Today is the start of COP28. And for the next two weeks, Zero will be in the United Arab Emirates, along with more than 70,000 people who will come for the year’s biggest climate conference. These are set to be difficult negotiations. Getting every single country to agree to one common text is a gargantuan task. So for this first episode from COP, we wanted to hear from someone who’s been on the inside; someone who has helped forge global climate agreements from the ashes of broken diplomacy.  Christiana Figueres is the cohost of the podcast Outrage & Optimism, and was formerly the head of the UNFCCC, the body tasked with running COP meetings. She took over the role at a low point in global climate negotiations in 2010 and her efforts culminated in the signing of the Paris agreement in 2015. Now, the world is way off track to meet that goal. So we wanted to hear from Christiana about what can be expected from COP28, the role the fossil fuel industry plays in negotiations, and whether the climate summit is still fit for purpose.
