Key indicators to assess construction supply chains from an environmental perspective: taxonomy and critical insights

Abstract

The construction industry heavily impacts the environment, with issues like resource use, emissions, and waste. Quantifying these impacts with suitable indicators is vital for sustainable development. Yet, selecting these indicators for construction supply chains is complex due to environmental system intricacies. Our study aims to address this by reviewing existing indicators and proposing a taxonomy. Through systematic literature review following PRISMA guidelines, indicators were extracted and a taxonomy with three categories (i.e., indicator type, assessment level, area) was developed. This research reveals a variety of indicator sets, aiding in evidence-based sustainability assessments for the construction sector.
