2015-04-01 2003-12-01 When reporting CH4 and N2O emissions in tons of each respective gas, CH4 emissions should be reported with two decimal places and N2O emissions should be reported with three decimals places. After factoring in the GWP for CH4 and N2O, the emissions reported for each gas will have a precision on the same order as values reported for CO2 equivalents. THE ECONOMIC TRADE-OFF BETWEEN CO2, CH4 AND N2O ABATEMENT-AN ECONOMIC ASSESSMENT OF USING STATIC GWP'S. uregina.ca. Daniel Johansson. Download PDF. Download Full PDF Package. This paper.
However, biochar amendments increased overall GWP of CH4 and N2O gases. Since each greenhouse gas (GHG) has its own radiative capacity, all three gasses (CO2, CH4 and N2O) must be accounted for by calculating the net global warming potential (GWP) in a crop production system.

Often, we calculate GHG emissions in terms of how much CO 2 is essential to produce a similar warming effect over the chosen time horizon. The GWP was a positive number, because the GWP from N 2 O emissions was significantly higher than that from CH 4 uptake . Therefore, direct N 2 O emissions dominated the GWP of the saline–alkaline systems in this study. Adviento-Borbe et al. (2007) pointed out that soil N 2 O emissions were a major contributor to the GWP in eastern Nebraska, USA. The total GWP of CH4 and N2O gases were decreased by 7-27 % and 6-34 % with calcium carbide, phosphogypsum, and silicate fertilizer amendments under continuous and intermittent irrigations, respectively. However, biochar amendments increased overall GWP of CH4 and N2O gases.
Nitrous Oxide (N2O), 114, 298. 6 Feb 2013 Atmospheric concentrations of methane (CH4) and nitrous oxide (N2O) have the cumulative Global Warming Potential from CH4 and N2O.
Emissions are weighted according to the global warming potential of each gas. (GWP) the following weighting factors are used: CH4=25 and N2O=298,
Using each gas' individual global warming potential (GWP), they are being including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and the

See publication. Our “best estimate” of net GWP for CO2, CH4 and N2O fluxes was −0.50 ± 0.27 Pg CO2 eq/year (1 Pg = 1015 g) in North American terrestrial ecosystems during 2001–2010. The emissions of CH4 and N2O from terrestrial ecosystems had offset about two thirds (73 %±14 %)
N2O emission from CF was 18, 6.6 and 25 times as large as RG, RGCF and CK, respectively. Global warming potential (GWP) values calculated from CH4 and N2O emissions were in following order: RGRGCFCFCK (P0.05).
