One year after Banco Nacional Costa Rica’s inaugural blue bond, the first of its kind in the country, its impact is beginning to take shape far from financial markets — in the fields and water systems of Guanacaste. In one of the driest regions, where climate pressure and water scarcity threaten agricultural production, Azucarera El Viejo is showing what blue finance can achieve on the ground.
With bond-backed investments in water-saving technologies, treatment systems, and biodiversity measures, the company has cut water use by more than 30% while strengthening resilience, clean energy generation, and ecosystem protection. Its progress offers a compelling glimpse of how thematic bonds can drive measurable environmental change.
