英文摘要	Equity and efficiency are two important factors guiding the mitigation of anthropogenic emissions to achieve the Paris climate goals. Previous studies have proposed a range of allocations of global carbon budgets, but few have quantified the equity-efficiency interaction. Based on an investigation of the existing allocation literature, this study conducts a novel analysis using a 'mixed' allocation 'big-data' framework to understand the equity-efficiency interaction in the distribution of global carbon budgets under 2 degrees C and 1.5 degrees C warming targets. At a global scale, a carbon Gini coefficient and aggregate abatement costs are used as quantitative metrics to reflect equity and efficiency, respectively. Results show an equity-efficiency frontier that reflects the opportunity for the international community to co-improve equity and efficiency on top of existing allocations. However, the frontier also features strong trade-offs to further improve equity and efficiency if national allocations are to be achieved individually. Our analysis verifies that such trade-offs are sensitively dependent on the level of global connection and integration. Linking national mitigation actions and potentials can help promote equity-efficiency synergies and contribute to the efficient achievement of the Paris Agreement's temperature and equity goals.
