Report Highlights: Nitrous Oxide (N2O) Emissions:

  • N2O Significance: Third most significant greenhouse gas after CO2 and methane.
  • Climate Impact: Earth’s average surface temperature increased by 1.15°C due to greenhouse gasses.
  • Emission Trends: N2O emissions increased by 40% from 1980 to 2020.
  • Top Emitters: China, India, US, Brazil, Russia, Pakistan, Australia, Indonesia, Turkey, Canada.
  • Major sources: agriculture, industry, burning of forests/agricultural waste.
  • Atmospheric Concentration: N2O concentration in 2022: 336 parts per billion, 25% higher than 1850-1900 levels.
About Nitrous Oxide:

Chemical Formula: N2O

  • Colourless, non-flammable gas. Its vapors are heavier than air.
  • Induces euphoria, known as ‘laughing gas.’
  • Slightly sweet odor. It is soluble in water.
  • Acts as a powerful oxidizer at higher temperatures.

Applications:

  • Anesthetic and analgesic in medical procedures.
  • World’s leading inhaled anesthetic for pain relief.
  • Enhancing engine performance in the automotive industry.
