-\\+Quarrying & Mining is the main source for particulate matter emissions within the entire **Mineral industries sub-sector (2.A)**.
  
-Regarding particulate emissions, Mining is the main emissions source in the Mineral industries. 
- 
-In Germany, two diffrent approaches are applied for sands and rocks, and for salts, respectively. 
  
 ===== Short description ===== ===== Short description =====
  
-The mining process emits relevant amounts of particles. Quarrying and mining of minerals other than coal is subsumed, in particular mining of limestone, hard rock and building Sands, with rising recycled materials.+Generally, mining processes emit relevant amounts of particles. 
  
-Salt production is a sub-category of the mining activities in respect of the country specific approach used.+**NFR 2.A.5.a - Quarrying and mining of minerals (other than coal)** includes the mining of limestone, hard rock, and building sands, as well as the increasing use of corresponding recyclates.
  
-The Tier 1 methodology for the emissions from salt mining represents only a small portion of emissions from this sector - few than 4%, depending on the PM fraction. Considering the limited scale of the activity and emission, the part is considered to be below the significance for higher Tiers.+Due to the country-specific approach applied, the production of (potash and rock) salt is a sub-category of the mining processes considered in the German air pollutant emissions inventory.

 ===== Methodology ===== ===== Methodology =====
  
-With the use of the 2023 GB method [(EMEP/EEA, 2023: EEA Report No 06/2023 EMEP EEA air pollutant emission inventory guidebook 2023, Copenhagen, 2023; URL: https://www.eea.europa.eu/publications/emep-eea-guidebook-2023/part-b-sectoral-guidance-chapters/2-industrial-processes-and-product-use/2-a-mineral-products/2-a-5-a-quarrying-1/view)], a Tier 2 method is available that can reflect different national conditions.+Withi the German air pollutant emissions inventory, different approaches are applied for (i) sands and rocks, and (ii) salts:
  
-In particular, this concerns input variables on humidity and wind speed, which are localized according to the administrative states of Germany. Larger city states (Berlin, Hamburg and Bremen) were merged with the respective larger states (Brandenburg, Schleswig-Hollstein, Niedersachsen) as the city states do not neccessarily represent the local weather conditions.  +**Sands and Rocks**
-Parameters on weather as well as on areas can thus be improved in the model above. In a first this was done by using weather data from the German Weather Service (DWD), which may be obtained as daily station data from the Open Data Portal: ClimateDataCenter (CDC) of the DWD URL: https://opendata.dwd.de/climate_environment/CDC/observations_germany/climate/daily/kl/+
  
-No area information from the Corine land cover before 2010 is used (consistent data sets). In addition, information from CLC category 131 (Mineral extraction sites [(Copernicus 2019: CLC-classes; URL: https://land.copernicus.eu/user-corner/technical-library/corine-land-cover-nomenclature-guidelines/html/index-clc-131.html)]) had to be adjusted for areas of active open-pit lignite mines.+By applying the 2023 GB method [(EMEPEEA2023)], a tier2 method is available reflecting different national conditions, in particular specific input variables on humidity and wind speed, which are localized according to  
 +the German federal states. Here, as the three German city-states (Berlin, Hamburg, and Bremen) do not represent average weather conditions,  they are considered part of the surrounding federal states (Brandenburg, Schleswig-Hollstein,  
 +and Niedersachsen).  
 +Parameters on weather as well as on areas can thus be improved in the model mentioned above.  
 +In a first approach, this was done by using weather data from the German Weather Service (DWD), which can be obtained as daily station data from (DWD, 2024) [(DWD2024)]. 
 +No area information from the Corine land cover before 2010 is used (consistent data sets). In addition, information from CLC category 131 (Mineral extraction sites) had to be adjusted for areas of active open-pit lignite mines. (Copernicus, 2019) [(COPERNICUS2019)] 
  
-For salt production currently a Tier 1 method is used: information on production of salts are multiplied with country specific emission factors for TSP and PM. Please see the small relevance of this under trend diskussion.+**Salts** 
 + 
 +Salt mining represents only a minor portion (less than 4%, depending on the PM fraction) of the particulate-matter emissions reported for NFR 2.A.5.a.  
 + 
 +With respect to this limited scale of both activity and emissions, salt mining is considered too insignificant for the application of a higher tier (Please see trend discussion below). 
 +Therefore, in contrast to the mining/quarrying of sands and rocks described above, a tier1 approach based on information on production of salts and country-specific emission factors for TSP and PM is applied. 
  
 ===== Activity Data ===== ===== Activity Data =====
  
-As provided in the Guidebook model, specific AD for hard rock, sand, and recycled material are applied.  +**Sands and Rocks** 
-Because of incomplete national statistics, these AD are taken from nationals and international association information [(European Industry Association data are published annually at https://www.aggregates-europe.eu/facts-figures/figures/)]. Within the framework of technical consultations, historical data were confirmed by the National Association for Mineral Resources [(https://www.bv-miro.org/)]. Now we are additionally in contact with Federal Institute for Geosciences and Natural Resources for figures og mineral raw materials [(https://www.bgr.bund.de/DE/Themen/Min_rohstoffe/Produkte/produkte_node.html)]. + 
-For time series concsistency, data gaps are closed via interpolation or expert adjustement.+As provided in the calculation model presented with the EMEP/EEA Guidebook, specific activity data for hard rock, sand, and recycled material are applied.  
 +Here, due to incomplete national statistics, these specific AD are taken from national and international association information available from Aggregates Europe – UEPG (2024) [(UEPG2024)].  
 + 
 +Within the framework of technical consultations, historical data were confirmed by the National Association for Mineral Resources [(BVMIRO2024)].  
 + 
 +However, additional information and figures on mineral raw materials are compiled by the Federal Institute for Geosciences and Natural Resources (BGR) [(BGR)] but are not yet available. 
 + 
 +Therefore, for time series consistency, data gaps are closed via interpolation or expert adjustments. 
 + 
 +**Salts**  
 + 
 +Production data for potash and rock salt are included in national statistics, with data gaps being filled as already described for sands and rocks above.  
 +Here, as potash salt is dominating, all reported emissions are modelled as resulting from potash salt. 
  
-The data from national statistics includes production of potash and rock salt. Potash salt is dominating, nevertheless gaps of statistics are filled and emissions are modelled as potash salt only. 
  
 ===== Emission factors ===== ===== Emission factors =====
  
-The calculation of emissions takes into account national circumstances and reduction measures.The calculations are available in total more than ten Excel files (individual years since 1990, annually from 2010). Since the GB tool in principle calculates emissions for exactly one year [(EMEP/EEA, 2019: EEA Report No 13/2019 EMEP EEA air pollutant emission inventory guidebook 2019, Copenhagen, 2019; URL: https://www.eea.europa.eu/publications/emep-eea-guidebook-2019/part-b-sectoral-guidance-chapters/2-industrial-processes/2-a-mineral-products/2-a-5-a-quarrying-1/view)], files must be available for exactly those years in which input data are available. Intermediate years are interpolated in case of data gaps.+**Sands and Rocks** 
  
-With the help of the GB tools, IEFs are estimated on an annual basis, which are used for the inventory method AR x EF. The emission factors are virtual, but the calculation of this is modified by national circumstances on the parameters. So we would name the EF as country-specific.+As described above, the calculation model provided by the EEA as part of the EMEP/EEA GB takes into account national circumstances and reduction measures. 
 +The calculations are available in from of more than ten MS Excel files (individual years since 1990, annually from 2010). 
 +Since the GB tool in principle calculates emissions for exactly one year [(EMEPEEA2023)], files must be available for those years for which specific input data are available.  
 +In case of data gaps,  intermediate years are interpolated . 
 + 
 +With the help of the GB tools, annual implied EFs are estimated which are used for the inventory method (EM = AR x EF).  
 +As the calculation of this implied emission factors is influenced by national circumstances and weather conditions, the EF are consideres as being country-specific. 
 + 
 +**Salts**
