Greenhouse Gas Protocol Dual Reporting Report for Knowit

Nitrous oxide (N2O) has a value of 310. This means that a gram of methane has the same effect as 21 grams of CO2. 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. The CH 4 GWP also accounts for some indirect effects, such as the fact that CH 4 is a precursor to ozone, and ozone is itself a GHG. Nitrous Oxide (N 2 O) has a GWP 265–298 times that of CO 2 for a 100-year timescale. N 2 O emitted today remains in the atmosphere for more than 100 years, on average. Methane's lifetime in the atmosphere is much shorter than carbon dioxide (CO 2), but CH 4 is more efficient at trapping radiation than CO 2. Pound for pound, the comparative impact of CH 4 is 25 times greater than CO 2 over a 100-year period. 1 2013 Revisions to the Greenhouse Gas Reporting Rule (PDF) to 40 CFR part 98, subpart C: Table C–1 to Subpart C—Default CO2 Emission Factors and High Heat Values for Various Types of Fuel and Table C–2 to Subpart C—Default CH4 and N2O Emission Factors for Various Types of Fuel.

Pound for pound, the comparative impact of CH 4 is 25 times greater than CO 2 over a 100-year period. 1 2013 Revisions to the Greenhouse Gas Reporting Rule (PDF) to 40 CFR part 98, subpart C: Table C–1 to Subpart C—Default CO2 Emission Factors and High Heat Values for Various Types of Fuel and Table C–2 to Subpart C—Default CH4 and N2O Emission Factors for Various Types of Fuel. 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.
