How to Download Your Data
Note: Processing National Emissions Inventory data will require use of data processing software. The
data are available
in a tab or comma-delimited text format that must be imported into a program that will allow you to
analyze the file.
- For 1996, 1999, 2002, and 2005, use the following links:
- For 2008, 2011, 2014, and 2017, use the following links:
At each link, click the “Data Summaries” tab, then download the file “Facility-level by Pollutant.”
- Coal mining facilities are grouped under NAICS codes beginning with 2121 for the years 2002 – 2017.
To identify the
SIC codes corresponding to NAICS 2121 for the 1996 and 1999 datasets, use the following crosswalk:
https://www.naics.com/sic-naics-crosswalk-search-results/
- Using the SIC and NAICS codes, filter for paper products facilities, then sum total emissions of CO,
NOX, VOC, PM10,
NH3, and SO2 in each year to arrive at the totals shown in this chart.
