The metals sector consists of 269 metal production facilities that smelt and/or refine ferrous and nonferrous metals from ore, pig or scrap, using electrometallurgical and other methods, including primary aluminum, ferroalloy, iron and steel, lead, zinc, and any other metal production facility operating under NAICS codes beginning with 331. Primary aluminum, ferroalloy, iron and steel, lead, and zinc facilities report GHG emissions from metal smelting and/or refining activities, as well as stationary fuel combustion sources. All other metal production facilities report only the GHG emissions from stationary fuel combustion sources. Approximately 4% of facilities in this sector measure emissions using continuous emissions monitoring equipment. The majority of facilities use engineering calculations based on measured data.

  This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility.

Metals Sector 2010 Greenhouse Gas Emissions Reported to the GHGRP

• Number of facilities: 269
• Total emissions (CO2e): 99.8 million metric tons
• Emissions by category (CO2e):

   

  Combustion sources: Combustion emissions are produced from the combustion of fuel to provide process heat for industrial, commercial, or institutional use, whether the combustion is internal or external to the manufacturing process equipment. Examples are boilers, stationary internal combustion engines, process heaters, kilns, combustion turbines, and waste incinertors.

  Process emission sources: Process emissions are vented, evaporative, or fugitive emission from industrial manufacturing processes and from decomposition processes at landfills and wastewater treatment systems.

  • Combustion: 64.8 million metric tons
  • Process: 35.0 million metric tons

CO2 emissions from the combustion of biomass are NOT included in emissions totals provided above.
