GHGRP 2016: 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 from stationary fuel combustion sources. All other metal production facilities report only the GHG emissions from stationary fuel combustion sources.
- 2016 Total Reported Direct Emissions from Metals, by Subsector (as of 8/5/17).
Sum of percentages may not equal 100% due to independent rounding.
- Trend of Annual Reported GHG Emissions by Subsector (as of 8/5/17).
What factors influenced the trend in emissions for metals production?
- Location and emissions range for each reporting facility in the metals sector in 2016 (as of 8/5/17).
This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility.
