Nitrous Oxide (N2O)

N2O has a global warming potential of 298, indicating emission of one gram of N2O is equivalent to 298 grams of CO2. N2O accounts for 3.1% of 2017 statewide GHG emissions in CO2 equivalent units.

Sources of N2O in California

Agriculture accounts for the majority of N2O emissions, primarily from fertilizer and manure added to soil. Commercial and residential use of nitrogen fertilizer on turf and transportation are also important sources of N2O. Industrial sources of N2O include solid waste and wastewater treatment, manufacturing, refining and other sources.
