TARGETS is a simulation model designed to help explore the future of the world innovatively and to search for adequate operationalization of the  concept of sustainable development.  It incorporates a unique approach to the study of long-term global change and sustainability issues.  The model is distinguished by its treatment of uncertainties through explicit formulation of cultural perspectives on controversial issues, and by its inclusion of a visualisation tool to enable transparent and interactive presentation of scenario analyses.  TARGETS embodies an interdisciplinary approach, deals explictly with both physical and socio-economic uncertainties, and allows diverse interpretations and value patterns to be expressed in global scenario analysis.
