Abstract: Greenhouse gas emissions particularly CO2, CH4, and N2O are increasing due to human activity and causing climate change. Wastewater treatment plants are a significant emitter of GHG’s and there are opportunities to reduce them. Quantification of GHG generation and emissions are necessary to target reductions. Emission factor estimates are the common approach recommended by regulatory agencies across the world. As our understanding of the mechanisms behind GHG generation increase, the ability to accurately model emissions is now a feasible approach and promises to be more accurate. This main objective of this research was to compare GHG emissions from whole plant modeling to an emission factor approach. Models, steady state and dynamic, were simulated under various operational conditions to quantify emissions from the bioreactors. It was found that a CO2 emission factor could estimate emissions accurately, while a modeling approach was better suited for CH4 emissions, and essential for N2O emissions.
