China
will start to implement the national phase III and phase IV auto vehicle emission
standards in 2007 and 2010, respectively, as learned from the National Environmental
Science and Technology Conference recently held in Beijing.
For each
single engine, its pollutant emission could be reduced by more than 30 % when
standards of a higher phase are introduced.
According to an official
of the Department of Science, Technology and Standards of the State Environment
Protection Administration, implementation of these two sets of standards could
cut the emission of road vehicles by 1.8 million tons in nitric oxide, 2.2 million
tons in hydrocarbon and 16 million tons in carbon monoxide between 2008 and 2012.
This is expected to bring tremendous environmental benefits to society, promote
technological updates and catch up with international level as well as facilitate
the export of related products.
The official said that by 2010, China
will reduce her gap with internationally advanced levels from eight years in 2000
to five years regarding emission control technologies.
According to the
latest statistics, China has become the third largest automobile producer in the
world, with an annual output exceeding 5 million units and possessing nearly 33
million units.
China's prevention and control of automobile pollution
started in the 1980's with the issuance and implementation of emission standards
of automobiles. In 1999, the Administration mapped out the standard s on the control
of harmful materials of vehicle-use gas and the phase I and phase II pollutant
control standards of light vehicles and compression ignition engine (CIE) equipped
on heavy vehicles, which are the equivalent of Europe I and II standards.
