GHGRP 2011: Metals
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 stationary fuel combustion sources. All other metal production facilities report only the GHG emissions from stationary fuel combustion sources.
- Total Reported Direct Emissions from Metals Production, by Subsector (as of 1/16/13).
- Location and emissions range for each reporting facility in the metals sector (as of 1/16/13).
This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility.

Process emissions from magnesium production were reported in 2011 but not in 2010. These emissions are included in the table above. Total emissions from this source category in 2011 were 2.5 MMT CO2e.
CO2 emissions from the combustion of biomass are NOT included in emissions totals provided above.
