Air

We’re all breathing the same air, and keeping it clean is a priority for us. Our industry members have made great strides in clean air initiatives:

  1. Today’s transportation fuels are the product of years of continuous improvement by our industry: more efficient vehicle performance; a reduction in the amount of emissions produced by fuels; and lower toxicity of unburned fuel. 
    • Our industry has invested $5-billion to reduce sulphur levels in gasoline by more than 90 percent, and in diesel by 97 percent since 2005. The industry will also be spending an additional $1.2-billion to meet the new Tier 3 low sulphur fuel standards.
    • Smog-forming emissions of a 2005 vehicle (or newer) are 90 percent lower than a 1993 model.
    • 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 83 percent, 76 percent and 63 percent, respectively, compared to 2005.
  2. Canadian refineries have also made impressive improvements in the amount of atmospheric emissions they create: 
    • Sulphur oxide emissions are down 47 percent, since 2002
    • Nitrous oxide emissions have decreased by 41 percent, since 2002
    • Volatile organic compound emissions are down 48 percent, since 2002
    • Benzene emissions are down by 41 percent since 2002
You can find year-by-year vehicle emissions figures here, and a look at refinery emissions and benzene levels below. 
Refinery emissions of benzene are down 41 percent since 2002, contributing to a 83 percent drop in benzene air concentrations between 1991 and 2012, as measured by Environment Canada.
