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.

Release of “Estimating publicly-mobilised private finance for climate action: A South African case study”

This Policy Perspectives summarises work conducted since 2013 on estimating publicly-mobilised private finance. The brochure first introduces a typology of the potential effects that public interventions and enabling conditions have on private finance. It then provides an overview of the state of play on methodologies:

  • Progress made, in particular by the OECD DAC, on developing methodologies and collecting data to measure mobilisation by public finance instruments.
  • An overview and comparison of three types of approaches (cash flow, consultation and econometrics-based) for estimating mobilisation by policies and capacity building.

On both aspects, the brochure puts forward possible next steps for improving data availability and methodologies.

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.

Release of “Amounts Mobilised from the Private Sector by Official Development Finance Interventions

Release of “The Empirics of Enabling Investment and Innovation in Renewable Energy”

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.

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

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 under the Research Collaborative on tracking private finance mobilised by public climate finance.
