In this third instalment of the Future of Climate Diplomacy mini-series, Climate Briefing hosts Anna and Bhargabi explore what lessons that can be drawn from the history of the climate negotiations and how this can inform the future of climate diplomacy. To do this, they are joined by long-time COP researcher Dr Joanna Depledge (Research Fellow at the Centre for Environment, Energy and Natural Resource Governance and at Centre for Science and Policy, both at the University of Cambridge).

This week's Climate Briefing also includes a chat with Dr Patrick Schröder (Senior Research Fellow at Chatham House's Environment and Society Centre), who explains why the negotiations on a global plastics treaty are important and why the recent round of talks, once again, ended with no deal.
