The dominant methodological assumptions in climate ethical debates are rational-individualistic. The aim of this paper is to examine whether the rational-individualistic methodological framework is compatible with a theory of moral responsibility for climate change. I employ three fitness criteria of moral agency: a normatively significant choice, sufficient knowledge and control. I demonstrate that the rational-individualistic methodology does not provide a framework in which rational agents meet the three criteria. I conclude that rational-individualistic agents are not fit to be held morally (...) responsible for climate change. The paper demonstrates that the dominant climate-ethical view rests on a methodology that does not allow for a conceptualisation of a moral agent of climate change. (shrink)
