PERI's Greenhouse 100 index identifies the top companies responsible for greenhouse gas emissions.

Explanatory notes (For details, see the technical notes.

This edition of the Greenhouse 100 ranks companies by C02-equivalent greenhouse gas emissions (including CO2, methane, nitrous oxide, and fluorinated gases, but not biogenic CO2) directly released by large facilities in the US in 2022.

Percentage of 2022 U.S. greenhouse gas emissions from all sources: 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 6,343 million metric tons of CO2 equivalents according to the 2022 U.S. Inventory of Greenhouse Gas Emissions and Sinks.  Source: US EPA.

Environmental Justice (EJ): Poor Share and Minority Share: Shares of the potential co-pollutants of combustion borne by people living below the poverty line or by people in minority racial/ethnic groups. In the U.S. population, 10.5 percent lived below the poverty line in 2020 and 40 percent are members of minority racial/ethnic groups.
