Clean air campaign targets buses, trucks

About 1,900 public buses are to be refitted and thousands of trucks will be rerouted around Beijing this summer, in order to keep skies there blue and the air clean, the Ministry of Transport has said.

From next month, all commercial passenger buses entering Beijing will be required to meet national emissions standards, it said.

After a two-month investigation that began in March, the ministry found that 2,610 long-distance buses entering the city failed emissions tests.
