Understanding these impacts and the regulatory landscape surrounding N₂O emissions is crucial for developing effective mitigation strategies.

N₂O's Role in Climate Change

N₂O is a long-lived greenhouse gas, meaning it persists in the atmosphere for extended periods, contributing to long-term climate forcing. Its global warming potential (GWP) is significantly higher than that of carbon dioxide (CO₂), the most abundant anthropogenic greenhouse gas. The Intergovernmental Panel on Climate Change (IPCC) estimates N₂O's GWP to be 265–298 times that of CO₂ over a 100-year period.

This elevated GWP implies that even relatively small emissions of N₂O can have a disproportionately large impact on global warming. N₂O absorbs infrared radiation emitted from the Earth's surface, trapping heat and contributing to the overall warming of the planet. Its atmospheric concentration has steadily increased since the pre-industrial era, primarily due to human activities.
