WUCA recognizes the importance of greenhouse gas (GHG) mitigation as a key climate adaptation strategy and an issue of climate leadership in the water sector.

Ultimately, the more GHG emissions are mitigated, the less water utilities will need to adapt. Therefore, a key objective in WUCA's 2022-2026 Strategic Plan is for the alliance to continue developing practical examples and case studies of climate adaptation and climate mitigation. Water utilities have a unique role to play in mitigating GHGs, both due to the high energy usage of the water industry as well as the leading example that the water industry sets for other industries and business communities.

These GHG mitigation case studies are examples of progressive GHG mitigation projects at water utilities and include lessons learned during implementation. The selection of case studies is designed to represent a wide swath of project types—it is not an exhaustive list but hopefully a strong starting point for utilities to learn from each other. The focus was on water supply utilities, but many of the projects can be equally applied at wastewater and stormwater utilities.

The case studies were developed in partnership with the utilities profiled, and contacts are provided in each case study to facilitate follow-up and enable interested readers to learn more about implementing similar projects.
