Which emissions do the national budgets cover here?                    
The national CO2 budgets cover all anthropogenic CO2 emissions (use of fossil fuels including ISA, cement production and land use).
Limitations of the results:
EEA, EDGAR and UBA are using LULUCF for land use.
However, LUC should be offset against the CO2 budgets according to the IPCC. But LUC is not reported.
For global emissions, LUC was taken into account according to the GCP.
This results in an inconsistency in the data used (see the ‘base data global budget’ sheet for the differences).
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.

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.

However, LUC emissions according to GCP would have to be offset against the IPCC budgets (see  “base data global budget” sheet).
