| The source category Solid fuels (1.B.1) consists of two sub-source subcategories – the source subcategory Coal mining (1.B.1.a) and the source subcategory Coal transformation (1.B.1.b). This chapter discusses fugitive emissions from coal mining, coal handling, including door leakages from coke ovens and quenching (emissions from the furnace are covered by category 1.A.1.c), and emissions from the beneficiation of solid fuels. In the mining sector, a distinction is made between open-pit mines, in which raw materials are extracted from pits open to the surface, and closed-pit mines, in which seams are mined underground. In Germany, hard coal used to be mined in closed-pits only (until 2018), while lignite is mined in four coal fields since 2003 with the open-pit method only. | The source category Solid fuels (1.B.1) consists of two sub-source subcategories – the source subcategory Coal mining (1.B.1.a) and the source subcategory Coal transformation (1.B.1.b).

| + | Unitil 2018 Germany produced significant amounts of hard coal in underground mines. Since 2019, hard coal has been imported exclusively. NMVOC emissions are considered insignificant as the coal outgased along the import route. Particle emissions from loading and unloading as well as storage are reported under [[sector: | ||

| There are many potential sources of PAH emissions from coking plants. The dominant emission sources are leakages from coke oven doors and from charging operations. As there is limited data available on PAH emissions, the uncertainties of the estimated emission factors are very high. It should also be taken into account that emissions from coke production greatly vary between different coke production plants. The emission factors for benzo[a]pyrene and mixed PAH have been revised by research projects in 2010 [(UBADFIU2010)][(UBABFI2011)]. | There are many potential sources of PAH emissions from coking plants.
