Setting the Green Standard
Climate Bonds screens self-labelled green bonds against a science-based methodology to ensure they align with climate goals, environmental impact, and minimum safeguards, creating a robust and practical Standard for market integrity. The green bond market continues to grow, with stronger alignment driving more credible labelled issuance.
As of the end of 2025, Climate Bonds had recorded USD8.1tn of cumulative GSS and SLB (collectively GSS+) volume, of which USD6.8tn (83%) was found to be Climate Bonds aligned.
This indicates strong appetite for thematic debt, with the difference between the two numbers highlighting the rigour of Climate Bonds curation.
