Greenhouse Gas Reporting Program
The metals sector consists of metal production facilities that smelt, refine, and/or cast ferrous and nonferrous metals, including primary aluminum, ferroalloy, iron and steel, lead, magnesium, and zinc, from ore, pig, or scrap using electrometallurgical and other methods. The sector also includes foundries and any other metal production facility operating under NAICS codes beginning with 331 (Primary Metal Manufacturing). Primary aluminum, ferroalloy, iron and steel, lead, magnesium, and zinc production facilities report GHG emissions from metal smelting, refining, and/or casting activities, as well as from stationary fuel combustion sources. All other metal production facilities report only the GHG emissions from stationary fuel combustion sources. Data for magnesium production were reported beginning in 2011 while data for all other metal production were reported beginning in 2010.
- 2012 Total Reported Direct Emissions from Metals, by Subsector (as of 9/1/13).
- Trend of Annual Reported GHG Emissions by Subsector (as of 9/1/13).
- Location and emissions range for each reporting facility in the metals sector in 2012 (as of 9/1/13).
This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility.

Totals may not equal sum of individual GHGs due to independent rounding.
NR means that this value was not reported for the 2010 reporting year.
** Total reported emissions are less than 0.05 million metric tons CO2e.
Process emissions from magnesium production (sulfur hexafluoride) were reported beginning in 2011. These emissions are included in the table above. Total emissions from magnesium production were 1.9 MMT CO2e in 2011.
CO2 emissions from the combustion of biomass are NOT included in emissions totals provided above.
