Climate Solutions Week 2026

Overview

The Climate Solutions Week 2026 took place in Vienna on April 7–9, 2026, hosted by the OPEC Fund for International Development, to advance practical, finance-ready climate solutions at the water, adaptation and nature nexus. A key milestone was a high-level water roundtable co-organized with the World Bank on April 7, which brought together multilateral development banks, development finance institutions, philanthropy and governments.

Climate Solutions Week brought together key partners to align on priorities and resilience financing through plenaries, closed-door roundtables and targeted working sessions.
