New Resilience Taxonomy Brings Clarity to Climate Risk in the $4.3 Trillion Municipal Bond Market

HOOD RIVER, Ore.–(BUSINESS WIRE)–#AssetManagement–As U.S. cities face increased exposure to climate-driven physical risks, Kestrel, the leader in Sustainability Intelligence, today released its Resilience Taxonomy for U.S. Infrastructure. (https://kestrelesg.com/wp-content/uploads/2026/01/Kestrel-Resilience-Taxonomy-for-US-Infrastructure.pdf) This framework provides the first standardized “best practices” for benchmarking resilience in the $4.3 trillion municipal bond market.

A Confluence of Risk and Opportunity

The release comes at a critical economic juncture defined by three intersecting trends. First, U.S. infrastructure faces climate-driven physical risks that threaten asset valuations. Second, municipal bond issuance to finance infrastructure is projected to reach record levels in 2026, with roughly $600 billion in new bonds. Finally, research from the World Resources Institute indicates every $1 invested in climate resilience can yield up to $10 in economic benefits. Kestrel’s taxonomy provides essential information to navigate this high-stakes environment, ensuring capital is directed toward infrastructure designed for long-term resilience.

Bridging the “Resilience Transparency” Gap

Kestrel’s new taxonomy reflects insights from benchmarking over 15,000 series of municipal bonds representing over $3 trillion in par amount. The taxonomy is designed to help investors identify issuers taking proactive steps to protect capital by identifying where resilience strategies are integrated into long-term planning. This is especially relevant for holders of broad-market instruments such as the State Street^® Nuveen Municipal Bond ESG ETF (MBNE), where granular insights into resilience are increasingly central to evaluating and protecting asset valuations.

“As the market’s expectations for resilience sharpen, we aim to lead with clarity,” said Monica Reid, CEO of Kestrel. “Resilience protects financial performance by reducing costly disruptions and strengthens overall market stability. It is fiscally responsible, non-partisan, and central to long-term value creation.”

Key Highlights from the Taxonomy:

• Material Resilience Indicators: Pinpoints specific features such as vehicle-to-grid charging for K-12 schools, undergrounding power lines for electric utilities, and flood elevation design that are increasingly relevant to an asset’s long-term credit profile.
• Standardized Data Architecture: Kestrel Sustainability Intelligence replaces fragmented issuer disclosures with a systematic, decision-ready dataset, allowing market participants to seamlessly identify bonds that meet sustainability and resilience criteria and align with global standards.
