Abstract
In China, the growth of new energy vehicles is especially rapid and the explosive growth of the automobile brought an increasing impact on the environment. This paper selected Electric Vehicles, Hybrid Vehicles and Internal Combustion Engine Vehicles of the same model of BYD as the object. We established a Life Cycle Assessment with GaBi6 software and CML2001 model. The results show that in the whole life cycle, the influences of ADP, GWP and ODP of Electric Vehicles are less than that of Hybrid Vehicles and Internal Combustion Engine Vehicles. The impact of Electric Vehicles are 39%, 50%, and 4% of the Internal Combustion Engine Vehicles and the Hybrid Vehicles’ impact are 65%, 78% and 85% of the Internal Combustion Engine Vehicles. Electric Vehicles and Hybrid Vehicles have a clear improvement in these three types of impacts. The comparison results of AP, EP, FAETP, MAETP and POCP show that the potential impact of Electric Vehicles is greater than that of Hybrid Vehicles and Internal Combustion Engine Vehicles. At present, improving production technology and reducing the consumption of energy during production phase are effective measures to reduce the environmental impact of Internal Combustion Engine Vehicles and Hybrid Vehicles of China.
Highlights
Vehicle emissions are one of the main causes of urban traffic pollution in China
It is considered that the car body, chassis, wheel and interior decoration of Electric Vehicles and Hybrid Vehicles will be same with the Internal Combustion Engine Vehicles, the only difference is the power system
From the perspective of the life cycle of vehicles, Electric Vehicles has the potential to significantly improve the environmental impacts of Abiotic Depletion Potential (ADP), Global Warming Potential (GWP) and Ozone Depletion Potential (ODP), especially for carbon emission reduction
Summary
Vehicle emissions are one of the main causes of urban traffic pollution in China. 60% of CO emissions, 50% of NO emissions and 30% of HC emissions is caused by automobile .In China, the automobile industry has developed rapidly in recent years and the private cars ownership has reached 219 million in 2017[1]. The rapid growth of automobiles has brought a series of negative effects, such as heavy oil consumption, environmental pollution and traffic congestion. China has put forward to develop new energy vehicles and proposed many support policy such as subsidies and no travel restrictions [2]. In 2017, China produced 794 thousands and sold 777 thousands new energy vehicles, the production share reached 2.7% of all automobiles and ranked first in the world for three consecutive years. While new energy vehicles are being promoted in China, they encounter the controversy of whether the new energy vehicles are environment friendly
