A SUSTAINABILITY-WEIGHTED PROCUREMENT PORTFOLIO MODEL (PPM) APPROACH

ABSTRACT

This paper introduces a Sustainability-weighted Procurement Portfolio Model (PPM) applying a category-specific classification system for mapping and prioritizing sustainability exposure across procurement portfolios. The approach informs organizational sustainable procurement strategies, supplier due diligence reviews, and develops a framework for aligning sustainability integration across the procurement portfolio with corporate sustainability targets and strategies. The model is designed to accelerate sustainable public procurement implementation and position public procurement practitioners to strategically guide organizational efforts towards SDG 12.7.
