Sustainable Debt Global State of the Market H1 2026

Aligned GSS+ volume breaks USD7tn cumulative as green issuance hits a record quarter.

By the end of June 2026, Climate Bonds had recorded USD7.3tn in cumulative aligned green, social, sustainability and sustainability-linked (GSS+) debt — another trillion-dollar milestone, and 83% of the USD8.8tn in total GSS+ volume Climate Bonds has tracked since 2006.

In the first half of 2026 alone, aligned GSS+ issuance reached USD529.7bn, powered by the third-strongest quarter on record (USD288.5bn in Q2). That's broadly flat on H1 2025 (-1% like-for-like), with USD257.1bn in maturities leaving the market USD272.6bn larger and an outstanding aligned volume of USD5.4tn.
