Rathi’s book documents a bank of the solutions we can deploy to address the climate emergency. Journeying across five continents Rathi tells the story of the unlikely heroes driving change, from Danish students who helped to build the world’s longest-operating wind turbine to the Chinese bureaucrat who did more to make electric cars a reality than Elon Musk.

He argues the root of the climate crisis is “not capitalism but the corruption of capitalism.” He believes capitalism is going green and that world economies are moving to clean tech as prices plummet.
