Water Nexus Registry

GHG Management & Energy Efficiency

Water agencies, suppliers, distributors and wastewater managers – as well as municipalities and businesses with large water footprints – can reduce their GHG emissions and become more energy efficient.

Guidance & Support

Access standardized guidance and metrics, an expert help desk, and an online reporting tool that will help you calculate and, if you choose, report the GHG emissions embedded in the water cycle.

Leadership & Recognition

Be recognized as a Water-Energy Leader™. This designation communicates that you are taking action on climate change — starting with tracking the GHGs connected to the water you deliver, treat, or use in your operations.


The Climate Registry (TCR) is pleased to release the Water Energy Nexus Registry Protocol Updates and Clarifications for public comment. A summary of the proposed changes is available here, and TCR is accepting comments on these changes until Monday, February 15.

Please join TCR for a webinar on Tuesday, February 2nd at 11:00am Pacific to launch the month-long public comment period. In this webinar, TCR will outline the updates and clarifications to the protocol, invite stakeholder feedback, and provide ample time for questions.

“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

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