Vehicles with yellow labels whose emissions do not meet National I standards will be forbidden from Shenzhen roads from July 1.
The city government has reserved the right to restrict high-emission vehicles from entering the roads if the air quality is substandard during the Universiade.
By the end of July, greener fuel of National IV standard will be promoted citywide and the environment commission will tighten inspection over high-emission vehicles, buses and heavy-duty trucks, the commission said Friday.
In a move to improve the city's environment and reduce pollution, the environmental protection authority will speed up the construction of 11 wastewater treatment facilities in Longgang and Bao'an districts. This is expected to reduce water pollution along with chemical emissions, and acid rain will be rarer.
Shenzhen is using the Universiade as an opportunity to tackle its escalating environmental problems, Liu Zhongpu, head of the city environment commission, said.
"Our goal is for air quality in Shenzhen to be at the same standard as Beijing's at the time of the 2008 Olympics," Lin Hanzhang, deputy chief of the commission, said.
"To achieve a greener Universiade, we will initiate contingency plans including restricting some vehicles on even-numbered days, and others on odd-numbered days, if the air quality deteriorates or weather conditions are exceptionally bad," Lin said.
The city will put to use 3,800 vehicles including 2011 electricity-powered buses devoted to Universiade transport. The vehicle providers are auto manufacturers including BYD and Wuzhoulong Motors.
