Study on the control targets and measures for total diesel consumption from mobile sources in Beijing, China

Based on the current air pollution control and CO 2 emission reduction policies, this study analyzed energy structure, number of motor vehicles nonroad mobile machinery, consumption pollutant emissions in Beijing. Furthermore, diesel characteristics challenges for key fields were investigated, such as medium- heavy-duty trucks, long-distance passenger tourist vehicles, which are areas with difficult-to-reduce consumption. Control targets measures total also proposed. The results indicated that higher per unit area Beijing is related to larger car freight truck populations. In recent decades, has increased, vehicle type structure been optimized, proportion high standards absolute have decreased. Among these, nitrogen oxides (NO x ), fine particulate matter (PM 2.5 ) volatile organic compound (VOC) different models decreased by 39.5%, 75.3% 42.8%, respectively, while carbon dioxide (CO from combustion 32%. Moreover, medium large trucks construction machinery main contributors These types difficult reduce, their replacement new-energy relatively limited. follows. First, a green transportation mode can be adopted goods converted roads railways. Second, fuel realized tightening limits, setting appropriate maximum retirement life, establishing low- or ultralow-emission zones, demonstration plots electric (EV) substitution machinery. To improve quality take lead neutrality future, must further accelerate adjustment development sector. Carbon neutralization an important opportunity reduction, synergistic atmospheric strengthened.
