Ozone layer: Banned CFCs traced to China say scientists
CFC-11 is also known as trichlorofluoromethane, and is one of a number of chloroflurocarbon chemicals that were initially developed as refrigerants during the 1930s.
That team reasoned that they were seeing new production of the gas, coming from East Asia. The authors of that paper argued that if the sources of new production weren't shut down, it could delay the healing of the ozone layer by a decade.Further detective work in China by the Environmental Investigation Agency in 2018 seemed to indicate that the country was indeed the source.
"This new study is based on spikes in the data on air that comes from China," lead author Dr Matt Rigby, a reader at the University of Bristol, told BBC"Using computer simulations of the transport of these gases through the atmosphere we can start to put numbers on emissions from different regions and that's where we come up with this number of around 7,000 tonnes of extra CFC-11 emissions coming out of China compared to before 2012.
