- philipkglass 8y agoThere was a report earlier this year that China is still producing industrial quantities of banned CFC-11, mostly for use in foam blowing. https://eia-global.org/reports/20180709-blowing-it-illegal-production-and-use-of-banned-cfc-11-in-chinas-foam-blowing-industry https://eia-global.org/reports/20180709-blowing-it-illegal-p... Apparently carbon tetrachloride is used as a chemical precursor to CFC-11: https://en.wikipedia.org/wiki/Carbon_tetrachloride#Historic_uses https://en.wikipedia.org/wiki/Carbon_tetrachloride#Historic_... But I would expect that there would be limited releases of CCl4 itself if the main use were in manufacturing other chemicals. Maybe they're just manufacturing the whole gamut of chemicals banned by the Montreal Protocol and using them in exactly the same ways they were used historically.
