How do we calculate that Travelling by public transit emits 20 times less CO2 than travelling by car? March 14, 2011
The calculation used to arrive at this result is based on several factors.
1. The Origin-Destination study conducted in 2008 enabled us to determine that the average distance travelled during a trip on the STM network is 8.3 km, of which 5.3 km occurs on the métro. We also learned that the average number of passengers in a car is 1.3.
2. Our calculations are based on a rush hour scenario with an average of 65 passengers per bus. We can then calculate the CO2 emissions from the bus divided by 65 to obtain the emissions per passenger-km. As for the métro segment, we know that the métro emits no CO2, as it is 100% electric.
3. We then compare the emissions for the same 8.3-km trip carried out by a car with 1.3 passengers.

In an effort to provide you with even more service when using the bus network and make your life easier, the STM offers high-frequency bus service on 31 of its bus routes.
The 10 minutes MAX network means:
- A bus every 10 minutes maximum from 6 a.m. to 9 p.m. weekdays on 31 bus routes
- A greater frequency of bus service in areas without métro service
- A transfer point with at least one métro station
- A walking distance of less than 1 km
- A rapid network accessible to 568 000 clients
- 50 articulated buses flying the network’s own colours
The STM is currently consolidating its bus services into groups, known as families, based on the type of service, such as local bus routes, express lines, night time routes, those dedicated to specific clients and the 31 lines making up the backbone of the 10 minutes MAX network.
