U.S. Coal Producers and Greenhouse Gas Emissions, 2020

PERI is extending its long-standing Greenhouse 100 project by adding information on suppliers of fossil fuels and how much CO2 is released when their fuel is burned. As a first step, PERI has assembled data on US coal mine production for the year 2020 along with the ultimate parent companies that own each coal mine as of May 2022.

The complete dataset and documentation are available at:


Coal production and estimated CO2 emissions for the top 30 parent companies in the database are listed in the table below.
