A new study conducted by Leiden University in the Netherlands has revealed the economic scale of environmental damage caused by the world's top 10% of consumers.
Operative Information Center-OMM reports, citing international media, that the findings highlight significant disparities in ecological footprints.
According to researchers, the annual societal cost of environmental damage resulting from the activities of this wealthy demographic ranges between $1.7 trillion and $5.7 trillion.
Environmental researchers Inge Schrijver, Rutger Hoekstra, and Paul Behrens conducted the large-scale study to quantify environmental harm in economic terms. The analysis examined the consumption footprints of the world's wealthiest 10%, including carbon emissions, impacts on biodiversity loss, water consumption, and nitrogen and phosphorus waste.
The study results indicate that the annual ecological debt for each individual in this group ranges from $2,300 to $7,500. Scientists suggest that this amount could significantly address the massive budget shortfalls in global climate and biodiversity protection programs.
Data shows that the largest portion of total environmental damage—47% to 56%—is linked to biodiversity loss, followed by the impacts of climate change at 36% to 45%.
The research also revealed significant disparities between countries. For instance, in the United States, where luxury consumption is at its highest, the per capita ecological debt of the top 10% is estimated between $19,000 and $63,000. This figure represents approximately 6% to 20% of their annual income and less than 3% of their total wealth. In comparison, the per capita ecological debt of the top 10% in India ranges from $410 to $1,400.
The authors emphasize that a tax system based on the "polluter pays" principle cannot solve global environmental problems alone. However, such a mechanism could create a vital financial source for transitioning to more sustainable consumption models. According to the study, even relatively low environmental taxes applied to the wealthiest strata in the United States and China could bridge the hundreds of billions of dollars in funding gaps for biodiversity protection by 2030.
This research underscores the growing global discourse on climate justice and the responsibility of high-income nations and individuals in mitigating climate change, a topic frequently discussed at international climate summits.
