Monitoring, Modelling and Mitigating Methane in Wastewater – Masterclass 3

International Water Association Climate Change; Process Emissions; GHG; Global Warming, Methane

Target Audience

Professionals working in wastewater treatment who want to learn more about process or direct emissions and take steps to monitor and mitigate these


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 and a second masterclass on nitrous oxide, the third class will be dedicated to methane emissions in wastewater treatment.

It is increasingly important for water utilities to improve their understanding of methane 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 methane emissions. The class will bring participants up to speed with process emissions of 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  special guest utility experience from Anette Wästlund, Sjöstad WWTP Karlstad.

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

Learning Objectives

Following this webinar, participants will:

  • Understand the origins of methane formation and emission from wastewater sewers and treatment systems
  • Appreciate the state of knowledge globally to monitor and mitigate these
  • Understand how they can take action within their professional spheres to act to reduce these emissions
  • Understand where to find current science-base and emerging research.
