For considering consumer exposure, a near-field/far-field modeling framework was developed and is available (Fantke et al. 2016, Fantke et al. 2021) that was recommended in the global UNEP-SETAC GLAM effort to be implemented in USEtox as from version 3. This framework has already been applied in various case studies, is fully mass balance based and aligned with USEtox, which allows to combine impacts from product constituents with impacts from emissions along product life cycles.
