Diesel Emissions Quantifier

EPA's Diesel Emissions Quantifier (DEQ) 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.

MOtor Vehicle Emission Simulator (MOVES)

EPA's MOtor Vehicle Emission Simulator (MOVES) is a state-of-the-science emission modeling system that estimates emissions for mobile sources at the national, county, and project level for criteria air pollutants, greenhouse gases, and air toxics.

Alternative Fuel Life-Cycle Environmental and Economic Transportation (AFLEET)

The Department of Energy's Technology Integration Program has enlisted the expertise of Argonne National Laboratory to develop a tool to examine both the environmental and economic costs and benefits of alternative fuel and advanced vehicles. Alternative Fuel Life-Cycle Environmental and Economic Transportation (AFLEET)helps stakeholders estimate petroleum use, greenhouse gas (GHG) emissions, air pollutant emissions, and cost of ownership of light-duty and heavy-duty vehicles.

COBRA

EPA's CO–Benefits Risk Assessment (COBRA) screening model is a free tool that helps state and local governments explore how human health outcomes change from clean energy policies and programs that improve air quality, quantify those health outcomes economically, and map and visually represent these changes in health outcomes and air quality.

Air Data

EPA's Air Data site gives you access to air pollution data for the 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.

AirNow

AirNow highlights air quality in your local area first, while still providing air quality information at state, national, and world views. AirNow is a partnership of the EPA, National Oceanic and Atmospheric Administration (NOAA), National Park Service, NASA, Centers for Disease Control, and tribal, state, and local air quality agencies.
