LEAP Based Analysis of Transport Energy Consumption and Air Pollutants Emission in Xiamen City

Due to a large proportion of energy consumption and pollutant emissions in transport sector,the study of measure of energy saving and emissions reduction in the transport sector is particularly urgent.A transport model of Xiamen-2008Tra based on Long Range Energy Alternatives Planning System(LEAP) was developed,taking Xiamen transport sector as a case study.The energy consumption and emissions of CO2,SO2,NOx and PM10 for the base year 2008 and extrapolated till 2030 were analyzed.The model established Business as Usual(BAU) scenario and Best Case(BC) scenario totally.BAU scenario was pertaining to a base line reference scenario,in which the government was assumed to do nothing to inhabit the increase of road transport energy demand.BC scenario was considered the most optimized case,which included five available reduction subscenarios such as private vehicle control,fuel economy regulation,promoting new alternative power vehicles,fuel tax and biofuel proportion.Results showed that comparing with BAU scenario,the BC scenario saved 36.08% of energy consumption,and emissions of CO2,SO2,NOx and PM10 decreased by 40.46%,47.06%,32.07% and 44.91% respectively.Private vehicle control had a better effect on reducing energy consumption and pollutants emission than other sub-scenarios.
