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.
