With the emergence of the response to climate change as a global agenda, UNFCCC member countries must report their Greenhouse Gas (GHG) emissions and absorptions. With conventional carbon emission estimation methods such as the IPCC Guideline, however, it is impossible to measure reduction of carbon emissions by U-City services. Therefore, this study proposed estimating carbon emission reductions by using U-transportation services as a model because this service appears to be the most effective among U-City services in terms of carbon emission reduction. This approach which is unique in Korea has also attempted to quantify the reduction of carbon emissions by a U-transportation service by applying it to Dongtan U-City. The average vehicle speed before U-transportation service was set to 29.62 km/hr based on reference data. The average vehicle speed after application of U-transportation service was estimated based on 22.6% of the average velocity growth rate which was obtained by applying ITS (Intelligent Transport System) to three cities (Daejeon, Jeonju, and Jeju). Because of increase in vehicle speed by U-transportation service, the carbon emissions in Dongtan U-transportation decreased by 10.7% from 591,678 tCO2e/y to 528,527 tCO2e/y. In terms of velocity growth rate by U-transportation service, the regression between carbon emissions (0% to 40% section) and velocity growth by U-transportation service was estimated.
