Emissions of banned ozone-eating chemical somehow are rising

WASHINGTON — Something strange is happening with a now-banned chemical that eats away at Earth’s protective ozone layer: Scientists say there’s more of it — not less — going into the atmosphere and they don’t know where it is coming from.

When a hole in the ozone formed over Antarctica, countries around the world in 1987 agreed to phase out several types of ozone-depleting chemicals called chlorofluorocarbons (CFCs). Production was banned, emissions fell and the hole slowly shrank.

But starting in 2013, emissions of the second most common kind started rising, according to a study in Wednesday’s journal Nature . The chemical, called CFC11, was used for making foam, degreasing stains and for refrigeration.
