Hebei tightens emission standards to tackle pollution

Hebei province has released revised emission standards for high-polluting industries in a move to improve air quality.

The stricter standards, which came into force on March 1, cover the province's key industries, including steel, cement and flat glass, and also apply to coal-burning boilers.

The requirements are even tougher than the national standards, and some have been drawn up in line with international standards.
