Scientists were expecting the hole in the ozone layer to be closed by now after all countries banned the use of carbon tetrachloride. They were mystified by continuing emissions and ozone depletion. Finally, scientists from several areas got together to pinpoint the source of the carbon tetrachloride. You guys want to make a guess? Yep. China.

"Not only that, but despite the phase out of carbon tetrachloride production for emissive use in 2010, we found no evidence for a subsequent decrease in emissions."
In fact, emissions from certain regions may have increased slightly since 2010. The results from the study show the emergence of a new source of emissions from the Shandong province of China after 2012.
