Greenhouse Gas Reporting Program


Under the Greenhouse Gas Reporting Program facilities can re-submit GHG reports for past years at any time. All values and graphics presented here were last updated on April 6, 2012. To review the most recent 2010 data reported by each facility, see the Data Highlights page for the most recent year, download summary GHG data, explore FLIGHT, or download facility-specific data through Envirofacts.

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.
