Fernando Rodríguez | Spanish issuers are becoming increasingly active in the global sustainable finance market. State-owned Instituto de Crédito Oficial (ICO) has joined the Nasdaq Sustainable Bond Network (NSBN), the platform that concentrates relevant information on sustainable bond issuers and transactions from all over the world with the aim of promoting transparency in this market. Iberdrola became the first issuer to join this platform in October last year, and BBVA was the first Spanish bank to do so a month later.
