MORE
than 7,153 models for sale on the Chinese market
can meet the stringent Euro 3 emission standards,
and 1,358 models have been equipped with an
on-board diagnostics system, a device to issue
warnings if exhaust wastes are found to be over
the limit.
China I
China started to implement the first generation
of emission standards in 2000, equivalent to
the Euro 1 standard in the European Union.
China II
China applied the second generation of motor
emission standards nationwide in July 2004.
The standard, equivalent to Euro 2, reduces
carbon monoxide emissions by 30 percent and
hydrocarbons by 55.8 percent.
Major cities acted much earlier, with Beijing
enforcing Euro 2 standards in 2002, and Shanghai
in March 2003 as a trial operation.
China III
China introduced new motor vehicle emission
standards in July, 2007, which further lower
exhaust wastes by nearly 30 percent on average.
The new standards, equivalent to Euro 3 standards
in the European Union, limit sulfur levels to
a maximum 150 ppm.
It also required higher standards on purifying
equipment, low-temperature emission controls
and engines. Car makers are also asked to install
an on-board diagnostics system to monitor gas
emissions. The new standard was approved by
the State Environmental Protection Administration
(SEPA) in April, 2005.
China IV
China planned to introduce the China 4 emission
standards by 2010 across the country. Beijing
is expected to enforce the stricter standard
in 2 008 as its commitment to create a greener
environment for the 2008 Beijing Olympic Games.
From 2008, new vehicles on sale in the Beijing
market must meet the China 4 emission standards.
Meanwhile, the nation also plans to introduce
a revised lead-free gas standard at the end
of 2009, which will drive gas with sulfur levels
of 500 ppm out of the market.
