CPI’s Climate Finance Tracking Program provides the most comprehensive data and insights into finance flows supporting climate change mitigation and adaptation outcomes.
With time running out to close the climate investment gap, decision-makers require clear, comprehensive information on climate mitigation and adaptation finance. CPI’s unique analysis covers both public and private finance data, translating it into concise reporting and interactive data visualizations. Our research provides a baseline against which to measure progress towards levels of investment consistent with global climate goals.
Our work aims to provide governments, climate funds, development finance institutions, philanthropies, and private investors with accurate data on the current scale, sources, instruments, and uses of climate finance.

Climate Finance by Sector
We use our unique data set and methodological expertise throughout our growing body of sector-specific and thematic work. Our sectoral and thematic areas of analysis include assessing the scale of climate finance, identifying the main actors, and revealing investment gaps. We also highlight opportunities to mobilize finance that address climate goals and create positive economic impacts. Our sectoral climate finance tracking work covers a wide range of topics, including comprehensive analyses of:
- Climate finance for agrifood systems globally
- Financial commitments flowing to energy access in high-impact countries
- Methane abatement finance
CPI has also published innovative methods to better measure finance for climate adaptation.

Climate Finance by Geography
Understanding domestic flows of finance can help governments identify finance gaps, prioritize efforts to better align with climate goals, and unlock the private investment needed for green, resilient development.
Our tracking work supports these efforts by providing robust analyses of how much climate finance is flowing at regional, national, and subnational levels. We also work directly with governments to identify the enabling conditions that can help drive investment to support low-carbon, climate-resilient growth.
