Due to the limitations of national and international legal systems in dealing with these actors, it is necessary to explore alternatives, which go beyond the traditional legal framework, to ensure companies’ compliance with human rights standards. One of the options is the use of transnational private regulations (TPR); this possibility was however not addressed in depth by legal literature until now. The PhD project aims at demonstrating that TPR mechanisms have the potential to achieve effective corporate compliance with human rights standards. In order to do so, this research analyses six regulatory frameworks from different fields using an interdisciplinary approach between Law, Sociology and Economics. To assess the effectiveness of TPR’s compliance mechanisms when targeting human rights issues, the process of human rights impact assessment is used.
