71  Caustic calcined magnesia
 (1) Tonnes of caustic calcined magnesia that:
 (a) has a minimum magnesium oxide (MgO) content of 75% by mass; and
 (b) is burned between 650°C and 1200°C; and
 (c) is produced as part of carrying on the magnesia production activity at the facility; and
 (d) is of saleable quality.
 Note: Due to the definition of saleable quality, inputs that are transformed into saleable magnesia which is then re‑calcined are only counted once.
 (2) The metric in subsection (1) is applicable to a facility that conducts the activity of producing caustic calcined magnesia through the physical and chemical transformation of magnesite (magnesium carbonate (MgCO3)) in a furnace into caustic calcined magnesia (the magnesia production activity).
 Note: Caustic calcined magnesia may also be transformed into deadburned magnesia and electrofused magnesia at the facility, which involves burning or fusing at higher temperatures than in paragraph (1)(b).
 (3) The default emissions intensity is 1.51 t CO2‑e per tonne of caustic calcined magnesia.
