Nitrous Oxide (N2O)

Nitrous oxide (N₂O) is an odorless, colorless, non-flammable gas that significantly contributes to global warming. It is emitted from various sources, including agricultural activities (such as soil management and fertilizer application), land use practices, industrial processes, combustion of fossil fuels and solid waste, and wastewater treatment.

Key aspects of nitrous oxide include:

• Potent Greenhouse Gas: N₂O has a global warming potential approximately 300 times that of carbon dioxide (CO₂), making it a significant contributor to climate change.
• Long Atmospheric Lifetime: Nitrous oxide remains in the atmosphere for an average of 114 years, allowing it to have a prolonged impact on global warming.
• Ozone Depletion: In addition to its greenhouse effect, N₂O contributes to the depletion of the stratospheric ozone layer, which protects the Earth from harmful ultraviolet radiation.

Mitigating nitrous oxide emissions is crucial for addressing climate change and protecting the ozone layer, necessitating sustainable agricultural practices, improved industrial processes, and effective waste management strategies.
