Treating wastewater and sewage sludge produces direct greenhouse gas emissions, including methane and nitrous oxide, which have far greater warming potential than carbon dioxide. As society increasingly adopts renewable energy sources over fossil fuels, these emissions are expected to become the leading source of greenhouse gas emissions for wastewater utilities.

This expert-led webcast series is designed for wastewater professionals looking to deepen their understanding of greenhouse gas (GHG) emissions from wastewater treatment processes. Consisting of four one-hour sessions, the series will cover the types and sources of GHGs from wastewater treatment, the process conditions and mechanisms that drive these emissions, real-world approaches to measuring, monitoring, and quantifying these emissions, and practical strategies for reducing them.

Here are some resources, developed by Canadian Water Network, which include key takeaways from each webinar:

• Webinar 1: Fundamentals of wastewater process GHG emissions
• Webinar 2: Methane emissions from wastewater treatment
• Webinar 3: Nitrous oxide emissions from wastewater treatment
• Webinar 4: Opportunities for process emissions reduction

This series was organized by the US Water Alliance and Canadian Water Network, hosted by The Water Research Foundation, and presented in collaboration with the Danish Water Technology Alliance, Water Environment Federation, and the International Water Association.
