Abstract: Global warming had been a major cause of concern since the 19th century. Out of the many greenhouse gases, carbon dioxide remains as the greatest contributor of global warming. In recent years many international efforts such as the Kyoto Protocol were made, but had not had much success in bringing down global carbon dioxide levels. In Singapore, five different sectors had been identified as the greatest contributor of carbon dioxide in the country. Out of all five, the transport sector had not seen as much success in carbon dioxide reduction efforts. In an effort to measure the spatial variability of near ground level ambient carbon dioxide concentration with respect to different road conditions, traffic conditions and environmental conditions, field studies were conducted using the National University of Singapore as a case study. Readings were taken at six different locations within the campus over a period of 11 days. The results; while road conditions and traffic conditions were the predominant factor in influencing carbon dioxide levels, the presence of suburban vegetation was able to moderate and lower concentration levels during the day. Locations that induce stop-and-go motions in vehicles generate more carbon dioxide than continuously moving vehicles. This effect is greater multiplied by the load of the vehicles, steepness of road and density of traffic. The presence and proximity of vegetation covers is potentially able to offset the carbon dioxide contributions from vehicles and maintain a lower ambient concentration level.
