Guidance Handbook
The Executive Committee of the Principles with the support of ICMA has published in June 2025 an updated edition of the Guidance Handbook.
Since the original publication of the Green Bond Principles (GBP) in 2014, and the subsequent releases of the Social Bond Principles (SBP) and Sustainability Bond Guidelines (SBG) in 2017, followed by the release of the Sustainability-Linked Bond Principles (SLBP) in 2020 (together, “the Principles”) as well as the Climate Transition Finance Handbook (CTFH) in 2020, market participants have sought additional information on how to interpret this guidance especially for its practical application for transactions, as well as in the context of market developments and complementary initiatives.
A new question has been introduced in the 2025 updated publication (2.1.15) related to GSS bonds and defence. Additional updates have been made to a few Q&As in the SLBs section with the aim (i) to ensure that the guidance is properly adapted for sovereign issuers and (ii) to review the definition of secondary KPIs.
The objective is that this publication be widely circulated and used by the GSSS Bond market. It is designed to support market development and to underpin market integrity.
