Abstract: The current nationally determined contributions of the Parties to the Paris Agreement are far from being sufficient to achieve the long-term goal to limit global warming. Therefore, the question of how to distribute the global mitigation burden among the Parties in a fair and cost-effective way remains topical. In this paper, approaches based on different fairness criteria and the criterion of cost-effectiveness are applied to a global emission budget compatible with the Paris targets and evaluated for the globally largest emitters including the EU as well as Germany. The results show that domestic mitigation efforts need to be increased in the majority of those countries even more than for the below-2°C limit of the Cancun Agreements. Moreover, even if the cost-effective level is assumed to be reached, there remains a strong need for support by the historical large emitters to others from a fairness perspective.
