Reports model-predicted air quality concentrations and health impacts in 13,189 urban areas worldwide
The air quality trends summaries are intended to reflect actual air quality and therefore include concentrations that may have been impacted by episodic events like wildfires and dust storms.
AirCompare maps provide information for counties that monitored outdoor air quality in the last five years and tailor that information for groups more likely to be affected by different levels of pollution.
The Database of State Incentives for Renewables & Efficiency (DSIRE) is the most comprehensive public clearinghouse for information on financial incentives and policies that support renewable energy and energy efficiency in the United States.
Population projections that account for both Shared Socioeconomic Pathways and Representative Concentration Pathways
This open collection is designed to support and enhance global research initiatives focused on understanding and mitigating the health impacts of environmental exposures.

Provides access to downloadable emissions data for point industrial sources and coal burning operations
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.
