Read moreAn EPD is obtained in six steps: PCR selection, data collection, LCA model, EPD document, independent verification and publication by a programme operator. Typically 6–14 weeks; the cost has four components.
Read moreDefaults are easy but expensive: by design they represent poor performance. What it costs to move to actual data, and what it returns.
Read moreThe GHG Protocol gives method; ISO 14064-1 builds a verifiable management system. How they differ, the category structure and verification requirements.
Read moreThe standard that explains why an EPD needs a program operator, why it cannot exist without a PCR, and what separates Type I, II and III.
Read moreCompare with a competing product and disclose it publicly, and ISO 14044 requires a review panel. The reasoning behind the rule and its practical consequences.
Read moreComparing feature lists misleads. What actually decides it is database access, verifiability and fit with your workflow.
Read moreThe calculation behind an EPD is an LCA, but not a free one: the PCR dictates what you calculate and how. The flow from rule set to result table.
