Modelling future materials use and its economic drivers

This chapter presents the rationale and policy background for this material resources outlook, including the methodology behind the projections of materials use to 2060. Specifically, it outlines the main economic model and explains how materials have been linked to the economic flows in the model. As the projections presented in this report reflect a baseline scenario, this chapter also explains the nature of such scenarios and the policy assumptions that are included in this particular scenario. The chapter concludes with a roadmap of the report to guide the reader through the various chapters and steps of the analysis.
