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.

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. MeBr Critical Use Exemption Ozone Depletion Potential 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. 70% 2005 2006 2007 2008 2009 2010 2011 Requested by Applicants Nominated by U.S. Authorized by Parties Allocation - Stocks Allocation - New Production 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. ------- |
