Why is the validity of the EPDs established in 5 years, when all the other PCRs establishes it in 3 year max, and the GPI says that "the validity shall not exceed three years" ??

Dear Gorka,

EN 15804 mandates a five year validity of EPDs for construction products, why PCRs that claim compliance with this standard shall have this as the EPD validity period. The General Programme Instrucitions version 2.5 has improved the instructions given on this topic and others when EN 15804 diverges from the general guidance.

Best regards,
Kristian Jelse
