Nitrous oxide (N2O) is an important GHG with a long atmospheric lifetime (approximately 120 years) and a global warming potential of 265 CO2-equivalents and contributes to ozone depletion. Therefore, N2O emissions (even at low levels) of a wastewater treatment system are relevant and increase severely their overall carbon footprint."engNitrous oxideWastewaterdoctoral thesis
