On March 14, 2007, the United States Submitted A Proposal To Adjust The Montreal Protocol To Accelerate The Phase-Out Of Ozone-Damaging Chemicals. The U.S. proposal includes four elements that can be considered individually or as a package:
These proposals further U.S. efforts to address ozone layer protection by calling on the global community to act more quickly in phasing out HCFCs. They also could produce climate benefits.
The U.S. Continues Its Strong Leadership In Ozone Layer Protection. Since the Montreal Protocol was signed in 1987, the U.S. has achieved a 90 percent reduction in the production and consumption of ozone-depleting substances - ending the production and import of over 1.7 billion pounds per year of these chemicals. Faster healing of the ozone layer will help prevent human health damages caused by excess UV radiation, including skin cancer.
U.S. Actions Under The Current Montreal Protocol And Clean Air Act Requirements Have Also Helped Protect Against Climate Change. Ozone-depleting substances - particularly CFCs - are damaging to the Earth's climate system. In 2005, the U.S. reduced annual emissions of ozone-depleting substances by 1,500 million CO2-equivalent metric tons per year. U.S. actions achieved a cumulative emissions reduction of about 13,000 million CO2-equivalent metric tons from 1987-2005 (not accounting for some offset from the influence of ozone depletion on the climate).
Worldwide, The Montreal Protocol Has Cut In Half The Amount Of Global Warming Caused By Ozone-Destroying Chemicals That Would Have Occurred By 2010 Had These Chemicals Not Been Controlled.
