Banned Substance Still Depleting Ozone Layer: NASA

Washington: In a significant revelation, NASA researchers have shown that the earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source, decades after the compound was banned worldwide.

Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone.

Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-12.

However, new research suggests worldwide emissions of CCl4 average 39 kilotons per year, approximately 30 percent of peak emissions prior to the international treaty going into effect.

"We are not supposed to be seeing this at all. It is now apparent there are either unidentified industrial leakages, large emissions from contaminated sites or unknown CCl4 sources," said Qing Liang, an atmospheric scientist at NASA's Goddard Space Flight Centre in Greenbelt, Maryland.

1. Chemtrails?

2. As with any other international agreement, somebody (or several) is cheating.

Probably US-born multinationals in 3rd world countries. After all, they have to make a (untaxed) buck somehow.

3. Big world + few sets of appropriately tuned "eyes" = little adherence to regulations

Probably the usual suspects - China (highly likely), Russia/stans, USA, India - but don't forget
the total lack of control (or safety or anything) of the third-world "recycling" slums that are the
recipients of so much of the waste from around the world ... each little bit of "lost" gas ends up
in the atmosphere just as much as the CO2 from exported coal ...
