Lowering PM 2.5 written into Beijing pollution reduction law

A reduction of PM2.5 particles in Beijing's air was written into law on Wednesday and given priority status for the city's government.

The city's legislature passed the high-profile Air Pollution Prevention Regulation at the end of its people's congress plenary session.

The regulation provides a general framework for action that will be augmented by detailed directives to be published soon. It will take effect on March 1.
