Brazil Securities Commission (CVM), the Ibero-American Institute of Securities Markets (IIMV) and Spain's National Securities Market Commission (CNMV), with support from B3, held an event in São Paulo on how sustainable finance taxonomies can help mobilise capital for sustainable development, including a presentation of new Taxonomy Interoperability Principles. The interoperability principles were developed through a strategic collaboration between the Taskforce on Net Zero Policy, the Principles for Responsible Investment (PRI), the United Nations Environment Programme Finance Initiative (UNEP FI) and the Climate Bonds Initiative. In opening remarks, acting CVM president Otto Lobo pointed to CVM Resolution 193, which allows listed companies, investment funds and securitisation companies to voluntarily prepare and disclose sustainability-related financial information reports based on International Sustainability Standards Board (ISSB) standards IFRS S1 and IFRS S2. CVM director Marina Copola emphasised the role of the Brazilian Sustainable Taxonomy and the importance of objective, accessible criteria to simplify market use and help prevent greenwashing, while CVM superintendent Nathalie Vidual highlighted CVM’s participation in the Interinstitutional Committee of the Brazilian Sustainable Taxonomy (CITSB), which coordinates development and implementation of the Brazilian Sustainable Taxonomy (TSB). The event was held three days ahead of COP30, scheduled to take place in Belém from 10 to 21 November.
