Why are EPDs only valid for five years?

EPDs, or Environmental Product Declarations, are only valid for five years primarily to ensure that they remain relevant to modern standards. Over time, scientific understanding and technological advancements can significantly change the metrics and benchmarks used to assess environmental impact. By having a five-year validity period, EPDs encourage manufacturers to review and potentially update their declarations to align with the latest environmental standards, data, and practices. This regular revision helps maintain the credibility and accuracy of the information provided to consumers and other stakeholders, reflecting any changes in best practices or regulations that may have emerged since the EPD was originally issued. Thus, this time frame serves to promote ongoing transparency and accountability in environmental claims associated with the products.
