Abstract
In recent years, credit ratings agencies have formally included metrics of climate and disaster risk in their municipal bond assessments. Although municipal bond ratings are a critically important element of local government finance with the power to motivate environmental and non-environmental policy, their entanglements with emergent climate and disaster risk, as well as responsive decision-making, are understudied. To better understand the potential implications of climate risk inclusions and to complement efforts focused on large cities, this exploratory effort places a new methodology through which Moody’s – one of the three primary ratings agencies – embeds climate and risk and resilience in their ordinal ratings categories into conversation with literatures on municipal finance, decision-making and bond ratings. By comparing the ratings treatment of Miami, a vulnerable but large and well-resourced municipality, with three smaller, less affluent bond issuers, it highlights some spatially uneven risks arising from ratings inclusions. Critically, it emphasises the internal diversity of bonds and issuers, a tension between long-term preventative investment to support resilience and adaptation and short-term crisis response, as well as several other ways that these factors may differentially impact local financial and environmental policy in smaller, less well-resourced municipalities that fly under the analytical radar.
