The goal is to close all coal-fired boilers in the city by 2020, according to the official Xinhua news agency.
The closures of polluting enterprises will be held in four districts (one city and three in the periphery).
Beijing region has gradually eliminating major sources of pollution (such as coal power plants) yet have proliferated small sources of pollution.
The announcement came almost at the same time a new warning from the National Center for Environmental Control by heavy pollution to the Beijing-Tianjin-Hebei region over the next Tuesday and Wednesday.
