The Climate Bonds Social and Sustainability Bond Dataset Methodology (2025) outlines the criteria and screening processes used by the Climate Bonds Initiative to identify and classify credible social and sustainability (S&S) bonds.

This report by the Climate Bonds Initiative analyzes the alignment of green, social, and sustainability bonds priced in the first nine months of 2022 with its database standards. While most issuance meets these criteria, a significant portion of labelled debt is excluded due to insufficient disclosure or a lack of ambition in the Use of Proceeds (UoP).

The Climate Bonds Initiative (CBI) Social and Sustainability Bond Database (SSBDB) Methodology outlines the criteria and process for identifying and classifying social and sustainability-labelled debt instruments. The database aims to provide transparency on global social and sustainability debt, including use-of-proceeds (UoP) bonds and sustainability-linked bonds (SLBs), while ensuring these instruments do not cause significant harm to climate change mitigation and adaptation.
