Emissions inspection and maintenance (I/M) programs subject vehicles to periodic inspections of their emission control systems. Despite widespread use of these programs in air-quality management, policy makers and the public have found a number of problems associated with them. Prominent among these issues is the perception that emissions benefits and other impacts of I/M programs have not been evaluated adequately. Evaluating Vehicle Emissions Inspection and Maintenance Programs assesses the effectiveness of these programs for reducing mobile source emissions. In this report, the committee evaluates the differences in the characteristics of motor vehicle emissions in areas with and without I/M programs, identifies criteria and methodologies for their evaluation, and recommends improvements to the programs. Most useful of all, this book will help summarize the observed benefits of these programs and how they can be redirected in the future to increase their effectiveness.

The purpose of this code is to provide guidance to provincial transportation and environmental regulatory agencies regarding light-duty vehicle inspection and maintenance programs as a means of reducing excess exhaust and evaporative emissions of volatile organic compounds, nitrogen oxides, carbon monoxide, and particulate matter from in-use motor vehicles in large urban centres. The code is intended as a basis for implementing consistent and uniform control measures employing the latest technology for the testing of in-use motor vehicles across Canada. Training requirements are included in the code to help maintain efficient inspection station and repair shop operation as well as the health and safety of the motorists who participate in the programs. This document includes an outline of the legislative and policy considerations behind the code, the basic program parameters, and information on test procedures and equipment, quality control and assurance, repair technician and facility certification, and development of public awareness.
