Abstract
With the increasing interest in Life Cycle Thinking (LCT) applications for assessing the sustainability of processes, products and services, up-to-date syntheses and evidence-based critical outcomes analysis are required to guide future studies and policymakers. The systematic literature review is probably the most suitable approach for highlighting evidence of effects, impacts, and methodological choices, mapping the current knowledge and gaps in LCT fields, including methods such as Life Cycle Assessment, Life Cycle Costing, Social Life Cycle Assessment and Life Cycle Sustainability Assessment. Although several statements and guidelines for health care and ecology disciplines and one checklist for systematic literature review limited to Life Cycle Assessment (STARR-LCA) exist, it is still missing a framework for conducting systematic literature reviews in LCT field. This paper proposes a "Framework for systematic Literature review to Analyse Vast InformAtion in Life Cycle Thinking studies" (FLAVIA-LCT) to assist and guide researchers in structuring the processes of gathering, synthesising, and reporting outcomes from search strategy development to critical evaluation, considering the essential information to be included in a review manuscript. This framework can be used by anyone planning a literature review on one or more LCT methods.
