Channelling trillions into climate solutions

Climate Bonds is an international organisation working to mobilise global capital for climate action and resilience, ensuring investments support a sustainable, adaptive, and low-carbon future.

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.

By the end of 2025, Climate Bonds had recorded USD 8.1 trillion in cumulative GSS and SLB issuance (GSS+), of which USD 6.8 trillion, or 83%, was assessed as aligned with Climate Bonds methodologies. This reflects strong and sustained market growth, while also highlighting the importance of rigorous, science-based screening in ensuring credibility and transparency.
