Explanatory notes (For details, see the technical notes).
* Percentages are the parent corporation or entity's percentage of all U.S. greenhouse gas emissions, including electric power, transportation, industrial, commercial, residential, and agricultural emissions, the total of which is 6,673 million metric tons of CO2 equivalents according to the April 2015 U.S. Inventory of Greenhouse Gas Emissions and Sinks. Note that this total is for 2013 while Greenhouse 100 parent and facility emissions are for 2014.
The links from each parent name lead to an application that gives detailed facility and sector information about the company. You can also search for companies not on the Greenhouse 100. For more information on the data, see the technical notes.
