India is the world’s second largest source of nitrous oxide (N2O).
N2O is a greenhouse gas that heats up the atmosphere far more than carbon dioxide.
Nearly 11% of such global man-made emissions in 2020 were from India, topped only by China at 16%.
The major source of these emissions comes from fertiliser usage.
N2O emissions from human activities have increased by 40% (three million metric tons of N2O per year) in the past four decades.
The top five country emitters by volume of anthropogenic N2O emissions in 2020 were China (16.7%), India (10.9%), the United States (5.7%), Brazil (5.3%), and Russia (4.6%).
