 Lifetime
Commitments: Why Climate Policymakers Can't Afford to Overlook Fully Fluorinated
Compounds, E. Cook, Feb. 1995. Available at no charge from World Resources
Inst., 1709 New York Ave. NW, Washington DC 20006 (tel: 202 638 6300; fax: 202
638 0036).
These compounds, including perfluorocarbons and sulfur hexafluoride, have
atmospheric lifetimes of 3,200 to 50,000 years, and global warming potentials of
6,300 to 24,900 (compared to 1 for CO2). Emissions come primarily
from aluminum smelting, and the magnesium, electric utility and electronics
industries. Although their atmospheric concentrations are extremely low, their
use is growing. Because they do not deplete the ozone layer, some may view
perfluorinated compounds as a solution to one environmental problem; yet those
focused on climate change may view them as creating a different problem.
Item #d95may65
National
Environmental Indicator Series: Stratospheric Ozone Depletion. A State of
the Environment Bulletin from Environment Canada, Ottawa, ON K1A 0H3, Can.
Technical supplements are available.
Consists of a series of fact sheets, updated periodically. Recent examples
deal with explaining stratospheric ozone depletion as an issue; levels of new
supplies of ozone depleting substances; global atmospheric and stratospheric
concentrations of these compounds.

A Chemical
Disaster—Why HFCs Have No Future, Sep. 1994, $7.90/£5 Order from
Greenpeace U.K., Canonbury Villas, London N1 2PN, UK (tel: 44 71 3545100; fax:
44 71 6960012).
Criticizes the increased use of hydrofluorocarbons as substitutes for CFCs
because their global warming potential is up to 3,100 times that of CO2.
Accuses the Imperial Chemical Industries, the primary manufacturer, of
vigorously marketing HFCs, despite the existence of safer alternatives.
Item #d95may67
Climbing Out of
the Ozone Hole, 40 pp., Jan. 1994, $8. (Greenpeace—USA).
Item #d95may68
Money to Burn,
Oct. 1994. Contact Greenpeace Intl., Keizergracht 176, 1016 DW Amsterdam, Neth.
A critique of World Bank policies related to stratospheric ozone depletion
and the administration of the Montreal Protocol.
Item #d95may69
Potential Effect
of HFC Policy on Global Greenhouse Gas Emissions in 2035 (Rep. 773001002),
C. Kroeze, 29 pp., Sep. 1994. Contact Natl. Inst. Public Health & Environ.
Protect.-RIVM, POB 1, 3720 BA Bilthoven, Neth. (tel: 31 30 749111; fax: 31 30
742971).
Looked at the projected level of global emissions of HFCs in the year 2035,
and to what extent an HCFC phase-out could affect HFC emission. If HFCs are to
be used to replaced CFCs without restriction their global emissions will
increase to 1931 Mton CO2 equivalents; if they are also used as
substitutes for HCFCs, that level could be as high as 4665 Mton CO2
equivalents. Also suggests restriction to essential uses, avoidance of HFCs with
high global warming potential, better housekeeping, recycling, and restriction
to closed applications.
Item #d95may70
CFC Phaseout: An
Environmental Balancing Act, 4 pp., May 1994, $10 (EESI).
