State and County Emission Summaries
Sources of air pollutant emissions vary from one area to another. State and county summaries grouped by major source sectors(1 pg, 14 K) are available for each of these pollutants:
- Carbon Monoxide
- Lead (Pb)
- Ground-level Ozone Precursor: Nitrogen Oxides (NOx)
- Ground-level Ozone Precursor: Volatile Organic Compounds (VOCs)
- Particulate Matter (PM)
- Sulfur Dioxide (SO2)
Facility Emission Summaries
Facility-level information is available in KML format which can be viewed with Google Earth. The information is also available in text format, CSV or HTML.
The Google Earth emissions files are provided by EPA and are not hosted on a Google Earth server. They contain facility-level information for the top 8 major point-source sections per pollutant. Emissions from nonpoint and mobile sources are not available in Google Earth format at this time.
- Top CO emitting sectors(1 pg, 2 MB)
- Top PM2.5 emitting sectors(1 pg, 2 MB)
- Top NOx emitting sectors(1 pg, 2 MB)
- Top SO2 emitting sectors(1 pg, 1 MB)
- Top PM10 emitting sectors(1 pg, 2 MB)
- Top VOC emitting sectors(1 pg, 3 MB)
One important feature of these files is that you can toggle on and offExit the sectors that are displayed on the map. So if you want to focus only on Electricity Generation via Combustion, you can turn the other sectors off so they don't appear on the map.
Another important feature of these files is that you can tiltExit the display. Since the height of each point corresponds to the total emissions from the facility, you can identify "big" emitters quickly and easily.
Note that some facility coordinates may be based on a different projection system than Google Earth's, resulting in a slight visual shift (less than a mile) from the actual location.
Users new to Google Earth will notice that there are "layers" of information provided in the Google Earth software that are independent of this emissions files. They provide the ability to overlay additional geographic information like roads, topography, and landmarks. Some of these layers may already be turned on when you open Google Earth.
Create a File by State or Source Type
Want to focus on a particular state or source type? You can create your own files that are specific to certain states or source types. Just follow these steps.
