Sustainable Debt Global State of the Market Q1 2026

The Climate Bonds Initiative's Q1 2026 report details the state of the global aligned GSS+ (Green, Social, Sustainability, and Sustainability-linked) debt market. As of March 2026, the cumulative aligned volume reached USD 6,986.0 billion, with green-labelled debt remaining the dominant theme. While the overall market saw a 9% decline in supply compared to Q1 2025 on a like-for-like basis, specific regions like France and Germany showed strong activity in social and green bonds, respectively.

• As of the end of March 2026, the cumulative aligned volume of GSS+ debt reached USD 6,986.0 billion, which represents 83% of the total GSS+ volume of USD 8.4 trillion recorded by Climate Bonds.
• In Q1 2026, aligned GSS+ debt instruments totaled USD 230.3 billion, marking a 9% decline from Q1 2025 when using a like-for-like comparison that excludes certain US issuers.
• Green-labelled debt continues to lead the market, accounting for 65% of Q1 2026 aligned GSS+ volume at USD 150.2 billion, and 62% of the cumulative aligned volume at USD 4.3 trillion.
• Germany experienced its most prolific quarter for green debt in Q1 2026, pricing USD 30.9 billion. This was driven by the German sovereign (USD 7.6 billion) and the state-owned development bank KfW (USD 7.2 billion).
• France was a significant contributor to aligned social volume in Q1 2026, pricing USD 18.5 billion. The majority of this (USD 17.6 billion) came from government-backed entities, with Caisse d’Amortissement de la Dette Sociale (CADES) leading with USD 11.8 billion.
• The sustainability label saw a sharp decline in Q1 2026, recording its slowest first quarter since 2020 with USD 34.2 billion in aligned volume. This was largely due to a drop in supply from development banks, specifically the International Bank for Reconstruction and Development (IBRD), which fell from USD 22.4 billion in Q1 2025 to USD 4.8 billion in Q1 2026.
• Aligned Sustainability-linked bond (SLB) volume in Q1 2026 was USD 3.0 billion, a slight increase from USD 2.6 billion in Q1 2025. This volume represents 53% of the total SLB volume issued during the quarter.
• Sovereign aligned volume in Q1 2026 was USD 38.0 billion, a 7% increase from Q1 2025. European sovereigns dominated the space, with Austria recording a record quarterly volume of USD 8.2 billion.
