This webinar is part of a masterclass series organised by the IWA Climate Smart Utilities Initiative.  The goal of the Initiative is to assist water, wastewater, and urban drainage companies in improving their climate resilience by adapting to a changing climate while contributing to significant and sustainable reduction of GHG emissions.

After a first masterclass providing a general overview on Quantifying, modelling and mitigating process emissions (https://iwa-network.org/learn/process-emissions-masterclass-1/), the second masterclass will focus on nitrous oxide (N2O) , the third most important greenhouse gas and substantial contributor to global warming. Direct process emissions of nitrous oxide and methane are produced during the treatment of wastewater and sewage sludges.    It is increasingly important for water utilities to improve their understanding of N2O and reduce emissions as part of the Net Zero and green energy transition.   Whilst new approaches are continuously being developed in academia and industry,  much is already understood about how to quantify, model and mitigate these emissions. During this class, international experts in the field will present existing and recent approaches to quantify, monitor and mitigate N2O emissions.

During this class, international experts in the field will present existing and recent approaches to quantify, monitor and mitigate N2O emissions. The class will bring participants up to speed with process emissions of nitrous oxide and methane from wastewater treatment – through presentations of key findings from a newly launched IWA publication and by sharing the experiences of progressive utilities around the world.

This class is hosted and presented by editors and co-authors of the IWA publication “Quantifying and modelling of fugitive greenhouse gas emissions from urban water systems” along with guest utility SA Water.

This masterclass is supported and promoted by IChemE and their Water Special Interest Group.
