Creating an Environmental Product Declaration (EPD) is becoming a vital step for construction products manufacturing companies wishing to remain competitive in sustainability aware world. An EPD provides a comprehensive overview of a product’s environmental impact over its life cycle, but to ensure credibility and accuracy, it must undergo a rigorous verification process. Here’s a step-by-step guide to navigating this essential phase:

Step 1: Understand the Requirements

Before initiating the verification process, familiarize yourself with the specific standards and guidelines applicable to your product category. For construction products in Europe, the EN15804+A2 standard serves as the foundational guideline, while in USA and Canada ISO 21930 does the same.This standard outlines the core rules and life cycle assessment (LCA)procedures necessary for creating an EPD. Additionally, consulting the ProductCategory Rules (PCR) relevant to your product will help ensure compliance with specific reporting criteria.

Step 2: Conduct a Thorough Life Cycle Assessment

A comprehensive life-cycle assesment (LCA) is the backbone of any EPD. This assessment analyzes the environmental impacts associated with all stages of a product's life - from raw material extraction and manufacturing to use and end-of-life disposal. Ensure that your LCA adheres to the methodologies prescribed by EN15804+A2 and other relevant international standards, such as ISO 21930. This step is crucial as it forms the basis of the data that will be presented in your EPD.

Step 3: Compile EPD Documentation

With the LCA completed, document the findings in an EPD format. This document should be clear, detailed, and transparent, including the methodology, data sources, and assumptions used in your LCA. Ensure that it meets the requirements set out by the relevant PCR and aligns with the guidelines provided by EPD program operators.

Step 4: Choose an Accredited Program Operator

Selecting a credible program operator for EPD verification is essential. Program operators are responsible for overseeing the verification process and ensuring that your EPD complies with industry standards. Look for operators who are accredited and have expertise in your specific product category. Their role is to conduct an impartial review of your EPD, examining its content and methodological integrity.

Step 5: Verification Review Process

The verification process involves a detailed examination of your EPD to ensure it accurately represents your product’s environmental impacts. During this stage, the program operator will review your LCA data, check compliance with applicable standards, and may request additional information or clarifications. Be prepared for an interactive process, where the verifier may suggest adjustments or request further data to support your EPD’s findings.

Step 6: Address Feedback and Revise

Based on the feedback from your verifier, make any necessary revisions to your EPD documentation. This might involve refining data points, clarifying interpretations, or adjusting the presentation of your findings to enhance clarity and transparency. Ensure that all adjustments are meticulously documented, as they form an essential part of the verification record.

Step 7: Final Approval and EPD Publication

Once the verifier is satisfied that your EPD meets all necessary criteria and standards, they will give it their final approval. With this approval, your EPD is ready to be published and shared with stakeholders.Make sure to publish your EPD through appropriate channels, enabling easy access for clients, policy makers, and other interested parties looking to assess the environmental performance of your product.

Conclusion

Navigating the EPD verification process is a critical step in demonstrating your product’s environmental credentials. By following this structured approach, your company can ensure that its EPDs are accurate, reliable, and reflect a genuine commitment to sustainability. Moreover, a verified EPD not only enhances your product’s market credibility but also aligns your business with growing environmental demands, paving the way for sustainable success.
