The IPCC AR6 confirms that atmospheric methane concentrations are higher now than at any point in at least the last 800,000 years.

2H++2e−→H22 cap H raised to the positive power plus 2 e raised to the negative power right arrow cap H sub 2 ). The microbes then use this H2cap H sub 2 CO2cap C cap O sub 2 via the standard methanogenic pathway: metf ch4
: Ensuring that documents like Standard Operating Procedures (SOPs) are unambiguous and approved by authorized personnel. 5. Conclusion
Example: A landfill installing a new flare system reduces CH4 by 50,000 MTCO₂e annually. At $15/credit, that’s $750,000 in revenue — creating a financial incentive to go beyond compliance.
