NATURANCE successfully generated knowledge underpinning nature-based insurance and investment solutions (NBIIS) and helped build convergence around their relevance, feasibility, and practical usefulness for climate adaptation. This document explains the steps we have taken to consolidate the project’s legacy and to contribute to the growing European landscape of climate adaptation, resilience finance, and Nature-based Solutions (NbS). Over the course of the project, we explored how insurance, investment, and disaster risk financing mechanisms can be combined with ecosystem restoration and NbS to reduce climate risks while generating environmental, social, and economic co benefits. Through nine innovation laboratories, four Festivals of Financial Innovation, numerous workshops, webinars, and extensive collaboration with Knowledge Networks, we co-developed shared design principles, performance metrics, business innovation cases, and governance approaches for NBIIS. A central element of the project legacy is standardisation. In NATURANCE we developed a CEN Workshop Agreement (CWA 18349:2026), which established the first pre-standardisation framework for NBIIS. The process brought together researchers, financial actors, public authorities, practitioners, and standardisation experts under the coordination of UNI (Italian Standardisation Body) and created pathways for future European and international standardisation activities. The project also strengthened links with the evolving European standardisation landscape on climate adaptation, climate services, and Nature based Solutions, including CEN/TC 465 and CEN/TC 467. We have also positioned NATURANCE within a wider ecosystem of Mission Adaptation, climate resilience, sustainable finance, and restoration initiatives. The project collaborated closely with flagship Horizon Europe projects such as CLIMAAX, PIISA, UNDERPIN, Invest4Nature, and Pathways2Resilience, while contributing to emerging initiatives linked to the Water Resilience Strategy and the EU Nature Credits Roadmap. Building on these partnerships, NATURANCE supported the preparation of new large-scale proposals and cascading funding schemes aimed at mobilising blended public private finance for adaptation and restoration investments across European regions. The project legacy is also grounded in long term capacity building and community development. NATURANCE established a durable “Network of Networks” connecting local and regional governments, researchers, insurers, investors, adaptation service providers, and NbS practitioners. Through this community, and through continued engagement in climate services, adaptation standardisation, and financing initiatives, the project’s principles, metrics, and business models are expected to continue shaping adaptation governance, resilience investments, and sustainable finance practices well beyond the project lifetime.
