PERI Releases Comprehensive Greenhouse Gas Rankings of U.S. Fossil Fuel Suppliers

AMHERST, MA, October 2, 2023 – The Political Economy Research Institute (PERI) of the University of Massachusetts Amherst announces the publication of the Greenhouse 100 Suppliers, a comprehensive ranking of corporations that contribute to U.S. greenhouse gas emissions (GHG) by supplying fossil fuels. The Greenhouse 100 Suppliers rankings come with an open-access database that provides information on all fossil fuel suppliers in the country and by state, both at the level of individual facilities and at the level of parent corporations that own them, and offers a comprehensive search tool for every fossil fuel corporation.

The following is PERI's analysis for California.

The recent court case Held vs Montana, a historic victory for young climate advocates, drew attention to the importance of fossil fuel production at the state level. The companion Greenhouse 100 Suppliers State List presents state rankings for the quantity of fossil fuels introduced into the U.S. economy. Texas, Wyoming, Louisiana, California, and Illinois top the list. (Montana is 14th among states.)

The Greenhouse 100 Suppliers rankings are the first comprehensive database to cover emissions from all three fossil fuels: oil, natural gas, and coal. The Greenhouse 100 Suppliers rankings are based on data from the U.S. Environmental Protection Agency’s Greenhouse Gas Reporting Project (GHGRP) on oil and natural gas suppliers, together with data on coal suppliers obtained from the U.S. Energy Information Administration and the Mine Safety and Health Administration, using methods described in a peer-reviewed journal article. (Coal suppliers were exempted from the reporting requirements of the GHGRP.) This second edition of the Greenhouse 100 Suppliers contains more detailed data than the first edition, especially for coal mines, and the Greenhouse 100 Coal Suppliers data are also available.

The rankings provide a window on corporate responsibility for greenhouse gas emissions and potential liability for the resulting damages to Earth’s climate. “In making this information available, we are building on the historic achievements of the right-to-know movement,” explains Professor Michael Ash, co-director of PERI’s Corporate Toxics Information Project. “Our goal is to engender public participation in environmental decision-making, and to help residents translate the right to know into the right to clean air, clean water, and a livable planet.”
