AP-42 Compilation of Air Emissions Factors from Stationary Sources

Description

Primary compilation of EPA's emissions factor information. It contains emissions factors and process information for more than 200 air pollution source categories.

Questions this resource can help answer

What is the emissions rate associated with industrial, commercial, or agricultural sources?

How do I use this resource?

Emissions factors relate the quantity of pollutants released to the atmosphere to an activity that generates pollution. Emissions factors can be multiplied by activity levels to estimate total emissions for a source. The AP42 emissions factors for specific source categories, e.g. solid waste disposal, can be found in specific chapter PDFs.

Model

CoST

The Control Strategy Tool (CoST), developed in 2008, is part of EPA's Emissions Modeling Framework (EMF). CoST is used to estimate emissions reductions and engineering costs associated with control strategies applied to point and area sources of air pollutant emissions to support the analyses of air pollution policies and regulations.

Model

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, available under EPA's Open Source Software policy.

SMOKE

SMOKE is primarily an emissions processing system designed to create gridded, speciated, hourly emissions for input into a variety of air quality models such as CMAQ, REMSAD, CAMX and UAM. SMOKE supports area, biogenic, mobile (both onroad and nonroad), and point source emissions processing for criteria, particulate, and toxic pollutants. For biogenic emissions modeling, SMOKE uses the Biogenic Emission Inventory System. SMOKE is also integrated with the on-road emissions model MOVES.
