Conversion factors
NACE codes (AEA)
B = … + (“1 B 1 a” * 1) + (“1 B 2 a i” * 1) + (“1 B 2 b” * ) + (“1 B 2 c” * ) + …

4. Estimation procedure for Greenhouse gases (CO2, CH4, N2O)
UNFCCC data
Macro “UNFCCC/
CLRTAP to AEA”
CRF-NFR correspondence table
Filled “artificial questionnaire”
Macro “Adjust Totals”
If “Total reported to UNFCCC” differs from “Total AEA”
Final “artificial questionnaire”

CLRTAP data
Macro “UNFCCC/
CLRTAP to AEA”
Macro “UNFCCC to AEA”
Correspondence matrix for the pollutant
Filled “artificial questionnaire”
Macro “Fill empty columns”
If year is missing
EMEP total
Macro “Fill empty pollutant sheet”
If pollutant is missing
EMEP total
CLRTAP data for similar country
Macro “Adjust Totals”
If “Total reported to CLRTAP” differs from “Total AEA”
