Reuters are reporting that China's smog-ridden Hebei province has asked steel, cement plants and utilities to adjust their production schedule between November and January as part of its battle against pollution.
Companies ranging from petrochemical companies to metal producers will reduce output or shut down on heavy pollution days.
The province has already pledged to impose what it called "special emission restrictions” on local mills by setting up tough standards for sulphur dioxide and other pollutants.
Hebei is expecting weather conditions that will help trap pollutants and worsen its problems in winter.
