The Chinese province of Henan will increase water and electricity tariffs for cement and steel producers that have failed to meet ultra-low emissions standards, said the provincial environmental regulator.

Henan is home to six of the country’s 20 most-polluted cities, reports Reuters. To address the emissions, companies that do not meet emissions treatment or clean transportation requirements will have to pay an additional CNY0.05-0.1/m3 (US¢0.7-1.4/m3) for water and an extra CNY0.01-0.06/kWh for electricity, said Henan Province’s Department of Ecology and Environment.

Following upgrading their emissions control equipment to comply with the ultra-low emissions standards, cement companies can apply to have the surcharge stopped.
