Table 1.

Quantities and global warming impacts of CH₄ and N₂O emissions in WWTPs.

Reference	Inventory	Quantity^a (g CO₂ m⁻³)	Global Warming Impact^b (g CO₂ m⁻³)	Data Source
[16]	CH₄	11.36	284	Measurement
[16]	N₂O	1.83	546	Measurement
[18]	CH₄	2.40	60	Simulation
[18]	N₂O	0.81	240	Simulation
[20]	CH₄	2.384	59.6	Simulation
[20]	N₂O	0.479	142.6	Simulation

The quantity values refer to the wastewater flow rate.

Global warming potential: 25 kg CO₂ per kg CH₄ for CH₄ and 298 kg CO₂ per kg N₂O for N₂O.
