  "conversion_comment": "As for `Coal, hard`, and this is the pair #70 opened on: BAFU shipping `Coal, brown` in kg beside `Energy, from coal, brown` in MJ. Both now reach `Brown Coal`, the mass row through this factor and the energy row unconverted. That is safe because the two never appear in the same dataset -- 128 datasets carry the mass, 14 carry the energy, none carries both -- so nothing is counted twice by their sharing a flow. 9.41 MJ/kg is the EF 3.1 LCIA method as implemented by the ecoinvent Centre, matching the factor already carried for ecoinvent's `Coal, brown` onto this target. It is not the IPCC default: Table 1.2 gives 18.9 MJ/kg for sub-bituminous coal and 11.9 for lignite, both well above this."
