Environmental Product Declarations, or EPDs, are becoming a cornerstone of transparent sustainability reporting. They provide standardized information about the environmental impact of products across their lifecycle, helping companies, regulators, and customers make more informed decisions. However, the value of a verified environmental product declaration depends heavily on trust, transparency, and a rigorous third-party EPD verification process. This is where third-party verification plays a critical role.
What Is Third-Party Verification?
Third-party verification is the process of having an independent, qualified organization review and validate an EPD. The EPD verification process ensures organizations achieve stronger EPD compliance while improving confidence in sustainability disclosures. This verifier is not involved in the product’s development or the creation of the declaration, ensuring an unbiased assessment.
The verification process typically examines the underlying lifecycle assessment, the data sources used, the methodology applied, and the final EPD document. The goal is to confirm that the EPD complies with relevant standards and accurately represents the product’s environmental impact.
EPD Program Operators and Third-Party Verifiers
Third-party EPD verification is typically managed through accredited program operators and independent verification bodies that oversee compliance with standards such as ISO 14025 and EN 15804. Common organizations involved in third-party verified EPD reviews, EPD certification, verification management, and publication include UL Solutions, Smart EPD, EPD International, EPD Norway, ASTM International, International Organization for Standardization, NSF International, and SGS.
What Is an EPD Program Operator?
An EPD program operator is an organization responsible for managing the framework and publication process for Environmental Product Declarations. Program operators help ensure consistency, transparency, and compliance across published EPDs.
Their responsibilities typically include:
Publishing and maintaining Product Category Rules (PCRs)
- Managing the EPD submission and publication process
- Coordinating independent third-party verification
- Ensuring compliance with standards such as ISO 14025 and EN 15804
- Maintaining public EPD databases and registries
Program operators play a critical role in standardizing how environmental impacts are calculated and reported, making EPDs more credible and comparable across industries and regions.
Building Trust and Credibility
Without verification, an EPD is essentially a self-declared document. Even when created with the best intentions, it may be viewed with skepticism by customers, partners, and regulators. A third-party verified EPD provides stakeholders with greater assurance that environmental claims have been independently validated.
Third-party verification adds a layer of credibility. It signals that the information has been independently reviewed and meets established standards. This is particularly important in industries where environmental claims are closely scrutinized and where greenwashing concerns are high.
For companies, verified EPDs, which are typically valid for five years, can strengthen brand reputation and support more confident communication of sustainability efforts.
Ensuring Consistency and Comparability
One of the main purposes of EPDs is to enable fair comparisons between products. This only works if the data behind those EPDs is consistent and calculated using the same rules.
Third-party verifiers ensure that Product Category Rules are correctly applied and that lifecycle assessments follow recognized standards. This reduces the risk of inconsistencies that could distort comparisons.
As a result, buyers can evaluate products on a more level playing field, and procurement decisions can better reflect true environmental performance.
Industries and Certifications That Require EPDs
Environmental Product Declarations (EPDs) are increasingly required across industries where sustainability reporting, green building compliance, and supply chain transparency are becoming standard expectations. Verified EPDs help manufacturers demonstrate environmental performance, meet procurement requirements, and qualify for sustainability certifications.
Industries Commonly Using EPDs
EPDs are especially important in sectors with high environmental impact or strict sustainability standards, including:
Construction and Building Materials: Concrete, steel, insulation, flooring, glass, roofing, and other construction products frequently require EPDs for green building projects and public procurement.
- Furniture Manufacturing: Commercial and residential furniture companies use EPDs to support sustainability certifications and demonstrate reduced environmental impact.
- Manufacturing and Industrial Products: Machinery, equipment, packaging, chemicals, and engineered products increasingly rely on EPDs for supply chain reporting and customer requirements.
- Consumer Products: Electronics, textiles, and household products are beginning to adopt EPDs as sustainability disclosures become more common.
- Infrastructure and Transportation: Infrastructure projects and transportation-related materials often require verified environmental impact data for compliance and bidding processes.
In sectors such as construction, furniture manufacturing, and industrial products, EPD compliance is increasingly necessary for certification programs, procurement approvals, and green building requirements.
Certifications and Programs That Require or Reward EPDs
Several major sustainability certifications and procurement frameworks either require EPDs or award credits for using products with verified environmental declarations:
LEED (Leadership in Energy and Environmental Design): EPDs contribute toward Materials and Resources credits within LEED-certified building projects.
- BREEAM (Building Research Establishment Environmental Assessment Method): Recognizes products with verified lifecycle environmental data, including EPDs.
- BIFMA LEVEL: Furniture sustainability certification that incorporates lifecycle assessment and environmental transparency requirements where EPDs can support compliance.
- Living Building Challenge (LBC): Encourages transparent material disclosures and lifecycle impact reporting.
- WELL Building Standard: Increasingly values transparent environmental and material health reporting.
- Government Procurement and Public Tenders: Many public agencies and infrastructure projects now require verified EPDs for building materials and manufactured products.
As sustainability regulations continue to expand, EPDs are becoming a competitive requirement rather than a voluntary disclosure. Companies that invest in verified EPDs are better positioned to meet certification requirements, access regulated markets, and strengthen credibility with customers and procurement teams.
Reducing Risk
Unverified environmental claims can expose companies to significant risks. Regulatory scrutiny is increasing, and misleading or inaccurate disclosures can lead to legal consequences, financial penalties, and reputational damage.
Third-party verification helps mitigate these risks by identifying errors, gaps, or non-compliance before the EPD is published. It acts as a quality control mechanism that protects both the company and its stakeholders.
Supporting Market Access
In many markets, verified EPDs are not just a nice-to-have but a requirement. Green building programs, public procurement policies, and industry certifications often mandate third-party verified EPDs.
For example, building rating systems and government tenders may require verified environmental data to qualify. Without verification, companies may be excluded from these opportunities.
This makes the EPD verification process a key enabler of market access, especially in sectors such as construction and manufacturing.
Improving Data Quality Over Time
The verification process is not just about checking compliance. It also helps companies improve their internal processes and data quality.
Feedback from verifiers can highlight areas where data collection can be strengthened, assumptions refined, or methodologies improved. Over time, this leads to more robust lifecycle assessments and more accurate EPDs.
Many companies now use EPD verification software to improve data consistency, reduce manual calculations, and generate audit-ready EPD documentation. This continuous improvement is essential for companies aiming to track and reduce their environmental impact in a meaningful way.
Enabling Better Decision-Making
Reliable data is the foundation of effective sustainability strategies. Verified EPDs provide decision-makers with greater confidence in the information they are using.
Whether it is selecting suppliers, designing products, or reporting emissions, having verified data reduces uncertainty and supports more informed choices. It also allows companies to benchmark performance and identify opportunities for improvement.

EPD Verification: Process, Cost, Timeline & Requirements
Third-party EPD verification is a structured review process that ensures an Environmental Product Declaration is accurate, transparent, and compliant with standards such as ISO 14025 and EN 15804. The process typically involves conducting a life cycle assessment (LCA) established by ISO 14044, preparing the EPD according to the applicable Product Category Rules (PCRs), and submitting the documentation to an independent verifier for review. The verifier evaluates the methodology, data quality, calculations, and compliance before approving the EPD for publication.
The timeline for verification usually ranges from a few weeks to several months depending on product complexity, data availability, and the number of revisions required. Costs can vary based on the scope of the LCA, verifier fees, program operator charges, and internal resource requirements. Companies with well-organized sustainability data and standardized processes can often complete verification faster and at a lower cost.
To achieve a verified EPD, organizations must use high-quality lifecycle data, follow the correct PCR requirements, document assumptions transparently, and complete an independent third-party review. Common challenges include incomplete supplier data, inconsistent methodologies, and time-consuming manual calculations.
