For an Environmental Product Declaration to be valid it has to be verified by a third party, to ensure its credibility and correctness.
Pre-verification in the context of an Environmental Product Declaration (EPD) tool entails a thorough testing process to ensure the tool’s data sources, methodologies, and the results it generates comply with current standards. This way the EPD software is confirmed to have output that conforms with all norms and standards EPDs fall under.
There are two ways of verifying EPD software:
- LCA Tool (pre-verification): The input stays more flexible but the output still requires a shortened verification step. This is well-suited, if software systems for data input are rather heterogeneous (so there is no unified data input format), products differ strongly from each other, or rather small amounts of EPDs are needed.
- EPD Tool (full verification): After an initial setup, process steps, material categories and background database matches are fixed. The data input process needs to be repeatable. Then the software can be fully verified outputting verified EPDs without delay.
