Climate change is posing ever greater risks to global security, stability, and prosperity just as the international landscape is becoming more complex and contested. Geopolitical friction, industrial competition, shifting power dynamics, and energy security concerns are reshaping how nations engage. How must diplomatic efforts to address the climate crisis evolve to remain effective? What constellation of traditional diplomatic arenas and newer, emerging ones collectively accelerate climate action in this era of disruption? How can they best bolster implementation and delivery on the ground?  

At this event, distinguished global experts will engage in a candid, provocative conversation on revitalizing climate cooperation. The event will explore strategic use of diverse diplomatic arenas, placing the UNFCCC within a much wider ecosystem that includes new coalitions of the willing, expanding regional cooperation, and tighter links to core national priorities like trade, finance and security.

  • Catherine McKenna, Former Minister of Environment and Climate Change of Canada, CEO of Climate & Nature Solutions
