Imagining Cities That Can Save The Planet: Alex Steffen Talks About Carbon Zero

"The economy of the future is not about recreating the 20th Century again and selling it to the world’s emerging economies. It’s about figuring out here, in the world’s wealthiest cities, how humanity can live in ecological balance, genuine prosperity and comparative safety—and then being able to export the skills and insights we learned doing it so others can do the same. We’re becoming a planet of a thousand new major cities. The economy of the 21st century is a city-building economy. It’s within our power to make it a carbon zero one, too; and to be blunt, civilization depends on our success."
