Resource Type: Database
Primary compilation of EPA's emissions factor information. It contains emissions factors and process information for more than 200 air pollution source categories.
Envirofacts is the EPA's primary "one-stop shop" for environmental data. It acts as a data warehouse that integrates information from dozens of different EPA regulatory databases into a single, searchable interface
Mapping tool to display, query, and export information on emissions and air quality in Wisconsin.
The Air Quality Life Index (AQLI) converts air pollution concentrations into their impact on life expectancy. Through the AQLI’s hyper-local data, users anywhere on Earth can zoom into their district and see how much longer they would live if policies were to reduce pollution to meet the World Health Organization’s guideline, a national standard, or a user-defined target. This information can help inform local communities and policymakers about the benefits of air pollution policies in perhaps the most important measure that exists: longer lives.

The Air Quality System (AQS) contains ambient air pollution data collected by EPA, state, local, and tribal air pollution control agencies from over thousands of monitors. AQS also contains meteorological data, descriptive information about each monitoring station (including its geographic location and its operator), and data quality assurance/quality control information.
Real TIme Geospatial Data Viewer (RETIGO) is a free, web-based tool that can be used to explore environmental data that you have collected either stationary or in motion (e.g., air quality sensors added to a bike).
High-resolution, map-based decision-support tool launched in Fall 2023. It was co-developed by the non-profit American Forests alongside a council of local stakeholders, including city governments, state agencies, and community advocates.
