Figures 4.1 and 4.2). Emissions of CH4 and N2O due to human. 1 Dec 2014 CH4 and N2O emissions rates can be converted to CO2 equivalents using the ' 100-yr global warming potential' factors as follows: 1 kg N2O 3.1 gigatonnes CO2-eq of CH4 per annum, or. 44 percent of anthropogenic CH4 emissions.

We explain all you need to know about the main greenhouse gases, including water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), the fluorinated gases (CFCs, HCFCs, HFCs, PFCs) and ozone (O3). Power station emits greenhouse gases. So, even though CO2 is causing the most warming on a pound-for-pound basis, reductions in CH4 or N2O emissions provide a lot more climate relief than those of CO2. For example, reducing methane emissions by one ton would be equivalent to reducing CO2 emissions by 25 tons; thus, its CDE is 25 tons. In the case of N2O, its CDE is 298 tons of CO2. CH 4 emission = Fossil fuel consumption in volume unit X CH 4 emission factor (Ton per volume unit) N 2 O emission = Fossil fuel consumption in volume unit X N 2 O emission factor (Ton per volume unit) Total GHG emission (in tCO 2 eq) = (CO 2 emission) + (CH 4 emission X 21) + (N 2 O emission X 310) CO 2 emission = 100 X 0.00265; CH 4 emission = 100 X 0.00000036 Carbon dioxide: CO 2: 1: 1: Methane: CH 4: 21: 25: Nitrous oxide: N 2 O: 310: 298: Sulphur hexafluoride: SF 6: 23 900: 22 800: Nitrogen trifluoride: NF 3-17 200 CH4 and N2O emissions rates can be converted to CO2 equivalents using the ‘100-yr global warming potential’ factors as follows: 1 kg N2O = 298 kg CO2 equivalents 1 kg CH4 = 25 kg CO2 equivalents In general, CO2 emission rates are combined with emission rates for CH4 and N2O to obtain the CO2e emission rate of a fossil fuel. Some basic conversions between energy units may also be included (e.g., BTU to therm) in the calculations. CO2: 1; Methane (CH4): 21; Nitrous oxide (N2O): 310; Based on weight and a 100-year period, methane is thus a 21 times more powerful greenhouse gas than CO2 and N2O is 310 times more powerful.

Q322. To what precision should emission values for CO2, N2O, and CH4 be reported in e-GGRT? A322. All CO2 and CO2 equivalent values should be reported with precision to the nearest ton. When reporting CH4 and N2O emissions in tons of each respective gas, A CO2-equivalent out of wetland soil, but the substrates for methane flux for a 1-kg CH4 or N2O flux is the mass of CO2 production are primarily plant-derived C (e.g., root exu- emissions that would generate the same integrated radiative dation, deposition, and respiration CO2) [Watanabe et al., forcing, over the chosen time horizon, as a 1-kg emission 1999; Lu et al., 2002; King et al., 2002 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. To compare the impact of GHG fluxes from the rice growing and the fallow season on the annual gas fluxes, and their contribution to the GWP and carbon sequestration (CS) were evaluated.

CH4 flux contribution to the annual budget was only minor (8%).
