OVER THE PAST SEVERAL DECADES, EPA’S STRATOSPHERIC PROTECTION
DIVISION AND ITS PARTNERS HAVE MADE SIGNIFICANT STRIDES TO
PROTECT THE EARTH’S STRATOSPHERIC OZONE LAYER, THE ENVIRON-
MENT, AND PEOPLE’S HEALTH.
The ozone layer acts like a shield in the
upper atmosphere (the stratosphere), to
protect life on Earth from harmful ultra-
violet (UV) radiation. In 1974, scientists
discovered that emissions of chlorofluo-
rocarbons, or CFCs, were depleting
ozone in the stratosphere. CFCs were a
common aerosol propellant in spray
cans and were also used as refrigerants,
solvents, and foam-blowing agents.
In the 1980s, scientists observed a thinning
of the ozone layer over Antarctica, and peo-
ple began thinking of it as an “ozone hole.”
Additional research has shown that ozone
depletion occurs over every continent.
As our scientific knowledge about ozone depletion
grew, so too did the response to the issue. In 1987,
leaders from many countries came together to sign a
landmark environmental treaty, the Montreal Protocol on
Substances That Deplete the Ozone Layer. Today, more than
190 countries—including the United States—have ratified the treaty. These
countries are committed to taking action to reduce the production and use of CFCs and
other ozone-depleting substances to protect the ozone layer. Countries are phasing out
the production and consumption of ozone-depleting substances in groups, focusing on
those chemicals with the most ozone-depleting potential first, followed by those that pose
the next greatest ozone-depletion risk (in this document, these chemicals are referred to as
“first-generation” and “second-generation” substances, respectively).
