Scientists Detect Possible Illegal Emissions of CFC-11

Mysterious rise in emissions of ozone-damaging chemical

Scientists have detected an unexpected rise in atmospheric levels of CFC-11, a chlorofluorocarbon (CFC) highly damaging to the ozone layer. Banned by the Montreal Protocol in 1987, CFC-11 was seen to be declining as expected but that fall has slowed down by 50% since 2012.

Researchers say their evidence shows it's likely that new, illegal emissions of CFC-11 are coming from East Asia. These could hamper the recovery of the ozone hole and worsen climate change.

Someone, Somewhere, is Making a Banned Chemical that Destroys the Ozone Layer

Emissions of a banned, ozone-depleting chemical are on the rise, a group of scientists reported Wednesday, suggesting someone may be secretly manufacturing the pollutant in violation of an international accord.

Emissions of CFC-11 have climbed 25 percent since 2012, despite the chemical being part of a group of ozone pollutants that were phased out under the 1987 Montreal Protocol.

    play stupid games win stupid prizes

    Unless their manufacturing technique involves mocking the PRC I think they're safe. The worst such a company would get is a cease-and-desist letter they couldn't bribe their way out of due to international political pressure.
