A Full-Spectrum Approach to Climate Finance

The legacy approach to climate finance has focused on volume rather than impact. Today, the global climate finance system faces unprecedented pressures: rising debt, inflation and geopolitical instability are reshaping how countries access capital for energy transition and climate resilience. In a world of shifting trade flows, surging AI-driven energy demand, and renewed emphasis on domestic self-reliance, climate finance must evolve. A “full-spectrum” approach is needed that integrates fiscal, monetary and regulatory tools into coherent, nationally-led systems. Under the Brazilian Presidency, the Circle of Finance Ministers is preparing the Baku-Belém Roadmap, which aims to mobilize US$1.3 trillion annually by 2035 from public and private sources to help developing countries reduce greenhouse gas emissions and implement Nationally Determined Contributions and National Adaptation Plans. Developed countries are expected to lead by mobilizing US$300 billion per year, with an emphasis on grants, concessional finance, non-debt instruments and multilateral initiatives. Drawing on recent policy innovations and prototypes, this paper provides actionable strategies to operationalize the Roadmap across the Circle’s five strategic priorities.
