 Nitrous oxide (N2O) is a greenhouse gas with an atmospheric
lifetime of approximately 120 years. Nitrous oxide is about
310 times more effective in trapping heat in the atmosphere
than CO2 over
a 100-year period. The primary sources of human-influenced
emissions of nitrous oxide
are agricultural soil management, animal manure management,
sewage treatment, mobile and stationary fuel
combustion, adipic acid production,
and nitric acid production. Nitrous oxide is also emitted
naturally from a wide variety of biological sources.
Nitrous Oxide 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. |
