The Montreal Protocol has been signed by 197 countries around the world, including Canada, the U.S., and China.
That is until last year, when scientists from the National Oceanic and Atmospheric Association found that global emissions of Trichlorofluoromethane (CFC-11) have actually been increasing since 2013.
After analyzing weather and wind patterns to determine the origin of the gas increase, it led them to eastern mainland China, around the Shandong province.
Manufacturers told the EIA they continued to use the banned product because of its better quality and cheaper price.
However, Rigby said scientists and watchdogs didn’t know just how much manufacturers in China were emitting — about 7,000 tonnes of CFC-11 since 2013 in that area alone.
Rigby also mentions that CFC-11 is a greenhouse gas, about “5,000 times more potent than carbon dioxide at warming the climate.”.
But Rigby said if the increased emissions from eastern China aren’t stopped soon, the healing process could be delayed by “potentially decades. »
