This chapter is part of a book which provides an introduction to input-output analysis for sustainability practitioners.

It is designed for those with knowledge about the sustainability dilemma we face, but who are unsure about the how of measuring our impacts, tracking our progress and informing the decisions for a sustainable future.

Input-output analysis placed in a transdisciplinary setting is a method that captures the complexities and interdependencies of our social, economic and environmental support systems.

Examples of the use of input-output analysis in life-cycle assessment, triple bottom line accounting and carbon and ecological footprints are provided along with an introduction to a range of software tools. In academic circles research has been gathering pace on these methods and issues over the last years.
