Since 1992, environmental upgrades in refineries have resulted in water effluents with lower concentrations of five regulated substances: oil and grease, sulphide, ammonia nitrogen, phenol and total suspended solids.
Sulphur levels in gasoline have been reduced by over 90 per cent since 2004.
Smog-forming emissions of a 2005 vehicle (or newer) are 90 percent lower than a comparable 1993 model.
Sulphur levels in diesel have been reduced by 97 per cent since 2004.
Since 2002, sulphur oxide emissions from Canadian refineries are down 54 percent, nitrous oxide emissions have decreased by 44 percent and volatile organic compound emissions are down 52 percent.
Our industry has invested $5-billion to reduce sulphur levels in gasoline and diesel.
Personal and commercial consumption of transportation fuels account for 28 per cent of Canada’s greenhouse gas emissions. The refining industry that produces our transportation fuels accounts for just 2 per cent of Canada’s GHG emissions.
Since 1990, carbon dioxide emissions from the refining industry have decreased by 12 percent.
Environment Canada predicts that by 2030, total Canadian on-road vehicle emissions for nitrous oxide, sulphur dioxide and particulate matter (PM2.5) will drop by 79 percent, 69 percent and 57 percent, respectively, compared to 2005.
