Distribution of a Global CO2 Budget - A Comparison of Resource Sharing Models
In view of the connection between the cumulative CO2 emissions and global warming, as described in the IPCC reports, the key question arises how a globally remaining budget could be realistically distributed among countries. The discussion of this issue can contribute to NDCs that are Paris-compatible in sum.
Resource sharing models directly address the allocation of such a remaining global budget. This article will therefore give an overview of the properties of resource sharing models that, in principle, use current emissions and population as a distribution key. With the current emissions, the current reality and with the population climate justice can be mapped.
We also identified a possible additional helpful assessment criterion for NDCs: the implicit weighting of population.
