As COP30 begins in Belém, transition plans are continuing to gain momentum as a critical tool for mobilising climate finance. This builds on the Co-chairs’ report of the G20 Sustainable Finance Working Group (SFWG), released in October, which set out robust recommendations for integrating adaptation into transition plans. Last week’s COP30 Business and Finance Forum in São Paulo marked a significant milestone with the launch of the latest Global State of Investor Climate Action.
