‘An equal and habitable world is possible’: academics set out sweeping vision for planetary survival
A World Inequality Lab report calls for wealth taxes, shorter hours and big public investment to curb inequality and climate risk. It says most people could see incomes rise while warming stays below 2C.
Intelligence analysis by GPT-5.4 Mini
The World Inequality Lab argues that climate stability and broad prosperity can be pursued together through redistribution, lower working time, cleaner diets and a shift away from material-intensive growth. It presents this as an alternative to both climate breakdown and rising inequality.
The report says the world can be like a house with better heating and less waste at the same time. It suggests rich people pay more tax, people work fewer hours, and money goes more to schools and hospitals than to stuff that harms nature.
Analysis
What the report argues
The World Inequality Lab says the world is not trapped between prosperity and climate action. Its new Global Justice Report sets out a path in which living standards rise, inequality falls and temperature increases stay within safer limits.
The proposal rests on what the authors call sufficiency: a life that is healthy and comfortable without endless material consumption. They want average working time cut by more than half, from about 2,100 hours a year to 1,000, alongside diets with less red meat and a larger economic role for education and health.
How the economics changes
The report recommends heavier taxes on billionaires and a redirection of investment away from sectors with large material footprints, such as industry and mining, toward low-consumption activities. Thomas Piketty says each euro added to education and health creates far less material use and energy demand than a euro added in manufacturing, which is why the sector shift matters.
The report also says the financial architecture should be reformed so capital can be moved from the richest individuals into wind, solar and other renewable technologies. In its most ambitious pathway, that would help drive complete decarbonisation and electrification of energy by 2050.
The payoff the authors claim
The paper says 89% of the world’s population could see incomes double by 2100, with the biggest gains in the global south. Billionaires, who make up 0.001% of humanity, would see their share of global wealth sharply reduced, while the bottom half of the world would gain a much larger share.
Key points
- The World Inequality Lab proposes a combined plan for climate action and redistribution.
- It calls for heavy wealth taxes, shorter working hours and lower red-meat consumption.
- The report wants more investment in education and health, and less in material-intensive sectors.
- It says redirecting capital into renewables could speed full decarbonisation by 2050.
- The authors argue the richest people should bear most of the climate burden.
If the report’s plan were followed, most people would see higher incomes over time while the richest would shoulder more of the cost. The authors also say shifting money into renewables could help cut emissions enough to keep warming below 2C.
The plan depends on major political agreement across countries, which the report itself treats as a huge battle. If governments do not adopt the tax, spending and energy shifts, the current path of high emissions and rising inequality could continue.
