We develop and formalize a utilitarian notion of responsibility for sustainability which is inspired by Singer's (1972 … welfare maximization, and Brundtland-sustainability. Using a two-generationsresource-model, we find the following …. Sustainability and responsibility for sustainability are equivalent if and only if sustainability is feasible. If it is not, there …
