The top 10% of consumers cause environmental damage exceeding climate and biodiversity financing needs
The wealthiest 10% of consumers in the world are responsible for a disproportionate share of the damage inflicted on the planet. Their activities incur colossal environmental costs, often borne by society as a whole. A recent analysis reveals that these consumers generate annual environmental damage estimated between $1.7 trillion and $5.7 trillion, or between $2,300 and $7,500 per person. These amounts far exceed the current financing needs to combat climate change and biodiversity loss on a global scale.
In the United States, the top 10% see their environmental bill reach between $19,000 and $63,000 per year. This represents between 6% and 20% of their income, or between 0.8% and 3% of their wealth. In contrast, in India, this bill is much lower, ranging between $410 and $1,400, or 0.8% to 2.8% of their income or 0.2% to 0.5% of their wealth. These disparities reflect inequalities in consumption and emissions between countries.
Biodiversity loss and climate change are the two main contributors to this environmental bill. Globally, ecosystem destruction accounts for between 47% and 56% of the total, while climate accounts for 36% to 45%. Next come damages related to nitrogen, freshwater, and phosphorus, but their share remains much lower.
The damage caused by the top 10% is so significant that it alone exceeds the financing needs for biodiversity and climate. For example, the low estimates for the United States and China already cover the $675 billion deficit needed for biodiversity by 2030. The central estimate for the United States even exceeds the $993 billion annually required for climate action by 2035. Thus, the potential revenue from an environmental tax targeting this group could fund the necessary transitions.
Biodiversity loss, measured here by the decrease in the average abundance of species in an ecosystem compared to its natural state, is a major issue. Its monetary evaluation remains complex, as it depends on the type of ecosystem, its condition, and its location. The prices used for this study are based on European values, adjusted according to GDP per capita for each country. However, this method does not account for all local factors, such as population density or species rarity, which could underestimate or overestimate the actual costs.
The idea of monetizing environmental damage sparks debate. Some see it as a useful tool for raising awareness, improving incentives, and generating funds for sustainable practices. Others criticize this approach, arguing that it reflects existing inequalities and reduces nature to a mere economic value, ignoring its irreplaceable character. However, this study does not seek to justify the commodification of nature, but rather to highlight the increased responsibility of the top 10%.
An environmental tax targeting this group could not only reduce emissions but also improve equity. In low-income countries, a carbon tax is generally progressive, whereas in wealthy countries, a uniform tax can be regressive if revenues are not redistributed. By targeting luxury goods rather than essential products, it is possible to make this taxation fairer and more effective. Additionally, if revenues are used to fund green investments or redistributed to low-income households, public acceptance increases.
The top 10% of consumers therefore have a key role to play in the ecological transition. Their responsibility is all the greater as they are also investors, citizens, and role models for others. A targeted mitigation policy for this group could thus reduce emissions, generate revenue for the transition, and improve equity simultaneously.
