Fluorocarbons
in the Environment

In the 1970's concern about
possible effects of chlorine form CFCs on stratospheric ozone
triggered a major research effort in atmospheric science.
Fluorocarbon producers worldwide played a significant role in
identifying research objectives and providing support through the
Chemical Manufacturers Association's Fluorocarbon Program Panel. This
effort has led to a better understanding not only of the complex
processes controlling ozone in the stratosphere, but also of the
factors affecting ultraviolet radiation at ground level and of global
temperature trends. Even though uncertainties remain, there is now
consensus that emissions of fully halogenated CFCs, notably the
Montreal Protocol, have been developed and continue to be updated,
utilizing in part scientific data developed by the Fluorocarbon
Program Panel.
As part of the industry-wide effort to
find ways of reducing CFC emissions of fully halogenated CFCs,
fluorocarbon producers are developing a number of hydrogen-containing
fluorocarbons as potential alternatives. Their possible environmental
effects, too, are being carefully investigated, using much of the new
knowledge in atmospheric science acquired during recent years. Aware
of their responsibility, producers are making a concerted effort to
ensure the safety of the new products.
