Table 1 to Paragraph (c)(2)-Footprint-Based CO2 Target Values
Vehicle type | Footprint cutpoints (ft2) | CO2 target value (g/mile) | |||
Low | High | Below low cutpoint | Between cutpointsa | Above high cutpoint | |
Passenger automobile | 45 | 56 | 71.8 | 0.35 * f + 56.2 | 75.6 |
Light truck | 45 | 70.0 | 75.7 | 1.38 * f + 13.8 | 110.1 |
a Calculate the CO2 target value for vehicles between the footprint cutpoints as shown, using vehicle footprint,f, and rounding the result to the nearest 0.1 g/mile.
Debits = [GWP * (Production) * (AltStd-Std) * VLM] ÷ 1,000,000
Where:
Debits = CO2-equivalent debits for N2O or CH4, in Megagrams, for a test group using an alternative N2O or CH4 standard, rounded to the nearest whole Megagram;
GWP = 25 if calculating CH4 debits and 298 if calculating N2O debits;
Production = The number of vehicles of that test group domestically produced plus those imported as defined in § 600.511 of this chapter;
AltStd = The alternative standard (N2O or CH4) selected by the manufacturer under paragraph (f)(3) of this section;
Std = The exhaust emission standard for N2O or CH4 specified in paragraph (f)(1) of this section; and
VLM = 195,264 for passenger automobiles and 225,865 for light trucks.
