Which emissions do the national budgets cover here?                    
The national budgets refer to all anthropogenic CO2 emissions (use of fossil fuels incl. ISA, cement production, land-use change and other CO2 sinks (e.g. technical recapture of CO2 from the atmosphere and geological storage)).
It must be taken into account that negative CO2 emissions are also needed to compensate for other greenhouse gases that cannot be avoided. These negative emissions cannot be counted here.
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.

AW:
To calculate the share of the EU or EU member states in global emissions, the emissions according to the EEA are set in relation to global CO2 emissions according to the GCP.

Restriction:

The EEA shows LULUCF emissions and GCP LUC emissions.

For simplicity, it is assumed here that LUC = LULUCF.
