"""""""""""""""" Cities Climate Finance Leadership Alliance

Guarantees are a powerful credit-enhancement tool that can provide investors with the ability to leverage more capital to address social and environmental challenges. Lowering the risk profile of investment to decrease the cost of infrastructure project finance: city governments can ensure the infrastructure project against commercial, political and environmental risks or reduce the interest rates through credit enhancements and guarantees. Different international organisations provide credit enhancement and guarantee instruments. One example is subordinated debt, often provided as convertible loans (mezzanine finance). Another example is credit guarantees by multi-lateral development banks, for instance, to national financial institutions, that can provide credit enhancement to infrastructure project bonds, which in turn achieve a higher credit rating and can thus mobilise cheaper money from investors with mandated lower risk profiles, such as insurance or pension funds.
