"We have to demand the change and make that change.” In this episode of Clear The Air, Sadiq Khan sits down with the Mayor of Los Angeles, Eric Garcetti. Eric reveals how he convinced more than 400 mayors from across the United States to adopt the Paris Agreement after Donald Trump pulled the U.S. out of the pact. The pair discuss how mayors are leading climate action across the world, what they’re doing to reduce emissions in their cities and how LA plans to host the greenest Olympic Games ever.
