Abstract
Reference to responsibility is prominent in discussions of climate change of every kind. Certain dimensions of the issue call it forth. These include, above all, the planetary scale of the problem and the corresponding sense of endangerment, along with lack of clarity on what exactly needs to be done and who should do it. The question of planetary responsibility has been around for some time. The limits to growth debate of more than 40 years ago already indicated concern about the ecological limits of industrial civilization (Meadows et al., 1972; Meadows et al., 2004). In this light, the article reviews and takes inspiration from key philosophical conceptualizations of global ecological responsibility before it goes on to add a necessary sociological approach that reveals the democratic, communicative mechanisms that might make it realizable.
