On September 15, the White House Office of Management and Budget approved proposed guidance from the Environmental Protection Agency for eight broad industrial sources (including electronics manufacturers) concerning whether greenhouse gas emissions data reported to the government will be considered confidential. The rule will cover sources that that emit 25,000 metric tons of carbon dioxide-equivalent or more a year, with the proposed rule to be published in the Federal Register soon and finalized in March 2012. In addition to electronics manufacturers, electric bulk power transmission, crude petroleum and natural gas extraction, and manufacturing of commercial and industrial refrigeration equipment, will also be covered. EPA's mandatory greenhouse gas emissions requirements cover 41 industrial categories and between 85%-90% of total GHG emissions, with 29 of those sectors required to report 2010 emissions this year and the remaining 12 sectors to report 2011 emissions next years.
