New Plan Shows How to Tackle Inequality and Climate Together

Imagine a world where you work half as much, earn a comfortable living, and the planet stays livable for your grandchildren. A groundbreaking report from the World Inequality Lab says this isn't a fantasy but a realistic possibility if we're willing to make bold choices about fairness.

The Global Justice Report, released Thursday, challenges the tired idea that fighting climate change means accepting less. Instead, it shows how nearly 90% of the world's population could double their income by 2100 while keeping global heating below 2°C.

The plan centers on a concept called "sufficiency." Rather than endless consumption, people would work less and focus more on health, education, culture, and caring for each other. By 2100, everyone in every country would earn around €5,000 (£4,250) monthly, with poorer regions growing faster and wealthy nations slowing down but distributing income more fairly.

Working hours would drop from about 2,100 hours per year today to roughly 1,000 by century's end. That's not about being lazy but redirecting human energy toward lower-carbon sectors like healthcare, education, and community care.

The report also tackles gender equality directly. Women and men would earn equal pay and share paid work and domestic duties equally, recognizing that fairness at home is inseparable from progress everywhere else.

Making this work requires massive financial shifts. A Global Justice Fund, paid for by taxing the richest 1% globally, would spend about 10% of world GDP annually on climate investment, health, and education. That's 25 times more than current international aid.

The wealth redistribution would be dramatic. The bottom half of humanity would see their share of global wealth jump from 2% to 30%, while billionaires' share would plummet from 6% to 0.05%. The authors argue this isn't just fair but necessary, since the ultra-wealthy profited most from high-carbon growth and control the capital needed for change.

Energy systems would transition rapidly away from fossil fuels, with electricity coming from clean sources by mid-century. But technology alone won't save us. Without addressing inequality and consumption patterns, the energy transition becomes too expensive and politically fragile.

The Ripple Effect

When the report's authors calculated total wellbeing, including extra leisure time and avoiding climate catastrophe, they found that over 99% of people would be better off. That's not just about money but quality of life, time with family, and a stable planet.

Report co-author Thomas Piketty and his colleagues acknowledge the plan is radical. But they insist the real question isn't whether this is technically possible but whether we'll choose it over a future of deepening inequality, climate chaos, and instability.

The roadmap exists, and the math checks out.
