India Is World’s Second Largest Emitter Of Nitrous Oxide

India is the world’s second largest source of nitrous oxide (N2O), 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, according to a global assessment of N2O emissions published in the journal Earth System Science Data on June 12.
