-NMVOC emissions are calculated in keeping with a product-consumption-oriented approach. +NMVOC emissions are calculated in accordance with a product-consumption-oriented approach. 
 In this approach, solvent-based products or solvents are allocated to the source category, and then the relevant NMVOC emissions are calculated from those solvent quantities via specific emission factors. Thus, the use of this method is possible with the following valid input figures for each product group: In this approach, solvent-based products or solvents are allocated to the source category, and then the relevant NMVOC emissions are calculated from those solvent quantities via specific emission factors. Thus, the use of this method is possible with the following valid input figures for each product group:
   * Quantities of VOC-containing (pre-) products and agents used in the report year,   * Quantities of VOC-containing (pre-) products and agents used in the report year,
   * The VOC concentrations in these products (substances and preparations),   * The VOC concentrations in these products (substances and preparations),
   * The relevant application and emission conditions (or the resulting specific emission factor).   * The relevant application and emission conditions (or the resulting specific emission factor).

 The quantity of the solvent-based (pre-)product corresponds to the domestic consumption which is the sum of domestic production plus import minus export. The quantity of the solvent-based (pre-)product corresponds to the domestic consumption which is the sum of domestic production plus import minus export.

-Since 1990, so the data, NMVOC emissions from use of solvents and solvent-containing products in general have decreased by nearly 38%. +Since 1990, so the data, NMVOC emissions from use of solvents and solvent-containing products in general have decreased by nearly 55%. 
  
 The main emissions reductions have been achieved in the years since 1999. This successful reduction has occurred especially as a result of regulatory provisions such as the 31st Ordinance on the execution of the Federal Immissions Control Act (Ordinance on the limitation of emissions of volatile organic compounds due to the use of organic solvents in certain facilities – 31. BImSchV), the 2nd such ordinance (Ordinance on the limitation of emissions of highly volatile halogenated organic compounds – 2. BImSchV) and the TA Luft. The main emissions reductions have been achieved in the years since 1999.

 ===== Recalculations ===== ===== Recalculations =====
  
-There are no recalculations. +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.  
 + 
 +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.
