INTERNATIONAL SURVEY ON CRITICAL REVIEW AND VERIFICATION PRACTICES IN LCA WITH A FOCUS IN THE CONSTRUCTION SECTOR

Use of consistent and representative data is required to obtain reliable LCA studies. To do so, the LCA review is a key part. Yet, at the international level, few guidelines are provided to conduct a critical review. Only, few aspects are mentioned e.g. in ISO 14040 standard. In this paper, findings from an international survey are presented. The survey’s objectives were to get feedbacks from LCA experts on important aspects they checked during their previous reviews with a focus in the European construction sector practices. Results show that most reviewers always check usual aspects of the LCA framework while more specific aspects requiring more background are not. This study can be viewed as a contribution for both general critical review guidelines and improvements of existing review checklist for EPD in the construction sector.
