Sustainability Assessment of Ores and Metals

Sammanfattning: The procurement of ores and metals necessitates consideration of the sustainability of both the productand of the producer. Current trends in procurement practices move toward assuring the lowestenvironmental, social and economic impacts feasible. In order to ensure a high level of sustainability inthe raw materials acquired, the practices and methods of the producers must be evaluated. To this enddifferent assessment models may be used. This report aims to, through an investigation ofcontemporary assessment models; develop an assessment model which facilitates the sustainableprocurement of ores and metals with a reduced need for compliance from the assessed parties. Theevaluation is carried out based on the triple bottom line (TBL) definition of sustainability and considersthe practices and needs of the ores and metals industry. A number of desirable traits were found in themodels evaluated. A design for a novel assessment model is proposed for scoring ore and metalproducers. The proposed model features recommendations for weighing methods and specifications forimpact indicators, measurement methods, and grading methods.
