Introducing a new section in the International Journal of Life Cycle Assessment: Critical Review and Life Cycle Assessment Standards

The Editors of the International Journal of Life Cycle Assessment created a new section called “Critical Review and Life Cycle Assessment Standards”. As the subject editor for this new article type, I bring much experience as a critical reviewer, having served in the roles of review panel leader, co-panellist and individual expert. My earliest experience goes back to the Sesimbra workshop on Life Cycle Assessment (LCA) code of practice (SETAC 1993). Furthermore, as member of the German expert group advising the German members of the ISO 14040ff standards, I was responsible for checking the translation (so also responsible for keeping the old German name for LCA: Ökobilanz). I published several papers on the critical review process and the “magical” critical review triangle which includes the Commissioner, Practitioner and Critical review panel (Klöpffer 2012).
The ISO series of LCA-based standards was modified only once (Finkbeiner et al. 2006) into ISO 14040:2006 and ISO 14044:2006. The first standard contains all general statements, such as the structure shown above and how an LCA study should be performed. In ISO, the use of the word “shall” indicates mandatory statements that have to be followed without exception. The only “shall” in ISO 14040:2006 is in the statement that the evaluation shall be performed according to 14044:2006. In this way, studies performed “in the spirit of ISO” cannot be claimed as performed “according to” ISO. In this standard, all strict statements including the critical review are necessary if “comparative assertions” are deduced from the first three items listed above. A statement saying that one of the alternative systems studied is better or at least equal to another system—under environmental aspects—has to be confirmed very strictly in order to be acceptable.
Here comes a key-element of ISO-LCA: the critical review must be performed by experts not involved in the actual study. If no “comparative assertion” is made, a review by one independent expert is sufficient. If, however, comparative assertions are made, a critical review panel of at least three experts including the chair has to check the whole LCA study and write a review report. This can be done after completion of the study, or preferably accompanying, so that improvements suggested by the review panel can be taken into account by the study-performers (practitioners) (Klöpffer 2005, 2012) (ISO TS 2014). The accompanying critical review is in general more expensive due to the need for more frequent panel meetings, etc. The time demand can often be kept comparable to reviews done “a posteriori”. The results of the critical reviews have to be made open to the public, at least upon request.
Depending on confidential product details it may contain, the entire study including the findings of the critical review is often not fully published and made publicly available. This brings us to the core of this editorial which tries to join the critical review process with the standards edited by ISO, and other organisations not mentioned here. Publishing critical reviews (outside the LCA studies to which they belong) has never been popular. As a result, LCA practitioners are often not aware what is expected from them during the review process or if they are invited to review. Here, the new ISO technical specification (TS) 14071 (2014) will certainly be helpful. Experience obtained with this document would be welcome to the whole LCA community. Furthermore, although the ISO standards are the most important ones and have a global reach, there are other life cycle standards which are regionally more restricted or contain only one impact category (mostly “global warming”) or refer to only one product group. Such studies are often called “footprints” and may contain important information with regard to the products and/or impacts they refer to. A comparative assertion about the relative environmental impacts of product systems is not possible in such case. The relevant standards should nevertheless be studied and the limits of the method explored and published in a peer-reviewed journal.
Following the normal route for submissions, papers submitted to the journal via Springer’s website under the new article type “Critical Review and LCA Standards” will be sent automatically to the editor-in-chief and from there to me. To assist in the review process, people with experience in critical review and LCA standards are kindly invited to provide me with their “coordinates” and a short CV for potential submission reviews. Anticipated submissions may cover the announcement of new LCA standards, when that occurs, of course. Problems frequently encountered during the critical review process and how to avoid them could also be a topic.
I look forward to good cooperation within the LCA community for improving the quality of both the use of the standards and the LCA review process.
