Beijing's public transport to go greener

Green vehicles make for blue skies.

At least that's the philosophy behind a decision by Beijing transport authorities to replace more than 2,500 aging air-choking buses with new-generation clean people movers before next year's Olympic Games.

Feng Xingfu, deputy general manager of Beijing Public Transport Holdings Ltd, said 2,810 environmentally friendly vehicles would be purchased, and at least 80 percent of the buses would come fitted with diesel engines that meet the European IV standard for emissions.
