Paris-compatible national CO2 budgets

Description

Based on the distribution of a global CO2 budget to countries using a weighted distribution key that takes into account the shares of emissions and population in a base year, this tool can be used to calculate Paris-compatible CO2 budgets for all countries in the world.

This weighted distribution key reflects the two most important factors "current reality" and "climate justice".

Here is a preview of the Excel tool.
