CREDIT ENHANCEMENT FOR GREEN PROJECTS

The report examines how credit-enhancement mechanisms—such as guarantees, first-loss provisions, and contingent loans—can mitigate the perceived high risks of green infrastructure to mobilize private capital. It analyzes the offerings of major MDBs (including the World Bank, ADB, and EIB) and provides case studies from India, Nigeria, and Mexico to demonstrate how targeting specific risks, such as exploratory costs or tariff volatility, makes projects bankable. The authors conclude that while MDBs have the tools to catalyze green investment, a lack of knowledge among governments and a lack of specialized approval processes for green projects hinder widespread adoption.

• Green infrastructure requires significant investment, estimated between US$36–42 trillion from 2012 to 2030, which represents approximately 2 per cent of global GDP annually.
• Green infrastructure projects face amplified risks compared to traditional infrastructure, including higher reliance on public support for political risks, the use of untested cutting-edge technology, and high upfront costs paired with long payback periods.
• Credit-enhancement mechanisms, such as Partial Credit Guarantees (PCG) and Partial Risk Guarantees (PRG), improve a project's credit rating and confidence, enabling it to attract institutional investors like pension funds that require high credit grades.
• Multilateral Development Banks (MDBs) generally apply the same risk assessment and internal processing mechanisms for both green and traditional infrastructure projects, as well as for both direct loans and credit-enhancement requests.
• In India, a US$128 million partial credit guarantee facility involving the ADB and India Infrastructure Finance Company Limited (IIFCL) helped develop the local bond market by improving project ratings to A or AA, potentially reducing debt costs by up to 1.9 percentage points.
• The Power Sector Guarantees Project (PSGP) in Nigeria utilized a combination of World Bank Partial Risk Guarantees and MIGA political risk insurance to support energy projects, including two greenfield power plants.
• The Inter-American Development Bank (IADB) addressed the high exploratory costs of geothermal energy in Mexico by using a 'loan-guarantee' that is only repaid if the exploratory phase successfully finds energy sources.
• The European Investment Bank (EIB) launched the Project Bonds Initiative in 2012, providing partial credit enhancement through subordinated instruments (loans or contingent facilities) to increase the credit rating of senior project bonds.
• The African Development Bank (AfDB) introduced the Initiative for Risk Mitigation in Africa (IRMA) in 2012 to correlate specific risks—such as foreign exchange and political risk—with available mitigation instruments.
• Widespread adoption of credit enhancement is hindered by a lack of government knowledge regarding available schemes and a lack of technical ability to address specific green infrastructure risks.
