This report was developed in the context of OECD’s contributions to the G20 Indonesian Presidency in 2022, to inform the G20 Infrastructure Working Group’s work on sustainable and subnational infrastructure.

This OECD report examines elements that can advance considerations for the environment and data for sustainable infrastructure investment, and discusses what policy actions governments can take to ensure that investors are better able to make investment decisions related to infrastructure assets. The first chapter provides a high-level summary of the G20-OECD Policy Toolkit on Mobilising Funding and Financing for Inclusive and Quality Infrastructure Investment in Regions and Cities that was endorsed by G20 Finance Ministers and Central Bank Governors in October 2022. The second chapter discusses the data needs for infrastructure investment more generally, the ESG approaches being currently proposed, and how this could impact wider ESG data availability. The third chapter brings together studies on legal and regulatory barriers on quality infrastructure investment (QII), to bring a better understanding to what these barriers are. The fourth chapter uses the lens of infrastructure governance to consider how ministries of finance can help align other infrastructure actors promote a pipeline of quality infrastructure projects, ensure that project objectives and reporting correspond with investor expectations, and reduce barriers to sustainable infrastructure investment.

This report is the outcome of cross-directorate efforts of the OECD, with inputs from the OECD Directorate for Financial and Enterprise Affairs, Public Governance Directorate and Centre for Entrepreneurship, SMEs, Regions and Cities. It has benefited from contributions by national government delegates, particularly members of the G20 Infrastructure Working Group, and delegates to the OECD’s Task Force on Long-term Investment Financing (Committee on Financial Markets), Public Governance Committee and Regional Development Policy Committee. The views expressed here do not necessarily correspond to those of the national authorities concerned.
