The PCR Committee of the American Center of Life Cycle Assessment ( is about to kick off an initiative to create a North-American guidance document which will detail the calculations of the additional environmental metrics (i.e., those that are not LCIA impact categories) required by the upcoming revised version of ISO 21930. The goal is to maximize consistency and comparability of these numbers across databases, software, and practitioners so that EPD audiences are provided with meaningful results.
