Hebei Province, known for the worst air condition in China, vowed on Wednesday to clear the smog by reducing coal-related pollution.
Hebei Vice Governor Zhang Jiehui said the province would cut emissions from coal-fired power stations by half.
Stations that can not meet the goal will be shut down, according to the provincial government.
The government also plans to close all solid clay brick kilns as they cause heavy pollution.
Coal emissions contribute half of the air pollution in Hebei, the vice governor said at an air pollution control meeting.
