Abstract: In recent years, the Tibet autonomous region has stepped up its efforts in green, low-carbon and circular development. The purpose of this paper is to study the path of low-carbon transport in Lhasa on the basis of systematic study of the current general urban low-carbon transport policy system, using empirical research method and kaya model, reasonable calculation of traffic carbon emissions data in Lhasa. The results show that the total carbon emission of transportation industry in Lhasa is increasing year by year with the economic growth, which shows that traffic carbon emission is closely related to the economy, and freight transportation accounts for the largest proportion of traffic carbon emission, which is increasing year by year. On this basis, combining with the geographical advantages and environmental advantages of Lhasa, this paper scientifically designs the path and framework of low-carbon transportation in Lhasa, aiming at alleviating the greenhouse effect to a certain extent and accelerating the change of citizens' travel mode.
