version history
54.0 Macro "goal seek" improved
53.0 Minor adjustments
52.0 Data EDGAR updated
51.0 Minor adjustments
50.0 Formula determination year emissions neutrality changed
49.0 Error in macro "Goal Seek" corrected (RM 5 was skipped if no solution was found in RM 4)
48.0 Minor adjustments
47.0 Sheets RM, country, IWP and IWP-T with extension "_20" replaced by "IWP-T_RM
46.0 Sheets RM, country, IWP and IWP-T with extension "_20" added to calculate the implicit weighting of the population without taking into account actual emissions after the base year 2019
45.0 Macro "goal seek" improved
44.0 Sheet "output countries": Reference year 2010 replaced by 2019
43.0 Minor adjustments
42.0 Use population figures from EDGAR in the "frozen population figures 2019" choice; IWP sheet: period 2021 - cy (as actual emissions are included in 2020)
41.0 Data EDGAR updated; actual emissions 2020 in the pathways; normalised actual value 2020 in the formulas.
