Greenhouse Gas Validation and Verification

The GHG Protocol Corporate Accounting and Reporting Standard provides requirements and guidance for companies and other organizations preparing a GHG emissions inventory. It was designed with the following objectives in mind:

  • To help companies prepare a GHG inventory that represents a true and fair account of their emissions through the use of standardized approaches and principles
  • To simplify and reduce the costs of compiling a GHG inventory
  • To provide business with information that can be used to build an effective strategy to manage and reduce GHG emissions
  • To increase consistency and transparency in GHG accounting and reporting among various companies and GHG programs

The module builds on the experience and knowledge of over 350 leading experts drawn from businesses, NGOs, governments and accounting associations. It has been road-tested by over 30 companies in nine countries.

The GHG Protocol Corporate Standard has been designed to be program or policy neutral. However, it is compatible with most existing GHG programs and their own accounting and reporting requirements. It is important to distinguish between the GHG Protocol Corporate Standard from other GHG programs. This standard focuses only on the accounting and reporting of emissions, but does not require emissions information to be reported to WRI or WBCSD. In addition, while this standard is designed to develop a verifiable inventory, it does not provide a standard for how the verification process should be conducted.

Additionally, ISO is developing new international framework standards to assist non-state actors in meeting climate targets aligned with the Paris Agreement. The ISO-IAF joint side event will highlight the role of these new standards, as well as a harmonized global approach for accreditation, to facilitate the acceptance of verification between economies, build confidence and strengthen governance and transparency in future adaptation activities.
