COP 26 is the most important international climate conference since the Paris Agreement of 2015.   On the line with me to offer a preview of what to expect from this major UN climate meeting is Pete Odgen, Vice President for Energy, Climate, and the Environment at the United Nations Foundation. He is a veteran of many previous COPs and in our conversation he discusses the key issues up for negotiation in Glasgow and the broader geopolitics of climate change diplomacy. This includes a deep dive into how both China and the United States are approaching COP26 and thorny questions around climate finance.
