Emission Factor. 1562.4 lbs CO 2 /MWh × (4.536 × 10-4 metric tons/lb) × 0.001 MWh/kWh = 7.09 × 10-4 metric tons CO 2 /kWh (AVERT U.S. national weighted average CO 2 marginal emission rate year 2019 data) Notes: This calculation does not include any greenhouse gases other than CO 2. This calculation includes line losses.
(ii) For catalytic cracking units whose process emissions are discharged through a combined stack with other CO 2 emissions (e.g. co-mingled with emissions from a CO boiler) you must also calculate the other CO 2 using the applicable methods for the applicable subpart (e.g. subpart C of this part in the case of a CO ).
