# Approved Validation and Verification bodies (VVBs)

Validation and verification provides an independent and transparent process for ensuring the integrity and credibility of greenhouse gas emission reductions and removals

### Overview

Validation and Verification Bodies (VVBs) are independent third-party organizations responsible for assessing climate projects and greenhouse gas (GHG) emission mitigation outcomes under the International Carbon Registry (ICR) program.

VVBs conduct **validation and verification activities** in accordance with applicable ICR requirements and relevant ISO standards. Their role is critical to ensuring the credibility, transparency, and environmental integrity of climate projects registered under the ICR program.

Within the ICR program, VVBs assess project documentation, monitoring reports, and GHG statements and provide independent validation and verification reports that support project registration and the issuance of carbon credits.

Validation and verification activities are conducted according to internationally recognized standards, including **ISO 14064-3**, which define requirements for validation, and verification of GHG emission reductions and removals in addition to **ICR validation and verification specifications**.

#### Eligibility

An **approved VVB** under the ICR Program is a validation and verification body that:

* is approved by ICR;
* holds valid **ISO 14065** accreditation issued by an accreditation body that is a member of the **International Accreditation Forum (IAF)** or **Global Accreditation Cooperation Incorporated (GACI)**, covering the applicable validation or verification activity and sectoral scope; and
* has an active **VVB agreement** with ICR.

See [Accreditation](/documentation/icr-program/validation-and-verification/accreditation.md) for details and [Application for VVBs](/documentation/icr-program/validation-and-verification/approved-validation-and-verification-bodies-vvbs/application-for-vvbs.md) to apply.
