2.D.3.a - Domestic Solvent Use, including Fungicides
The following product groups are taken into consideration:
i) Domestic solvent use
- Laundry detergents, dishwashing detergents and cleaning products (fabric softeners; universal detergents; washing agents; auxiliary washing preparations; dishwashing liquids; detergents for dishwashers; floor detergents; carpet shampooers; car cleaning shampoos; glass cleaners; WC cleaners)
- Care products for footwear, leather articles, furniture, floors and cars
- Polishing agents (for metal)
- Deodorizers (for rooms and others)
- Perfumes (including after shaves; eau de toilette, perfumes)
- Cosmetic and make-up preparations (make-up; hand care products; nail care products; pedicure products; face cleanser; suntan lotions; face and body care products and others)
- Shampoos and hair care products (shampoos; preparations for permanent waving or straightening; hair sprays; lotions and brilliantines; toning shampoos; hair colouring products; hair bleaching and other)
- Other personal care products (shaving creams; personal deodorants and antiperspirants; bath essences; depilatories, deodorants, preparations for intimate hygiene and other)
- Antifreeze agents for cars
ii) Domestic use of pharmaceutical products
‘NMVOC’ is defined in accordance with the VOC definition found in the EC solvents directive. For purposes of the definition of solvents, the term ‘solvent use’ is also defined in accordance with the EC solvents directive.
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:
- Quantities of VOC-containing (pre-) products and agents used in the report year,
- The VOC concentrations in these products (substances and preparations),
- 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.
NMVOC Emission = domestic consumption of a certain product * solvent content * specific emission factor
The calculated NMVOC emissions of different product groups for a source category are then aggregated.
The product / substance quantities used are determined at the product-group level with the help of production and foreign-trade statistics. Where possible, the so-determined domestic-consumption quantities are then further verified via cross-checking with industry statistics.
Calculation of domestic consumption was based on:
- the German production statistics and external trade statistics for the subgroup “Domestic solvent use”.
- turnover values of pharmaceuticals produced in Germany for the subgroup “Domestic use of pharmaceutical products”,
Solvent contents for this product group corresponds to personal information from industrial associations and German literature1).
For alcohol-based cleaning detergents an emission factor of 3% was assumed for calculations 2). For all other products of this source category (e.g. hair spray, after shave, perfumes), an emission factor of 95% was applied.
Discussion of emission trends
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) 3), the 2nd such ordinance (Ordinance on the limitation of emissions of highly volatile halogenated organic compounds – 2. BImSchV) 4) and the TA Luft.
Until 1999, data of the present source categories 2.D.3.a, 2.D.3.h and 2.D.3.i were treated as one source group. Since 2000, a more detailed data collection enables to follow the development of source group 2.D.3.a, which accounts for about 10 – 16% of total NMVOC emissions from solvent-based products.
Only a slight decrease in the overall NMVOC emissions can be observed since 2000. The following four product groups, cause the major emissions in category 2.D.3.a: hair sprays, antifreeze agents for cars, eau de toilette and pharmaceutical products. These four product groups comprise together about 44 – 69% of total emissions.
As emission factors and solvent contents largely remained robust since 2000, domestic consumption of products caused visible changes in NMVOC emissions. For instance, the amount of used ‘antifreeze agents for cars’ per year primarily depends on the weather situation of the specific year. As antifreeze agents have one of the highest domestic consumption values of the category ‘domestic solvent use’, they significantly influence the final value of emitted NMVOC of this category. The increase in emissions in 2010 can be majorly explained by a long-lasting cold season and the need for antifreeze agents. The domestic consumption and hence NMVOC emissions decreased for few product groups, such as personal deodorants, antiperspirants and car surface protectants, compared to the year 2005.
However, domestic consumption and hence NMVOC emissions increased for many product groups, such as soaps, hair sprays, eau de toilette and pharmaceutical products in the same period. Therefore, the emission trend for the complete NFR category is raising in Germany for the period 2005 until 2015.
Uncertainties for emissions for each product were obtained by error propagation and refer to the 95% confidence interval.
For all values based on the official statistics, a relative uncertainty of ±10% was applied. (An exception is the complex value for ‘antifreeze agents for cars’ at ±20%.) Solvent content: For each product, a relative error at ±15% was applied, but not exceeding 100% or falling below 0%. Emission factors: For each product, a relative error at ±15% was applied, but not exceeding 100% or falling below 0%. (An exception is the value for ‘antifreeze agents for cars’ at ±25% based on expert estimation.)
Hence the overall uncertainty of emissions caused by application of products of this source group is 40% with exception of ‘antifreeze agents for cars’ at 60%.
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.
For pollutant-specific information on recalculated emission estimates for Base Year and 2019, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.
At the moment, no category-specific improvements are planned.
