# Mitigating Reversal Risk: Insurance and Buffer Pool

All Projects must conduct a permanence & reversal risk assessment, as well as create a risk mitigation strategy, aligned with the '[Permanence](https://open-carbon-protocol.gitbook.io/ocp-methodology-requirements/sections/8.-permanence)' section of the relevant methodology. 

Project Developers must monitor for reversals as part of their [monitoring plan](https://open-carbon-protocol.gitbook.io/ocp-methodology-requirements/sections/9.-monitoring) (including the post-crediting monitoring requirements set by the methodology), and are required to notify the program as soon as possible and no later than 5 working days after becoming aware of the reversal event, as per [OCP Terms of Service](https://pilot.ocp.earth/terms-and-conditions). Any single reversal event or cumulative series of reversal events amounting to 5% or more of credited outcomes shall automatically trigger a mitigation response. 

A reversal event will trigger one of the two **OCP Reversal Mitigation Responses**, as set by the methodology:

* **Buffer Pool Contribution and Distribution**: During each credit issuance, a methodology-dependent percentage of credits is contributed to the [OCP Buffer Pool](#ocp-buffer-pool-policy). In a reversal event, current owners of impacted carbon credits will be compensated, as explained in the [OCP Buffer Pool Policy](#compensation-mechanism-and-replenishment-obligations) below.
* **Project Insurance**: During project proposal, project developers must take out an insurance policy with a registered carbon insurance company (e.g. Kita, Oka). In a reversal event, the insurance company will work with the OCP, buyers and other stakeholders to compensate.
  * [We have a partnership with kita.earth](#kita.earth-partnership), who advise on Buffer Pool contributions on a methodology level, as well as offer project insurance for OCP projects. 

The OCP Buffer Pool and Project Insurance **does not compensate for excess issuance / over crediting**, which is documented under '[Credit Cancellation](/ocp-handbook/registry/credit-cancellation.md)'.

## OCP Buffer Pool Policy

### Purpose and Scope

This Buffer Pool Policy establishes the program-level rules governing the design, operation, and governance of the Open Carbon Protocol (OCP) Buffer Pool. The Buffer Pool is intended to ensure the environmental integrity and permanence of issued OCP carbon credits by providing a standardized mechanism to fully compensate for material reversals of credited emissions reductions or removals.

This Policy applies to all OCP-registered projects for which reversal risk is present. Projects can also mitigate against reversal risk through project insurance, if allowed by the methodology.

The OCP Buffer Pool does not compensate for excess issuance / over crediting, which is documented under '[Credit Cancellation](/ocp-handbook/registry/credit-cancellation.md)'.

### Definitions

*For more terms,* [*see the Glossary*](/ocp-handbook/glossary.md)*.*

<table><thead><tr><th width="256.78125">Term</th><th>Definition</th></tr></thead><tbody><tr><td>Reversal<br>also, Reversal Event</td><td>An event where a documented emission reduction or removal within a <strong>project</strong> has been lost or re-emitted after the associated <strong>carbon credit</strong> has been issued. <br><br><em><strong>Avoidable Reversal</strong></em>: A material reversal attributable to negligence, non-compliance, or failure to implement required monitoring or mitigation measures by a <strong>Project Developer</strong>. <br><br><em><strong>Unavoidable Reversal:</strong></em> A material reversal resulting from exogenous factors beyond the reasonable control of the <strong>Project Developer</strong>.</td></tr><tr><td>Material Reversal</td><td>A <strong>reversal</strong> event resulting in a cumulative loss of credited <strong>emissions reductions or removals</strong> exceeding the OCP’s materiality threshold, defined as 5% of the total <strong>carbon credits</strong> previously <strong>issued</strong> to the project.</td></tr><tr><td>Buffer Pool</td><td>A single, OCP-wide pooled reserve of <strong>Carbon Credits</strong> held to compensate for <strong>Material Reversals</strong> of emission reduction/removals from <strong>Projects.</strong></td></tr><tr><td>Cancellation</td><td>The permanent removal of a <strong>carbon credit</strong> from the <strong>OCP Registry</strong> without claiming the associated benefit of the reduction/removal for any voluntary or mandatory target. All cancellation are tracked on the OCP Registry. <br><br>May occur for these reasons: compensating for <strong>reversal events</strong>, compensating for excess <strong>issuance.</strong></td></tr></tbody></table>

### Contribution Requirements

Buffer Pool contributions are set at the Methodology level and approved as part of the Expert Panel approval process.&#x20;

### Monitoring, Detection, and Notification

Project Developers must implement monitoring systems capable of detecting reversal events and potential reversals in accordance with the relevant Methodology and the [OCP Methodology Requirements](https://open-carbon-protocol.gitbook.io/ocp-methodology-requirements/sections/8.-permanence).

Project developers are required to notify the program as soon as possible and no later than 5 working days after becoming aware of the reversal event, as per [OCP Terms of Service](https://pilot.ocp.earth/terms-and-conditions). Notification must include preliminary evidence sufficient to enable the OCP team to assess the magnitude and materiality of the reversal. Confirmed events must have complete disclosure of the data within 45 calendar days of the event.

The OCP will rule on the materiality of the reversal and the corresponding Buffer Pool activities within 90 days of receiving the notification. The OCP Advisory Board will review any Buffer Pool disbursements or cancellations.

### Compensation Mechanism & Replenishment Obligations

All verified material reversals shall be **fully compensated through the cancellation of active credits and/or disbursement of Buffer Pool credits equal to the quantified net emissions loss**.&#x20;

If the Buffer Pool cannot cover the net emissions loss, then either non-OCP credits of similar methodologies or a monetary payout will be granted to the owner of the credits. The OCP reserves the right to use insurance mechanisms to improve the efficiency and efficacy of the OCP Buffer Pool.

In the case of an avoidable reversal, the project developer must replenish the Buffer Pool with carbon credits equal to the amount of the reversal.

Replenishment may be satisfied through:

* future issuances from the same project; or
* alternative arrangements approved by the OCP team.

Failure to replenish will result in enforcement actions, including suspension of issuance, cancellation of issued carbon credits owned by the project developer, or removal of projects.&#x20;

### Transparency and Reporting

The OCP publicly discloses Buffer Pool balance and composition.&#x20;

## kita.earth Partnership

The Open Carbon Protocol is proud to announce our partnership with Kita, a leader in carbon market insurance and risk management. The OCP is designed to bring quality to the market through layers of trust and transparency. Kita will bring a crucial perspective to the Open Carbon Protocol (OCP). 

#### **Buffer Contribution**&#x20;

Kita will advise on buffer pool contributions for OCP methodologies, ensuring more robust risk management. With Kita's guidance, the OCP's buffer pool will be regularly assessed to mitigate risk and ensure its effectiveness and quality.

#### **Project Insurance**

OCP Projects can get project insurance through Kita, limiting the need for buffer pool contributions. We are currently building full technical integration Kita's insurance services will be integrated into the OCP platform via API, providing participants with access to Kita's services within the platform and Kita API access to the underlying data necessary to quickly understand the risk of each project.
