This week we ask, “In a fair world, who shares the responsibility of reducing carbon emissions?” Christiana goes for a run and comes back with an insightful metaphor to help us, Tom shares about his trip to coal country in West Virginia, and Paul Dickinson explains what the OECD is and why you should know about it. Later in the episode we talk with Angel Gurría, Secretary General of the OECD. He shares why a “big, fat, price on carbon.” is how we truly change our behavior, and our world.
