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.

This OECD and TIPS working paper estimates and analyses publicly-mobilised private finance for climate action in South Africa (2010-2015). The mobilisation effect of public finance is estimated through an analysis of co-finance data. A pilot-methodology (the “investor perspective”) then expands the analysis to incorporate the role of financial support provided by policies in the renewable energy and energy efficiency sectors.

Results suggest that, in the South African context domestic public actors play a key mobilisation role by providing financial support through policies and, to a lesser extent, project-level co-finance. However, further methodological work is required to also take into account the effect of upstream public interventions such as public finance intermediated through funds and credit lines, capacity building activities, non-monetisable policies.

This working paper presents the results from the 2016 survey conducted by the OECD Development Assistance Committee to measure amounts mobilised from the private sector in 2012-2015 by official development finance interventions, including for climate-related activities. The survey covers guarantees, syndicated loans, shares in collective investment vehicles, direct investment in companies, credit lines.

The results indicate that during 2012-2015 USD 81.1 billion was mobilised from the private sector, mainly through guarantees for which the amounts mobilised represented 44% of the total. They also show that most of the amounts mobilised supported projects in middle-income countries (77%), especially in Africa which was the main beneficiary region (30%).

Release of "2020 Projections of Climate Finance Towards the USD 100 Billion Goal"

Based on new econometric analysis, this OECD working paper assesses the impacts of climate mitigation policies and of the investment environment on investment in renewable-power generation since 2000 in OECD and G20 countries. The analysis also assesses how the investment environment and policy misalignments influence the effect of climate mitigation policies in encouraging renewables investment.

In doing so, the report contributes to an emerging body of work that explores evidence-based options for estimating the effect of policies on investment. Such work complements progress being made in tracking private finance mobilised by public climate finance.

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.
