The critical review provides quality assurance to life cycle assessments
(LCAs) by providing an unbiased view on the subject, identifying potentials
for improvement and hence contributing towards more scientifically robust
and defensible results.
The DEKRA critical review process is designed to achieve these goals by
working in close collaboration with LCA practitioners. In accordance with
the specific standards used to carry out LCAs, DEKRA developed practical
guidelines which provide the respective methodological framework for
critical reviews. Experience has shown that this critical review process
enhances the quality and credibility of the LCA and additionally contributes
towards knowledge building on the side of the LCA practitioner and
commissioner of the study while not exceeding target costs.
