Previous environmental studies indicate several barriers to circular economy and material efficiency including a lack of detailed methodologies for manufacturing improvement in terms of environmental and operational performances to measure, monitor and evaluate material consumption and waste generation. A lean and green tool, the green performance map (GPM), is an appropriate tool for different environmental initiatives including training, improvement, reporting and development. Through literature review and multiple case study methodology, this chapter presents the current application of GPM in industry and its usage to regularly measure and monitor material efficiency measurements on different levels and to remove barriers to improved material efficiency.
