g CQ2 | [SIGMA] (VMTP1,P2,P3 x CO2 factor)trip | |
____________________ | = | _________________________ |
PMT | [SIGMA] (VMTP3 x occupancy)trip |
Where:
VMTP1,P2,P3 equals VMT in miles (sum of Periods 1, 2 and 3) of trips for all vehicles (sum of Periods 1, 2, and 3) by BEVs and FCEVs
VMTP3 equals VMT in miles for the Period 3 portion of a trip
CO2 factor equals the CO2 emission factor in grams CO2 per mile as provided in Table 2 and Table 3
Occupancy equals the compliance occupancy value in the unit of passengers determined by Table 4
