-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. Information about the current relevance is shown in [[sector:ippu:mineral_industry:start|2.A - Mineral Industry]].+For particulate emissions, Mining is the main emissions source in the Mineral industries. 
 + 
 +In Germany we use two approaches - one for Sands and rocks, one for salts.

 ===== Methodology ===== ===== Methodology =====
Line 18: Line 21:
 With the use of the 2019 GB method [(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/view)], a Tier 2 method is available that can reflect different national conditions. With the use of the 2019 GB method [(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/view)], a Tier 2 method is available that can reflect different national conditions.
  
-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.+In particular, this concerns input variables on humidity and wind speed, which are differentiated into regions. Due to data availability, the regions are represented by the administrative states (German Länder), which does not necessarily represent characteristic weather regimes. Regionality can be increased by merging urban and surface states. Parameters on weather as well as on areas can thus be improved.
  
-With the help of the GB tools, IEFs are reported on an annual basis, which are used for the inventory method AR x EF. Thus the activity data are presented transparently and can be discussed with data suppliers. The emission factors can be modified if further information on the parameters of the GB-tool is available.+The temporal resolution of the regional parameters has limitations: no weather data reports are available on a station basis before 2010, so 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.
  
 +===== Activity Data =====
 +
 +As provided for in the GB model, we use AD in the split hard rock, sand and recycled material. These AD are taken from association information because the national statistics are not complete [(European Industry Association data are published annually at https://uepg.eu/pages/figures. Within the framework of technical consultations, historical data were confirmed by the National Association for Mineral Resources (https://www.bv-miro.org/).)]. Data gaps are interpolated for time series concsistency. The application of the method therefore resulted in higher AD.
 +
 +===== 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.
 +
 +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.

 ===== Recalculations ===== ===== Recalculations =====
  
-Recalculations were necessary due to minor revised AD for the last recent year. +Recalculations were necessary due to revised emissions model parameters for the whole time. Because of the particular weather sensitivity of the model, there are years with higher emissions, which is not counterbalanced by reductions from the area correction. There are changes for the years 1990 to 2009 because of the corrected area data, without specific modeling. The changed weather data can be found in the data set for the adjustment of all years starting in 2010.
