AB1086 directs the California Air Resources Board (state board) to create a Marine Carbon Initiative made up of a Marine Carbon Council and a Marine Carbon Research Program. The council must map scientific gaps across a set list of marine carbon dioxide removal and sequestration approaches, recommend testing scales and ecosystem metrics, and advise state agencies.
The program will competitively fund field studies and demonstrations that include California-based partners or personnel.
Why it matters: the bill builds a state-level technical and funding pathway for in‑ocean carbon removal research, explicitly requires cross-agency coordination and public reporting, and conditions commercial pathways on evidence developed through piloting and MRV (measurement, reporting, verification). The initiative would concentrate early-stage experimentation in California waters while leaving key permitting and regulatory authorities intact.
At a Glance
What It Does
The state board must stand up a seven-member Marine Carbon Council by mid-2027 and create a Marine Carbon Research Program by August 1, 2028. The council identifies research gaps, metrics, and safe testing scales for a menu of approaches (e.g., alkalinity enhancement, macroalgae cultivation, mineralization) and the program awards competitive grants and other financial incentives to eligible projects with California partners or residents.
Who It Affects
Academic and federal laboratories, private developers of marine carbon technologies, coastal economies (fishing, aquaculture, recreation), and multiple state permitting agencies that must be consulted or receive research findings. Organizations seeking program funding must have California-based partners or staff.
Why It Matters
AB1086 creates a formal, state-led mechanism to enable controlled in-ocean testing and to develop MRV standards and commercialization pathways. It also authorizes an annual appropriation (the bill specifies $2 million per year for at least seven years, subject to appropriation) and mandates annual project updates and biennial legislative reports—concentrating early decision-making about ocean carbon in California institutions.

What This Bill Actually Does
AB1086 defines two linked but distinct tracks: a scientific advisory body (the Marine Carbon Council) and an implementation vehicle (the Marine Carbon Research Program). The council’s job is to scope what we know and do not know about a roster of marine carbon dioxide removal (MCDR) and sequestration techniques, recommend how to measure and verify outcomes, and propose safe, limited scales for field testing so regulators and communities can assess risks and benefits.
The council will be appointed by the state board (seven members) after a public nomination process and must represent a range of expertise—chemistry, marine ecology, conservation, nascent tech development—and geographic balance within California. It must submit a substantive report by July 1, 2028 that catalogs scientific gaps (listing methods such as alkalinity enhancement, electrochemical approaches, macroalgae cultivation, nutrient fertilization, artificial upwelling/downwelling, biomass sinking, and mineralization), recommends metrics and scale thresholds for trials, evaluates likely impacts on existing ocean uses, and identifies coordination opportunities with federal, state, and academic partners.The Research Program, to be established on or before August 1, 2028 and administered by the state board in consultation with the council, will award competitive grants and may adopt other financial incentives to projects that include a California partner organization or a resident contractor/staff member.
The program must consult a set of named state agencies (Coastal Commission, Fish and Wildlife, State Lands, State Water Resources Control Board, Ocean Protection Council, etc.) when developing guidelines, and it must make funded projects provide annual public research updates to the council.Operationally, AB1086 requires the state board to share council findings with agencies that would have permitting authority over funded projects, report to the Legislature biennially starting January 1, 2029, and seek partnerships to close knowledge gaps. The bill reserves a funding pathway—$2 million annually for at least seven years upon appropriation—but it also preserves the state board’s existing authority to include marine carbon activities under other carbon capture programs, while explicitly excluding mechanical injection into the seabed from the bill’s definition of marine carbon sequestration.
The Five Things You Need to Know
The state board must appoint a seven-member Marine Carbon Council by August 1, 2027, after a public nomination process and with limits on geographic concentration (no more than three members from the same county).
The council must deliver a report by July 1, 2028 that lists research gaps across specified methods (e.g.
ocean alkalinity enhancement, macroalgae cultivation, mineralization, biomass sinking) and recommends metrics and testing scales.
The Marine Carbon Research Program must be established by August 1, 2028 to award competitive grants and other financial incentives; eligible projects must include at least one California-based partner or a California-resident contractor/staff.
The bill specifies an annual appropriation of $2,000,000 to the state board for no less than seven years to fund the program—but the money is subject to legislative appropriation (i.e.
not an automatic entitlement).
‘Marine carbon dioxide sequestration’ explicitly excludes mechanical injection of CO2 into the seabed, and the state board must share council findings with agencies that would have permitting authority over funded research.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Key definitions and scope
This subsection defines the initiative’s vocabulary: it distinguishes 'marine carbon dioxide removal' (intentional interventions measured on a life-cycle basis) from 'marine carbon dioxide sequestration' (durable ocean storage) and expressly excludes mechanical injection into the seabed from the latter. That exclusion narrows the program’s reach and signals which techniques California intends to study under the initiative.
Creates the Marine Carbon Initiative and sets objectives
The state board must form the Initiative consisting of the Council and Research Program and sets broad objectives: advance in‑ocean testing and field trials, evaluate environmental/ecosystem and socioeconomic impacts to California coastal communities, assess labor and supply chain implications, and produce recommendations for potential commercial deployment. This section frames the Initiative as science-first—research, testing, and assessment—rather than immediate commercialization or permitting.
Council formation, composition, and nomination process
The state board must establish the seven-member Marine Carbon Council with a public nomination process and select members representing industry, universities, federal labs, or nonprofits. The statute lists candidate qualifications—chemistry and biology of removal, marine ecology, and demonstrated commitment to conservation or nascent technology research—and requires geographic balance (no more than three members from one county). The statute also obliges the board to re-open nominations within 60 days of a vacancy, which creates a predictable cadence for replenishing membership.
Council deliverables and engagement authority
By July 1, 2028 the council must identify gaps in scientific understanding across named approaches, propose metrics and testing scales, evaluate impacts to existing ocean uses, recommend partnerships and possible research hubs, and provide expert advice on request. The council may coordinate with federal, state, and local agencies and solicit input from universities and funders. The section empowers the council to be both a gap-identifier and a practical convener to align research efforts.
Marine Carbon Research Program mechanics and agency coordination
The state board must establish the Research Program by August 1, 2028 to competitively award grants and other financial incentives; it must consult the council in program administration. Eligible projects are tethered to California via a partner or resident staff. The state board must consult a named roster of agencies (Coastal Commission, Fish and Wildlife, State Lands, Water Boards, Ocean Protection Council, local air districts) when setting program guidelines, and direct the council to develop standards that balance environmental/community impacts with project needs.
Reporting, funding, and relationship to existing programs
The council must report to the Legislature by January 1, 2029 and biennially thereafter; reports must comply with Government Code Section 9795. The bill specifies an annual allocation of $2 million for at least seven years to the state board 'upon appropriation' to fund the program. Finally, the statute clarifies it does not limit the state board’s authority to include marine carbon projects under the existing Carbon Capture, Removal, Utilization, and Storage Program (Section 39741.1), preserving other deployment pathways.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- California research universities and federal laboratories — gain prioritized access to state funding, formal coordination channels, and the ability to lead controlled field trials and MRV development.
- Marine technology and startup companies — receive a competitive pathway to fund pilot projects, early-stage testing, and help defining commercialization and MRV standards.
- State agencies and planners — obtain consolidated scientific advice and standardized metrics to inform permitting, policy development, and cross-agency decisions about ocean carbon activities.
- Coastal communities (local governments, workforce) — stand to benefit from assessments of socioeconomic and labor implications and from potential research hubs or supply-chain activity that the council evaluates.
Who Bears the Cost
- California Air Resources Board (state board) and partnering state agencies — take on the administrative burden of establishing the council and program, consulting with many agencies, and processing annual project updates and reports.
- California taxpayers and the Legislature — responsible for appropriating the specified funds ($2M/year for seven years) and any additional regulatory or enforcement costs tied to scaled trials.
- Regulatory and permitting agencies (Coastal Commission, State Lands, Water Boards, Fish and Wildlife) — must coordinate with the program, review shared research findings, and potentially manage higher permitting workloads or novel regulatory questions.
- Commercial developers and experimenters — will face MRV and community-impact guidelines set by the council and program, and must partner with California entities, increasing project structuring and compliance costs.
- Fishing, aquaculture, and recreation operators — may experience operational constraints, displacement risk, or monitoring requirements during field tests and pilots that the council recommends.
Key Issues
The Core Tension
The bill’s central dilemma is how to accelerate credible scientific learning about ocean-based carbon removal—so policymakers can judge safety and commercialization—while limiting ecological risk and protecting existing ocean uses; the statute empowers testing and funding but leaves key judgments (testing scale, ethics, MRV stringency, and conflict-of-interest safeguards) to a council and state board that must balance competing economic, scientific, and conservation priorities.
Implementation raises several unresolved operational questions. First, the state board selects council members after a public nomination process, but the statute does not set detailed conflict-of-interest rules or cooling-off periods; the selection authority combined with industry representation could create perceived or actual biases unless the board adopts strict ethics standards.
Second, measurement and verification of marine carbon removal is scientifically and technically challenging—life-cycle accounting, MRV for diffuse ocean processes (e.g., alkalinity changes, biomass sinking), and permanence all remain contested; the bill assigns the council to set standards but leaves open how those standards will interface with carbon markets or regulatory crediting systems.
Third, the bill threads a narrow path on scale: it requires the council to recommend 'limited scales' for testing but gives no statutory boundary for what 'limited' means, placing heavy discretion with the council and state board. That discretion creates implementation risk—too conservative an approach could slow needed learning, while too permissive an approach could increase ecological or user-conflict risks.
Finally, funding is specified ($2 million/year for seven years) yet explicitly 'upon appropriation,' meaning program continuity depends on future budget choices; intermittent funding would disrupt multi-year field trials and MRV development and could bias research toward projects that fit shorter funding cycles.
