During the progress of the economic development in Beijing, the analysis on the development of traffic and transport, and the role in the energy saving becomes increasingly important. In this research on low-carbon transport in Beijing, first focus is on analysing the current status of transportation development and carbon emissions in Beijing. Then, field measurement method is used to calculate Beijing carbon emissions, EKC curve is fitted to analyse development modes of traffic carbon emissions and predict the response of carbon reduction schemes by ARIMA model. Finally, empirical analysis indicates the varying regulation traffic development. From there, the paper points out existing problems and put forward policy suggestions.
