World Inequality Lab Unveils a Comprehensive Plan for Equality and Planetary Survival The new Global Justice Report, produced by the World Inequality Lab (WIL), outlines a set of policy proposals designed to raise living standards, halve global inequality and limit temperature rise to 2 °C. The authors argue that a coordinated shift toward sufficiency – living well without excessive material consumption – is both feasible and essential. Projected Economic and Climate Outcomes of the Plan Income growth: 89 % of the world’s population could see their incomes double by 2100. Climate target: Global heating would stay below a 2 °C rise above pre‑industrial levels. Wealth redistribution: Billionaires’ share of global wealth would fall from 6 % to 0.05 %; the bottom 50 % would rise from 2 % to 30 %. Working hours: Average annual work time would be cut from 2,100 hours to roughly 1,000 hours (about a 2½‑day work week). Dietary shift: Reducing red‑meat consumption to curb deforestation and biodiversity loss. Public investment: Education spending would rise to €8,400 per person and health spending to €14,400 per person, more than doubling current levels. Potential Transformations for Global Inequality and Environmental Policy The report positions its vision as a counter‑narrative to the “far‑right techno‑extractivist” outlook that predicts continued fossil‑fuel expansion and widening disparity. By linking inequality research with climate science, the authors aim to create a political coalition capable of reforming the world’s financial architecture. Thomas Piketty, co‑director of WIL, emphasizes that a euro invested in education or health generates three to four times less material footprint than a euro in manufacturing, underscoring the importance of sectoral shifts. Challenges Ahead and Path to Implementation Realising the plan will require overcoming entrenched political interests, especially those championing low‑tax, high‑growth models. The authors warn that without cooperative redistribution, societies risk “disastrous outcomes both on the environment and on social grounds.” Building a global coalition, securing public support for wealth taxes and re‑orienting investment toward low‑consumption sectors are identified as the critical next steps.

A New Vision for Global ProsperityIn our increasingly dystopian world, the World Justice Report offers a utopian antidote by outlining how to build a prosperous, equitable world within safe planetary boundaries. This ambitious plan from the modern eco-socialist left presents a comprehensive vision for the future that could see the majority of people working less and earning more by the end of the century while keeping temperatures down and avoiding much of the current destruction of nature.The Core Principles of the Justice ReportThe report incorporates important concepts of "sufficiency" and "planetary habitability," addressing the fundamental question of how to reduce the material impact of economic activity—a topic long ignored by the traditional left. By widening the definition of prosperity and emphasizing "sufficiency," the report demonstrates that quality of life is more valuable than quantity of material goods, echoing ancient philosophies of a "golden mean" and Bhutan's concept of "gross national happiness."Challenging Economic OrthodoxyThomas Piketty, one of the coordinators of the report, argues that the ambition of the mega-rich has become unrealistic and undesirable. "Their new dream is to cover the entire planet with data centres," Piketty states, "This is their economic project for the world. But everybody can see that this is just going to increase the material footprint of our economy, that this is going to make global warming even worse."The Alternative to Techno-ExtractivismThe report stands in stark contrast to the far-right techno-extractivist vision currently being championed by the US president and his supporters in Silicon Valley, who are putting artificial intelligence ahead of renewable technology. In the quest for "energy dominance," the US is using tariffs and military power to widen markets for oil, gas and coal—a strategy that drives the world toward catastrophic levels of global heating and inequality.Bridging the Climate Science GapThe report fills a significant hole that has existed since the inception of the global climate science infrastructure in the 1990s. Robert Watson, a former chair of the UN Intergovernmental Panel on Climate Change, noted that if he could go back in time, he would have added more social scientists to the climate discussion. The "pure scientists" from physics and chemistry initially believed data alone would persuade governments to act, but later wished they had taken more account of social dynamics, economics, politics and psychology.Overcoming the Green Growth IllusionThe report challenges what Piketty calls the "illusion of classless ecology" or the "green growth illusion" that everything will be solved by producing more without worrying about distribution, sufficiency, or structural transformation. This illusion, he argues, has made green policy unpopular for many lower and middle-income voters by ignoring the social dimensions of climate action.The Path to Cultural Transformation"Sufficiency does not mean degrowth," explains Cornelia Mohren, Environmental Coordinator of the World Inequality Lab. "It is about less working hours, a different composition of consumption, and more health and education." The authors emphasize that they don't want to force people to change their lifestyles but rather initiate a cultural shift in how society perceives the good life.A Future Forged in CrisisPiketty acknowledges that crises are inevitable but argues it's important to initiate debates now so that alternatives are already in people's minds and will become more palatable in the future. "People need to get accustomed to the fact that big change will happen in any case," he states. "We are not in a situation where things can just continue as they are forever." The report remains open for suggestions and revisions, inviting global participation in shaping this alternative vision for our shared future.
