A Plan for Equality & Prosperity Within Planetary Boundaries

Ensuring Equality and Prosperity for All

The Global Justice Platform's basic objective for equality and prosperity is full income convergence across countries by 2100. There are two main reasons for this target. First, all countries in the Global South aspire to economic prosperity, and any credible framework for global climate cooperation must account for that aspiration.

The Global Justice Platform aims to combine equality & prosperity for all countries with planetary habitability (global warming below 2°C). In 2025, per capita monthly gross national incomes range from 290 Euros in Sub-Saharan Africa to 4,590 Euros in North America/Oceania. Incomes are projected to reach 5,000 Euros in all countries by 2100.

Working Less, Achieving Gender Equality

The first element of sufficiency in the Global Justice Platform is a large reduction in working hours: from about 2,100 hours to 1,000 hours per year per employed person, between 2025 and 2100 (Figure 2). As observed in historical episodes of working-time reduction, productivity growth makes such reductions possible.

In the Sustainable Convergence scenario, annual labour hours decline from about 2100 to 1000 hours globally between 2025 and 2100 so as to reduce material production and consumption. Annual hours around 3000 ≈ 60 hours per week all year long; around 1000 ≈ 25 hours per week during 40 weeks (12 weeks in paid vacation).

Compressing the Income and Wealth Scale

The Global Justice Platform aims at substantial compression of national income and wealth scales over 2026-2100. Global wealth and income taxes are designed both to raise the resources needed by the Global Justice Fund and to curb the concentration of income, wealth, and power at the top of the world distribution.

According to the Global Justice Platform, the share of the top 10% highest incomes in total posttax income in the world is projected to decline from 52% in 2025 to 18% in 2100. The share of the global bottom 50% in posttax income is projected to increase from 8% in 2025 to 38% in 2100, and for the middle 40% from 40% today to 44% in 2100.
