There is agreement in the Life Cycle Assessment (LCA) community that current resource assessment methodologies have limitations when it comes to informing materials selection. Currently, the European Union’s Product/Organisational Environmental Footprint method (PEF/OEF) contains an interim solution, while calling for further method development to provide a long-term solution. As a result, the International Council on Mining and Metals (ICMM) has been working with the Technical University of Denmark (DTU) and other leading Life Cycle Impact Assessment experts to develop a new method for assessing resource use in LCA.
