Costa Rica’s Sustainable Finance Taxonomy establishes for the first time a standardized definition of what constitutes an environmentally sustainable investment in the country. This framework provides a common language that enables financial sector actors and the real economy to identify investments aligned with national environmental and social objectives. Its development was led by public institutions such as MINAE, the Ministry of Finance, the Central Bank and the country’s financial superintendencies. It also involved the participation of more than 300 experts from over 180 organizations from the public and private sectors, academia, and nongovernmental organizations. The technical development was carried out by UNEP FI with funding from the Green Climate Fund and the European Union’s Euroclima Program.
