The Green Bond Transparency Platform (GBTP) is an initiative developed by the Inter-American Development Bank (IDB) to strengthen transparency, credibility and investment in Green, Social and Sustainability (GSS+) bond markets across Latin America and the Caribbean (LAC).
The platform supports the harmonization and standardization of bond reporting, enabling issuers to disclose the use of proceeds and environmental and social impacts in a consistent and comparable manner. The GBTP is free of charge and serves as a benchmark for best-practice disclosure, offering practical support to all market participants:

- Issuers: a simple, standardized format to report on the use of proceeds and impacts of their bonds.
- External reviewers: a clear and structured way to present pre- and post-issuance reviews and their conclusions.
- Investors: access to credible, comparable data to support evidence-based investment decisions.
- Public sector authorities: an evidence-based data tool to inform discussions on taxonomies, standards and market development.

By improving data availability and market visibility, the GBTP contributes to the development, integrity and credibility of sustainable bond markets in the region.
