Which emissions do the national budgets cover here?                    
The national budgets refer basically to CO2 emissions from the use of fossil fuels and from cement production excluding international shipping and aviation (ISA).
Emissions from land-use change (LUC) are therefore not included.
Other CO2 sinks (e.g. technical recapture of CO2 from the atmosphere and geological storage) can be taken into account. But it must be taken in consideration that negative CO2 emissions are also needed to compensate for other greenhouse gases that cannot be avoided. These negative emissions cannot be counted here.
This is also the way the global budget to be distributed here was calculated (see sheet "base data global budget").
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:
