THE BIG PICTURE:
Working together to
protect the ozone layer
Worldwide participation has made
the Montreal Protocol a success.
The Montreal Protocol—and its
Amendments and Adjustments—are
reducing stratospheric concentrations
of chlorine and bromine and associated
skin cancer incidence and mortality.
But... there is still work to be done
to reduce remaining uses of ozone-
depleting substances, including
methyl bromide, and restore the
ozone layer.

PHASING OUT METHYL
BROMIDE WORLDWIDE;
Reducing critical uses
Global authorizations for critical use
methyl bromide decrease each year,
while the United States' proportion
increases. Although the United States
has eliminated more methyl bromide
use than any other country with critical
use needs, it continues to use the
majority of methyl bromide worldwide.

CONTINUING PROGRESS
IN THE UNITED STATES:
Phasing out
methyl bromide
U.S. requests, nominations, and
authorizations steadily decrease
each year.
The transition to methyl bromide
alternatives continues to be an
important priority, as the
last high-ODP gas to be phased out
in the United States.

Thank you for your continued efforts to phase out methyl bromide and protect our
Earth's ozone layer. EPA applauds the hard work of agricultural users, industry, researchers, and others to foster the
transition to methyl bromide alternatives and explore innovative approaches to reducing use and emissions. These efforts are
a critical part of successfully implementing the Montreal Protocol.
