Greg Rideout

Engineer - Head, Toxic Emissions Research and Field Studies, Emissions Research and Measurement Division

Current research and/or projects

Assessing risks to Canadians and their environment posed by pollutants or other harmful or dangerous substances, conducting S&T in support of the development of regulations, codes of practice, guidelines as well as associated enforcement activities related to waste management, product control, effluent and emissions

  • Characterizing emissions from alternative, reformulated, and future fuels for light and heavy duty vehicles
  • Characterizing the emissions and performance of vehicles utilizing fuel cells, electric, and diesel-electric hybrids, in both the light and heavy duty sectors
  • Exhaust emission characterization of non-road sources such as utility engines, locomotives, marine vessels, and construction equipment
  • Developing exhaust after-treatment technologies for heavy duty diesel vehicles both on and off-road
  • Advance propulsion systems and emerging transportation systems

Professional activities / interests

Sampling and analysis of toxic air emissions from mobile sources

Impacts of fuels and emission control technologies on emissions

Vehicle emission control strategies

Managed several international programs whose focus has been the development of effective emission control strategies for mobile sources; working closely with government and industry counterparts in other countries.
