Attributional / book-keeping approach

by: Jannick Hoejrup Schmidt (jannick) 23 September 2013, 7:02:11 AM (GMT +1)

In the 'Draft PCR for open consultation' there are references to "Book-keeping LCA approach (attributional LCA)" and that this is in accordance with principles set in ISO 14025.

Comment: It is problematic to referring to such principles since they are neither defined in the current PCR nor in ISO 14025.

Kind regards,

Dear Jannick,

I will answer this question instead of the PCR Moderator as it does not specifically refer to this PCR, but to the general LCA approach used in the International EPD System.

As you know, the general principles of attributional vs. consequential LCA methodology is well established in the scientific litterature. The mention of attributional approach here is not intended to give a full explanation of the system approach of the International EPD System.

This is instead done in the General Programme Instructions, Annex A, which I refer you to for additional information.

Best regards,

Kristian Jelse,
Secretariat of the International EPD System
