2.6–3.2 years atmospheric lifetime of methane — typical decay time in the atmosphere
Interpretation
Atmospheric Science Interpretation
From an atmospheric science perspective, methane’s relatively short 2.6 to 3.2 year lifetime means its air levels respond fairly quickly to changes in emissions and atmospheric chemistry rather than persisting for decades.

From an emissions inventories perspective, methane is a smaller share than CO2 in land use, with only 1.1% of global land use emissions attributed to methane, yet major inventory components such as waste contribute 21% of anthropogenic methane, underscoring how the biggest methane signals in reporting can come from specific sectors rather than from land use alone.
