CO 2 emissions from unit 12 (1) The responsible person for a unit must determine the quantity of CO 2 , expressed in tonnes, emitted from the unit in each calendar year in accordance with the formula E − C off − C c where E is the quantity of CO 2 emissions attributed to the unit for the calendar year, expressed in tonnes and determined by the formula E u − E th − E int − E ccs + E ext − E ec where E u is the quantity of CO 2 emissions from the combustion of fossil fuel in the unit during the calendar year, determined in accordance with subsection (3), E th is the quantity of CO 2 emissions attributed to the production of useful thermal energy by the unit during the calendar year, determined in accordance with section 21 , E int is the quantity of CO 2 emissions attributed to electricity generated by the unit that is used internally, during the calendar year, at the facility where the unit is located and is (a) equal to zero, in the case of (i) any calendar year in which the unit does not produce useful thermal energy, (ii) any unit, other than a planned unit, that has a commissioning date after December 31, 2024, and (iii) every calendar year after 2049, and (b) determined in accordance with section 22 , in any other case, E ccs is the quantity of CO 2 captured from the unit during the calendar year and stored in a storage project, determined in accordance with section 23 , E ext is the quantity of CO 2 emissions from the production of the hydrogen, ammonia and purchased or transferred steam used by the unit to generate electricity during the calendar year, determined in accordance with section 24 , and E ec is the quantity of CO 2 emissions attributed to the unit for any deduction period during the calendar year, determined in accordance with section 27 ; C off is the quantity of CO 2 , expressed in tonnes, that corresponds to the number of Canadian offset credits remitted for the unit for the calendar year in accordance with section 28 ; and C c is the quantity of CO 2 , expressed in tonnes, that corresponds to the number of compliance credits remitted for the unit for the calendar year in accordance with section 33 . Rounding (2) The quantity determined for E under subsection (1) is to be rounded to the nearest whole number or, if equidistant between two consecutive whole numbers, to the higher number. Combustion of fossil fuel (E u ) (3) The quantity referred to in the description of E u in subsections (1) and 27 (1) must be determined in accordance with (a) section 15 , in the case of a unit that combusted fossil fuel from a coal gasification system during the calendar year; (b) section 16 , in the case of a unit that combusted biomass and combusted fossil fuel from a coal gasification system during the calendar year; (c) section 19 , in the case of a unit that combusted biomass but did not combust fossil fuel from a coal gasification system during the calendar year; and (d) section 15 or 19 , in any other case. Default value (4) Despite subsection (1), the responsible person for a unit may elect to assign a value of zero to any of E th , E int , E ccs and E ec when determining, for the unit, the quantity referred to in the description of E in that subsection. Definition of coal gasification system (5) For the purposes of subsection (3), coal gasification system includes a coal gasification system that is in part located underground.
