The Sustainable Banking and Finance Network (SBFN) published an update on the Taxonomy Roadmap Initiative, announcing that the initiative, together with the Sustainable Business COP and the International Development Finance Club, will host a COP30 high-level event in Belém focused on improving interoperability and comparability of sustainable finance taxonomies to support transparency, cross-border investment and private capital mobilisation. Building on COP29 outcomes including a New Collective Quantified Goal to mobilize at least USD 1.3 trillion per year by 2035, the COP30 session “From Baku to Belém: Advancing Taxonomy Interoperability to Catalyse Private Capital Mobilization” is positioned as a forum for governments, development finance institutions and private-sector participants to discuss practical alignment solutions. The initiative plans to present a progress report on global taxonomy trends and best practices, high-level principles for taxonomy interoperability covering development and implementation, a Sustainable Finance Taxonomy Mapper digital tool to compare taxonomies across jurisdictions, and a dedicated website to share resources and coordinate implementation. These deliverables are expected to be showcased through the COP30 session and other COP30 events. The Taxonomy Roadmap Initiative is described as a voluntary multi-partner platform launched during COP29 and now including, among others, the Central Bank of Azerbaijan, International Finance Corporation, International Platform on Sustainable Finance, United Nations Development Programme, Deutsche Gesellschaft für Internationale Zusammenarbeit, United Nations Environment Programme Finance Initiative, Climate Bonds Initiative, the EU Sustainable Finance Advisory Hub, Principles for Responsible Investment and Brazil’s Ministry of Finance.
