The USEtox Team is a team of international researchers (see figure) established under the auspices of UNEP/SETAC Life Cycle Initiative.

The aim of the USEtox Team is to provide a scientific and technical rationale to the comparative assessment of chemicals based on their impacts on human health and on ecosystems (as applied in life cycle assessment, chemical substitution, comparative risk screening and more). The USEtox Team aims at:
- creating and maintaining a model for calculating characterization factors for human toxicity and ecotoxicity impacts,
- increasing the availability and quality of characterization factors for use in life cycle assessment and other comparative assessment contexts for all kinds of chemicals,
- disseminating the USEtox model and characterization factors through the organization of workshops, trainings, and demonstration projects (see Events; tailored training for companies & other institutions is also offered here),
- contributing to create international consensus on the principles for comparative assessment of chemicals.
The USEtox Team is not-for-profit.
