An EPD is valid from completion of the last step of the EPD process (Registration & publication) until a final validity date, which is declared in the EPD.
The EPD validity is normally five years. An expired EPD can still be published to give environmental information for products still in use, but shall not been used in marketing.
A published EPD shall be updated during its validity if there are errors in the declared information or if changes in technology or other circumstances have led to:
- an increase of 10% or more in the aggregated results over included life-cycle stages for any of the declared environmental performance indicators , or
- substantial changes to the declared product information (e.g., change of manufacturing site, change of lifespan, products added in EPD of multiple products), content declaration (e.g., new material/substance, changed composition), or additional environmental, social, or economic information.
The above rules on when to update a GPI are from GPI 5.0.0. Older versions of the GPI may have slightly different rules.
