Conversion factor C > CO2: 3.67
Calculation of the implicit weighting of the population (IWP)
input fields
I. Input of base data for the determination of a global budget 2020 - 2100 to distribute here            
I. a) Global CO2 budget 2020 - 2100                      
global CO2 budget from 2020 to 2100  in Gt Key findings on remaining CO2 budgets
of the IPCC Sixth Assessment Report Working Group 1:
500 see PDF on the right
 
I. b) Global CO2 budget 2020 - 2100 without LUC and ISA                    
global CO2 emissions without international shipping and aviation (ISA) and without Land use-change (LUC) in 2019 (source EDGAR) 34.9 Gt 88% Info
LUC emissions in 2019 (source Global Carbon Project) 3.8 Gt 10%
ISA emissions in 2019 (source EDGAR)                 1.1 Gt 3%
CO2 emissions total in 2019 (incl. LUC and ISA)[1]             39.8 Gt 100%
global CO2 budget 2020 - 2100 500 Gt * For the determination of the LUC budget, see our separate paper (PDF): Pdf file download icon Stock-Vektorgrafik | Adobe Stock
* LUC budget 2020 - 2100 enter the LUC budget 2020 - 2100 in Gt:  0 0% 0 Gt
ISA budget 2020 - 2100 how much should be reserved from the global budget?  3.0%   -15 Gt
global CO2 budget 2020 - 2100 without LUC and ISA to distribute here             485 Gt
II.) National CO2 budget 2020 - 2100 and calculation of the Implict Weighting of the population (IWP)          
select a country: Germany Please note that this national CO2 budget only refers to CO2 emissions from fossil fuel use and cement production excluding ISA, as the database used here for all countries in the world (EDGAR) also only contains these emissions.

The global CO2 budget calculated under I.b) therefore also only covers these emissions.
share selected country in global population 2019 1.07% national budgets 5.19 Gt ► weighting 100% population in 2019 82.44 Mill.
share selected country in global emissions 2019 1.92% 9.33 Gt ► weighting 100% emissions in 2019 702.20 Mill. t
per capita emissions 8.5 t  
per capita global 4.7 t  
national CO2 budget 2020 - 2100 (basis for calculation IWP) 7.00 [2] Gt This value can be determined from an NDC, for example.
implicit weighting population (IWP) 56%
weighted key 1.44%

Please note that two sources (EDGAR and GCP) have been mixed here. GCP reports a value of around 40.5 Gt in 2019 for total global CO2 emissions.
