COP29's climate investment imperative.

Next week, negotiators from around the world will gather in Baku, Azerbaijan, for COP29, the annual climate negotiation organized by the United Nations to hammer out agreements for tackling the climate crisis. It is unofficially being called "The Finance COP" because particular focus will be placed on the financial commitments and mechanisms needed to mobilize the trillions of dollars required to address climate change globally. Such levels of investment sound implausible-but they are achievable, and if the world delays much longer, the economic and social losses will pale in comparison.
