  • Develop testing and evaluation procedures for vehicles, engines, emission control components, fuel additives and test equipment to ensure that emission standards are met.
  • Conduct information and training seminars for vehicle dealers, mechanics, inspectors and members of the public on vehicle emissions and resulting air pollution.
  • Develop measures for reducing greenhouse gas emissions from mobile and other sources as required by the California Global Warming Solutions Act of 2006.
