Identifying a New Approach to Triple Urban Climate Finance

The Global SDSN Commission for Urban SDG Finance’s first member-only forum of 2026, held under Chatham House Rule, provided space to discuss the latest insights from leading urban finance experts.

The Global SDSN Commission for Urban SDG Finance convened its first thematic forum of 2026 on February 27 to thoroughly examine what the global commitment to triple adaptation finance by 2035 means in practical terms for cities. The session under Chatham House rule brought together Commission members and expert contributors for a candid and productive discussion.

Participants reached a consensus that scaling adaptation finance must move beyond ambitious commitments to ensure tangible, accessible funding for subnational governments, particularly in rapidly urbanizing regions. A core takeaway was that increasing finance volumes must be paired with fundamental reforms to how finance is allocated, structured, and delivered. This includes strengthening the fiscal fundamentals of cities through predictable multi-year public finance, improved local fiscal capacity, stronger data systems, and institutional readiness.

The discussion highlighted several critical areas for reform within the global financial architecture. Improving coordination among development finance institutions (DFIs) was identified as essential to reduce fragmentation, align investment pipelines, and accelerate project delivery at the city level. Several participants also emphasized the need to examine the portfolio composition and incentive structures within DFIs to ensure that adaptation and mitigation considerations are systematically embedded in mainstream infrastructure and urban finance, rather than treated as separate categories.

Scaling investment will also require a greater focus on subnational transaction architecture. This includes developing project preparation hubs, city-bundling mechanisms, and enabling structures to mobilize private capital for urban adaptation projects.

Flood resilience emerged as a particularly urgent need across many urban contexts. Nature-based solutions and integrated land-use and infrastructure planning were highlighted as cost-effective approaches to managing flood risk while simultaneously delivering broader resilience and environmental benefits.

The forum reinforced the Commission’s vital role in articulating a clear, cohesive urban perspective within global climate finance debates. The insights gained will directly inform the Commission’s advocacy priorities for 2026, focusing on enabling reforms, improved institutional coordination, and stronger support systems that allow cities to effectively access and deploy adaptation finance.
