This article examines the emerging State practice on the evolving corporate social responsibility (CSR) standard. It examines its public international law instruments and particularly analyses the role of States in the development of CSR norms and the potential of these norms to impact the recognition, promotion and protection of human rights. The article also assesses the UN effort to consolidate the standards that have emerged from soft law instruments in public international law, focusing on the Ruggie’s process and its potential impact on the future development of the law and practice in this area. The article shows an emerging convergence of standards and practices and coherence on certain themes that could ultimately lead to the establishment of stronger international norms on CSR. A key example is human rights standards for corporations regarding their activities in host States.
