The world’s richest 1%—just 8 million people who make, on average, $442,000 a year—produce far more emissions than the poorest 3.5 billion, states the report. Someone in the richest 0.1% emits 48 times more CO2 than the average person in the U.S. over the course of a year. Oxfam used climate attribution models and a consumption-based emissions dataset developed by the Stockholm Environment Institute to calculate emissions by income group. Keeping emissions in check is a key part of addressing the climate crisis. This month, the United Nations warned that, in order to keep warming below 2°C, urgent action must be taken to drastically reduce global emissions by 18% by 2030.Research has long shown that wealthier countries drive a disproportionate share of global emissions. But emissions disparities exist within countries as well. The U.S., for example, is the second largest carbon emitter behind China—but not everyone is responsible for the same share of emissions. The report finds that, in just under four months (118.3 days), someone in the richest 0.1% living in the U.S., those making an average of $1.98 million a year, emits more CO2 than what someone in the poorest half of the country (those making an average of $25,600 a year), has emitted over the last 30 years. One of the biggest sources of emissions? Private jets—which, in 2025, were responsible for 16 million metric tons of CO2, the emissions equivalent of the annual energy use of over 2 million homes. The U.S. has the highest concentration of private jet use—with the majority of all private jets (68%) taking off from the U.S. Combined, all of the world’s private jets emit more in 2 seconds than someone in the world’s poorest 50%, those annually making an average of $1,500, would emit in a year. According to the report, last year private jets spent more than 6.5 million hours in the air. “We see that the ultrarich consume differently than everyday people,” says Carle, who adds that the ultrarich are also far more likely to invest in polluting companies. A list of 217 companies that “profit from either creating climate disasters, preparing for them, or recovering from them,” analyzed in the report shows they made $1.8 billion on average in 2025, and paid out more than $1 billion to shareholders.This has a direct impact on the climate, the report finds. The researchers constructed emissions pathway models to attribute the emissions of different income groups, and found that the richest 1% are responsible for 20% of global warming since 1990—20 times more than their share of the world’s population. Someone from the richest 1% contributed 34 times more than the average person to extreme heat events, the report states, and one year's worth of emissions from the richest 1% will cause an estimated 1.9 million excess heat deaths. Yet, the ultrawealthy are less likely to face the impacts of their emissions. Those with lower incomes are significantly more likely to suffer from the impacts of climate disasters and extreme weather events—and often lack the funds to recover from disasters. Wealthy individuals, on the other hand, are more likely to live in safer locations or have the funds to ride out a disaster—purchasing private resources, like firefighters and generators, or paying a premium for emergency shelter. The authors suggest taxing the emissions of the super-rich. This could be done through taxes on high-emitting luxury items and activities, like private jet use, to disincentivize their use, suggests the report, or via windfall taxes on profits from fossil fuel companies. The report envisions that these taxes could be used to help level the playing field when it comes to climate adaptation, like increasing climate financing in the Global South, or investing in adaptation measures around the world.“We hope that people take away that there are a lot of opportunities to address inequality in ways that protect the planet and protect communities,” says Carle. “Polluters need to pay for the harm that they’ve caused.”
