A Guide to Information on Greenhouse Gases and Ozone Depletion

Item #d94feb139

HFCs cleared: A comprehensive study by U.S. researchers shows that hydrofluorocarbon substitutes for CFCs do not destroy stratospheric ozone. (See Ravishankara paper in Prof. Pubs./Gen. Interest, and news articles in Chem. Eng. News (pp. 5-6, Jan. 10), Intl. Environ. Rptr. (p. 9, Jan. 12), Chem. & Industry (p. 45, Jan. 17), and New Scientist (p. 15, Feb. 5). Independent of this development, Bosch, a leading manufacturer of refrigerators, decided to abandon HFCs for chemicals like pentane and isobutane (ibid., p. 4).

Final HCFC exemptions were published by the U.S. Environmental Protection Agency from the ban on non-essential goods made with hydrochlorofluorocarbons. They include portable fire extinguishers and aircraft cleaning fluids. See Intl. Environ. Rptr., pp. 16-17, Jan. 12, or Federal Register, Dec. 30, p. 69638.

Item #d94feb140

"With Europe's CFC Phaseout 11 Months Away, Refrigeration Industry Starts to Panic," Global Environ. Change Rep., pp. 1-3, Feb. 11. A feature report on how Europe's refrigeration industry must reduce its extensive use of CFCs to zero in the next 11 months. (This topic is also discussed in Intl. Environ. Rptr., pp. 167-168, Feb. 23.)

Item #d94feb141

"NATO to Help Reduce Military Use of Ozone-Depleting Compounds," ibid., pp. 4-5. A NATO meeting on the role of the military in ozone protection (Brussels, Jan. 1994) concluded that much progress has been made, but significant challenges remain for some critical applications.

Item #d94feb142

"CFC Phase-Out Moves Quickly," A. Newman, Environ. Sci. & Technol., pp. 35A-37A, Jan. Speakers at the 1993 International CFC and Halon Alternatives Conference (Washington, D.C., Oct. 1993) discussed how the phase-out in general is proceeding faster and at less cost than expected.
