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.

EJScreen

EPA's Environmental Justice Screening and Mapping Tool (EJScreen) is an environmental justice mapping and screening tool that provides EPA with a nationally consistent dataset and approach for combining environmental and demographic socioeconomic indicators.

CalEnviroScreen

CalEnviroScreen is a mapping tool, developed by the California Office of Environmental Health Hazard Assessment, that helps identify California communities that are most affected by many sources of pollution, and where people are often especially vulnerable to pollution's effects.

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.

Greenhouse Gas Equivalencies Calculator

EPA's Greenhouse Gas Equivalencies Calculator allows you to convert emissions or energy data to the equivalent amount of carbon dioxide (CO2) emissions from using that amount. The calculator helps you translate abstract measurements into concrete terms, such as the annual emissions from cars, households, or power plants. This calculator may be useful in communicating your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing greenhouse gas emissions.

Climate and Economic Justice Screening Tool

The Council on Environmental Quality developed the Climate and Economic Justice Screening Tool which has an interactive map and uses datasets that are indicators of burdens in eight categories: climate change, energy, health, housing, legacy pollution, transportation, water and wastewater, and workforce development. The tool uses this information to identify communities that are experiencing these burdens and to help federal agency's achieve President Biden's Justice40 Initiative.

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.
