Premier Li Qiang has signed an amendment to the country's regulation on ozone-depleting substances, as the country strives to implement the Montreal Protocol on Substances that Deplete the Ozone Layer, according to a media release from the State Council, the country's cabinet.

The amendment rules that enterprises that generate ODS as by-products should not discharge the substances directly. Instead, they should dispose of them in an environmentally friendly manner.

Companies that receive administrative penalties for violating the regulation will have their misconducts included into their credit records, and the violations will be made public
