“Go for the megatons.” That’s John Doerr’s recommendation for how we need to combat the existential threat of climate change. Doerr, a venture capitalist and author of the new book Speed and Scale, joins host Bob Safian to discuss our decarbonization efforts, what he calls “the greatest economic opportunity of the next century.” The book quantifies the specific societal needs, in six discrete areas, to achieve a carbon-neutral world. John isn’t arguing that we all need to be vegan ascetics, but rather, the need for collective action – and the critical role that business plays in advancing that movement.  See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
