Carbon dioxide equivalent (CO 2 e or CO 2 eq or CO 2-e) is calculated from GWP. It can be measured in weight or concentration. For any amount of any gas, it is the amount of CO 2 which would warm the earth as much as that amount of that gas. Thus it provides a common scale for measuring the climate effects of different gases.

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. 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).

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. -------f These potentials1 are: GWP Carbon dioxide (CO2) 1 Methane (CH4) 21 Nitrous oxide (N2O) 310 Hydrofluorocarbon (HFC)-134a (used in mobile source air conditioning) 1,300 Carbon dioxide equivalents vs.

For example, methane (CH4) is often given a GWP of x21 and nitrous oxide (N2O) a GWP of x310. So if each tonne of these gases is multiplied by its GWP and added to the CO2 gas total, the result will be total CO2e. Please note that the numbers may not add up precisely due to minor rounding present in the summary table.

The idea is to express the impact of each different greenhouse gas in terms of the amount of CO2 that would The emissions of CH4 and N2O are related to vehicle miles traveled rather than fuel consumption, and the emissions of CH4, N2O, and HFCs are not as easily estimated from a vehicle as for CO2.3 On average, CH4, N2O, and HFC emissions represent roughly 5-6 percent of the GHG emissions from passenger vehicles, while CO2 emissions account for 94- 95 percent, accounting for the global warming 2017-03-19 · A word about nitrous oxide. N2O is a strong greenhouse gas (GHG) with about the same stability in the atmosphere as carbon dioxide (CO2). Because of this similar lifetime, N2O is always about 230x to 270x as bad as CO2 (per kg) whatever time period or schedule you are considering (unlike methane*). ----- These potentials1 are: GWP Carbon dioxide (CO2) 1 Methane (CH4) 21 Nitrous oxide (N2O) 310 Hydrofluorocarbon (HFC)-134a (used in mobile source air conditioning) 1,300 Carbon dioxide equivalents vs.
