A New Study Prices The Environmental Damage Of The Top 10%. For A Wealthy American It Could Be $63,000 A Year
A new study prices the environmental damage of the world's richest 10% at up to $5.7 trillion a year, and finds biodiversity loss, not carbon, is the biggest share.

Key Takeaways
The world's richest 10% cause $5.7 trillion in environmental damage annually, according to a new study in Nature Sustainability.
For a wealthy American in the top 10%, the annual environmental damage amounts to $63,000 per person.
Biodiversity loss (62% of total) outweighs carbon emissions as the largest cost driver for high-income individuals.
The study uses consumption-based accounting, tracking impacts across supply chains from energy use to land conversion.
The bottom 50% of global earners contribute only 2% of environmental damage, highlighting extreme inequality in ecological footprints.
A wealthy American causes $63,000 in environmental damage every single year — and the largest chunk isn’t from carbon emissions. A new study from researchers at the University of California, Berkeley and the London School of Economics has quantified the environmental toll of the world’s richest 10%, putting the annual price tag at $5.7 trillion. For a typical wealthy American, that works out to $63,000 per year, with biodiversity loss driving the majority of the cost. The study, published in Nature Sustainability, uses consumption-based accounting to track the full supply chain impact of goods and services consumed by different income groups. It finds that the top 10% of earners globally are responsible for 45% of all environmental damage, while the bottom 50% contribute just 2%. Biodiversity loss — from land use, water extraction, and pollution — accounts for 62% of the damage, far exceeding the carbon footprint share. The authors calculate that if the wealthiest individuals paid for the environmental damage they cause, the average annual cost would be $63,000 for a U.S. resident in the top 10%, $38,000 for a European counterpart, and just $500 for someone in the bottom 10%. The study’s lead author, Dr. Emma Greenfield, said the findings challenge the common assumption that carbon emissions are the most important environmental metric. “We’ve underestimated the role of biodiversity loss and land-use change. For the rich, these damages are even larger than their climate impact.” The research comes as governments debate wealth taxes and environmental subsidies. Critics argue that pricing damage is subjective, but supporters say it provides a clear target for progressive climate policy. The next step is to model how a “polluter-pays” fee for the wealthy could fund conservation and clean energy transitions. With climate negotiations set to resume in November, the study adds new urgency to questions about who should bear the environmental cost. The environmental damage of the rich is now quantified — and the bill is staggering.
Frequently Asked Questions
According to a new study published in Nature Sustainability, the world's richest 10% cause an estimated $5.7 trillion in environmental damage each year. This includes biodiversity loss, carbon emissions, and other impacts from their consumption patterns.
Biodiversity loss accounts for 62% of the environmental damage caused by the top 10% of earners. This includes land-use change, water extraction, and pollution, which outweigh carbon emissions as the largest cost driver.
The study uses consumption-based accounting, which tracks the full environmental impact of goods and services consumed by individuals, including supply chains. For a wealthy American in the top 10%, the annual damage is $63,000 per person.
Policymakers could implement a 'polluter-pays' fee or environmental surcharge on high-income individuals, with funds directed toward conservation and clean energy. The study provides a framework for pricing damage and targeting progressive climate policy.
The study focuses on consumption-based impacts, meaning it accounts for the environmental damage embedded in goods and services purchased by individuals. It does not separately quantify damage from financial investments or shareholder activities.
