OZONE DEPLETION: POLICY
Environmental Impacts of Future Halocarbon Emissions," K.J. Holmes (Dept.
Geog., Johns Hopkins Univ., Baltimore MD 21218), J.H. Ellis,
Environ. Sci. & Technol., 30(8), 348A ff., Aug. 1996.
Reports an analysis which integrates all major components of the problem:
demographic, economic, and regulatory processes; technological factors that
translate production into emissions; and environmental processes that determine
impacts. If even a small percentage of nations continues to expand halocarbon
production at modest rates, the ozone hole will not be eliminated. Continued use
of small amounts of ozone-depleting substances for essential uses and the
failure to adequately replace all of them can eliminate the possibility of
returning the atmosphere to pre-ozone hole conditions.
