Detailed mathematical description of the RM Scenario Types: Zenodo
If the actual emissions were entered for 2020 but not for 2021:
In deviation from the 'normal' formula given in the mathematical description, the emissions in 2021 refer to the normalised emissions in 2020 (row 102). This takes into account the temporary effect in 2020 due to Corona.
If an actual value has also been entered for 2021, E_2020_normalised is not used.
