According to the EPA:
Methane (CH4) is a greenhouse gas that remains in the atmosphere for approximately 9-15 years. Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period and is emitted from a variety of natural and human-influenced sources.
Methane is one of several non-CO2 gases that contribute to global climate change. To learn more about these gases and what EPA is doing to reduce their impact, visit our Non-CO2 Gases page.
