We Know Where The Excess Chemicals That Destroy The Ozone Layer Come From

Exactly one year ago, a team of scientists detected an increase in chemicals that destroy ozone, known as chlorofluorocarbons (CFCs).

Because they had been banned in 1987 by the Montreal Protocol, there was only one explanation: somewhere someone should be using CFC in sufficient quantity to delay the recovery of the ozone hole a decade or more.

Now, after much speculation, the whereabouts and the magnitude of these harmful emissions have been confirmed in a new study, also published in Nature. And the origin is in the northeast coast of China.

According to the results, CFC emissions in this industrialized region have practically not stopped, nor have they diminished. In fact, between 2008 and 2012 and between 2014-2017, emissions of CFC-11 (the second most abundant chlorofluorocarbon in the atmosphere) increased by approximately 110%.

“To produce an increase of this caliber,” the authors point out in the study, “it would be necessary to destroy refrigerators at a rate 10 times greater than that estimated for all of China for 3 years or a demolition of more old buildings than previously predicted to everyone over a period of 20 years (2020-2040).”
