The increase in US transit ridership in 2008 has been attributed to the increase in fuel price. This study investigates the extent to which the increase in fuel price influenced the use of transit and whether this in turn influenced the reduction in CO2 emissions. The results indicate that the number of transit trips in an urban area increases significantly with increase in fuel price. Change in fuel cost also has a negative association with emissions although changes in transit trips do not have significant association with CO2 emissions.
