Truck Emissions Benefit Calculator (for Class 7 and Class 8)

This calculator allows a user to estimate the weighted emissions benefit of a proposed truck 

project funded under the $1B Goods Movement Emission Reduction Program. Included below 

are the methodology and directions for filling in each field necessary for the emission benefit 

estimation.

Methodology

The methodology presented below comes from the adopted Regulation to Control Emissions 

from In-Use On-Road Diesel-Fueled Trucks. Emissions from trucks are the product of 

population (by model year), annual accrual (miles/year), and pollutant and model year specific 

emission rates (grams/mile). To estimate the project emissions benefit, the emissions from the 

existing truck(s) and replacement truck(s) are calculated. The difference between the two is the 

benefit of that project. See example below:

Calendar Year (CY) 2012: Local Agency A proposes to replace 75 1998 diesel Class 8 trucks 

with 2007 diesel Class 8 trucks. Fleet records indicate that the trucks accrue 30,100 miles/year. 

PM Emission Rate (1998 Model Year in CY 2012) = 0.66 grams/mile

PM Emission Rate (2007 Model Year in CY 2012) = 0.10 grams/mile

Benefit Calculation for Calendar Year 2012

Emissions (75 1998 Model Year Trucks) = 75*0.66 grams/mile*30,100 miles/year = 1,489,950 

grams/year*(1 lb./454 grams)*(1 ton/2000 pounds) = 1.64 tons/year

Emissions (75 2007 Model Year Trucks) = 75*0.10 grams/mile*30,100 miles/year = 225,750 

grams/year*(1 lb./454 grams)*(1 ton/2000 pounds) = 0.25 tons/year

PM Benefit of replacing 75 1998 diesel trucks with 2007 diesel trucks in CY 2012

PM Benefit = 1.64 tons/year – 0.25 tons/year = 1.39 tons/year

This process is repeated for the next four years (project life is 5 years). The total PM emission 

reductions by replacing 75 engine model 1998 trucks is calculated by summing reductions for 

each of the 5 years starting in 2012. The same process is repeated for NOx emissions.

Cost-effectiveness of each project is calculated by computing the total weighted emission

reductions (NOx + 20*PM) over the project life and then dividing by the State contribution.

detail below.

Data Sources

Emission factors for diesel heavy duty trucks are based on in-use testing of Class 7 and Class 8

diesel trucks, which is different than certification data. The emission factors were obtained from 

the On-Road Heavy-Duty Diesel Vehicles (In-Use) Regulation. Since similar data is not 

available for CNG/LNG trucks, diesel emission rates were used for these alternatively fueled

engines (model years 2007 and newer). This methodology will still account for the additional 

benefits of an LNG/CNG heavy duty truck meeting 2010 standards over a diesel heavy duty 

truck meeting 2007 standards. For a hybrid truck, 25% NOx credit is provided (compared to its 

diesel counterpart) in alignment with AB 118.

Shore Power Emissions Benefit Calculator

This calculator allows a user to input information about vessels visiting berth and estimate the 

emissions benefits of a proposed project funded under the $1B Goods Movement Emission 

Reduction Program. Included below are the methodology and directions for filling in each field 

necessary for emissions benefit estimation. Where data is not provided an ARB fleet average 

default will be used. 

Methodology ("Project Calcs")

The methodology presented below comes from the adopted Regulation to Reduce Emissions 

from Diesel Auxiliary Engines on Ocean-Going Vessels while at Berth at a California Port. 

Emissions benefits of a proposed shore power project are a function of the type of vessels that 

call to the berth and how long they hotel while at the berth. Emissions from ocean-going 

vessels are calculated by multiplying the population, frequency of berth visits, hoteling time per 

visit (hours/year), power, load factor and fuel specific emission rates (grams/kW-hr). To 

estimate the project emissions benefits the emissions from the existing vessels using diesel fuel 

and the existing vessels using grid/non-grid power are estimated. The difference between the 

two is the benefit of that project. See example below:

Calendar Year 2014: Local Agency F proposes to install grid power at a particular berth. 

Local Agency F also proposes to make ship modifications to 2 container vessels.

These container vessels have the following characteristics and are projected to visit the berth 

10 times a year in 2014 using grid power.

PM Emission Rate (Marine Distillate Fuel @ 0.1%) = 0.25 g/kW-hr

PM Emission Rate (Grid Power) = 0.01 g/kW-hr

Load Factor = Net Hotelling Load/Total Power

Benefit Calculation for Calendar Year 2014

Emissions (2 Container Vessel at <2000 TEU using Marine Distillate Fuel) 

Emissions = 2 vessels*5200 kW*(1000 kW/5200 kW)*10 visits/year*40 hours/visit*0.25 g/kWhr= 200,000 grams/year*(1 lb/454 grams)*(1 ton/2000 pounds) = 0.22 tons/year

Emissions = 2 vessels*5200 kW*(1000 kW/5200 kW)*10 visits/year*40 hours/visit*0.01 g/kWhr= 8,000 grams/year*(1 lb/454 grams)*(1 ton/2000 pounds) = 0.008 tons/year

Benefits of replacing using Shore power for 2 Container Vessels (<2000 TEU size)

Benefits = 0.22 tons/year - 0.008 tons/year = 0.212 tons/year

Cost-effectiveness of each project is calculated by dividing the weighted emissions reductions 

(NOx + 20*PM) over the project life by the State contribution.

The truck benefits calculator contains the following tabs. Each tab will be described in greater 

detail below.

“Berth Input Data” and “Input” Tabs

In order to estimate the emissions benefits of a proposed project information on each project 

must be entered into the "Inputs" tab (yellow tab) and "Berth Input Data” tabs in this calculator. 

Each user should provide the necessary information for each project. The necessary inputs are 

described in Tables 6 and 7 below. Where no information is available leave the field blank. The 

"Sample Inputs" tab provides sample proposed projects with the correct inputs for those 

projects.

Because this calculator is only set up to estimate the emissions benefits of one berth there is 

one "Berth Input Data" tab. There are multiple "_Inputs" tabs. These tabs correspond to 

compliance years established in the "Guidelines for Implementation" (2012, 2014, 2017 and 

2020 for Grid Power and 2012, and 2014 for Non-Grid Power). The total benefits for the project

compliance year of 2012 for grid power or non-grid power.

The Sample Inputs Tab in the calculator provides four project examples which are described below and the table shows what the 

correct inputs should look like in the calculator. The pull downs are designed to provide only the appropriate options based on the 

project option selected. 

For example, selecting a Replacement project with a class 8 existing truck under “PROJECT DETAILS” will allow only a class 8 

replacement truck as the correct available option under “REPLACEMENT/REPOWER TRUCK ENGINE”. 

Important: Once a project option has been selected and all information has been input in a row for that project option, to make any 

changes, clear all entries and start with a new project option.

Example 1: Replacement

The applicant is proposing to replace a non-drayage class 8 truck (GVWR of 33,001 lbs. and greater) that has a 1972 engine and

reports an annual VMT in California of 50,000. The new truck will be operational in 2012, is a class 8 diesel truck with a 1.20 NOx cert 

level engine, will operate 100% in California, and will have a five year project life. The total project cost is $110,000 and the applicant is

requesting the maximum Prop 1B funding of $40,000.
