The STM plays a key role with respect to protecting the environment, most notably by helping to remove some 500 000 cars from circulation during rush hour.

Thanks to over a million trips taken each day by its passengers, the STM contributes to reducing greenhouse gas emissions, estimated at more than 430 270 tonnes of CO2 each year, and takes an active part in various programmes related to sustainable development.

In addition to protecting the environment, our clients can save up to $8550 per year¹ by choosing public transportation instead of their cars. The choice is clear !
