Guangzhou will implement a new vehicle exhaust emission standard
this year to improve the environment, local media reported
The Guangzhou Municipal Government has handed in a detailed plan
to the State Council for approval to implement the State Phase III
exhaust emission standard this year, the city's environmental
protection bureau said.
Compared to the State Phase II standard implemented in Guangzhou
last July, the Phase III standard requires vehicles to reduce
exhaust emission by half, according to the bureau.
If approved by the State Council, the city government will ask
all the new vehicles in the market to install an on-board
diagnostics (OBD) system, which will check for problems in the
emission control system.
However, the bureau did not say what plans the government had
for old vehicles.
In Beijing, registration for vehicles that didn't meet the State
Phase III standard was stopped after Dec. 30, 2005.
A new vehicle would cost 1,000 (US$125) to 2,000 yuan more
because of the OBD system, said Liu Chao, a department chief of the
Guangzhou environmental protection bureau. Liu said the government
was discussing whether the extra cost could be subsidized.
Guangzhou's air pollution comes mainly from coal-powered plants
and vehicles with heavy exhaust emissions, the New Express
reported, citing Professor Hua Ben from South China University of
With the introduction of liquefied natural gas this year, air
pollution caused by burning coal will be gradually eradicated. The
city should focus more on vehicle emissions, Hua said.
Although the State Phase III standard brings good news for the
city's environment, the government should do more for old vehicles
that don't meet the standard, he said.
Even those vehicles meeting the new standard can increase their
exhaust emission if driven at a very low speed, Hua said. He
suggested the government should thus improve road traffic.
