coking coal
solid coalDESNZ 2025 'Coking Coal' — the metallurgical grade coked for steelmaking, and the highest-emitting of DESNZ's four coal rows at 3164.65002 kgCO2e/tonne (industrial coal is 2395.28994). IPCC 2006 also lists coking coal separately (NCV 28.2 MJ/kg, CO2 94,600 kg/TJ): a different figure from a different source, shown for reference and never averaged with this one. No density is recorded (coal is sold by mass).
- Coal energy and emission factors vary widely by rank, region and moisture/ash content. This entry is DESNZ 'Coking Coal' (UK context). No density is available (coal is sold by mass), so volume conversions are not available.
