For Richer or for Poorer? The Role of Science, Politics, and Ethics in the Global Climate Change Policy Debate

Abstract

Addressing the issue of global climate change (GCC) requires the cooperation of all nations of the world. Although the industrial nations of the north have the financial and technological resources to begin addressing the problem, they ultimately remain vulnerable to the actions of the developing nations of the south. The negotiation process—now a decade old—has, thus far, failed to produce a universal agreement on greenhouse gas (GHG) reductions. This failure is attributed to the lack of a unifying principle capable of overcoming the short-term differences in interest among the two groups of countries. Science and politics, the two forces driving the GCC debate, have inherent weaknesses that prevent them from providing the leadership necessary to secure universal cooperation in combating this major threat to the global environment. Ethics, specifically the principles of equity and justice, is proposed as a possible unifying principle. An analysis of the four main issues that must be resolved before a universal agreement to combat GCC can be negotiated—the appropriate level for GHGs, the proper distribution of GHG emission rights, the best actions for attaining the appropriate GHG level, and the form of the institutional arrangements that will be necessary to carry out these actions—indicates that ethical considerations can and must inform and delineate appropriate bounds for science, economics, and politics. Guaranteeing the equitable and just distribution of rights and responsibilities in a global climate change regime offers the best prospect for such a regime to be made possible.
