Characterization Factors

by: Mihaela Dimonu (mihaela.dimonu) 05 December 2016, 11:07:47 AM (GMT +1)

Dear Madam/Sir,
I am writing for asking a clarification regarding the characterization models and factors to be used. The PCR states that the characterization factors outlined in EN 15804 (CML baseline) shall be used or improves ones if these factors are updated in a forthcoming revision of EN 15804.
The point is that the last edition of EN 15804 indicates CML 4.1 version 2014, subsequently updated. Can be accepted LCIA results calculated with a new updated method that the one indicated in the reference PCR?

Thank you in advance.

Best regards,
Mihaela Dimonu

Dear Mihaela,

In my understanding, EN 15804+A1 mandates the use of the characterisation factors use in Annex A of the standard, i.e. version 4.1 of CML.

Best regards,
Kristian Jelse, Secretariat
