Published in Communications Sustainability, the analysis places a monetary value on damage across four major planetary boundaries: climate change, biodiversity loss, nutrient pollution, and freshwater use.
The findings offer a stark measure of how heavily environmental
pressures are concentrated among the world’s most resource-intensive consumers.
Rich consumption drives damage
For each person in the global top 10%, the average annual
damage cost ranges from $2,300 to $7,500. In the United States, where
per-person impacts are the highest, the figure climbs to $19,000 to $63,000.
That is equal to 6 to 20% of income, or 0.8 to 3% of wealth.
The geography of high consumption is concentrated. More than
60% of the global top 10% live in the United States and the European Union. In
the EU, 40 to 45% of people fall into this highest-consuming group. In the
United States, more than half of the population does.
Biodiversity loss makes up the largest share of the global
damage bill, accounting for 47 to 56% of the total. Climate change follows at
36 to 45%. The pattern strengthens calls for biodiversity loss and climate
change to be treated as connected crises, rather than separate policy problems.
The numbers are probably conservative. The study covers only
four of the nine planetary boundaries and focuses on direct consumption. For
the wealthiest individuals, about half of emissions come from investments
rather than personal consumption, and those investment-related impacts were not
included in the analysis.
Polluter pays enters focus
The size of the damage estimate shows how much revenue could
be raised if polluter pays principles were applied to high-consuming groups.
The researchers note that environmental taxes aimed at luxury consumption,
rather than basic goods, tend to be more progressive and more effective at
cutting emissions. They also stress that pricing is only one tool and does not
undo or fully compensate for the damage itself.
Paul Behrens, British Academy Global Professor at the Oxford
Martin School, University of Oxford, and co-author of the study:
“The top 10% are important not only because they cause the
most damage but also because they hold the most leverage to reduce it. The
capital they invest, from pensions to infrastructure, decides which industries
expand, the firms they run set the choices for everyone else, and the
lifestyles they pursue shape what people consider as normal. They often have
outsized agency, not only individually as consumers, but also as investors,
employers, trend makers, and market shapers. Their power to cut emissions is
even larger than their share of them.”
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
monetary terms does show the size of both the damages and responsibility of the
top 10%. The damage bill is higher than the money needed internationally for
climate and biodiversity funds. If the polluter pays and that money goes to
solutions, it would make a huge difference. But it is not just about money.
Most importantly, damage must be prevented. Apart from financial measures, stricter
rules and regulations are crucial.”
Monetary costs reveal scale
The study combines consumption-based environmental
footprints with prices from the Environmental Prices Handbook 2024 to estimate
monetary damage across climate change (CO₂), biodiversity loss
(mean species abundance loss), nitrogen and phosphorus pollution, and
freshwater use. The researchers scaled prices across countries using GDP per
capita. The consumption data came from 2017, the latest year with globally
comparable footprint data.
The differences between countries reflect major inequalities
in consumption. Among the countries studied, the United States had the highest
per-person damage bill, while India and Egypt had the lowest. The analysis
covered six countries (Brazil, China, Egypt, Germany, India, USA) as well as
global totals.
The authors emphasize that putting a monetary value on
environmental damage is not the same as treating nature as a commodity. Money
can capture only part of what ecosystems are worth. In this study, the goal is
to make the scale of concentrated environmental harm more visible and to show
how much revenue could be generated if the polluter pays principle were put
into practice.
