This thesis finds that agents must have had a fair opportunity to avoid wrongdoing in order to be responsible and that even in cases where one is not responsible for an act or situation per se, one can nonetheless be obligated to take responsibility for it when it is located within the penumbra of one’s agency. This is the case for some current agents in terms of climate change since the actions of previous individuals and states can be said to have caused suffer-ing for current and future generations, which means that though current agents have not committed these actions, they are also not far enough removed that they should not, in some way, take responsibility for them.
It is possible for future people to be harmed by climate change, since the Non-identity prob-lem can be solved by the Wide Principle and the concept of existential goods. As a result, an adequate theory about the distribution of responsibility for solving the problem of climate change in a non-ideal world, must be able to account for what the people who are hurt by climate change, now and later, are entitled to do in order secure their entitlements and rights. Consequently, the theory must contain considerations about Harm Avoidance Justice as well as Burden Sharing Justice and a theory of when it justified to use one’s Right of Resistance to Global Injustice (RRGI).
Lastly, the thesis finds that none of the commonly discussed principles for distributional jus-tice (PPP, BPP, APP), alone or in the reviewed combinations, can solve a satisfactory amount of the problems related to climate change without causing further problems and that the preferable option is, therefore, a hybrid account of (P)APP and (Q)BPP (variations of APP and BPP) since this combination entails the least problems while solving the widest range of problems regarding climate change.
