Recommended Calculators for Collaborative Projects
Retrofit Calculator (widely applicable for add-on controls).
The Retrofit Calculator is a custom application that will allow
anyone to characterize a fleet and calculate the tons of emission
reductions a retrofit project will generate.
SmartWay Transportation Partnership's FLEET Performance Model (for
The Freight Logistics Environmental and Energy Tracking Performance
Model (FLEET Performance Model) allows a company to quantify
the environmental performance of their fleet operations.
Biodiesel Calculator (for biodiesel only).
Designed to compare diesel fuel oil modified with 0 to 100% biologically
Other Calculator Information of Interest
- The Diesel Emissions Quantifier (Quantifier) is a tool to help fleet owners, school districts, municipalities, contractors, port authorities, and others estimate cost effectiveness and environmental impact of emission reduction technologies that have been added to vehicles and equipment. Estimates are made using specific information about a fleet, such as miles driven, fuel mileage, and others. This site will also help you to prepare and submit your diesel emissions data to EPA.
Biodiesel Board emissions calculator. It gives a general
idea of emissions reductions as a percentage and in lbs based
on the amount of fuel used and the percent BD blend.
British Columbia Biofleet Project's Biodiesel Calculator
National Laboratory's GREET Model.
The GREET (Greenhouse Gases, Regulated Emissions, and Energy
Transportation) Model calculates fuel-cycle energy consumption,
greenhouse gas emissions, and five criteria pollutants in different
transportation fuel/technology combinations. Developed by Argonne
National Laboratory as a Microsoft Excel spreadsheet model, it
allows researchers to evaluate various engine and fuel combinations.
GREET is in the public domain and is available free of charge.
For a given vehicle and fuel system, GREET separately calculates
- Consumption of total energy (energy in non-renewable and renewable
sources), fossil fuels (petroleum, natural gas, and coal),
- Emissions of CO2-equivalent greenhouse gases - primarily carbon
dioxide (CO2), methane (CH4), and nitrous oxide
- Emissions of five criteria pollutants: volatile organic compounds
(VOCs), carbon monoxide (CO), nitrogen oxide
(NOx), particulate matter with size smaller than
10 micron (PM10), and sulfur oxides (SOx)
- EPA's Biodiesel
Custom Alternative Fuels Comparison Chart
- PM Calculator
will calculate controlled emissions for filterable PM2.5 and
filterable PM10 for point sources only.
E-CALC'99 Emissions Calculator. Pace is a tool to calculate
gasoline emissions such as VOCs, Toxics and NOx based on fuel
School Bus Emissions Calculator
- MOBILE6 Vehicle Emission
MOBILE6 is an emission factor model for predicting gram per mile
emissions of Hydrocarbons (HC), Carbon Monoxide (CO), Nitrogen
(NOx), Carbon Dioxide (CO2), Particulate Matter (PM), and toxics
cars, trucks, and motorcycles under various conditions.
Air Resources Board (CARB) Emissions Inventory Data
- EPA's AirData: Access
to Air Pollution Data.
The AirData Web site gives you access to air pollution data for
entire United States. Want to know the highest ozone level
measured in your state last year? Ever wonder where air pollution
monitoring sites are located? Are there sources of air pollution
in your town? You can find out here! AirData
produces reports and maps of air pollution data based on criteria
that you specify.
