===== Method ===== | ===== Method ===== | ||

+ | === General procedure === | ||
+ | |||
+ | NMVOC emissions are calculated in keeping 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. | ||
===== Discussion of emission trends ===== | ===== Discussion of emission trends ===== | ||
+ | === General information === | ||
+ | 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. | ||
+ | |||
+ | === Specific information === | ||
+ | Since 1990, data of source category 2.D.3.g are recorded. Since 2000, a more detailed data collection procedure enables to follow the development of different applications, | ||
+ | |||
+ | Total emissions of NMVOC emissions of 2.D.3g remain relatively stable. In some major activities amounts of NMVOC emissions raised, such as from solvents used in polystyrene foam processing and the manufacture of solvent-based consumer products. | ||
