This mapping tool visualizes emissions data (criteria and toxic air pollutants) from permitted facilities in Richmond, California. The tool also provides information on the sensitive populations in the area and incorporates CalEnviroScreen 3.0 data as a customizable background layer. Users can select individual facilities, view their reported emissions, filter the results by pollutant, facility, or census tract, and download the underlying data.
- For best visualization: Click on the full-screen icon at the bottom right corner.
- To download data from an individual plot or map: Click on the map/plot and then click on the download icon at the bottom right.
- To undo all filters: Click on the reset icon at the bottom right corner of the map.

- To re-center maps: Click on the home icon, which appears when you hover in the top left corner.
- To explore each map: Select one of the tabs on top.
- To display relevant tooltip data: Select or hover over individual facilities and census tracts.
- To customize your results: Adjust filter criteria, search by facility name, click on legends or plots.
- Zooming in and out: Use your mouse or the buttons that appear when you hover in the top left corner.
- For details on the data and methodology: Please refer to the Notes below.
1 The database of permitted facilities and reported emissions used in this visualization was compiled using the California Air Resources Board’s (CARB) Facility Search Engine.
2 NOx = oxides of nitrogen (reported as equivalent amounts of NO2); SOx = oxides of sulfur (reported as equivalent amounts of SO2); CO = carbon monoxide; PM = particulate matter; BC = black carbon.
3 Criteria air pollutants are six common air pollutants regulated by the US Environmental Protection Agency (EPA). They are the only air pollutants with national air quality standards that define allowable concentrations in ambient air. The six criteria pollutants are CO, SO2, NO2, PM, ozone (O3) and lead (Pb). Lead is shown here in the Air Toxics tab, as reported in CARB’s facility emissions inventory.
4 TOG = Total Organic Gases. These include all compounds of hydrogen and carbon (with or without other chemical elements), excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate. TOGs are shown here in the Criteria Air Pollutants tab, as reported in CARB’s facility emissions inventory.
5 Air toxics, or toxic air contaminants (TACs), are pollutants that may have serious long-term reproductive, developmental or neurological effects, or may cause cancer. Most air toxics have no known safe levels, and some may accumulate in the body from repeated exposures. BTEX (benzene, toluene, ethylbenzene and xylene) are aromatic hydrocarbons classified as priority pollutants for air monitoring.
6 CalEnviroScreen (CES) is California’s environmental justice cumulative impact methodology that integrates 20 different health, environmental burden and socioeconomic indicators. For the chosen CES indicator, the background layer of the map indicates the percentile rank of each census tract compared to all other census tracts in California.
