The planet’s economist: has Kate Raworth found a model for sustainable living?

Her hit book Doughnut Economics laid out a path to a greener, more equal society. But can she turn her ideas into meaningful change?

Consider the electric car. Sleek and nearly silent, it is a good example of how far the world has progressed in fighting the climate crisis. Its carbon footprint is around three times smaller than its petrol equivalent, and unlike a regular car, it emits none of the greenhouse gases that warm the planet or noxious fumes that pollute the air. That's the good news. Then consider that the battery of an electric car uses 8kg of lithium, likely extracted from briny pools on South America's salt flats, a process that has been blamed for shrinking pasturelands and causing desertification.

The 14kg of cobalt that prevent the car's battery from overheating have probably come from the Democratic Republic of the Congo, where cobalt mines have contaminated water supplies and soil. As the demand for electric vehicles grows, the mining and refining of their components will intensify, further damaging natural ecosystems. By 2040, according to the International Energy Agency, the global demand for lithium will have increased more than fortyfold.
