Abstract
Current Integrated Assessment Models (IAMs) and general carbon budget models do not sufficiently account for climate justice in their allocations of future emissions. To address these limitations, several modeling frameworks such as equal per capita (EPC) and per capita convergence (PCC) that aim to incorporate fairness and justice more comprehensively into emissions attribution and carbon budget allocation have emerged. We propose a novel integrated attribution – allocation (IAA) model construct that robustly incorporates three equity principles of responsibility, capability, and equality into the estimation of carbon budget emissions allocations. Results demonstrate that simple reductions of responsibility for climate action to categories such as global south vs global north and developed vs developing cannot be established a priori as methodologies for fairly and justly assigning emissions rights and mitigation obligations.
