Meet Emma Shen
Toronto, Ontario, Canada

An expert in wastewater treatment plant performance assessments and process upgrades evaluation, process modeling and energy optimization, Dr. Ruqiao (Emma) Shen leads a Jacobs team at the forefront of the global conversation about the paradigm shift toward a low-carbon, low-energy and climate-resilient water sector.
As Global Principal for wastewater energy optimization and sector decarbonization, Emma regularly presents at industry conferences, and she’s also the youngest and newest member of Jacobs’ global wastewater team.
Emma partners with clients to help identify projects that contribute to energy and carbon neutrality goals, and she’s been working with our global water resilience team to develop and implement climate change resilience assessments for water resource recovery facilities.
“I’ve spent my career working to advance the paradigm shift toward a low-carbon, low-energy and climate-resilient water sector. With the world placing an increased emphasis on climate change adaptation, the multi-dimensional aspects of and uses for wastewater are garnering attention as municipal utilities seek to become more sustainable.”
Emma holds a Ph.D. in civil engineering from the University of Toronto and a bachelor of environmental engineering from Tsinghua University. She’s the current vice chair for the Water Environment Foundation’s Greenhouse Gas (GHG) Focus Group under the Residual and Biosolids Community. Prior to her tenure at Jacobs, she was a postdoctoral research fellow at the University of Toronto’s drinking water research group.
Emma exemplifies the future of Jacobs and our mission, designing innovative water and wastewater solutions that will truly change our world.

Net-Zero Roadmap: How Water Resource Recovery Facilities Contribute to the Overall Decarbonization Strategy
In this “In the kNOW” webinar, we will explore the role of water resource recovery facilities (WRRF) in combating the climate emergency. The wastewater sector offers immense opportunities to contribute to climate goals. Two utilities – Metro Vancouver and VCS Denmark - will share their experience identifying and implementing measures to reduce emissions and achieve energy neutrality goals. We will also discuss the latest research on the quantification of nitrous oxide and methane emissions, considering global best science and the ambitions of the U.K. water sector as part of their 2030 net zero route map.
