Input-output (I-O) analysis is a quantitative methodology for modeling systems consisting of interdependent components. It provides an elegant mathematical framework for describing the interactions of the system components using a system of linear equations. Although originally developed for economic modeling purposes, the I-O framework has been extended to various systems that are characterized by high levels of internal connectivity. Its ability to capture the ripple effects that cascade through the system makes it a well-suited tool for analyzing interactions among man-made systems with the environment, via withdrawal of natural resources and generation of wastes and pollutants. It has thus been used to address contemporary sustainability issues such as that of climate change mitigation and adaptation through industrial systems optimization. This article provides a brief overview of I-O analysis as it applies to the sustainability analysis of such systems. An illustrative example is presented to demonstrate the computational principle of I-O models. © 2017 Elsevier Inc. All rights reserved.
