To be able to understand CFCs further, let’s start by learning what it really is. CFC stands for chlorofluorocarbon “This new paper scientifically confirms that large scale CFC-11 emissions came from eastern China, as identified by our investigations and reports,” said Avipsa Mahapatra, climate campaign lead, EIA-U.S. EIA has calculated that illegal CFC-11 use in China may have created a total bank of almost 4 gigametric tons of CO 2 equivalent between 2013 and 2017 contained in existing polyurethane foam products, much of which is yet to be emitted into the atmosphere.
