About the model

The principal developer of the USES-LCA model suite which is used in ReCiPe, dr. Mark Huijbregts, is also co-developer of the USEtox consensus model. This model is not used in ReCiPe but is mentioned here because it is currently under review by the UNEP SETAC Life Cycle Initiative with the perspective of a global recommendation as the preferred model for characterization modelling of human and ecotoxic impacts in LCIA. The method was released in 2010 is now included some LCA soft wares (dd January 2011 only SimaPro).

USEtox is an environmental model for characterization of human and ecotoxic impacts in Life Cycle Impact Assessment and for comparative assessment and ranking of chemicals according to their inherent hazard characteristics. USEtox has been developed  by a team of researchers from the Task Force on Toxic Impacts under the UNEP SETAC Life Cycle Initiative.

The mission of the USEtox Team is to improve understanding and management of chemicals in the global environment by further developing, evaluating, applying and disseminating the model USEtox that describes the fate, exposure and effects of chemicals.

USEtox Course

Dr. Mark Huijbregts, who is a lecturer at the Radboud University Nijmegen, and PRé Consultants organise a one day course on USEtox model. This course will give you an understanding of the model concept behind the handling of toxic emissions in life cycle impact assessment. You will also learn how to calculate toxicity factors in practice with the UNEP/SETAC consensus model USEtox.

  • Concepts of toxicity in LCA: Theory behind the life cycle impact assessment methods for toxicity. Explanation of fate, exposure and effect assessment. Similarities and differences between the toxicity models included in various LCIA methodologies, such as CML2000, IMPACT2002+, TRACI, and ReCiPe.
  • Data collection: Which chemical-specific data is required, which databases are available, and how to select the most appropriate input data for the calculation of toxicity factors.  
  • Model application: How to calculate toxicity factors in practice.
  • Interpretation: How (un)certain are the toxicity factors.

The training is suitable for those who want to learn more about the concepts and practical implementation of toxicity in their LCA studies.
