The Network for Greening the Financial System (NGFS) and the Coalition of Finance Ministers for Climate Action (CFMCA) have launched a joint dialogue platform to deepen knowledge sharing between central banks and finance ministries on the macroeconomic implications of climate change and the transition to a low-carbon economy. Announced on the margins of COP30 in Belém, the platform will convene senior fiscal and monetary officials for regular, informal exchanges on how climate and nature-related developments are affecting macroeconomic conditions, inflation, debt sustainability, financial stability, investment needs, and growth prospects. The series is positioned as a way to share approaches and support more coherent macroeconomic planning for the transition, while respecting the distinct mandates and independence of central banks. The launch event at the Sustainable Innovation Forum in São Paulo was the first in a series of roundtables, with thematic dialogues planned over the course of 2026, hosted by participating institutions and structured around key macroeconomic dimensions of climate change and a resilient low-carbon transition, including case studies and moderated discussion.
