Data herein are presented for global-warming potentials of 25 g-CO2e/g for CH4 and 298 g-CO2e/g for N2O. Perhaps the most critical observation from the US-EIA data is that it is so coarse that only two domestic-wastewater Scope-1 GHG sources and electricity-related Scope-2 CO2 are included, specifically:

… Carbon dioxide is removed from the atmosphere (or "sequestered") when it is absorbed by plants as part of the biological carbon cycle. Methane (CH 4): Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic 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. During thawing, there was exponential relationship between CO2 fluxes and the soil temperature (5cm) (R2 = 0.912, p< 0.001). Meanwhile, CO2 fluxes was obviously correlated with the CH4 emission fluxes (R2 = 0.751, p < 0.001). The mires are N2O sink in winter and gradually become N2O source, with increasing temperature during thawing time.

0.5 0.0012. 0.009. 12.6. 0.03. emissions of CH4 and N2O are much lower, however, CO2 emissions are slightly time series in greenhouse gas emissions expressed as CO2 equivalents.

The annual GHG flux budget was dominated by N2O (48% contribution) and CO2 emissions (44%). CH4 flux contribution to the annual budget was only minor (8%). Carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) are key radiatively active greenhouse gases (GHGs) contributing to global warming (IPCC, 2001). The production and emission of these greenhouse gases have increased continuously since the pre-industrial era.

Methane’s 100-year GWP is about 28x CO2 – but it only persists in the atmosphere for a little more than a decade. 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.

This section provides information on emissions and removals of the main greenhouse gases to and from the atmosphere.
