The richest 10% drive 77% of emissions. Can climate justice close the gap?

The world's climate crisis is being driven disproportionately by its wealthiest citizens, yet a more equitable and sustainable future remains within reach, according to the newly released Global Justice Report.

The report, published by the World Inequality Lab's Global Justice Project, argues that the richest 10 per cent of the global population are responsible for roughly 77 per cent of emissions linked to private capital ownership, while the poorest half account for only a tiny fraction.

Despite this imbalance, the authors contend that reducing inequality and tackling climate change need not be competing objectives. Instead, they say, both challenges can be addressed simultaneously through ambitious reforms to the global economy.

At the heart of the report is a provocative claim: the world can achieve broad-based prosperity without exceeding environmental limits. The researchers envision a future in which living standards rise across countries, extreme poverty is eradicated and economic opportunities are more evenly distributed, even as greenhouse-gas emissions decline. Such an outcome, they argue, would require a dramatic shift in how wealth, investment and resources are allocated globally.

The study highlights the growing concentration of wealth as a major obstacle to climate and social progress. According to its findings, the top 10 per cent control around three-quarters of global wealth, while the bottom half owns only a small share. This concentration, the report argues, not only fuels economic inequality but also drives emissions through ownership of carbon-intensive assets and investments.

To address these disparities, the report proposes the creation of a Global Justice Fund financed through measures such as taxes on extreme wealth and international cooperation on financial transparency. The proceeds would be directed toward investments in clean energy, healthcare, education and infrastructure, particularly in lower-income countries. The goal is to accelerate development while helping nations transition to low-carbon growth pathways.

The report arrives amid mounting evidence that climate change and inequality are increasingly interconnected. Recent research has shown that wealthier individuals and households contribute disproportionately to global warming through both consumption and investments, while poorer communities bear the brunt of climate-related disasters. One study found that the wealthiest 10 per cent of the global population were responsible for roughly two-thirds of global warming since 1990.

The authors acknowledge that their proposals would require unprecedented levels of international coordination and political will. Yet they argue that the alternative — rising inequality, escalating climate damage and deepening geopolitical instability — would be far more costly.

Ultimately, the report presents a stark choice: continue with an economic model that concentrates wealth and emissions among a privileged few, or pursue a new framework in which prosperity, sustainability and fairness reinforce one another rather than compete.
