A total of 1,315 companies have been punished after a three-month overhaul was launched in northern China's Shanxi Province, one of the regions suffering the worst smog in China this winter.
The campaign by local environmental law enforcers started mid-December, and focused on construction and production that violated regulations, according to the provincial environmental protection department.
Fines worth 21.5 million yuan (3.1 million U.S. dollars) have been meted out and 33 people punished. More than 200 small heavy-polluting companies have been closed and 95 others ordered to limit or suspend production.
The department sent five work teams to supervise the campaign in 67 counties.
