The emission of an illegal greenhouse gas destroying the earth's ozone layer has increased – and according to a new study, China is responsible for "a significant portion" of this increase.
The study published on Wednesday showed that China accounted for between 40% and 60% of the global increase in trichlorofluoromethane or CFC-1
Scientists who conducted the study came from Bristol University in the United Kingdom, Kyungpook National University in South Korea, and the Massachusetts Institute of Technology in the US
The latest study also confirmed media and activist reports that China is behind them Increases could be stuck Emissions.
"Several considerations suggest that the increase in CFC-11 emissions from mainland eastern China is likely due to new production and use, in contradiction to the Montreal Protocol, the global production of chlorofluorocarbons to discontinue by 2010 ", the researchers wrote summary of the study.
The Montreal Protocol is an agreement signed by all 197 member states of the United Nations, including China, to regulate the production and consumption of chemicals that damage the Earth's protective coating. According to a report by the Canadian National Post
the treaty resulted in a "significant reduction" in harmful gases such as CFC-11, which then allowed the damaged ozone layer to be cured. Last year, The New published a report The York Times noted that Chinese factories had ignored the global ban on CFC-11 under the Montreal Protocol. They had continued to manufacture and use the chemical because it is a cheaper material for the production of foam insulation for refrigerators and buildings.
The Environmental Investigation Agency, a non-governmental activist group, reported similar results to the Times last year, based on its own research. The group said the Chinese authorities have begun to crack down on the illegal production and use of CFC-11.
