Abstract
With the continuous development of urban public transportation, the harmful GHG emissions and pollutants generated by itself and the consequent issues such as the losses of residents’ health, economic value and residents’ welfare have become the focus of social attention. In order to study the impacts of promoting new energy vehicles on public transportation pollution mitigation and residents’ health benefits, this paper adopts the LEAP model to build some scenarios that fulfill different development needs to quantitatively analyze the ownership of new energy buses, the reduction of pollutants and the losses of residents’ health welfare. It is concluded that promoting new energy buses comprehensively can significantly reduce the emissions of atmospheric pollutants and the economic losses of residents’ health, but cannot fully realize the targets of greenhouse gas reduction under Life Cycle Analysis.
Highlights
The pollutant emissions of the buses can be calculated by the following formula: Emissioni, j,k,t = ECt × EmiRati, j,k + ECt × μ j × Emifac j,k where k is the type of pollutant emissions, which includes greenhouse gas carbon dioxide CO2 and pollutants such as carbon monoxide CO, nitrogen oxides NOx and particulate matter PM10; EmiRati, j,k is the emission factor of pollutantkkby the bus type i using fuel type j; μ j is the energy consumption caused by unit fuel type j; Emifac j,k is the emission factor of pollutant k discharged by fuel type j
At the early stage, the vehicle growth rate is less than the elimination rate, which indicates that this period is the transition period of update from the traditional energy buses to the energy-saving buses or the new energy buses
3) Comparing the setting scenario business as usual (BAU) and INEV, CCS and INEVccs, IBS 20% and INEV20%, IBS 30% and INEV30% respectively, the results show that promoting new energy buses vigorously can make the economic losses of residents’ health reduced significantly
Summary
Facing the severe challenges of the global resource crisis and environmental pollution, all the countries are actively seeking countermeasures to achieve the dual mandate of environmental protection and social economic development. In order to study the impacts of promoting new energy vehicles on public transportation pollution mitigation and residents’ health benefits, this paper adopt the LEAP model (Long Range Energy Alternatives Planning System) to build some scenarios that fulfil different development needs to quantitatively analyze the ownership of new energy buses, the reduction of pollutants and the losses of residents’ health welfare. It is an urgent and critically important to comprehensively describe the opportunities and impacts of actively seeking energy security and achieving emission mitigation of pollutants
