This paper outlines the results of a remote sensing measurement programme undertaken in Auckland with Auckland Regional Council in April/May 2003 to measure exhaust emissions of a large number of motor vehicles. The study measured tailpipe emissions from over 40,000 vehicles at 15 sites across the Auckland region. This paper presents the results and analysis of the emissions for a subset of 15,000 vehicles and focuses on carbon monoxide (CO) emissions. CO was chosen as it is a good indicator of the state of tune of the vehicles. The full analysis for all valid readings and all contaminants is currently pending and will be released later this year but preliminary processing indicates that the conclusions presented here are unlikely to be altered substantially. The data provide a baseline for emissions performance of the fleet so that the effectiveness of proposed policies to reduce vehicle emissions can be assessed. The data are also being used to raise public awareness about vehicle emissions and the need for vehicle maintenance.
