A life cycle-based certification scheme has been developed for stepwise certification of footprint data to be communicated by blockchain through metal value chains. The need for metals and minerals grows with new technology and with transition to new forms of energy. At the same time the demand increases from manufacturers and consumers who want to know the sustainability performance of materials of the products they buy. Mining industry’s negative impact on the environment and the local communities worries many. The Swedish mining industry therefore wants to disclose their sustainability performance throughout their value chain. Svemin – the Swedish Association of Mines, Mineral and Metal Producers, initiated the project TraceMet – Traceability for sustainable metals and minerals, a project that involves actors from the entire value chain, from mining to end user. To build on stable ground and to facilitate international adoption the certification scheme is based on the international standard for environmental product declarations and on the European standard for product category rules for construction products and services. In addition, for data input, the certification scheme relies on any existing third-party data verification schemes, such as financial or greenhouse gas reporting. The overall certification scheme is established by applying the international standard ISO/IEC 17029:2019 for conformity assessment. A certification scheme based on established international standards facilitates not acceptance and adoption, but also significantly accelerates the establishment of available competence for implementation. The pilot system has been verified and tested, including collection of local data, stepwise certifiable EPD:s, and blockchain data consistency. Next steps are to widen the pilot cases, to speed up and increase the efficiency of the production and certification of data, and to include more types of sustainability impact category footprints.
