'Impossible' that large amounts of ozone-harming CFC-11 used

No large-scale use of CFC-11, an ozone-depleting substance, was identified in China in a campaign looking into the polyurethane foam sector.

Analysis of consumption of legal foaming agents and output in the sector also shows that significant consumption of the substance in the country is "impossible", according to a statement from the International Environmental Cooperation Center, Ministry of Ecology and Environment.

The center made the comments late on Thursday, replying to China Daily's interview request, after the journal Nature published a study claiming that China is to blame for much of the increase in the banned ozone-depleting substance, CFC-11, since 2013.
