International Molybdenum Association (IMOA) life cycle assessment program and perspectives on the LCA harmonization effort

摘要

In 2001, the International Molybdenum Association (IMOA) initiated their life cycle assessment (LCA) program performing cradle-to-gate life cycle inventories (LCIs) of three molybdenum metallurgical products, followed by LCIs of eight molybdenum chemicals and an update to the metallurgical LCIs. From 2012 to 2014, IMOA participated in a multi-metal industry initiative to harmonize the methodological approach to metal-related LCAs. This paper describes some of IMOA's conclusions formed from its program and, coupled with its involvement in the multi-metal initiative, provides some lessons learned.
