Global Climate Change Digest
A Guide to Information on Greenhouse Gases and Ozone Depletion
Published July 1988 through June 1999
FROM VOLUME 6, NUMBER 11, NOVEMBER 1993
EPA series: The
following have been produced by the U.S. Environmental Protection Agency in
response to requirements of the 1990 Clean Air Act Amendments, and are available
from the Global Change Div. (6202J), U.S. EPA, 401 M St. SW, Washington DC 20460
Anthropogenic Methane Emissions in the United States: Estimates for 1990
(EPA 430-R-93-003), 260 pp., Aug. 1993. Presents detailed estimates for
emissions from the natural gas system, coal mining, landfills, livestock and
Current and Future Methane Emissions from Natural Sources (EPA
R-93-011), 126 pp., Nov. 1993. Gives global estimates of emissions from those
natural systems most likely to be sensitive to climate change; i.e., wetlands,
gas hydrates and permafrost.
Opportunities to Reduce Anthropogenic Methane Emissions in the United
States (EPA 430-R-93-012), 382 pp., avail. soon. Evaluates options for
reducing emissions and estimates the portion of current and future emissions
that could be reduced.
Options for Reducing Methane Emissions Internationally. Vol 1:
Technological Options... (EPA 430-R-93-006), 265 pp.; Vol. 2:
International Opportunities... (EPA 430-R-93-006B), 215 pp. Avail. soon.
Describes the most promising international options through technologies that are
in use or under development.

member /£30 nonmember countries of IEA Coal Res. Assesses methods for
Methane Emissions from Livestock: Biological and Nutritional Controls
(NASA-CR-191354), D.E. Johnson (Colo. State Univ., Ft. Collins), 80 pp., Oct.
1992. NTIS: N93/15480/5; $19.
Compiled an extensive database of measurements primarily on cattle and
sheep, which indicates influences of husbandry, diet, physiological state etc.
However, little experimental data is available for two-thirds of the world's
ruminants in developing countries.
Development of an
Empirical Model of Methane Emissions from Landfills (EPA/600/R-92/037), R.L.
Peer et. al. (Radian Corp., Res. Triangle Pk., N.C.), 1992. NTIS: PB92-152875;
Regression analysis of measurements from 21 U.S. landfills showed that depth
was the best predictor of emissions, with refuse mass second; much variability
in methane recovery remained unexplained. Proposes a model.
