Which emissions do the national budgets cover here?                    
The national budgets refer to all anthropogenic CO2 emissions exlusive ISA. GCP uses three different sources for LUC, which can vary significantly. The mean value was used here, as GCP also does at the global level.
Extended Smooth Pathway Model (ESPM)                      
Basic idea behind the ESPM:
1. National budgets: A predefined global CO2 budget is distributed to countries. The ESPM offers the weighted distribution key also used here for this purpose.
2. National paths: The ESPM offers the Regensburg Model Scenario Types RM 1 - 6 to derive plausible national paths that adhere to a national budget.

The national budgets calculated here can be used in the following web application to calculate different national emission paths that all adhere to the given budget:

See the ‘Data export’ sheet for the data required there.
