Scientific Assessment Presents Status, Expectations for Ozone Layer
"A new NOAA-led assessment of the global ozone layer says the U.S. has reduced by 97-98 percent the production of ozone damaging substances since the late 1980s. The assessment is one in a series of synthesis and assessment reports coordinated by the U.S. Climate Change Science Program.

The report also offers a glimpse into expectations for recovery of the ozone layer in a changing climate, as well as the first detailed look at U.S. role in emitting — and reducing the emissions of — the chemicals that deplete the ozone layer.
