Water Nexus Registry

Efficiency & GHG Management

The Water-Energy Nexus Registry helps water agencies, suppliers, distributors and wastewater managers, as well as municipalities and businesses with large water footprints, become more energy efficient, reduce greenhouse gas emissions, and show their climate leadership.

Guidance & Support

Participants use standardized guidance and metrics and an online reporting tool to annually report the GHG emissions embedded in the extraction, consumption, delivery, storage, and treatment of water.

For Organizations in California

Sponsored by the California Environmental Protection Agency (CalEPA) and administered by The Climate Registry, the Water-Energy Nexus Registry welcomes all organizations with operations in the Golden State.

We recognize the Water-Energy Nexus Registry Founders for their outstanding leadership.

“The Water-Energy Nexus Registry may become an important tool for water agencies, cities, agriculture, colleges, and other large water users. My hope is that this will become one more solution to meeting our 2030 climate pollution reduction targets.”

– Fran Pavley, Former California State Senator and Environmental Policy Director for the USC Schwarzenegger Institute
