北京將執行更嚴格機動車排放標準降低PM2.5
[ 2012-02-27 10:35 ]

今年,北京將在全國率先執行更嚴格的機動車國五排放標準,力爭在2016年與國際接軌,實施相當于歐六排放標準的新車準入標準,有效控制機動車排放污染。

從北京PM2.5主要成因看,與能源消費直接相關的機動車排放和燃煤排放約占總量的40%(各占22.2%、16.7%)。未來較長一段時期,北京空氣質量將在連續13年好轉的基礎上,以降低PM2.5為重點,通過實施一系列的強制性措施,打一場提升空氣質量的攻堅戰。

 

Beijing will usher in a stricter vehicle emission regulation this year amid public discontent over air pollution, the city's economic planning agency said Friday.

Beijing will lead other provinces in the country in implementing the tighter National 5 vehicle emission standard, equivalent to the Euro 5 emission standard applied to passenger and light vehicles in EU member countries, the Beijing Municipal Commission of Development and Reform (BMCDR) said in a statement.

All cars sold in Beijing will be required to meet the new standard, according to the BMCDR. The commission did not give an exact timetable for the enforcement of the regulation, although cars that have already been sold will not be required to comply with the regulation.

The BMCDR said it hopes to boost the standard by 2016 to make it equivalent to the tighter Euro 6 emission standard.

The BMCDR said the move is aimed at "effectively controlling exhaust pollutants from automobiles," as the capital city has promised to reduce air pollution and make other environmental efforts.

Beijing's environmental protection authority began to use the PM2.5 air quality standard on Jan 12, as the city's persistent smog has raised health concerns among its residents.

The PM2.5 standard is more strict than the previous PM10 standard, as it allows for the monitoring of fine particles with diameters of 2.5 microns or less.

BMCDR said automobile emissions account for more than one-fifth of the city's PM2.5 particles.

The number of registered vehicles in the city exceeded 5 million this month, indicating that one in four Beijing residents owns a car. The municipal government implemented a license plate lottery system at the beginning of last year to limit vehicle purchases.
