Atmospheric & Biogeochemical CyclesAgricultureThis quantity is a single measurement of the quantity at a given point in time (2000 – 2010).
Value: | ≈ 0.25 kg CO2e / Mcal | |
HuID: | 74420 | |
Relevant Year(s): | 2000 – 2010 | |
Summary: | Mass of greenhouse gas (in CO2 equivalents) emitted per megacalorie of wheat. Greenhouse gases considered are CO2, CH4, and N2O. See Fig. 2(C) of source for more information. | |
Method: | One CO2 equivalent is defined as the mass of CO2 that would have to be emitted to match the 100-year global warming potential of the gas under consideration. For example, one kg of CH4 has the same 100-year global warming potential of emitting 25 kg of CO2.
No uncertainty estimate is reported for this quantity and should thus be taken as an approximate value. |
