A Guide to Information on Greenhouse Gases and Ozone Depletion
Published July 1988 through June 1999
FROM VOLUME 6, NUMBER 10, OCTOBER 1993
"Future Emissions of CH4 from the Natural Gas and
Coal Industries," Energy Policy, 21(8),
827-830, Aug. 1993.
Using a simple model (relating fuel use to national
population) and published loss rates of CH4 from the
natural gas industry and coal mining, estimates annual increases
of CH4 of 0.7-0.9% (natural gas) and 0.6% (coal
mining) through 2025.
Estimate of the Anthropogenic Contribution to Atmospheric Methyl
Bromide," C.E. Reeves (Sch. Environ. Sci., Univ. E. Anglia,
Norwich NR4 7TJ, UK), S.A. Penkett, Geophys. Res. Lett., 20(15),
1563-1566, Aug. 6, 1993.
The best estimate from a global, 2-D atmospheric chemistry
model employing a prescribed OH field is a global emission of 91
kt yr-1, with a 54% anthropogenic contribution.
Hydroelectric Reservoirs Significant Sources of Greenhouse
Gases?" J.W.M. Rudd (Freshwater Inst., 501 Univ. Crescent,
Winnipeg, Man. R3T 2N6, Can.), R. Harris et al., Ambio, 22(4),
246-248, June 1993.
Two studies by the authors indicate that, compared to
fossil-fuel electricity generation, some reservoirs may be
significant emitters of greenhouse gases, depending on the extent
of flooding and other physical, chemical and biological features.
"Estimating Greenhouse Gas Emissions from Fossil Fuel
Consumption: Two Approaches Compared," D. von Hippel (Tellus
Inst., 89 Broad St., Boston MA 02110), P. Raskin et al., Energy
Policy, 21(6), 691-702, June 1993.
New results for 1988 CO2 emissions vary by more
than 10% from the Oak Ridge National Laboratory's estimates, for
52 of the 139 countries compared. Among the differences between
the calculations are the inclusion here of estimates of CO, CH4
and N2O from fossil fuel combustion, which together
add a global heating effect of about 8% of the CO2
"Atmospheric Sulfur Hexafluoride: Sources, Sinks and
Greenhouse Warming," M.K.W. Ko (Atmos. & Environ. Res.
Inc., 840 Memorial Dr., Cambridge MA 02139), N.D. Sze et al., J.
Geophys. Res., 98(D6), 10,499-10,507, June 20, 1993.
Discusses commercial applications of SF6 and derives a global
emission rate from an estimate of worldwide production.
Determines an atmospheric lifetime using several approaches.
"Automotive Tire Wear as a Source for Atmospheric OCS and
CS2," W.H. Pos (Sch. Earth & Atmos. Sci., Georgia Inst.
Technol., Atlanta GA 30332), Geophys. Res. Lett., 20(9),
815-817, May 5, 1993.
Laboratory experiments show that tire wear may provide as much
as 6.7% of the total OCS flux to the atmosphere, making a small
but significant contribution to its global budget.
Compilation of Inventories of Emissions to the Atmosphere,"
T.E. Graedel (AT&T Bell Labs., Murray Hill NJ 07974), T.S.
Bates et al., Global Biogeochem. Cycles, 7(1),
1-26, Mar. 1993.
Compiles existing inventories and their characteristics as a
contribution toward providing internationally recognized emission
inventories suitable for global and regional modeling. The CFC
inventory is the only good one; those for CO2, CH4,
NOx, SO2 and reduced S are fair. The spatial
resolution for some gases in selected regions is well determined,
but temporal resolution is almost universally poor.
from Appl. Energy, 44(2), 1993:
"Forecasting Landfill-Gas Yields," N. Gardner
(Environ. Resour. Ltd., Units 1-2, Enterprise Pk., Boughton Green
Rd., Northampton NN2 7AH, UK), S.D. Probert, 131-163. Reviews
models for predicting landfill gas output and compares
calculations from one model to observations. Makes
recommendations for model improvement.
"Gas Emissions from Landfills and Their Contributions to
Global Warming," N. Gardner (addr. immed. above), B.J.W.
Manley, J.M. Pearson, 165-174. Describes a method for assessing
the amount of landfill gas emitted, and its application in the
field to predict potential gas yield from sites in the U.K.
Examines the economic viability of utilizing landfill gas,
finding the approach to have advantages.
