The bill requires the California Environmental Protection Agency (CalEPA) to oversee development and administration of a voluntary registry that tracks greenhouse gas emissions arising from the water–energy nexus using best-available data. Any entity doing business in California may participate, register emissions on an entitywide basis (including emissions generated outside the state), and access registry services.
CalEPA may contract with a qualified nonprofit to build the registry through a public stakeholder process, provide technical support (workshops, trainings, baseline-setting), enable third-party-verified, consistent reporting, publicize voluntary reductions, and recruit participation across sectors. The contract is limited to three years and a total budget of $2,000,000, with a one-year extension allowed by mutual agreement.
The measure positions the registry as a voluntary tool to improve accounting and efficiency but relies on a single, time-limited contractor and constrained funding.
At a Glance
What It Does
Directs CalEPA to oversee a voluntary registry for greenhouse gas emissions tied to the water–energy nexus and authorizes a contract with a qualified nonprofit to design and run the registry, provide participant services, and align accounting with existing California methodologies.
Who It Affects
Targets water agencies, municipal and investor-owned utilities, agricultural water users, energy providers, large corporate water users, third-party verifiers, technical vendors, and environmental NGOs that track or seek to reduce water‑related emissions.
Why It Matters
Creates a state-backed, voluntary mechanism to standardize how water‑related emissions are measured and reported, potentially enabling consistent baselines and verified reductions; however, voluntary participation and limited contract resources may constrain statewide coverage and influence.

What This Bill Actually Does
The bill asks CalEPA to start and run a registry specifically focused on greenhouse gases that arise because of interactions between water and energy systems — the so-called water–energy nexus. Participation is voluntary and wide open: any business operating in California can sign up and may submit an entitywide inventory that includes emissions produced outside California.
The registry is designed as a services platform, not a regulatory permitting program: it will help entities set baselines, record voluntary reductions, and publicize those efforts.
Rather than build the registry entirely in-house, CalEPA can hire a qualified nonprofit to design and administer it. The contract requires the nonprofit to develop the system through a public stakeholder process and to consult other state agencies; it also directs consideration of greenhouse gas accounting methods already developed under California’s Global Warming Solutions Act.
Practically, that means the registry will attempt to align with existing state accounting approaches while tailoring tools and guidance to water-related emissions.On the participant side, the registry must support third-party verification, provide technical assistance (training, workshops, and reporting help), and recruit broadly across regions and sectors. The bill explicitly allows the registry to streamline reporting for entities already using The Climate Registry’s voluntary corporate program, aiming for interoperability rather than duplicate inventories.
Because the statute makes participation voluntary and places a three-year, $2,000,000 limit on the contractor, the registry’s initial scope will likely depend on how many organizations sign up and how the contractor prioritizes services.
The Five Things You Need to Know
Participation is voluntary and open to any entity doing business in California, but entities may submit entitywide emissions totals that include emissions generated outside the state.
The nonprofit contractor must develop the registry through a public stakeholder process and consider greenhouse gas accounting methodologies created under the California Global Warming Solutions Act (Division 25.5, commencing with Section 38500 of the Health and Safety Code).
Registry functions explicitly include establishing participant baselines, enabling third‑party verification of voluntary reductions, providing technical support (workshops and trainings), and recognizing entities that reduce water‑related GHG intensity.
CalEPA’s contract with the qualified nonprofit is capped at three years and a total budget of $2,000,000, with a possible one‑year extension if both parties agree.
The registry must facilitate streamlined reporting for entities already reporting to The Climate Registry’s voluntary corporate GHG program, signaling an intent for data interoperability rather than parallel inventories.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
CalEPA oversight of a water–energy GHG registry
This clause assigns CalEPA responsibility for overseeing development and administration of a registry focused on greenhouse gases tied to the water–energy nexus and requires use of the best‑available data. For practitioners, that means CalEPA sets policy parameters and governance for the registry, deciding standards, stakeholder engagement approaches, and which datasets qualify as "best‑available." The oversight role gives the agency discretion over technical design and public framing without creating a regulatory emissions cap.
Voluntary, entitywide participation with out‑of‑state emissions
Participation is explicitly voluntary and open to any entity doing business in California; participants may register emissions on an entitywide basis and include emissions generated outside California. That design raises practical accounting issues: registrants will need clear guidance on geographic and operational boundaries, consolidation methods (equity vs. control), and how to avoid double‑counting where multiple registries or jurisdictions overlap.
Nonprofit contract to build the registry and consult state agencies
CalEPA may contract with a qualified nonprofit to develop the registry via a public stakeholder process and to consult other state agencies. The statute requires the contractor to consider existing greenhouse gas accounting methodologies from programs created under California’s Global Warming Solutions Act, which steers the registry toward alignment with state norms for inventorying emissions. The nonprofit model centralizes technical work in a hired organization rather than creating a state bureau; procurement, conflict‑of‑interest safeguards, and contractor qualifications will be critical to credibility.
Participant services: baselines, verification, outreach, and recognition
The contract tasks the nonprofit with helping participants set baselines, encouraging efficiency actions, enabling consistent entitywide reporting backed by third‑party verification, publicizing voluntary reductions, and recruiting a broad range of participants. Operationally, the contractor will need to design baseline methodologies, vet verification protocols, run outreach to diverse sectors, and create mechanisms for public recognition — each activity has cost, staffing, and data‑management implications.
Data‑reporting interoperability with The Climate Registry
The bill directs facilitation of streamlined reporting for entities already using The Climate Registry’s voluntary corporate GHG program. This provision targets interoperability: the contractor must design data flows or templates to reduce duplicate reporting burdens, which requires technical mapping between programs’ data schemas and agreement on which metrics can be ported without rework.
Contract term, budget cap, and limited extension
The statute caps the nonprofit contract at three years and $2,000,000, with a one‑year extension available only by mutual consent. That creates a fixed window and budget to launch the registry, which shapes the contractor’s prioritization: early deliverables likely include stakeholder engagement, an initial technical framework, and pilot reporting tools rather than a fully scaled, long‑term data platform.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Regional water utilities and municipal water districts — they gain a standardized way to measure water‑related emissions, technical support to set baselines and seek efficiency gains, and a mechanism to publicize verified reductions.
- Large corporate water users and investor‑owned utilities — the registry lets them report entitywide emissions (including out‑of‑state operations) in a state‑aligned format and potentially claim verified improvements that may help with investor or customer transparency demands.
- Environmental and conservation NGOs — they obtain better, centralized data on the water–energy nexus, improving policy analysis and advocacy around efficiency and emissions reduction opportunities.
- Technical vendors and third‑party verifiers — demand for verification services, reporting software, and consulting will grow as participants seek credible, consistent inventories.
- The Climate Registry and similar voluntary frameworks — interoperability requirements make it easier for their participants to transact data with a California state‑backed registry, increasing the value of cross‑program comparability.
Who Bears the Cost
- Participating entities — they must allocate staff time and budget for data collection, apply accounting rules, and pay for third‑party verification where required or desired.
- Small and rural water providers — limited internal capacity makes baseline development and verification disproportionately costly, raising barriers to participation without subsidies or targeted assistance.
- CalEPA — although the nonprofit contract funds registry development, the agency will carry oversight, stakeholder coordination, and continuation decisions without explicit additional funding beyond the contract cap.
- Qualified nonprofit contractor and service providers — tasked with extensive stakeholder engagement, technical development, and outreach within a tight three‑year, $2M budget, creating pressure to prioritize limited deliverables.
- The Climate Registry and other existing reporters — may incur technical mapping or process changes to enable streamlined reporting, requiring coordination work and possible system adjustments.
Key Issues
The Core Tension
The central dilemma is credibility versus accessibility: the bill aims to produce rigorous, third‑party‑verified accounting for water‑related emissions (which requires detailed protocols and verification costs) while also keeping the program voluntary and inexpensive to run — a combination that may limit participation by the organizations whose behavior change is needed to lower statewide emissions.
The statute creates a voluntary, service‑oriented registry rather than a regulatory inventory, and that design produces trade‑offs. Voluntary participation lowers legal obstacles and can attract early adopters, but it also risks limited coverage and selection bias: organizations that self‑select may already be relatively low‑carbon or well resourced, reducing the registry’s ability to reveal statewide mitigation opportunities.
The law’s allowance for entitywide reporting that includes out‑of‑state emissions improves completeness for some firms but raises double‑counting and boundary issues that the contractor will need to resolve through clear protocol choices.
Relying on a single nonprofit contractor to assemble technical guidance, verification protocols, outreach, and interoperability features concentrates both authority and risk. The statute requires alignment with methodologies from the Global Warming Solutions Act, which helps technical credibility but leaves open which specific protocols (scope definitions, allocation methods, indirect emissions rules) the registry will adopt.
The three‑year, $2,000,000 contract cap is modest for building durable data platforms, running broad stakeholder processes, and subsidizing participation for resource‑constrained entities; expect prioritization decisions that may exclude deeper functionality or long‑term data stewardship. Finally, the bill does not create enforcement mechanisms, financial incentives, or mandatory reporting — so the registry’s climate impact depends on voluntary uptake, the perceived credibility of third‑party verification, and whether buyers, regulators, or investors place value on registry outputs.
