Top 10 Corporations Responsible for 44% of U.S. Greenhouse Gas Emissions (2026)

Unveiling the Hidden Culprits: 10 Corporations Behind 44% of US Greenhouse Gas Emissions

Are we overlooking the key players in the fight against climate change?

Did you know that just 10 corporations are responsible for a staggering 44% of greenhouse gas emissions in the United States? This revelation comes from a groundbreaking study by the University of Massachusetts Amherst Political Economy Research Institute (PERI), which has shed light on the fossil fuel suppliers contributing the most to global warming.

The Greenhouse 100 Suppliers Index, a new tool from PERI, ranks the top corporate contributors to greenhouse gas emissions from fossil fuel supplies. The top four suppliers, Marathon Petroleum, Phillips 66, Exxon Mobil, and Valero Energy, collectively produced over 250 million metric tons of carbon dioxide-equivalent emissions. But it's not just these four; the next two companies, Core Natural Resources and Peabody Energy, are also major players due to their coal mining operations.

The index reports 2023 greenhouse gas emissions resulting from oil, natural gas (methane), and coal supplies, using the latest data available from the Environmental Protection Agency’s Greenhouse Gas Reporting Program. However, the EPA has announced its intention to end most of the program and suspend remaining reporting requirements until 2034, raising concerns about the loss of vital public information.

Professor Michael Ash, co-director of PERI’s Corporate Toxics Information Project, emphasizes the importance of the Greenhouse 100 Index, stating, "The EPA decision to effectively end the Greenhouse Gas Reporting Program removes access to vital public information and leaves public and private decision-makers flying in the dark or relying on a patchwork of voluntary and potentially cherry-picked or greenwashed reports."

The Greenhouse 100 Index offers a free, open-access online search tool that includes all 778 companies reporting to the EPA’s Greenhouse Gas Reporting Program, including privately held companies like Koch Industries, which ranks No. 11 on the Suppliers Index with over 100 million metric tons of CO2-equivalent releases. The tool also features state rankings and reports detailing the companies and facilities responsible for each state’s fossil fuel supply, with Texas, Louisiana, Wyoming, California, and Illinois ranking highest.

"In making this information available, we are building on the historic achievements of the right-to-know movement," Ash said. "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."

But here's where it gets controversial... The study's findings raise important questions about the role of these corporations in the climate crisis. Are we doing enough to hold them accountable? And this is the part most people miss... The Greenhouse 100 Index is not just about exposing the culprits; it's about empowering the public to take action. So, what do you think? Do you agree with the findings? Or do you have a different perspective? Share your thoughts in the comments below!
