CH₄/CO₂/H₂O Analyzer

Fast, Accurate Measurement for Soil Flux & Atmospheric Applications

Industrial Smoke

Why Measure CO₂ & CH₄?

Carbon dioxide (CO₂) is the primary greenhouse gas (GHG) emitted through human activities that accounted for 79% of all U.S. greenhouse gas emissions in 2021. Certain natural processes, industrial processes, and land-use changes also emit CO₂.


Methane (CH₄) is another GHG emitted through human activities, stemming from agricultural sources & livestock, land use, leaks from natural gas systems, and decay of organic waste (landfills). All of the above accounted for 12% of all U.S. GHG emissions in 2021. CH₄ lifetime in the atmosphere is much shorter than CO₂, but CH₄ is more efficient at trapping radiation. Pound for pound, the comparative impact of CH₄ is 28 times greater than CO₂ over a 100-year period. However, because CH₄ has a much shorter lifetime than CO₂, its mitigation has a direct and palpable environmental effect in the short-term.
