-Since 1990, so the data, NMVOC emissions from use of solvents and solvent-containing products in general have decreased by nearly 38%. 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.+Since 1990, so the data, NMVOC emissions from use of solvents and solvent-containing products in general have decreased by nearly 55%.

-There are no recalculations+ 
 +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.  
 + 
 +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.

 == Asphalt blowing == == Asphalt blowing ==
 The process of air blowing of asphalt could not only be conducted at oil refineries but also at asphalt processing and asphalt roofing plants. The emissions of air pollutants in that plants depend on various parameters like process conduct and measures to control and abate emissions. All that information is not available to determine the activity rates and emission factors. The Tier 2 emission factors for asphalt blowing in the EMEP/EEA air pollutant emission inventory guidebook 2019 only are uncontrolled emission factors based on US plants before 1980 seeming unsuitable to represent national conditions. Therefore it is planed to gather information to report emissions on a Tier 2 level. That reporting could not start before submission 2022. The process of air blowing of asphalt could not only be conducted at oil refineries but also at asphalt processing and asphalt roofing plants.
