In this episode, we sit down with Lou Leonard, a veteran of the negotiations leading up to the Paris Climate Agreement, to unpack what that landmark deal got right, where it still falls short, and what's changed since. From the strategic logic behind keeping Paris non-binding, to the legal cornerstone of U.S. climate regulation known as the Endangerment Finding, we explore how climate policy is being reimagined at every level and what it really takes to drive meaningful action.
