Top 10% cause $5.7tn yearly eco-damage
18 Jun
Summary
- Top 10% consume $5.7tn annually in environmental damage.
- Red meat and energy consumption drive most damage.
- Targeting wealthy consumers with taxes could fund sustainability.
The highest-consuming 10% of the global population incurs an annual environmental damage bill of up to $5.7tn, a figure surpassing the economies of all countries except the United States and China. This group, largely concentrated in the global North, drives significant damage through consumption patterns, particularly red meat linked to deforestation and energy use from fossil fuels for heating and flights. Biodiversity loss accounts for over half of this damage, with the climate crisis responsible for a substantial portion.
The monetary impact of this consumption, calculated by researchers at the University of Oxford and University of Leiden, highlights a mismatch with global funding needs for environmental crises. Average annual damage per person in the top 10% ranges from $2,300 to $7,500, escalating to $19,000-$63,000 for individuals in the US. High-consuming households in emerging economies are also contributing significantly, with China's top 10% now exceeding Germany's in environmental damage.
Studies indicate that the true environmental cost, including the impact of investments, is likely even higher. The findings strengthen the argument for addressing climate and biodiversity crises concurrently. To mitigate this, governments are advised to consider taxes on luxury goods, wealth, and carbon. Applying polluter-pays principles to these high-consuming groups could generate substantial revenue for sustainability transitions and reduce existing inequalities. The top 10% possess significant leverage, not only as consumers but also as investors and influencers, to drive emission reductions.
