Integrity and AccountabilityCARBON INSURANCE INSTRUMENTS
Lever last updated: 10 September 2026
Insurance policies that pay out if a removal project suffers a defined loss, such as reversal.
Cost
Low to High
An insurer pays for staff, project risk assessments and compensation when an insured loss occurs. Like home insurance, customers pay premiums, meaning regular fees, which help finance payments to those who suffer covered losses. For CDR, a payment might fund replacement credits after stored carbon is released. As indicative planning ranges, a limited programme operated by an existing insurer could require EUR 1 million to EUR 10 million annually; a large programme covering many valuable projects could require EUR 100 million to EUR 1 billion, depending on claims. The insurer may also pay another insurer to absorb part of its risk, called reinsurance. For comparison, Flood Re, the UK scheme that reimburses insurers for household flood losses, recorded GBP 151.3 million in claims and related service costs in 2024/25. Money held in reserve for an unusually bad year is additional funding needed, rather than an amount spent every year.
Complexity
Medium to Very high
An existing insurer needs risk models, policy terms and claims procedures. A new public facility adds legislation and capital arrangements; a facility requiring a new international mandate adds treaty-level coordination.
Timeline
Short to Long
An existing insurer can make limited cover available in one to two years. A new domestic facility may need two to five years; creating an international mandate can take five to ten years before policies take effect.

Policy Architecture & Coordination
Overview
An authorised insurer can offer a removal buyer or developer a contract promising a remedy if a defined loss occurs. The buyer or developer pays a premium, the price of the protection, and becomes the policyholder. The insurer must have resources to pay covered claims; a broker or specialist intermediary may design and arrange the policy without carrying that obligation itself. Cover can address failure to deliver contracted credits, reversal of stored carbon, invalidation of credits or specified damage to removal infrastructure. A government or international public institution can also establish a funded insurance facility where its legal mandate allows. The lever transfers an agreed risk to an institution that can spread losses across a portfolio. Requiring a project to obtain cover is the separate financial-assurance lever; a state promise to cover exceptional losses behind insurers sits under Liability Caps and State Reinsurance Backstops.
Key Considerations
Each policy should name the policyholder, the institution that must pay, the beneficiary receiving payment, and the event that triggers a claim. The maximum payment, duration, exclusions and deductible, the loss the policyholder bears itself, determine how much risk actually moves. A developer’s policy does not automatically protect its buyer unless the contract gives the buyer rights. The insurer may buy reinsurance, meaning insurance for part of its own exposure, but must remain clear about its obligation to the policyholder. Cover can pay money, replace eligible credits or fund repairs, depending on its terms. A cash payment can compensate a financial loss without delivering a missing removal. Replacement quality, timing and treatment in the registry therefore need express terms.
Opportunities
A buyer that would otherwise lose an advance payment if a project under-delivers can purchase a defined remedy, making an early or longer contract easier to negotiate. A developer can similarly insure specified repair or liability costs that lenders are unwilling to leave wholly with the project company. The insurer combines premiums and capital across projects, so one policyholder does not have to fund every covered worst-case loss alone. Reinsurance can spread part of that exposure further. Project screening and better terms for effective prevention can also encourage risk reduction. The practical benefit depends on whether buyers and lenders accept the policy’s limits, duration and claims process; issuing a policy does not by itself establish cheaper finance.
Risks
Premiums add costs, and exclusions can leave buyers with less protection than they expected. A common drought or technical problem can cause many claims at once; rising credit prices may also make promised replacements more expensive. Disputes or insurer failure can delay the remedy. Insurance can weaken incentives to prevent losses if operators expect someone else to pay, while cash compensation alone does not replace a failed removal. Mandatory cover that is unavailable or unaffordable can exclude smaller projects without providing better protection.
Monitoring and Evaluation
Risk-bearing insurers and any authorities or credit programmes accepting their policies should examine the volume and duration of protection, exclusions, claims, settlement times and the quality and timing of replacement credits. They should check whether policies still respond after a developer fails and whether lenders or buyers change contract terms because cover exists. Anonymised incident and claims records can inform revised prices and conditions. Unpaid claims, recurrent exclusions or poor replacement performance should prompt a review of whether the product remains suitable for the programme accepting it.
Stakeholder Engagement
Developers, buyers and lenders should identify the losses that prevent them from committing money. Insurers assess and price those risks, reinsurers decide which share they will absorb, and brokers and specialist intermediaries arrange the cover without necessarily paying claims themselves. Public sponsors must give any public insurer a defined mandate, resources and independent risk oversight. Carbon-standard owners determine whether a policy can satisfy a crediting obligation. Insurance supervisors check whether the insurer has adequate resources and is authorised to provide the cover, while independent technical experts test monitoring and replacement assumptions.
Governance Levels
Authorised private insurers can issue policies, often through specialist intermediaries. National and state governments can establish public insurers under appropriate legislation. International institutions can provide insurance within their mandates, as the World Bank Group’s political-risk insurance illustrates. A supranational body such as the EU could establish a funded facility with the necessary legal and budgetary authority; regulating insurers alone does not pull this lever.
Implementation Strategies
The proposed insurer should identify a specific loss that prevents buyers, developers or lenders from contracting. It should define the policyholder, beneficiary and institution responsible for paying, then distinguish credit-delivery, reversal, invalidation and physical-damage cover. Public sponsors also need explicit authority and funding for any public insurer.
Insurers and intermediaries should test the policy against real project contracts, including insolvency and a disputed claim. Terms should explain who can claim, how losses are assessed, what is paid and when, and whether the remedy actually replaces removals. Programme owners should assess that performance before recognising the policy as adequate protection.
Programme owners should compare insurance terms with reserve and financial-assurance obligations before accepting cover. Each instrument should pay for a specified loss or share of loss, with an agreed order of payment to prevent gaps and duplicate charges.
Insurers should share anonymised records of incidents and claims where commercial and legal constraints allow. They should use these records to revisit prices and exclusions, test simultaneous project failures and arrange enough reinsurance before enlarging the insured portfolio.
Case Studies

Kita carbon purchase protection
Kita is a specialist intermediary that develops and arranges carbon insurance. In January 2023, insurer Chaucer announced that it would lead the underwriting capacity for Kita’s protection against carbon projects delivering fewer credits than expected, with other insurers sharing the risk. A buyer purchasing credits in advance could therefore buy a separate insurance remedy for a defined shortfall. Kita arranged the product, while the named underwriting institutions supplied the financial promise. That division makes the operative actor clear and addresses the risk that discourages an early purchase before credits exist. The announcement demonstrates an available insurance arrangement, not measured reductions in financing costs. Under-delivery cover must not be assumed to include every later reversal, invalidation or environmental claim.

CarbonPool and Verra's durability pilot
Verra, a carbon-crediting programme operator, launched a durability pilot in December 2025 allowing eligible projects to use approved insurance instead of setting aside buffer credits. In July 2026 it approved policies from CarbonPool and Kita. CarbonPool’s product is backed through Oka Syndicate 1922 in the Lloyd’s insurance market; CarbonPool arranges the cover rather than acting as the insurer itself. An admitted project can pay a premium and sell credits it would otherwise withhold, while covered reversal risk passes to the insurer. The programme links affected credit status to the replacement process. The mechanism shows how insurance can substitute for one specified reserve obligation, subject to programme approval and policy terms. Approval does not demonstrate claims already paid or adequate protection against every possible loss.

Marsh insurance for shared CO₂ transport and storage
Marsh is an insurance broker that arranges cover with risk-bearing insurers. Its carbon-management products include storage-leakage cover backed by Canopius and Hiscox, and a product with HDI Global for losses caused by CO₂ that fails agreed quality specifications. Contaminated CO₂ from one participant can disrupt a shared network and leave other users with financial losses and remediation costs. The latter policy addresses specified legal defence, clean-up and other participants’ losses, making that contractual exposure insurable. These are offered products for carbon transport and storage, not proof that a particular CDR claim has been paid. Their direct lesson is to match insurance to the point where one company’s failure creates obligations across a shared infrastructure chain.

Allianz construction cover for Stratos and Northern Lights
Allianz Commercial, the business-insurance arm of Allianz, reported in August 2023 that it was co-leading construction insurance for Stratos, a direct-air-capture project in Texas. It also described leading construction cover for the receiving terminal and offshore storage facilities of Northern Lights in Norway. Insurance allows project owners to transfer specified construction losses to insurers while contractors build the assets. The named engagements supply project-level evidence that established insurers can cover large carbon-management infrastructure, including a CDR facility. They do not establish that the policies insure every future tonne removed, long-term reversal or credit invalidation. The distinction matters because protection for an asset during construction and protection for a removal buyer’s climate claim are different products.
