(ECNS) -- Beijing's environmental protection bureau will join hands with other municipal departments to develop a "congestion charge" system in 2014, in an effort to ease traffic jams and cut air pollution, the Beijing News reported on Thursday.
The charge system will be developed by the end of 2014, and will be implemented by 2015 at the earliest.
The information was included in a document called "Detailed rules on controlling mobile source pollution" released by the Beijing Municipal Environmental Protection Bureau.
According to the document, a total of 200,000 old vehicles will be phased out of the city, and the capital will upgrade more than 700 electric buses and 1,950 fueled by natural gas by 2014.
