Against the bleak techno-authoritarian futures now being sold to us, a radical new vision for global progress in the 21st century feels urgently needed. The most credible vision is one in which the habitability of the planet is a precondition for human development and equality. Our new report examines the conditions required for the world to progress towards this ambition on an economically and ecologically compatible path, by the end of the century. Its conclusion? A global transformation that reconciles planetary habitability and high standards of wellbeing for all is possible – as long as three conditions are simultaneously met. Fast decarbonisation of energy systems is necessary. But we also need a major shift away from overconsumption towards “sufficiency”. This would involve a sharp reduction in labour hours and the use of raw materials, along with big changes in consumption patterns, food habits, land use and forest cover. Financing and politically sustaining decarbonisation and sufficiency will require a drastic reduction in inequality of income, wealth and power, between countries and within them. This reduction of global inequality is compatible with deep decarbonisation; indeed, it is a necessary condition for shared prosperity on a finite planet.

When we are preoccupied by poverty, “we have less mind to give to the rest of life.” Poverty does not just deprive people of security and comfort; it siphons off their brainpower, too.

A higher minimum wage is an antidepressant. It is a sleep aid. A stress reliever. Vocal segments of the American public, those with brain space to spare, seem to believe the poor should change their behavior to escape poverty. Get a better job. Stop having children. Make smarter financial decisions. In truth, it’s the other way around: Economic security leads to better choices.

Somehow, the United States has the unique distinction of lacking universal healthcare while still having the most expensive healthcare system in the world.
