Mysterious rise in emissions of ozone-damaging chemical - BBC News
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.
========================================
East Asian countries like China & Vietnam are well known for cutting corners when they produce products, especially those for export. Using either old stocks or new production CFC-11 as propellants in spray cans is not hard to imagine.
