AP-42, Compilation of Air Pollutant Emissions Factors from Stationary Sources, has been published since 1972 as the primary compilation of EPA's emissions factor information. It contains emissions factors and process information for more than 200 air pollution source categories. A source category is a specific industry sector or group of similar emitting sources. The emissions factors have been developed and compiled from source test data, material balance studies, and engineering estimates. The latest emissions factors are available below on this website. Use the AP-42 Chapter webpage links below to access the document by chapter. Emission factors are being updated as data are received and evaluated.
SPECIATE is the U.S. Environmental Protection Agency’s (EPA) database of organic gas and particulate matter (PM) speciation profiles of air pollution sources, which provide the chemical composition of emissions from sources as a percentage of the total weight of PM or organic gas. Organic gas profiles may represent total organic gases (TOG), volatile organic compounds (VOC) or a variation. PM speciation profiles include data for PM of various size classes, such as PM2.5, which represents the mass of particles less than
or equal to 2.5 microns in diameter. In addition to PM and organic gas profiles, SPECIATE contains other profiles such as for nitrogen oxides, mercury and semi-volatile organic compounds (SVOC).
The resource includes an online browser which allows users to view detailed information about the emissions profile in tabular form or bar and pie charts, as well as downloadable databases.
Mapping tool that provides information on permitted facilities in New Jersey. The tool provides information on the reported emissions for each major and minor source, as well as current information on PM and ozone monitored air quality, and community vulnerability information.
Provides guidance for emissions estimation and downloadable spreadsheet based tools for estimating emissions from several different source categories including asphalt plants, concrete plants, combustion sources, and woodworking facilities.
USALEEP (U.S. Small-Area Life Expectancy Estimates Project) provides census-tract–level estimates of life expectancy at birth for nearly all neighborhoods in the United States. Developed by CDC’s National Center for Health Statistics with partners, it uses death records and population data to show how long people are expected to live, on average, in small geographic areas. These data help researchers, health departments, and communities identify and address stark local differences in longevity linked to social, economic, and environmental conditions.
The Louisiana Tumor Registry website presents information about Louisiana’s statewide, population-based cancer registry, which collects detailed data on cancer cases to support prevention, early detection, treatment, and survivorship efforts. It offers resources for cancer registrars and providers on reporting requirements, and for data users—such as public health professionals, clinicians, planners, and researchers—through statistics, interactive data visualizations, cancer maps, monographs, and one-page summaries. The site also describes the Registry’s role in national programs (SEER and CDC’s NPCR), its research infrastructure (including rapid case ascertainment), and how its high-quality data are used to guide cancer control policies and reduce cancer burden and disparities in Louisiana.
The C40 Communication Toolkit for Air Quality is a product of the best practices shared and lessons learned by these cities and is designed to help cities develop clear messaging, harness the power of visuals, and leverage digital communication channels to inspire collective action to improve air quality.
The CDC PLACES (Local Data for Better Health) tool is a free, interactive web resource that provides model-based estimates of chronic disease, health behaviors, preventive practices, disabilities, and related social factors for small geographic areas across the United States. It offers consistent data for all counties, most cities and towns (places), census tracts, and ZIP Code Tabulation Areas, allowing users to view, map, and download neighborhood-level health information to identify local health problems, disparities, and needs and to guide targeted public health planning and policy.
