Environmental Damage Costs of the World’s Top-10% Consumers: A Monetary Assessment

The study estimates the top 10 % of consumers cause $1.7–$5.7 trillion of environmental damage (2017 US $). Per-person damage is $2,300–$7,500; in US it reaches $19,000–$63,000 (6–20 % of income, 0.8–3 % of wealth). Biodiversity loss accounts for 47–56 % of the total, climate change 36–45 %, nitrogen 6–8 %, and water and phosphorus under 2 %.

Top 10% Cause $5.7T in Environmental Damage Yearly

The authors combined consumption-based footprints for the top decile with values from the Environmental Prices Handbook 2024, covering climate, biodiversity (mean species abundance loss), nutrient pollution and freshwater use. Prices were scaled by GDP per capita (CO2 priced uniformly). Footprint data are from 2017, the year with comparable consumption metrics.

Top 10% Cause $5.7T in Environmental Damage Yearly

Over 60 % of the top-10% cohort lives in the United States or the European Union; more than half of Americans belong to it. The U.S. per-person bill reaches $19,000–$63,000. Germany and China follow; India and Egypt show lowest bills at $410–$1,400 (0.8–2.8 % of income, 0.2–0.5 % of wealth). About half of emissions from high-income individuals stem from investments, which the analysis excludes.

Authors note damage bill could cover the $993 billion annual climate-financing gap and the $675 billion biodiversity-funding shortfall by 2030. They propose progressive environmental taxes on luxury consumption or wealth in low-income contexts and note revenue redistribution could reduce inequality while cutting emissions. They caution taxation alone will not solve the crises but can fund mitigation and adaptation.

Biodiversity valuation uses European ecosystem prices, creating uncertainty for regions such as Brazil, India or Egypt. The analysis omits five planetary boundaries—novel entities, land-system change, ocean acidification, atmospheric aerosol loading, and stratospheric ozone depletion—likely underestimating damage. Reliance on 2017 consumption data may miss recent trends, and investment-linked emissions remain unaccounted.

• “If anything, these numbers are conservative. The bill leaves out the emissions tied to wealthy people’s investments,” — Paul Behrens, British Academy Global Professor, Oxford Martin School, University of Oxford

• “Behrens said: “The top 10% are important not only because they cause the most damage but also because they hold the most leverage to reduce it.” — Paul Behrens, University of Oxford

• “ Lead author, Inge Schrijver, Institute of Environmental Sciences, Leiden University, Netherlands: "While I find it uncomfortable to put a price on the environment, as nature's true value is infinite, showing total damage in money terms does show the size of both the damages and responsibility of the top 10%.” — Inge Schrijver, Institute of Environmental Sciences, Leiden University

• “The scale of the damage bill illustrates the potential revenue if polluter-pays principles were applied to high-consuming groups,” — Study authors, *Communications Sustainability*

The Guardian

The researchers call for expanded accounting that adds missing planetary boundaries and investment-related emissions, and for dialogues on progressive environmental and wealth taxes to channel estimated revenue toward UN climate and biodiversity financing targets.
