Potent greenhouse gases and ozone depleting chemicals called CFCs are back on the rise following an international ban

Emissions of a small group of chlorofluorocarbons (CFCs), man-made chemicals that destroy Earth’s protective ozone layer and fuel global warming, are back on the rise after their production was all but banned more than a decade ago, a new study concludes. Emissions of the vast majority of CFCs have steadily declined since countries phased out […]

Mystery emissions of ozone-damaging gases are fuelling climate change

It's not just carbon dioxide that causes climate change. Chlorofluorocarbons, or CFCs, are a group of chemicals that were widely banned because of their effects on the ozone layer. Unknown sources are emitting more of these compounds, which are also powerful greenhouse gases.

Restoration of the ozone layer is back on track, scientists say

Rogue emissions from China of ozone-depleting chemicals had threatened to delay recovery by a decade. But the emissions were stopped, according to a U.N.-backed report.
