Best Practices for GHG Assurance on Intertek's Assurance In Action Podcast Network

Greenhouse gas (GHG) assurance is becoming a cornerstone of credible sustainability reporting, as organizations seek to meet regulatory demands and demonstrate accountability in their climate-related disclosures. Third-party GHG verification—an independent assessment of a company’s GHG inventory—plays a critical role in ensuring the accuracy, completeness, and compliance of reported emissions data. By engaging qualified external verifiers, organizations can enhance the transparency of their reporting, build stakeholder trust, and strengthen their positioning in the marketplace.

Successful GHG assurance, however, requires careful preparation and an understanding of key verification standards such as the GHG Protocol and ISO 14064. Common challenges include inconsistent data quality and insufficient allocation of resources—both in terms of time and personnel. Organizations are encouraged to familiarize themselves with the concepts of scope and boundary definitions, as well as to provide clear rationale for any exclusions or deviations in their emissions inventory. Another important consideration is the level of assurance: limited assurance offers moderate confidence with less intensive review, while reasonable assurance involves a more thorough evaluation and higher associated costs. The decision between the two often depends on stakeholder expectations, regulatory requirements, and the intended use of the assurance statement. With proper planning and a collaborative approach, third-party GHG assurance can become a streamlined, valuable part of a company’s sustainability journey.
