Decarbonizing the global economy and increasing climate resilience worldwide will require trillions of dollars, largely from private sector investors. What novel mechanisms, collaborative efforts, and policies can accelerate the mobilization of private capital? International and domestic thought leaders will exchange ideas at the second annual “From Billions to Trillions” summit.

The event will build on the successful 2024 summit, which convened over 500 attendees and explored how the Inflation Reduction Act could catalyze private climate investment in the United States. Subsequent developments have called into question the durability of that model, and raised questions about the types of investments needed to address climate change and where they will come from.

The 2025 summit will update the domestic decarbonization dialogue to reflect these new realities, while also expanding it to include global climate finance challenges and opportunities.
