The Global Justice Report: A Plan for Equality & Prosperity Within Planetary Boundaries is a quantified macroeconomic policy roadmap spanning from 2026 to 2100, published by the World Inequality Lab and coauthored by a team of global economists including Lucas Chancel, Thomas Piketty, Gabriel Zucman, and Emmanuel Saez. The report outlines an institutional strategy to simultaneously achieve total global human development convergence and cap global warming at 1.8°C by centring the transition on aggressive wealth redistribution and economic “sufficiency.”

It models a path in which every nation converges to a monthly per capita income of €5,000 while reducing individual working hours to 1,000 annually, phasing out fossil fuels entirely, and shifting the global economy toward resource-light public sectors such as education and health. To finance this restructuring, it proposes a Global Justice Fund funded by a highly progressive global wealth tax, reaching up to 20% annually on billionaires, along with a progressive global income tax. These measures would initially build a World Sovereign Fund designed to permanently sustain equal per capita public goods dividends and democratize international financial institutions.
