This paper describes an approach to determine the relative accountability that each region and individual nation should bear in reducing atmospheric greenhouse gas. The paper argues that accountability should be based on equity and that all measures of equity for which there are backers should be used in the decision making procedure. Each equity indicator defines a different accountability profile, leading to conflicting prescriptions. Multicriterion decision making methods are seen as having high potential to help design fair compromise profiles, and a methodology is proposed and numerous methods indicated for this purpose. The methodology is illustrated by defining ! 1 different equity indicators and then formulating and solving a multigoai programming model to determine a compromise accountability profile for I 1 multinational regions.
