Reliability audits for sustainable aviation fuel (SAF) programs

To advance their low-carbon strategies and unlock commercial value, airlines are increasingly launching SAF programs that enable corporate customers, cargo partners and other stakeholders to claim the associated environmental benefits. With these programs, airlines can monetize the use of SAF, meet customers' Scope 3 emissions reporting needs and align with industry climate goals. Verified SAF programs not only increase transparency and credibility, but also help airlines recoup a portion of SAF costs by transferring environmental benefits to their customers. With growing volumes of SAF transactions and changing regulations, airlines face greater pressure to ensure transparency and avoid problems such as double counting or inaccurate claims. Normec Verifavia provides independent SAF program audits to validate these claims and provide assurance in line with leading frameworks. We have audited more than 44 million liters of SAF certificate transactions, ensuring the credibility and robustness of the airline's SAF program.

Platform Assurance Audits.

Airlines often participate in multiple reporting systems, each with different scopes, methodologies, emission factors and additional mandatory programs such as ReFuelEU Aviation and Non-CO₂ climate impact monitoring. To navigate this technical complexity, many operators now rely on automated platforms and digital tools to streamline sustainability reporting and compliance. With the emergence of such tools used for emissions tracking, regulatory reporting and book and claims systems, ensuring their accuracy and alignment with evolving environmental regulations has become critical. Over the past two years, Normec Verifavia's independent platform audits have played an important role in verifying that these digital solutions meet regulatory requirements and industry standards.

Airport Carbon Accreditation (ACA).

Airport Carbon Accreditation (ACA) is the globally recognized certification for airport carbon management and offers seven levels (1, 2, 3, 3+, 4, 4+ and 5) for measuring and reducing carbon emissions. Approved by ACI Europe and Environmental Minds (the ACA program administrator) since 2014, Normec Verifavia verifiers verify more than 400 carbon footprints at 150+ airports worldwide, approximately 28% of all accredited airports. Our multilingual auditors ensure compliance with ISO 14065:2020, ISO 14064-3:2019, ISO/IEC 17029:2019, IAF MD 6:2023, and the ACA Verifier Manual, providing reliable, independent assurance at every ACA level.

Greenhouse gas and carbon footprint verification.

Organizations are becoming more responsible and proactive in promoting sustainability initiatives to meet the increasing expectations of stakeholders such as business partners, investors, analysts, the media and customers. With regulations such as the CSRD and frameworks such as the GHG Protocol mandating sustainability reporting, companies must ensure that their carbon data is accurate and audit-ready. Carbon footprint verification also provides a comprehensive picture of a company's environmental impact by including Life Cycle Assessment (LCA) for all products. In recent years, Normec Verifavia has supported companies in verifying Scope 1, 2 and 3 emissions along with related energy consumption data. Our independent verification services help quantify the greenhouse gas emissions resulting from a company's operations, thereby enabling the company to demonstrate its commitment to reducing the effects of climate change.
