Global nitrous oxide emissions
For global nitrous oxide (N2O) emissions, the dominating source is agricultural soils with smaller contributions from manufacturing industry and waste. We find relatively limited potentials to reduce future nitrous oxide emissions using existing technology, ranging from 6% ±2% for low cost options below 10 €/t CO2eq to maximum 26% ±9% for higher cost options. Given expected future increases in activities driving nitrous oxide emissions, also a full implementation of reduction measures will at best achieve a stabilization at the pre-2010 level.
