The Richest 10% Drive Two-Thirds of Global Warming Since 1990 Due to Consumption and Investment Patterns

The wealthiest 10 per cent of individuals are responsible for two-thirds of global warming experienced since 1990. This significant contribution stems from their consumption and investment behaviours, which have demonstrably amplified the risks associated with extreme climate events like deadly heatwaves and severe droughts. The impact is disproportionately high, with the richest one percent contributing substantially more to such events compared to the global average.
Consumption and Investment Amplify Climate Risks

The consumption and investment patterns of the wealthiest demographic have been identified as key drivers behind the increased incidence and severity of extreme weather events. For instance, the richest one percent of the global population have contributed 26 times more to once-a-century heatwaves and 17 times more to droughts in regions like the Amazon, when compared to the emissions attributable to the average global citizen. These figures highlight a direct correlation between concentrated wealth and heightened climate impacts, moving beyond simple carbon accounting to establish climate accountability.
Emission Burdens from Wealthy Populations in Major Economies

Specific national contexts further illustrate this disparity. In China and the United States, which together represent a substantial portion of global carbon pollution, emissions originating from the wealthiest 10 per cent have each led to a two-to-threefold increase in the frequency and intensity of heat extremes. This concentration of impact underscores how the consumption and investment choices of affluent populations within these major economies significantly exacerbate global warming trends.
The Role of Financial Investments in Climate Change

Beyond personal consumption, the study places significant emphasis on the emissions embedded within the financial investments made by the wealthiest individuals. This suggests that the ownership of capital and the flow of investments into carbon-intensive sectors play a crucial role in driving global warming. The burning of fossil fuels and ongoing deforestation have collectively raised Earth's average surface temperature by 1.3 degrees Celsius, with the majority of this warming occurring within the last 30 years, a period coinciding with significant wealth accumulation and investment by the top income brackets.
