The flowchart presents a structured research framework that progresses sequentially through objectives and is arranged vertically with downward arrow connections among them. The first box is titled “Research Objectives” and lists three items: “Quantify the relative weight of concern for environmental sustainability versus concern for human health management”, “Determining the S D G alignment using a novel weighting of the certification criteria, highlighting priorities and gaps”, and “Create and use the Integration Index to assess the harmony between environmental and health factors and introduce a novel scale to measure sustainability performance. A downward arrow leads to the second box titled “Phase 1: Data Collection and S D G Mapping”, which includes the factors “1.1, Selection of certification systems and versions”, “1.2, Identification of data sources”, and “1.3, S D G Mapping Procedure and Rules”. Another downward arrow connects to the third box titled “Phase 2: Quantitative Weighting and Index Development”, which contains factors “2.1, Normalization and S DG Contribution Calculation”, “2.2, Development of the Integration Index: Coverage Balance, Synergy score”, and “2.3, Sensitivity analysis”. A final downward arrow leads to the fourth box titled “Phase 3: Gap and Synergy Analysis,” which includes factors “3.1, Gap analysis”, “3.2, Conflict identification”, and “3.3, strategic recommendation formulation”.Research design and methodology flowchart.
