Five New Pollutant Emission Standards Released
The Ministry of Environmental Protection (MEP) of China released five national pollutant emission standards on 30 August, including national standards (phase IV) for motorcycles and electric motorcycles, as well as pollutant emission control requirements for hybrid electric vehicles.
Figures from the MEP show that the output of China’s motorcycle industry is growing rapidly. There were as many as 95.14 million motorcycles in use across the country as at the end of 2015. It is estimated that in 2015, the share of major pollutants emitted by motorcycles in the national total from all types of motor vehicles was 12.7% for carbon monoxide (CO), 13.5% for hydrocarbons (HC) and 1.6% for nitrogen oxides (NOx).
According to Zou Shoumin, director general of MEP’s Department of Science, Technology and Standards, the ministry has issued national emission standards (phase IV) for motorcycles and mopeds in a bid to effectively control pollution arising from the proliferation of motorcycles, and to promote technological advances and structural improvements in relevant industries. Compared with current standards, the new ones feature amendments mainly in five areas: expand the applicable scopes of the standards to include new emission control requirements for three-wheeled diesel motorcycles; put new pollutants under regulation and add new control requirements for particulates emitted by three-wheeled diesel motorcycles; further tighten the upper limits for emissions; impose higher requirements on the durability of emission controls; and introduce more comprehensive environmental management and technical requirements.
The MEP stipulates that all newly sold and registered motorcycles and mopeds should fulfill the requirements of the new emissions standards from 1 July 2019. Zou said he expects that after the implementation of national phase IV standards, say for a period of three years, the total volume of pollutants emitted by all newly produced motorcycles during their service lifetime would be reduced when compared to the levels when national phase III standards were in force. The magnitudes of reduction are estimated as follows: CO, 6.5 million tons; HC, 2 million tons; and NOx, 300,000 tons.
