Several sectors are considered responsible for GHG impacts in Quebec. Some projects can reduce their impacts.
The majority of greenhouse gas emissions come from transportation, energy, waste management, industrial production and agriculture (link to other sections).
According to a report published by the MDDEFP and entitled “Quebec inventory of GHG emissions in 2008 and changes since 1990” (Report of the policy direction of the air quality MDDEP, published in 2010) in 2008, total GHG emissions in Québec amounted to 82.7 Mt. CO2.
Figure: The sectors responsible for greenhouse gas emissions in Quebec (Source : MDDEFP, 2013)
- The transportation sector (road, air, maritime and rail) emits 35.7 Mt. CO2, or 43.5% of GHG emissions in Québec. Transportation by road emits, by itself, 77.8% of emissions from this sector, or 33.7% of total GHG emissions.
- The industrial sector issued in 2008, 24.7 Mt. CO2, or 29.9% of total emissions in Quebec. For this sector, energy consumption accounts for 55.5% of emissions, 43.5% from industrial processes and 1.0%, fugitive emissions and the use of solvents or other.
It should be noted that it is in this sector that are major emitters, or companies subject the regulatory market (more than 25 000 tonnes eq. CO2 per establishment in 2013). However, the number of SMEs (less than 200 employees) working in this sector is also very important.
- Residential, commercial and institutional sectors produced 10.3 Mt. CO2 or 12.5% of total GHG emissions in Québec through heating.
- Agriculture accounts for 6.4 Mt. CO2 or 7.7% of total emissions in Quebec
- Wastes cover 5.0 Mt. CO2 and electricity 0.4 Mt. CO2 is 6.1% and 0.8% of total GHG emissions respectively.
Several projects implemented by the government reduce GHGs in different sectors.
