Good news for the ozone layer: After a recent spike in CFC-11 pollution, emissions of this ozone-destroying chemical are on the decline. These findings suggest that the hole in Earth’s ozone ...

The chemical in question is CFC-11, a chlorofluorocarbon that was once commonly used for refrigeration, insulation, and other purposes. When emitted to the atmosphere, CFC-11 can loft into the ...

Their investigation traced trichlorofluoromethane (a chlorofluorocarbon, CFC-11) back to east Asia, and concluded that it was probably emitted by new, unreported production facilities.

Two international studies published in Nature show levels of CFC-11 emissions, one of the many chlorofluorocarbon (CFC) chemicals once widely used in refrigerators and insulating foams ...

Since 2013, annual emissions of a banned chlorofluorocarbon (CFC) have increased by around 7,000 tonnes from eastern China, according to new research. Since 2013, annual emissions of a banned ...

A few years ago, there were unexpected emissions of one of the banned chemicals -- chlorofluorocarbon-11, or CFC-11 -- in eastern China, though those numbers have also gone back down to expected ...

In 2018, factories in China were found to be the source of a spike in CFC-11 emissions. Previous research has identified East Asia as a source of CFC-113a and CFC-115 emissions, and more ...
