In order to meet the net zero goal that supports the Paris Agreement, global emissions will have to be drastically reduced over the coming years. In fact there is a limit on the remaining amount of emissions that the atmosphere can absorb before the global temperature rise will move above the agreed bounds – this limit is the remaining carbon budget. Global emissions will have to be cut drastically to stay within the budge. The question that this paper considers is how the remaining carbon budget should be allocated, and what might be considered “fair” in this context.
