Independent Sustainability Audits: Need of the hour 

Introduction 

Normec Verifavia is a globally trusted independent verifier, serving both regulatory and voluntary emissions schemes in the aviation sector. In the first quarter of 2025 alone, Normec Verifavia verified compliance of over 200 airlines under EU/CH ETS, UK ETS, CORSIA, and ReFuelEU. Since the launch of our airport services, we have also verified a total of over 150 airports under the Airport Carbon Accreditation (ACA) programme. Responding to increasing market demand, we have broadened our services to cover voluntary assurance areas such as SAF Program Assurance Audits, GHG and Carbon Footprint Verification, KPI verification, and Platform Verification, supporting our clients in achieving transparency, credibility, and sustainability excellence. 

Sustainable Aviation Fuel (SAF) Program Assurance Audits 

To advance their decarbonization strategies and unlock commercial value, airlines are increasingly launching SAF programs that enable corporate clients, freight partners, and other stakeholders to claim associated environmental benefits. These programs allow operators to monetize SAF use, meet the Scope 3 emissions reporting needs of customers, and align with industry climate targets. Verified SAF programs not only enhance transparency and credibility but also help airlines recover a portion of SAF costs by transferring environmental credits to their customers. With growing volumes of SAF transactions and evolving regulations, airlines face greater pressure to ensure transparency and prevent issues like double counting or inaccurate claims. Normec Verifavia offers independent SAF Program Assurance Audits to validate these claims and provide assurance in line with leading frameworks. We have audited over 44 million litres of SAF certificate transactions, ensuring the airline’s credibility and robustness of its SAF program.  

Platform Assurance Audits 

Airlines often participate in multiple reporting schemes, each with different Monitoring, Reporting and Verification (MRV) scopes, methodologies, emissions factors, and additional mandatory programs such as ReFuelEU Aviation and Non-CO₂ climate impact monitoring. To navigate these technical complexities, many operators now rely on automated platforms and digital tools to streamline sustainability reporting and compliance. With the rise of such tools used for emissions tracking, regulatory reporting, and Book and Claim systems, ensuring their accuracy and alignment with evolving environmental regulations has become critical. Over the last two years, Normec Verifavia’s independent platform assurance audits have played a key role in verifying that these digital solutions meet regulatory requirements and industry standards. 

Airport Carbon Accreditation (ACA) 

Airport Carbon Accreditation (ACA) is the globally recognised certification for airport carbon management, offering seven levels (1, 2, 3, 3+, 4, 4+, and 5) to measure and reduce CO₂ emissions.  Verifiers from Normec Verifavia are approved by ACI Europe and Environmental Minds (the ACA programme administrator) since 2014, verifying over 400 carbon footprints at 150+ airports worldwide, about 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, delivering trusted, independent assurance at every ACA level. 

GHG & Carbon Footprint Verification 

Organizations are taking greater responsibility and becoming more proactive in advancing sustainability initiatives to meet growing expectations from stakeholders such as business partners, investors, analysts, the media, and customers. With regulations like the CSRD and frameworks such as the GHG Protocol making sustainability reporting mandatory, companies must ensure their carbon data is accurate and audit-ready. Carbon footprint verification also offers a comprehensive view of a company’s environmental impact by incorporating Life Cycle Assessment (LCA) across its products. Over the past few years, Normec Verifavia has supported companies in verifying Scope 1, 2, and 3 emissions, along with related energy use data. Our independent verification services help quantify the greenhouse gas emissions that result from a company’s operations and thereby enable the company to demonstrate its commitment to mitigating the effects of climate change. 

Environmental KPI Verification 

Normec Verifavia, in compliance with the NF EN ISO/IEC 17029:2019 standard, offers independent verification of environmental KPIs to ensure the accuracy, transparency, and global alignment of your data. Our independent verification covers key indicators such as fuel efficiency, carbon emissions, water usage, and waste management, providing assurance that your reported data is accurate, credible, and aligned with applicable standards. 

 

Conclusion

As sustainability standards continue to evolve, Normec Verifavia remains committed to supporting the aviation sector with trusted, independent verification services. From SAF program assurance audits to platform audits, and carbon footprint, our expertise helps clients to meet regulatory obligations, improve data transparency, and enhance environmental performance. With a growing demand for sustainable reporting, it becomes essential for companies and airlines to track the record of their carbon footprint and engage with a third-party verifier.
