Explanatory notes (For details, see the technical notes )
This edition of the Greenhouse 100 Suppliers ranks companies by C02-equivalent greenhouse gas emissions from their supply of products in 2022 that result in GHG emissions when the products are released, combusted, or oxidized. This differs from the Greenhouse 100 Polluters because the Greenhouse 100 Polluters ranks companies by direct emissions of GHGs from large facilities. It includes both data from EPA's GHGRP Suppliers database and a PERI database of coal mines based on EIA and MSHA data. Petroleum exports are not included as supplier amounts (we assume that they were also reported as production if they were produced in the US.)
Important: EPA treats some quantities of CO2 released from suppliers as confidential where the supplying facility makes only one product and its amount of production could be calculated from its CO2 emissions. PERI has no way to determine the values of these confidential amounts and has treated them as zeroes. Users of this list should be aware that data derived from EPA's GHGRP Suppliers database are a lower bound and may actually be larger than shown.
The links from each parent name or state lead to an application that gives detailed facility information. You can also search for companies not on the Greenhouse 100 Suppliers Index . For more information on the data, see the technical notes .
