The 100-year GWP is used to derive CO 2 e. Nitrogen composition effects on CO2 emissions and CH4 uptake were independent of N input rates and measurement dates, but N2O emissions showed stronger responses to inorganic N under high N Total Emissions in 2018 = 6,677 Million Metric Tons of CO 2 equivalent.Percentages may not add up to 100% due to independent rounding. Larger image to save or print Gases that trap heat in the atmosphere are called greenhouse gases. This section provides information on emissions and removals of the main greenhouse gases to and from the atmosphere. These measurements show that the concentration of the three most important greenhouse gases (other than water vapour) CO 2, CH 4 and N 2 O have steadily increased during the past 250 years due to anthropogenic activities ( Prather and others, 2001; Prentice and others, 2001 ). To contribute towards an improvement of actual estimates, soil‐atmospheric CO 2, CH 4, and N 2 O fluxes were measured in three successional subtropical forests at the Dinghushan Nature Reserve (hereafter referred to as DNR) in southern China.

Yes, the answer is approximately 11.2 kg , but actually closer to 11.3 kg. Start with the balanced chemical equation. CH4+2O2→CO2+2H2O.

Releasing 1 kg of CH4 into the atmosphere is about equivalent to releasing 84 kg of CO 2.

Here we present evidence that the soils under alpine and sub-alpine snowpacks emit CO 2 and N 2 O and take up atmospheric CH 4 throughout the snow-covered period. These fluxes represent an Jianling Fan, Ruyi Luo, Brian G. McConkey, Noura Ziadi, Effects of nitrogen deposition and litter layer management on soil CO2, N2O, and CH4 emissions in a subtropical pine forestland, Scientific Reports, 10.1038/s41598-020-65952-8, 10, 1, (2020). 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 Simplified Expressions for Radiative Forcing of CO 2, CH 4, and N 2 O, Where C Is the CO 2 Concentration (in ppm), M Is the CH 4 Concentration (in ppb), and N Is the N 2 O Concentration (in ppb) a a C, M, and N are concentration at the time at which the forcing is required, and Co, Mo, and No are the initial concentrations. Of the three greenhouse gases that are exchanged by grasslands, CO 2 is exchanged with the soil and vegetation, N 2 O is emitted by soils and CH 4 is emitted by livestock at grazing and can be exchanged with the soil (Soussana et al., 2004).
