Biking for the Planet
To limit the negative impacts of global warming as much as possible, Quebec has the objective of being carbon neutral by 2050. To do so, biking, and active transportation in general, is amongst the most efficient, sustainable and simple solutions to implement at a larger scale.
The Impacts of Climate Change are Already Here
Across the planet, the impacts of climate change are felt more and more.
Since the 1980’s, floods, snowstorms, wildfires and heat waves are increasing in intensity and will be more frequent in the upcoming decades.
To minimize as much as possible the negative impacts of global warming, governments around the world have committed themselves to reduce their greenhouse gas emissions. Quebec thus aims to decrease its emissions by 37.5 % compared to 1990 levels by 2030 and to achieve carbon neutrality by 2050.
Biking, an Alternative to the Most Polluting Trips
Because of cold starts, frequent stops, low-speed driving and congestion, short trips by motorized vehicles are the ones emitting the most greenhouse gases (GHGs). Luckily, these are the easiest to replace by biking, conferring biking its tremendous potential to reduce the carbon footprint of the transportation sector.
Reduction of GHG Emissions Already Observed in Montreal
- 1.7%
from the increase of cyclists and biking network between 2008 and 2014
Potential Reduction of GHG Emissions in Montreal
- 12%
if car trips of less than 10 km were made by bike (32 % of current trips).
Potential Reduction of GHG Emissions in Quebec
- 8%
if car commuting trips of less than 10 km were made by bike.

Indirect Environmental Benefits of Biking
Beyond reducing greenhouse gases (GHGs) of daily trips, bike usage also has positive impacts on the spatial organization of cities and mobility, which amplifies efforts to reduce emissions.
Biking reduces, and sometimes eliminates, certain high emissions infrastructures and the carbon footprint related to their maintenance (ex.: parking, urban highways). This is also an opportunity to dedicate the space they occupy for greening, which contributes to reduce the urban heat island effect and allows more equitable land management opportunities.
Combined with public transit, biking (with a personal bike or bikeshare) can replace long distance trips that would usually be done by car. This combination can reduce even more GHG emissions. So, to pursue our climate objectives, it is important to integrate our biking networks and public transit infrastructures.
