Climate Change and Global Inequality

One of them has done almost nothing to cause this crisis. The other belongs to a small global minority whose emissions are quite literally rewriting the planet’s future.

This is the core scandal of the climate age: those who did the least to heat the planet are paying the highest price. And more and more, that price is being paid in the Global South.

Unequal responsibility, unequal suffering

Climate change is sometimes described as “the great equalizer.” The data suggests the opposite.

Recent research on global carbon inequality finds that the richest 10% of the world’s population are responsible for about 48% of global emissions, while the poorest 50% account for just 12%.( WID – World Inequality Database+1) Oxfam goes further: in 2019, the richest 1% alone produced as much carbon pollution as the poorest two-thirds of humanity combined. (Oxfam France+1)

Geography deepens this imbalance. Average annual per-person emissions in North America hover around 20 tons of CO₂, compared with about 1.6 tons in Sub-Saharan Africa. (Human Development Reports+1) In other words, a Canadian or American can emit more in a few days than some Africans do in an entire year.

Yet the harshest impacts—crop failures, floods, deadly heat waves—fall disproportionately on countries that contributed very little to the problem. The World Meteorological Organization estimates that by 2030 up to 118 million extremely poor people in Africa will be exposed to droughts, floods and extreme heat if adequate responses are not put in place. (World Meteorological Organization+1)

In Latin America and the Caribbean—responsible for a relatively small share of historic emissions—extreme weather is already raising hunger risks for tens of millions. A recent UN report warns that 74% of countries in the region have been hit by climate-related disasters, with around 41 million people facing hunger in 2023, a trend that climate change threatens to worsen. (Reuters+1)

The pattern is clear: emissions are concentrated in the Global North and among the global rich. The damage is concentrated in the Global South and among the global poor.

A crisis of class as much as of geography

The climate story is often told as a simple standoff between rich countries and poor ones. Reality is messier—and in some ways, more damning.

Within-country inequality has become at least as important as the gap between nations. A landmark study in Nature Climate Change calculates that the wealthiest 10% of the world’s people are responsible for around two-thirds of global warming since 1990. (Nature+1) Another analysis finds that American and Chinese high-emitters alone have driven a two- to threefold increase in heat extremes in vulnerable regions such as the Amazon, Southeast Asia and southern Africa. (Nature+1)

In other words, the climate crisis does not simply pit “North” against “South.” It pits high-consuming elites everywhere—including in major emerging economies—against the poor in every region.

Oxfam and the Stockholm Environment Institute recently showed that the wealthiest 0.1% of Americans emit carbon at roughly 4,000 times the rate of the world’s poorest 10%, consuming the planet’s remaining “safe climate space” at 183 times the global average. (The Guardian+1) Their private jets, mega-yachts and luxury portfolios are not just symbols of inequality; they are active engines of climate breakdown.

Meanwhile, countries like Burundi, responsible for less than 0.02% of global greenhouse gas emissions and just 0.06 tons of CO₂ per person, rank among the most climate-vulnerable nations in the world. (Wikipedia+1)

This is why climate activists increasingly speak of “climate apartheid”—a world in which the rich can pay to adapt or move, while the poor are left to face rising seas, failed harvests and ever more dangerous storms.

The Global South’s climate bill

As the atmosphere warms, the bill arriving in the Global South is measured not only in degrees Celsius, but in lives and livelihoods.

• A UNHCR report estimates that climate-related disasters displaced 250 million people over the past decade—roughly 70,000 people every single day. Three-quarters of those displaced live in countries highly vulnerable to climate risks, many of them in Africa and Asia. (The Guardian+1)
• Africa is already losing up to 5% of GDP in some countries due to climate impacts, according to African Union and UN assessments. (UNEP – UN Environment Programme+1)
• In Latin America, droughts and floods threaten key agricultural regions that feed both local populations and global markets. (Reuters+1)

These are not abstract future scenarios. They are today’s lived reality in low-lying Pacific islands where graves wash into the sea, in the Sahel where pastoralists struggle to find pasture, and in South Asian cities that now experience lethal wet-bulb temperatures—heat and humidity so intense that even a healthy person resting in the shade can die.

A growing body of research argues that this constitutes not just misfortune, but a form of measurable economic harm inflicted by high-emitting countries and individuals. One recent analysis suggested that, under a fair accounting of historical responsibility, the Global North may owe the Global South some $5 trillion per year in “climate debt” through mid-century, even if warming is kept near 1.5°C. (Climate Action Network+1)

It is this logic that underpins increasingly forceful calls for climate reparations.

Supporters: “We broke it, we buy it”

From Pacific island states to African negotiators, many in the Global South argue that climate justice demands more than vague promises of solidarity. It demands money, technology and a redistribution of power.

At recent UN climate conferences, these governments have pushed three core ideas:

Loss and damage finance
Beyond funding for mitigation (cutting emissions) and adaptation (building resilience), they insist on a dedicated stream of money for loss and damage—to deal with the destruction that can no longer be avoided. Under intense pressure from vulnerable countries and civil society, governments agreed at COP27 to create a new Loss and Damage fund, and formally established it at COP28. UNFCCC+2World Economic Forum+2 At COP29 in Baku, countries set a higher overall climate finance goal and clarified that loss and damage support must focus on particularly vulnerable developing countries. UNFCCC+1

Historical responsibility and “fair shares”
European and North American leaders often point out that their share of current annual emissions is shrinking compared to China and other emerging economies. Critics respond that this ignores cumulative emissions—the total carbon dumped into the atmosphere since the industrial revolution—and much higher per-capita footprints. Recent debates in Europe, for example, highlight that the EU’s historical responsibility and wealth mean its “fair share” of climate action would require much deeper cuts and more international finance than current targets imply. (Le Monde.fr+1)

Making the polluters pay
Advocates argue that climate justice requires not just transfers from rich countries to poor ones, but taxing the individuals and corporations most responsible. Oxfam’s latest reports call for steep taxes on the super-rich and on fossil fuel windfall profits to both cut emissions and raise trillions for climate action. (Oxfam International+2Oxfam International+2)

Behind these proposals is a simple moral claim: those who profited most from fossil-fuelled growth should help those who are now paying the human cost.

Critics: “Reparations” or endless liability?

Not everyone accepts the language—or the implications—of climate reparations.

Some policymakers in the Global North argue that framing climate finance as a legal or moral debt risks entrenching geopolitical divides and making climate cooperation harder. They worry about open-ended liabilities: if rich countries are held responsible for every climate-linked disaster, how can the eventual bill be contained?

Others point to governance failures and corruption in some recipient states, warning that large cash transfers without strong accountability could be wasted, siphoned off by elites, or used to entrench authoritarian regimes. They insist that taxpayers in Europe or North America, many of whom struggle with their own cost-of-living crises, will not support what they perceive as blank checks to distant governments.

There is also a growing debate about responsibility within the Global South. Emerging economies such as China, India, Brazil and Gulf states now have large middle classes and ultra-wealthy elites whose per-capita emissions rival or exceed those in the West. Should they be treated solely as victims of a Western-made crisis, or as co-responsible powers that must also pay into global climate funds and constrain their own high emitters?

These critics are not always arguing in bad faith. They raise real questions about design, fairness and feasibility. But too often, their concerns become a convenient excuse for inaction—a way to defend a status quo that is far from neutral.

What climate justice could actually look like

If we strip away the rhetoric, what would a fairer climate order look like in practice?

Target the real high emitters, wherever they live
The data is unequivocal: the wealthiest 10% of the global population—North and South—drive most of the warming. (Nature+1) Climate policy that focuses only on average national emissions misses this. Progressive wealth and luxury emissions taxes, including on private jets, mega-yachts and high-carbon investments, could slash the footprint of the global elite while raising revenue for climate action.

Scale up and reform climate finance
The current system of climate finance—fragmented funds, complex application processes, loans instead of grants—is nowhere near matching the scale of the crisis. Even with recent pledges, the Loss and Damage fund is still a fraction of estimated needs. (UNFCCC+1) A serious approach would include:

• Much larger grant-based funding for adaptation and loss and damage
• Clear, transparent criteria for access
• Strong civil-society oversight in recipient countries to ensure money reaches frontline communities rather than just central bureaucracies

Invest in data, research and local expertise in the Global South
A recent Nature Communications article warns that gaps in climate data and research in the Global South perpetuate inequalities, because the places suffering the most are often the least studied. Funding universities, research institutes and early-career scientists in Africa, Asia, Latin America and small island states is not charity—it is a precondition for designing effective, locally grounded solutions.

Support just transitions, not just megaprojects
Renewable energy is booming in parts of the Global South, from solar farms in Morocco to off-grid mini-grids in East Africa. But without safeguards, the green transition can repeat old patterns of extraction—new mining for lithium and cobalt, new land grabs for biofuels and carbon offsets. Climate justice means prioritizing energy access for the poor, fair wages for workers and genuine participation for Indigenous and local communities in decisions that affect their land. (World Meteorological Organization+1)

Recognize climate displacement as a political, not just humanitarian, issue
When climate disasters displace hundreds of millions, as UN agencies now warn is happening, this is not only a humanitarian problem; it is a question of rights, borders and responsibility. (The Guardian+1) The people uprooted by floods in Sudan or drought in Central America did not choose this future. Any meaningful climate bargain will have to confront migration—who gets to move, who must stay, and who will help them rebuild.

Beyond charity: a test of the global order

The climate crisis is not just about physics; it is about power.

Who gets to keep emitting—and at whose expense? Who decides which regions are protected and which are sacrificed? Who sits at the table when rules are written, and who waits outside for aid that may never come?

Right now, the answers are brutally simple. A small minority of humanity—disproportionately in the Global North, but also in wealthy enclaves of the South—continues to consume far more than the planet can sustain. The costs are exported to the rest of the world, in the form of flooded homes, scorched fields and homes emptied by migration.

Supporters of climate justice say this cannot last. They argue that without confronting inequality head-on—between and within countries—the world will fail both to stabilize the climate and to maintain any credible claim to fairness. Critics warn that pushing too hard on historical responsibility and reparations may trigger a backlash and stall cooperation.

Both sides are right about one thing: the stakes are enormous.

The farmer watching the sea rise in Bangladesh, the herder in the Sahel searching for grass, the family in a Brazilian favela rebuilding after yet another flood—they are not simply victims of bad luck. They are living at the sharp end of a global economic model that has treated the atmosphere as a free dumping ground for the privileged.

In that sense, the question facing the world today is not only how fast we cut emissions. It is who gets to keep burning carbon—and who gets a fair chance to survive what that burning has already unleashed.

Until we answer that honestly, “climate action” will remain, for many in the Global South, another word for a bill they did not run up, but are being forced to pay.

On a hot afternoon in coastal Bangladesh, a farmer watches saltwater creep into his rice field. A cyclone a few months earlier pushed the sea several kilometers inland; now his harvest is half what it was. Thousands of kilometers away, a frequent flyer boards a private jet for a weekend trip. Both individuals live on the same warming planet. But they do not live in the same climate reality.

One of them has done almost nothing to cause this crisis. The other belongs to a small global minority whose emissions are quite literally rewriting the planet’s future.

This is the core scandal of the climate age: those who did the least to heat the planet are paying the highest price. And more and more, that price is being paid in the Global South.
