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.”
- Chemical manufacturing facilities are grouped under SIC codes 2812, 2813, 2816, 2819, 2821-24,
2833-36, 2841-44,
2851, 2861, 2865, 2869, 2873, 2875, 2879, 2891-93, 2895, 2899, 2923, 2974, and 3087 for the years
1996 and 1999 and
NAICS codes beginning with 325 for the years 2002 – 2017.
- Using the SIC and NAICS variables, filter for chemical 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.

Greenhouse Gases
How to Download Your Data
- Go to https://www.epa.gov/ghgreporting/ghg-reporting-program-data-sets
- Click the “2018 Data Summary Spreadsheets” link. In the resulting ZIP file, open the spreadsheet,
“ghgp_data_by_year.xlsx.” Navigate to the first worksheet, “Direct Emitters.”
- Apply a filter to Column K (Primary NAICS Code), displaying only the values for NAICS Codes
beginning with 325.
- With the filter from Step 3 applied, for each year, 2011 through 2018, sum the relevant column of
“Total reported direct emissions.” For example, Column T corresponds to 2011, Column S corresponds
to 2012, etc.
- For 2010 data, open the spreadsheet, “ghgp_data_2010” from the ZIP file. Repeat Steps 3
and 4 in this file; the 2010 “Total reported direct emissions” data are in Column N of the “Direct
Emitters” worksheet.

Employment
How to Download Your Data
Note: Processing employment data from the Census Bureau will require use of data processing software.
The data are available in a comma-delimited text format that must be imported into a software
package that will allow you to analyze the file.
- Go to https://www.census.gov/programs-surveys/cbp/data/datasets.html
- Click on any link labeled “County Business Patterns: YEAR.” On the resulting page, click the
“Complete U.S. File” link and download the corresponding file. Repeat this process for each year
from 1998 to 2018.
- Open each file in a software package of your choice that can process comma-delimited text files.
Repeat the steps below for each file.
- For entities with suppressed data, the Census Bureau replaces all employment values with zeroes and
this underestimates the total number of employees in each sector. Using your software package,
replace the suppression flags with the midpoint of the Data Suppression Flag employment ranges per
the table below.
