Two-Thirds of Global Warming Tied to the World’s Richest Ten Percent

Share

Two-thirds of the planet’s warming since 1990 has been traced to the world’s wealthiest ten percent, raising new questions about the material impact of affluence.

Climate change is no longer a diffuse global phenomenon. It has coordinates. The Amazon. Southeast Asia. Southern Africa. And according to a new study, it also has fingerprints: those of the world’s wealthiest ten percent, whose emissions have disproportionately driven the most severe heat and drought events of the past three decades, according to a sweeping new study published in the journal Nature Climate Change.

The study finds that since 1990, record temperatures scorching southern Africa, the receding tree lines of the Amazon, the one-in-100-year heat events that now arrive once a decade have all been materially shaped by a narrow band of global elites. Not necessarily out of malice, but perhaps out of habit.

“Our study shows that extreme climate impacts are not just the result of abstract global emissions,” Sarah Schöngart, lead author and ETH Zurich researcher, said in a statement. “Instead we can directly link them to our lifestyle and investment choices, which in turn are linked to wealth.” According to Schöngart, wealthy emitters play “a major role” in driving climate extremes, which provides strong support for climate policies that target the reduction of their emissions.

That lifestyle, as it happens, has never looked more gilded. According to Bain & Company, global luxury spending is expected to grow from €1.5 trillion now to an estimated €2 trillion to €2.5 trillion by 2030, with the strongest gains in experiential luxury — ultra-private safaris, $200,000 Arctic expeditions, jet-set hotel buyouts. Many of these experiences are carbon-intensive, and, according to the study’s authors, emissions from the wealthiest ten percent in the United States and China alone led to a two-to threefold increase in heat extremes across vulnerable regions.

The numbers are stark. The top one percent of earners globally contributed 26 times the average to extreme monthly heat events and 17 times more to Amazonian drought. The emissions analyzed were not just from consumption, but from investments — a point Schöngart’s coauthor Carl-Friedrich Schleussner made plainly: “Climate action that doesn’t address the outsize responsibilities of the wealthiest members of society risks missing one of the most powerful levers we have to reduce future harm.”

There is no single villain here. There is, instead, a global structure in which financial portfolios have carbon footprints, and the quest for return on investment extends its shadow well beyond quarterly reports. Private equity investments in fossil infrastructure, sprawling real estate developments, and luxury goods manufacturing all funnel emissions upward. The question is not whether the affluent pollute more, but whether their cumulative lifestyle, financial decisions, and travel patterns shape the very climate that others must endure.

As the researchers explain, if the bottom 50 percent of the world’s population had set the global standard, minimal additional warming would have occurred since 1990. But the baseline was never set from the bottom.

And that ambition is shifting. While traditional luxury categories such as couture and watches have slowed, ultra-high-end travel is rising. In 2024, global tourism rebounded to pre-pandemic levels with more than 1.4 billion travelers — an 11 percent increase from the prior year, according to the United Nations World Tourism Organization. A growing share of that movement includes private aviation, hyper-personalized itineraries, and bookings that reach well into six figures. The Royal Mansion in Dubai rents at $100,000 per night. A bespoke Antarctic expedition, outfitted with sommeliers and climate-controlled tents, may run nearly as much per person.

Whether those experiences are seen as environmentally indulgent or simply the spoils of success depends on perspective. The current moment does not lack for luxury brands pledging carbon neutrality or reforestation. But this study adds nuance: consumption may matter less than capital itself.

“This is not an academic discussion,” Schleussner said. “It’s about the real impacts of the climate crisis today.” The authors argue for progressive policy instruments that target the emissions embedded in wealth. That could include portfolio disclosures, financial transaction levies, or carbon-linked tax strategies. It may also mean reframing climate action not just as a matter of moral responsibility, but material consequence.

Still, luxury culture is not monolithic. Even among high-net-worth individuals, a generational shift is visible. Younger consumers have shown stronger interest in sustainability, biodiversity, and regenerative travel. The challenge, perhaps, is that these preferences coexist with an appetite for exclusivity. The $200 sandal made from mycelium leather and the $200,000 yacht charter are not necessarily in opposition — they may belong to the same wardrobe.

None of this means that those with money must retreat from beauty or ambition. But the study invites a deeper reckoning with how influence is wielded — not through press releases or fashion week panels, but through the slow burn of compounding emissions. It’s less about guilt, more about geometry: which lifestyles tip the scale?

“Addressing this imbalance is crucial for fair and effective climate action,” says Schleussner.

“Climate action that doesn’t address the outsize responsibilities of the wealthiest members of society risks missing one of the most powerful levers we have to reduce future harm.”
