The report proposes that comparative LCA studies assess seven additional impact categories alongside existing methods: biodegradability, bioaccumulation, persistence, microplastic formation, biodiversity impact, litter, and biogenic global warming potential. This framework aims to capture environmental characteristics relevant to bio-based materials that existing impact assessment methods do not measure. "Many of the impact categories used today were designed around fossil-based systems, meaning bio-based materials are compared on an uneven playing field." Impact categories and end-of-life treatmentStandard LCA impact assessment methods such as ReCiPe and Environmental Footprint include approximately 16 to 18 midpoint indicators covering areas including climate change, acidification, and ecotoxicity. The Seven Steps to Fairness framework addresses the challenge of identifying impact categories that enable this.
