How do we save the planet? Political economist and economic geographer Brett Christophers argues that first we need to look at our understanding of capitalism and climate, and accept that saving the planet is not profitable enough for markets and the private sector. Today’s consensus that curbing climate change can be done through green electricity and measures such as ever-cheaper solar and wind power aren’t the key, says Christophers, because investment is driven not by price but by profit. He talks about his illuminating book The Price is Wrong: Why Capitalism Won’t Save the Planet, challenging our long-held views about how to combat climate change.
