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.

Our Focus


What is the current state of global climate finance?

Presenting the most comprehensive data available on global climate finance flows, including granular data by source, financial instrument, region, use, and sector.


How far are we to closing the climate investment gap?

Using both bottom-up and top-down analyses to understand the finance required by region, sector, and type of capital, and examining the roles of public and private investment in closing the climate finance gap.


What should be prioritized to improve impact and outcomes?

Creating frameworks and assessing historical data to understand the effectiveness and efficiency of climate-aligned and unaligned finance.

Ensuring the quality of our work

Data Science

CPI is continually evolving our use of data science tools to deliver unique insights and drive impact. We improve the quantity and quality of climate finance data access through tools like web scraping, enhanced data processing, and multi-language programming. We also contribute to open-source tools and datasets for climate action.


CPI leverages a decade of finance tracking methodology expertise to ensure consistency and comparability in our data, especially important to shed light on complicated topics and data sets that cross industries, geographies, and the private and public sectors.

Convening and dissemination

CPI breaks down silos and brings together governments, development finance institutions, the private sector, and civil society to form consensus around shared goals, pragmatic solutions, and implementation priorities.

Our climate finance analysis and publications provide deep-dive insights by sector and geography

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.



Top-down Climate Finance Needs

CPI collects and standardizes data on climate finance needs from a wide variety of scenarios to provide a comprehensive and unique understanding of the scale of the climate finance gaps in different sectors.


Inclusive Climate Finance: Improving Access for Marginalized Populations in Indonesia

This report, developed in partnership with Hivos Indonesia, aims to assess the current climate finance landscape in Indonesia and explore possible ways in which climate finance can be mobilized to target the marginalized populations.


Landscape of Guarantees for Climate Finance in EMDEs

Cross-border guarantees are an important but underused tool for leveraging private capital in climate finance, particularly for emerging markets and developing economies. CPI conducted a comprehensive scoping analysis to gain a baseline understanding of the global landscape of guarantees. These instruments were analyzed based on financial instrument coverage, sector and climate focus, geographic reach, and types of risk coverage.
