Wealthiest 10% of US Households Responsible for 40% of Greenhouse Gas Emissions: Study
"Without policies such as regulations or taxes on very polluting investments, it's unlikely that wealthy individuals making a lot of money from fossil fuel investments will stop investing in them," says one economist.

The richest tenth of U.S. households are responsible for 40% of all the nation's greenhouse gas emissions, a study published Thursday revealed, underscoring what progressives say is the need for regulations and taxes on carbon-intensive investments.
Published in PLOS Climate, the study—which was led by University of Massachusetts, Amherst sustainability scientist Jared Starr—analyzed 30 years of U.S. household income data and the greenhouse gas emissions generated in creating that income.
"We find significant and growing emissions inequality that cuts across economic and racial lines," the paper notes. "In 2019, fully 40% of total U.S. emissions were associated with income flows to the highest earning 10% of households."
"Among the highest-earning 1% of households (whose income is linked to 15-17% of national emissions), investment holdings account for 38-43% of their emissions," the publication continues. "Even when allowing for a considerable range of investment strategies, passive income accruing to this group is a major factor shaping the U.S. emissions distribution."
"It just seems morally and politically problematic to have one group of people reaping so much benefit from emissions while the poorer groups in society are asked to disproportionately deal with the harms of those emissions."
The study's findings are consistent with research published in 2021 by the Institute for European Environmental Policy and the Stockholm Environment Institute that estimated the wealthiest 1% of humanity was on track to produce 16% of all global CO2 emissions by 2030. Additionally, a 2022 Oxfam report found that a single billionaire produces a million times more carbon emissions than the average person.
Starr told The Washington Post that "as you move up the income ladder, an increasing share of emissions is associated with investments."
According to the Post:
Then there were "super-emitters" with extremely high overall greenhouse gas emissions, corresponding to about the top 0.1% of households. About 15 days of emissions from a super-emitter was equal to a lifetime of emissions for someone in the poorest 10% in America.
The team found that the highest emissions linked to income came from white, non-Hispanic homes, and the lowest came from Black households. Emissions peaked until age 45 to 54, and then declined.
"It just seems morally and politically problematic to have one group of people reaping so much benefit from emissions while the poorer groups in society are asked to disproportionately deal with the harms of those emissions," said Starr.
The study asserts that "results suggest an alternative income or shareholder-based carbon tax, focused on investments, may have equity advantages over traditional consumer-facing cap-and-trade or carbon tax options and be a useful policy tool to encourage decarbonization while raising revenue for climate finance."
Lucas Chancel, a French economist who was not part of the study, told the Post that "all Americans contribute to climate change, but clearly not in the same way."
"Without policies such as regulations or taxes on very polluting investments," he stressed, "it's unlikely that wealthy individuals making a lot of money from fossil fuel investments will stop investing in them."
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
