Financial Aggregation Blueprints for Urban Climate Infrastructure

This report by the Climate Policy Initiative provides detailed blueprints for three types of financial aggregation instruments—municipal pooled procurement, municipal green bonds, and municipal insurance pooling—to help cities close the urban financing gap for climate infrastructure.

• There is a significant urban financing gap for climate action; while cities require USD 5-6 trillion annually for mitigation and adaptation, the average annual climate finance flow to cities is only USD 384 billion.
• Municipal pooled procurement allows cities to achieve economies of scale and lower unit prices by aggregating demand for green technologies like LED lighting and electric vehicles, while reducing individual transaction costs.
• The RAMCC Trust Fund in Argentina serves as a pooled procurement platform for over 30 municipalities to purchase climate-smart technologies, such as LED lights, requiring participating cities to have a Climate Action Plan as a pre-condition.
• India's 'The Grand Challenge' implemented a mobility-as-a-service model in 2022 to deploy 5,450 e-buses, shifting from an upfront capital expenditure model to an operational expenditure model to make the transition affordable for municipal authorities.
• Municipal green bonds enable cities to access long-term private capital and diversify financing sources by bundling smaller projects into a single investment vehicle that meets the minimum ticket-size requirements of institutional investors.
• Mexico City issued the first municipal green bond in Latin America in 2016, raising USD 50 million for clean transport, water distribution, and LED lighting, utilizing federal government financial guarantees because municipal borrowing is prohibited by national regulation.
• Manila Water issued a USD 500 million sustainability bond in 2020 on the Singapore Stock Exchange to attract international ESG investors for water and wastewater treatment facilities following liquidity issues in the domestic market.
• Municipal insurance pooling allows cities to buy coverage as a block to achieve lower premiums and provides quicker access to emergency relief funds if parametric insurance is used.
• The Urban Infrastructure Insurance Facility (UIIF) and the Municipal Risk Pool in South Africa’s Western Cape are both in the design phase and are expected to be operational by 2025, as there are currently no operational municipal insurance pools for climate hazards in developing countries.
• Common barriers to financial aggregation include a lack of municipal borrowing authority, high operational costs for developing green frameworks, and the risk that long-term political commitments may wane due to election cycles.
