each year have taken part in our public transit incentive program.

  • ​​

  • To increase the rate of participation in its sustainable transportation programs, Transat seeks to implement new measures.

  • ​​

  • To engage more employees, Transat seeks to maintain and promote the sustainable transportation programs it makes available to Canadian personnel (OPUS, Green Commute) and in turn curb GHG emissions related to their commutes.

  • Transat raises awareness among employees by encouraging them to take part in the Défi sans auto solo day in Montreal and Bike to Work Day in Toronto.

  • Since 2015, Air Transat has made free electric-vehicle charging stations available to employees and has reserved nearly 15% of its parking spaces for low-emission and ride-share vehicles.

Reduce our business-travel-related GHG emissions

  • To reduce GHG emissions generated by its business travel, Transat must gauge the global impact of that type of travel and raise employees’ awareness.

  • In order to reduce business travel, Transat wants to conduct an awareness campaign aimed at its managers.

  • To measure and in turn reduce emissions, in 2016 Transat implemented a management system to monitor them.

  • Objectives related to the ongoing Travelife certification process. For complete details about this certification being sought by Transat, go here.

  • Objectives related to the various environmental certifications achieved by Air Transat.
