We get so little news about the developing world that we often forget that there are literally millions of people out there struggling to change things to be fairer, freer, more democratic, less corrupt.

Saying the Tech Bloom is not commercially driven is like saying Mother Teresa had an interest in the poor.

To be young and aware is to know you’re being lied to; to know that a bright green future is possible; to know that we can reimagine the world, rebuild our cities, redesign our lives, retool our factories, distribute innovation and creativity and all live in a world that is not only better than the alternative, but much better than the world we have now.

Urban retrofitting: creating different sorts of spaces and uses out of places that are already there.

Cities generate most of the global economy, and most of its energy use, resource demands and climate emissions. How we build cities over the next decades will largely determine whether we can deliver a bright green future.

The denser places get, the lower the amount of energy people use to get around it.

By fundamentally changing how we design the places and systems that enable our daily lives, we can slash emissions way beyond the immediate carbon savings - because our own personal emissions are just the tip of a vast iceberg of energy and resources consumed far from our view.
