What are emissions targets for the world's six largest emitters that sum up to Paris-compatible emissions?
To answer this question, this paper shows top-down exemplary national emission paths that are derived from a remaining global CO2 budget using the Regensburg Model, which is based on converging per capita emissions.
The Paris Ambition Mechanism is based on a bottom-up approach. However, if the national targets are not Paris-compatible in total, the question arises whether national targets represent an adequate contribution to the necessary global efforts. Results in the Regensburg Model can be interpreted as a lower limit for the ambitions of industrialised countries.
A discourse on global framework data and distribution keys of a global CO2 budget can contribute to Paris-compatible NDCs in sum.
