global CO2 budget 2020 - 2100 including LUC and excluding ISA             629  Gt used in the sheet "EU GCP"
LUC and ISA emissions must be subtracted when using the EDGAR database, as the emissions for all countries in the world do not include these emissions there. * For the determination of the LUC budget, see our separate paper:

Tools for determining global paths                      
Based on a predetermined global CO2 budget from 2020, the following web app can be used to calculate global emission paths with the RM Scenario Types:
http://paths.climate-calculator.info/
Furthermore, an Excel tool is offered that provides even more input and analysis options:
