 Suppose that we have identified what kinds of interests should be included in a theory of justice, what responsibilities persons owe to future people, and how to treat risk and uncertainty. These can guide us in determining what goals we should aim for. The next question to ask is ‘Who has what responsibilities to meet these goals?’ It is helpful to break this question down into several parts. We can identify four further questions, which together would enable us to answer this question and tell us what would be a just distribution of climate responsibilities.
