Measuring Life Cycle Greenhouse Gas Emissions From Water Resource Recovery Facilities Workshop Report

Summary

The U.S. Department of Energy hosted a workshop in January 2024 to address the significant uncertainty in measuring greenhouse gas (GHG) emissions from water resource recovery facilities (WRRFs). The EPA's 2022 inventory estimates WRRF emissions at 44 million tons of CO2 equivalent, but current measurement methods and IPCC emission factors (last updated in 2019) are considered incomplete and inaccurate. The workshop explored challenges and opportunities for future DOE efforts, including potential measurement campaigns that could span 5-10 years and require funding between $5 million and $15 million, to inform mitigation strategies and support the national goal of net-zero emissions by 2050.
