Cumulative nitrous oxide emissions in selected countries worldwide 1851-2021
The United States is the largest nitrous oxide (N2O) emitter in history, having released the equivalent of 25.5 billion metric tons of carbon dioxide (GtCO2e) since 1850. The countries that make up the European Union (EU-27) rank second, with cumulative emissions of 24.7 GtCO2e. Combined, Germany and France account for more than one-third of historical nitrous oxide emissions from EU-27 countries. While China is the third-largest N2O emitter historically, it is now the biggest nitrous oxide emitter annually.
Nitrous oxide is a powerful greenhouse gas with a global warming potential 300 times greater than carbon dioxide.
