The Global Justice Report was published on 4 June 2026, coordinated by economist Thomas Piketty and the World Inequality Lab, presenting a vision for increased leisure and income alongside reduced material impact through sufficiency measures, wealth taxes, and reform of global financial institutions. Former IPCC chair Robert Watson notes the report addresses a gap in climate policy by integrating social science, while the document explicitly contrasts with a US-led “techno-extractivist” vision championed by Donald Trump and centred on fossil fuel expansion and AI.
