YUL Montréal-Trudeau Airport has joined an initiative launched by Tourisme Montréal called “Sustainable way”.
You can calculate the carbon footprint of your stay and offset it with a donation if you wish. For more information: https://www.mtl.org/en/explore/visit-montreal-sustainable-way#calculator.
Many airlines are also offering to offset the emissions from your flight or purchase eco-fuel. Ask your airline for more information.
Here are some tips to reduce your GHG emissions
Compare not only the price and time of flight options, but also the GHGs emitted by the different routes offered
Reduce energy consumption in your home while you are away: Turn off the air conditioning or lower the heat, unplug your electrical appliances (computers, television, etc.), turn off the lights or use a timer.
Travel light by limiting the weight of your baggage: Baggage weight affects the fuel consumption of aircraft and therefore the greenhouse gas emissions of your flight.
