Sustainable Debt Global State of the Market 2020

The global sustainable debt market reached USD 1.7 trillion by the end of 2020, with USD 700 billion issued during the year. While green bonds remain the largest segment, social and sustainability bonds saw dramatic growth in 2020, largely driven by pandemic-related funding. The European Union has emerged as a global leader, integrating GSS bonds into its climate neutrality goals for 2050 and developing comprehensive taxonomies and standards to ensure market integrity.

• The total sustainable debt market reached USD 1.7 trillion by the end of 2020, with USD 700 billion issued in 2020 alone, nearly double the USD 358 billion issued in 2019.
• The social bond market experienced a more than 10-fold increase (1017%) year-on-year in 2020, primarily due to the COVID-19 pandemic. Pandemic-labelled bonds accounted for 34% of all social bond issuance in 2020.
• Green bond issuance reached a record USD 290.1 billion by the end of December 2020, with the Climate Bonds Green Bond Database hitting a cumulative USD 1 trillion milestone in early December.
• Sustainability bond issuance grew by 131% in 2020, with supranational issuers (SNAT) accounting for 63% of the volume, largely driven by the World Bank which issued USD 81 billion.
• The European Union is the largest issuer of GSS bonds and aims to be the first climate-neutral bloc by 2050. It has linked its budget to green policy, including the European Green Deal, and is developing the EU Taxonomy to standardize environmentally sustainable investments.
• Sovereign GSS bond issuance reached USD 97.7 billion from 22 sources by the end of 2020. These bonds are noted for catalysing local markets, increasing transparency through budget tagging, and diversifying investor bases.
• Transition finance is emerging to include emissions-intensive sectors like mining, steel, and cement. By the end of 2020, 11 bonds had been issued with a transition label.
• The European Central Bank (ECB) supports the GSS market by including such bonds in its quantitative easing programmes (APP and PEPP) and has established a Climate Change Centre to incorporate climate considerations into its work.
