Grace speaks to Holly Jean Buck, Assistant Professor of Environment and Sustainability at the University of Buffalo about her new book Ending Fossil Fules: Why Net Zero Is Not Enough. They discuss the meaning of net zero, the different trajectories we might use to get there, and how these different paths might ease or exacerbate other ecological, social and political challenges the world faces today.You can support our work on the show by subscribing to our Patreon (https://www.patreon.com/Aworldtowinpod), where you'll get access to full-length versions of the interviews.
