A new analysis led by researchers at the University of Oxford shows that the annual environmental damage caused by the top 10% of the world's consumer groups is worth between 1.7 trillion and 5.7 trillion US dollars. This amount is several times the total amount of money currently invested in combating climate change and protecting biodiversity. The research was published in the journal "Communications-Sustainability" on June 18, 2026.
The study quantifies the real impact of resource-intensive consumption on the planet by assessing environmental pressures in four key areas: climate change, biodiversity loss, nutrient pollution and freshwater use. Data show that the degree of environmental damage is highly related to consumption power, with biodiversity loss accounting for the largest proportion, reaching 47% to 56%, followed by climate change, accounting for 36% to 45%. This suggests that the climate and biodiversity crises currently facing humanity are so closely linked that they can no longer be viewed as separate policy issues.
The study found that environmental stresses are extremely unevenly distributed geographically. Among the world's top consumer groups, more than 60% of the population live in the United States and the European Union. In the European Union, 40% to 45% of residents belong to this high-consumption class, while in the United States, this proportion is even more than half. From an individual perspective, the average annual environmental damage caused by each member of the top 10% of the world is between US$2,300 and US$7,500. In the United States, this figure is as high as US$19,000 to US$63,000, equivalent to 6% to 20% of their personal income, or 0.8% to 3% of their personal wealth.
The researchers noted that the estimates may still be conservative because the study only covered four of the nine planetary boundaries and focused primarily on direct consumption. For the wealthiest groups, emissions from investment behavior are often equivalent to direct personal consumption, but this analysis has not yet taken into account this indirect impact.
Professor Paul Behrens of the Martin School of Oxford University emphasized that the top 10% of groups are not only the main perpetrators of environmental damage, but also the most influential promoters of reform. Their investment decisions, business management models and lifestyles profoundly shape industry trends and social norms.
Inge Stryver of the Institute of Environmental Sciences at Leiden University, who participated in the study, said that although monetizing environmental damage is morally uncomfortable, this value intuitively reveals the responsibility and remediation potential that this group should bear. If the "polluter pays" principle can be implemented and the environmental taxes collected are used exclusively for sustainable development, it will greatly make up for the current funding gap in global climate and biodiversity protection. The study suggests that levying environmental taxes on luxury consumption rather than basic needs can not only reflect social fairness, but also more effectively curb environmental emissions.
The study concluded that this finding is not intended to treat nature as a commodity, but to make the public aware of the concentration of environmental damage and provide a scientific basis for the development of more stringent preventive environmental rules and policies.
