Global Justice Report Maps Path to 89% Income Gains Within 2C Planetary Limits
3 articles · Updated · The Guardian · Jun 4
Summary
89% of people could see incomes double by 2100 while global heating stays below 2C, according to the Global Justice Report’s model for a richer, more equal world within ecological limits.
The plan ties shorter working hours, higher wages, wealth taxes and reformed global finance to a broader idea of “sufficiency,” arguing climate policy failed when it ignored inequality, distribution and quality of life.
Thomas Piketty and other authors cast that framework against Donald Trump’s “energy dominance” agenda and Silicon Valley’s AI-led, data-centre-heavy growth model, which they say would deepen emissions, extraction and inequality.
The report also challenges both the traditional left’s fixation on GDP growth and the right’s rejection of planetary boundaries, and its authors say they are opening the blueprint to revisions as climate and political crises intensify.

The Global Justice Report 2026: How 89% Could Double Their Incomes by 2100 Within Planetary Limits
Overview
The World Inequality Lab's Global Justice Report, released on June 4, 2026, offers a comprehensive and quantified roadmap to address the urgent 'polycrisis' of climate breakdown, rising inequality, and political extremism. The report sets out a bold plan to dramatically reduce global inequality while respecting planetary boundaries and ensuring a habitable future for all. If its proposals are implemented, 89% of the world's population could see their incomes double by 2100. This vision presents a positive and feasible alternative to current techno-authoritarian and nationalist-populist approaches, aiming for a just and sustainable world.
