equivalents).

carbon dioxide or the
equivalent amount of other greenhouse gases when measured in
terms of their potential to warm things up.]
Methane is roughly 84 - times worse than
carbon dioxide in the short (20 - year)
term, so EDF's counter translates methane emission to
carbon - dioxide
equivalent (CO2e), which is the standard measure of greenhouse gases.
(CO2e refers to the six Kyoto greenhouse gases —
carbon dioxide [CO2], methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride — all expressed in

equivalent amount of CO2.
One Gt is one gigatonne, a billion metric tons; CO2e,
carbon dioxide
equivalent, expresses the impact of different greenhouse gases in
terms of CO2.
«(A) the
term «destruction» means the conversion of a greenhouse gas by thermal, chemical, or other means to another gas or set of gases with little or no
carbon dioxide
equivalent value;
«(C) the
term «conversionary use» means the conversion during research or manufacturing of a fluorinated gas into another greenhouse gas or set of gases with a lower
carbon dioxide
equivalent value.
-- For purposes of this paragraph, the
term «destruction» means the conversion of a substance by thermal, chemical, or other means to another substance with little or no
carbon dioxide
equivalent value and no ozone depletion potential.
-- For practices or projects regulated pursuant to paragraph (2), the Secretary shall issue under section 507 a
term offset credit, in lieu of an offset credit, for each ton of
carbon dioxide
equivalent that has been sequestered.
In the Concise English Oxford Dictionary (July 2008), there is the
term «
carbon offsetting» which means «the counteracting of
carbon dioxide emissions with an
equivalent reduction of
carbon dioxide in the atmosphere».
-- The
term «
carbon dioxide
equivalent» means the unit of measure, expressed in metric tons, of greenhouse gases as provided under section 711 or 712.
The awarded projects — including 22 utility - scale solar farms, three wind farms and one hydroelectric project — are expected to create more than 3,000 short - and long -
term jobs, generate enough clean energy to power more than 430,000 homes and reduce
carbon emissions by more than 1.6 million metric tons, the
equivalent of taking nearly 340,000 cars off the road.
The Intergovernmental Panel on Climate Change (IPCC) estimates global anthropogenic greenhouse gas emissions for 1990 at 39.4 billion tonnes of
carbon dioxide
equivalent, suggesting that the Nigerian emissions may have represented approximately 0.09 % of the total in
terms of CO2 and 0.76 % of the total in
terms of methane, using the IPCCs 100 - year global warming potential for methane of 25.
Here is my explanation of the background to these figures and the
term «
carbon dioxide
equivalents» (Nb.
Article 3 of the Kyoto Protocol states targets for emissions reductions in
terms of «aggregate anthropogenic
carbon dioxide
equivalent emissions of the greenhouse gases listed in Annex A.» Using this approach, Australia's net greenhouse gas emissions across all sectors in 2004 totalled 564.7 million tonnes of
carbon dioxide
equivalent.
However, the use of this
term is not uniform when discussing stabilisation targets as some authors define
carbon dioxide
equivalent concentrations as the net forcing of all anthropogenic radiative forcing agents including greenhouse gases, tropospheric ozone, and aerosols but not natural forcings.
RealClimate gives a good explanation of
carbon dioxide
equivalents when used in
terms of atmospheric concentrations rather than emissions at http://www.realclimate.org/index.php/archives/2007/10/co2-

equivalent to 10 °C per century could be sufficient to trigger compost - bomb instability in drying organic soils Wiley: First generation climate —
carbon cycle models suggest that climate change will suppress
carbon accumulation in soils, and could even lead to a net loss of global soil
carbon over the next century.
Specifically, the
term is defined as how much the average global surface temperature will increase if there is a doubling of greenhouse gases (expressed as
carbon dioxide
equivalents) in the air, once the planet has had a chance to settle into a new equilibrium after the increase occurs.
