Successful delivery of the United Nations sustainable development goals and implementation of the Paris Agreement requires technologies that utilize a wide range of minerals in vast quantities. Metal recycling and technological change will contribute to sustaining supply, but mining must continue and grow for the foreseeable future to ensure that such minerals remain available to industry. New links are needed between existing institutional frameworks to oversee responsible sourcing of minerals, trajectories for mineral exploration, environmental practices, and consumer awareness of the effects of consumption. Here we present, through analysis of a comprehensive set of data and demand forecasts, an interdisciplinary perspective on how best to ensure ecologically viable continuity of global mineral supply over the coming decades.
Long-term organisational viability and competitiveness should not be evaluated solely in terms of financial measures. Investors, policy makers and other stakeholders increasingly seek to evaluate performance with respect to sustainability -the environmental, social and economic performance of an organisation. But 10 measuring and improving the sustainability performance of supply chains is challenging. Using one of the world's most critical supply chains, the food supply chain, we introduce and apply a multi-stage procedure to help analytically evaluate supply chains' sustainability performance. The method involves development of sustainability indicators, data collection, data transformation using rescaling and determining of importance ratings using the Analytical Hierarchy Process (AHP). The proposed methodology demonstrates how 15 quantitative statistical data can be combined with expert opinion to construct an overall index of sustainability. Stakeholders can use the index to evaluate and guide sustainability performance of supply chains. Strengths and opportunities, as well as limitations of the methodology are discussed, and sensitivity analysis is performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
