A new study that was released after research by Massachusetts Institute of Technology, University of Bristol, and Kyungpook National University, points to China being responsible for a spike in illegal greenhouse gas. The emission of illegal greenhouse gas has damaged the ozone layer and is responsible “for a substantial fraction” of that increase in damage.
The study, according to an article on CNBC, says that China is responsible for 40% to 60% of the global increase in trichlorofluoromethane, or CFC-11, emissions between 2014 and 2017. This is in violation of the Montreal Protocol which was signed by 197 members, including China, that is there to address the production and consumption of any chemical that might damage the planet with regards harming the earth and its protective layer.
This chemical in question is connected to the production of foam insulation for refrigerators and buildings. These chemical infractions are not tied to the US trade talks but China has been forced to open up and discuss details about its local industries and of course this is one point that many international organizations would be interested in.
