-Until 1999, data of the present source categories 2.D.3.e and f were treated as one source group. From 1990 to 1993 only a rough expert estimation was carried out, which since 1994 in a first step and since 2000 in a second step could be improved by a more detailed data collection that enables to follow the development of source group 2.D.3.e.  Since 2000, the share of this source group accounts for about 5-8% of total NMVOC emissions from solvent-based products with slightly increasing numbers  (Figures 1-2). +Until 1999, data of the present source categories 2.D.3.e and f were treated as one source group.

 Only a slight decrease in the overall NMVOC emissions can be observed since 2009, probably related to the financial crisis and a decline in production.  Only a slight decrease in the overall NMVOC emissions can be observed since 2009, probably related to the financial crisis and a decline in production.

-As the emission data for the 2021 reporting could not be completely revised due to staff constraints and for these reasons the emission data for 2018 had to be updated in last year's reporting, a complete recalculation of the emission data for 2019 and 2020 was carried out for this year's reporting. +Routinely, the NMVOC emissions of the last reported year must be actualized in the next reporting cycle as the final data of the foreign trade statistics are regularly only available after the publication of the respective reporting year has been completed. 
  
-In doing so, it was also possible to take into account the current changes in the systematics of the national production statistics and the foreign trade statistics. +For the year 2020, this adjustment is postponed to the submission 2024 because for some applications the calculation bases also have to be reviewed for further years and this review could not be completed in time for the 2023 reporting.
