This book highlights various methods for quantifying sustainability indicators using different indices. To date, numerous sustainability indicators encompassing either all three pillars (economic, environmental and social) or individual or joint indicators (e.g. environmental and social) have been developed and quantified. In addition to commonly developed indicators, which can be utilized for any industrial sector, sector-specific sustainability indicators are frequently used. Behind each indicator developed, there is a unique scientific model, method or assessment technique. This book explores and elaborates on such indicators, and on associated details such as the concept, development methodology, assessment technique, and applications of each indicator.
