This article contributes to research in Political Corporate Social Responsibility (PCSR) by developing the idea of “political corporate social irresponsibility” (PCSiR). PCSiR occurs when corporations provide what are expected to be public goods but, in so doing, create or exacerbate public problems and diminish social welfare. We examine PCSiR through the case of a “garbage mountain” located near Tripoli City, Lebanon. This accumulation of solid waste is a potent symbol of the corporate failure in delivering contracted social services. We question (...) how and to what extent has the power and influence of political actors in Lebanon hindered environmental protection and sustainable business practices. In response, we investigate the relations between corporations, the state and civil society that led to the garbage mountain and corporate response to political activism. Drawing on a neo-Gramscian approach to PCSR, we show how an interplay of consent and coercion fosters effective PCSiR, shielding those in power from responsibility for their self-serving behavior.
