Vehicle Emissions: Technical Tools
Models and technical studies used to calculate motor vehicle and diesel emissions

MOBILE6 is an emission factor model for predicting gram per mile emissions of Hydrocarbons (HC), Carbon Monoxide (CO), Nitrogen Oxides (NOx) , Carbon Dioxide (CO2), Particulate Matter (PM), and toxics from cars, trucks, and motorcycles under various conditions. This page provides technical and policy information on the use of Mobile6 as well as training materials

The International Vehicle Emissions (IVE) Model is a computer model designed to estimate emissions from motor vehicles in developing countries. The model is free and can be downloaded from this link. The model will help cities and regions develop emissions estimates to:

  • Focus control strategies and transportation planning on those that are most effective;
  • Pedict how different strategies will effect local emissions; and
  • Measure progress in reducing emissions over time.

The model includes local air pollutants, greenhouse gas emissions, and toxic pollutants.

Why is it needed?

Emissions from vehicles in most countries, particularly developing countries, are not well understood, and the ability to make accurate future emissions estimates does not presently exist. This, in turn, limits the ability of decision-makers to design effective control strategies. Only a few countries, such as the U.S. and Europe have developed reasonably accurate emissions projection tools, and these models are designed only for their respective regions. The U.S. and European models cannot take into account the differing technologies and conditions that exist in most developing countries. Most of these existing models do not include the full range of global warming and local toxic emissions that are needed to fully evaluate the impact of motor vehicles. The International Vehicle Emissions (IVE) Model is specifically designed to have the flexibility needed by developing nations in their efforts to address mobile source air emissions.

This model predicts emissions of exhaust, diurnal, and refueling hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NOx), sulfur oxides (SOx), exhaust particulate matter (PM), carbon dioxide (CO2), as well as volume of fuel consumed by all types of mobile nonroad equipment except locomotives, aircraft, and commercial marine vessels. This page has downloadable software and technical papers, the user's guide and training materials

The EPA's heavy-duty diesel fuel analysis program seeks to quantify the air pollution emission effects of diesel fuel parameters on various nonroad and highway heavy-duty diesel engines. The program will examine the hydrocarbon (HC), oxides of nitrogen (NOx) and particulate matter (PM) emission impacts of diesel fuel parameters including such parameters as cetane number, aromatics content, and fuel density. This website provides technical documents on certane number and other fuel characteristics on diesel emissions,
