Use of Alternative Transportation Fuels and Its Environmental Implications in Canada

Motor vehicles using gasoline and diesel fuel are major contributors to atmospheric pollution. There are several alternative fuels that are potentially cleaner than current gasoline and diesel fuel. Exhaust emission measurements of regulated and non-regulated pollutants using a number of alternative fuels including low level alcohol-gasoline blends, natural gas, propane, and methanol in selected vehicles show certain environmental/air quality benefits and indicate future potential to further reduce the motor vehicle emissions.
