Significant gaps exist in the effectiveness of attempts to address human rights violations of the private sector through domestic law, international law, and civil regulation, leaving the world with no single effective response to rights violations by corporations. This paper will analyze each model and propose a new option for holding the private sector accountable, grounded in international law but drawing on lessons provided by other paradigms. This paper proposes a binding Fourth Optional Protocol to the UNCRC, to incorporate the Corporate Social Responsibility movement into non-binding international instruments that would bridge current gaps in the international protection of children’s rights.
