THE last six factories in China producing CFC, an ozone depleting substance, have agreed to stop production.

The six factories signed a deal with the State Environmental Protection Administration on Saturday in Changshu, Jiangsu Province. China has now honored its promise to phase out CFC 2 1/2 years ahead of the schedule set in the Montreal protocol on banning ozone depleting substances, said a SEPA official. Total production capacity of 122,000 tons will be phased out according to the deal signed by SEPA, China National Chemical Construction Company and the six factories.
