The claim that corporations have human rights obligations remains contentious and can be fraught with confusion. This article synthesizes existing corporate human rights theory and responds to objections to the idea that transnational corporations (TNCs) have human rights obligations. The argument proceeds in three stages. The first section describes the different forms TNCs take and explains why TNCs are properly understood as moral agents responsible for their policies and practices. The second section reviews and explains different philosophical theories of corporate human rights obligations. The third section articulates and responds to objections to the idea that corporations have human rights obligations. The main conclusion of this article is that there are multiple, compelling and overlapping justifications of corporate human rights obligations.
