Thierry Ngosso Habilitationsprojekt: Firms and Climate Responsibility Climate change poses a serious threat to the ecological equilibrium of the planet and could plague the well-being of future generations. Hence climate change mitigation is one of the most urgent and important debates in contemporary politics. The consensus about this peril is still relative and recent. Be it as it may, scholars and policy makers have focused on the following issues: 1) should we prohibit luxury pollution in order to prevent the harm climate change will otherwise cause? 2) If indeed we ought to reduce our emissions, how should we allocate the burden of climate change mitigation? But scholars in climate justice have not sufficiently dealt with the following issue: who should take action in order to achieve climate justice? Or, in other words, who should be the agents of climate justice? Climate justice tends to assume that, as a primary agent of justice, states are the primary duty-bearers of climate change mitigation. The question of what climate justice requires from other agents or institutions like business corporations remains neglected to a certain extent. Although climate justice encourages business corporations, as secondary agents of justice to take initiatives to reduce their own emissions of greenhouse gases, it does not treat them as political actors. Although this is a step in the right direction, it remains largely insufficient to address the threats related to climate Change. The main objective of this research project is to fill this gap by investigating on the special contribution of business corporations to climate justice as political entities. This research project will do so by elaborating a new argument for climate obligations of business corporations. This argument will be built on the analogy between the duty of assistance and the duty of just savings in Rawls’s theory of justice. Scholars like Hsieh argue that we should extend the duty of assistance to business corporations in order to achieve global justice. Our main hypothesis is that we should extend the duty of just savings to business corporations in order to achieve intergenerational justice. This project aims at making three main contributions. First, it will make an academic contribution to the climate justice debate, to global ethics and to business ethics. Second, the project aspires to contribute to the post-Kyoto international agreement by clarifying the role business corporations should play as political actors. Third, at practical level, it will contribute to advancing and encouraging responsible practices in business corporations.
