STM - Society in motion
Our public consultation to find a name for Montréal’s future métro cars has ended Monday, April 11, 2011, at 4 p.m.
THANK YOU TO ALL WHO PARTICIPATED.
A selection committee will review all of the proposals that were sent in and choose a few finalists.
A second round of consultations will be held to determine the overall favourite name.
Stay posted !
DO YOU HAVE AN IDEA FOR A NAME FOR THE NEW MÉTRO CARS?
AS OF MONDAY, MARCH 28, SUBMIT YOUR SUGGESTION
As announced during the unveiling of the exterior look of the new métro cars, the STM is holding a public consultation from Monday, March 28 to April 11 to find a name for the new métro cars. The STM is calling on your creativity to come up with an idea and submit it in this page….
How do we calculate that a return trip by public transit rather than by car has the same ecological benefit as a tree over a year? 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 take into account the total GHG emissions of STM buses divided by the actual ridership on the bus network, for an average of 112 g of CO2 per passenger-kilometre for the buses. We then calculate the emissions for an average trip of 3 km by bus (at 112 g per passenger-km) and 5.3 km by métro (the métro segment emits no CO2, as the métro is 100% electric).
3. As for a trip by car in the city, it generates 208 g of CO2 per passenger-kilometre, or 270 g per kilometre /1.3 passenger.
4. We then compare the emissions from the same 8.3-km trip carried out by a car with 1.3 passengers and carried out by bus and métro. This calculation determines that each return trip prevents net CO2 emissions of 2.8 kg.
5. The quantity of CO2 stored by a tree in a year varies depending on the type of tree and the type of environment. In order to establish the equivalence in terms of CO2 between a trip by public transit and a tree, we used calculators from TreeCanada and ZéroCO2. Research carried out by the team of Claude Villeneuve at Université du Québec à Chicoutimi provides similar indications. On the basis of this information, we concluded that a tree stores on average 2.8 kg of CO2 per year.
6. Obviously, trees, just like public transit, offer many other ecological benefits in addition to the reduction of CO2 !
