GHG STANDARDS
5
HD Pickup Truck & Van CO2 Standards
1037.104
• The HD Pickup Truck and Van CO2 emissions standards:
– Begin in 2014MY
– Are CO2 standards, not CREE
– Represent a production-weighted fleet-average standard where all vehicles in
this category form a single averaging set
– The GHG emission standards for these vehicles apply for a weighted average of
55% FTP City and 45% Highway test cycle (new requirement for Federal HD)
where the vehicle is tested at Adjusted Loaded Vehicle Weight (ALVW)

EPA and NHTSA
– As late as manufacturer’s first application submission for a
certificate of conformity
PMY Report - Purpose and Contents

Subconfigurations
1037.104(a)(4), 1037.104(d)(9)
•
May group subconfigurations that have the same equivalent test weight,
GVWR, and GCWR. Assume the curb weight equals two times ETW
minus GVWR.
•
May group together other subconfigurations if use the lowest target value
for any of the subconfigurations
•
Must test at least the greater of 10 subconfigurations or ten percent of
subconfigurations (unless we approve a lower number)
•
At least 90 percent of production volume in the configuration level must be
represented by test data (actual data, data substituted, or analytically
derived)
22
Analytically Derived CO2 (ADC)
1037.104(g)
– Provision allows the use of analytically derived CO2 emission rates based on
baseline test data instead of measured emissions rates
– ADCs are similar to ADFEs used for light-duty vehicles
– Calculated using the equation below, rounded to the nearest 0.1 g/mile
•
•
•
ADC = Analytically derived combined city/highway CO2 emission rate (g/mile) for a new vehicle.
CO2base= Combined city/highway CO2 emission rate (g/mile) of a baseline vehicle.
Road load force coefficients
–
–
–
•
•
ΔF0 = F0 of the new vehicle – F0 of the baseline vehicle.
ΔF1 = F1 of the new vehicle – F1 of the baseline vehicle.
ΔF2 = F2 of the new vehicle – F2 of the baseline vehicle.
ΔAR = Axle ratio of the new vehicle – axle ratio of the baseline vehicle.
ΔETW = ETW of the new vehicle – ETW of the baseline vehicle.
23
ADC Constraints
1037.104(g)
–
The baseline vehicle must (unless we approve otherwise)
– Comply with all applicable emission standards in the model year associated with the ADC
– Include in the pool of tests all official tests of the same or equivalent base engine,
transmission class, engine code, transmission code, engine horsepower, dynamometer
drive wheels, and compression ratio
– May supplement the pool with tests associated with the worst-case engine or transmission
codes and carryover or carry-across engine families
– Must eliminate from the pool tests that were previously used during the model year as
baseline tests in ten other ADC subconfigurations
– Select the tested configuration with the smallest absolute difference between the ADC and
the test CO2 emission rate as the baseline subconfiguration
–
Downward adjustment of ADC from the baseline is limited to ADC values 20 percent below the
baseline emission rate
–
Upward adjustment is not limited
–
No more than 40 percent of the subconfigurations tested in the final CO2 submission may be
represented by ADCs

Production and In-use Standards
1037.104(b)
•
Each vehicle has an in-use CO2 standard that is calculated from the test results and
applies for selective enforcement audits and in-use testing.
– The in-use CO2 standards is equal to the deteriorated emission level * 1.10,
rounded to the nearest 0.1 g/mile
– For multi-fuel vehicles, must determine in-use CO2 standards for each fuel
•
The in-use N2O & CH4 standards are the FEL (no multiplier)
•
Unlike LD GHG IUVP program, manufacturers are not required to perform any GHG
measurements or specific tests for HD pickup trucks and vans
•
EPA In-use Surveillance Testing
–
–
EPA may measure CO2, N2O, CH4 on 2014 and later in-use vehicles
• FTP and Highway cycles only
Any failures or unusual results would need to be addressed by the manufacturer

transparency in implementation of the GHG program
• EPA currently publishes:
• Compliance Report

• EPA does not consider emissions data to be CBI
• For GHG, EPA intends to publish as much non-CBI information for
each manufacturer after the end of the model year as possible

Future Guidance
• EPA will issue guidance on future subjects
when and if necessary.
