Tracking private climate finance, together with flows of public finance, is a key task in monitoring progress in the international effort to address climate change. Yet, there are significant data, methodological and knowledge gaps on climate-related private finance, and available information is scattered. Further research and better co-ordination of on-going initiatives are therefore required to improve their identification, measurement or estimation and reporting.

The Research Collaborative is an open network, co-ordinated and hosted by the OECD, of governments, research institutions and international finance institutions. The goal is to partner and share best available data, expertise and information to advance policy-relevant research in a comprehensive and timely manner. The project is designed to serve as a co-ordinating platform for identifying research priorities and gaps, sharing information, weaving a coherent narrative across what would otherwise be disparate research outputs, as well as communicating results to raise awareness in this area.

A number of developed countries and multilateral institutions have made significant forward looking climate finance pledges. On that basis, the OECD was asked to provide analytical support to the preparation by developed countries of a roadmap towards achieving the USD 100 billion climate finance goal. This technical note sets out the resulting projections for climate finance in 2020 along with the underlying assumptions and methodologies used. 

The projected overall range is driven by the level of public finance but is conditional on the fraction of projects likely to mobilise private finance as well as the corresponding private-public finance ratio.

In 2015 the OECD Development Assistance Committee (DAC) carried out a survey to i) pilot methodologies for measuring private finance mobilised by guarantees, syndicated loans and shares in funds, ii) assess the feasibility of collecting data on amounts mobilised by credit lines and direct investments in companies, and iii) collect data on amounts mobilised from the private sector through these mechanisms in 2012-14.

This DAC working paper presents the results from the survey, including for climate-related activities. More information about this on-going work can be found on the DAC webpage.

adaptation: exploring data and methods”

This OECD working paper explores the extent to which currently-available secondary data make it possible to estimate private finance mobilised by developed countries for renewable energy projects in developing countries.

Findings underline the need for improved primary data collection, in particular by public climate finance providers on private co-finance, building upon the recent progress already achieved.

The paper also highlights that very careful and transparent use should be made of private finance leverage ratios, as they are highly sensitive to underlying calculation methods as well as to varying mandates of development agencies and institutions.

This Climate Policy Initiative report in collaboration with the OECD, advances understanding of how to assess publicly-mobilised private investment in climate resilience.

It does so by developing, testing and evaluating a range of methodological options to estimate the amount of private finance mobilised by developed countries’ public finance interventions for climate adaptation in developing countries.

While on-going climate finance tracking efforts focus on measuring private finance mobilised directly, this study also explores possibilities to estimate private finance mobilised indirectly by e.g. by public finance for capacity building or project demonstration.
