Sustainable Debt Market Surges as Social Bonds Overtake Green
The global sustainable debt market is booming, signaling a growing investor appetite for investments aimed at addressing climate change and other social challenges.
Recent data from the Climate Bonds Initiative (CBI) reveals a robust and diversifying market, exceeding projections and setting the stage for trillions of dollars in sustainable investments.
This year got off to a strong start, with January witnessing a record-breaking $81 billion in green bond issuances. That record was quickly surpassed in May, further highlighting the momentum in this sector. Preliminary data suggests that total green bond issuance for the year could surpass $720 billion, building on the approximately $630 billion already traded. If this rate continues, the global volume of green bonds in circulation could reach $3.5 trillion by year-end.
CBI’s most recent “Sustainable Debt Market Summary Q3 2024” report provides key insights into this burgeoning market. Notably, social bonds have now overtaken sustainable bonds, demonstrating a growing focus on addressing various social challenges alongside environmental concerns.
Social bonds surpassed the $1 trillion mark in the third quarter of 2024, reaching a total volume of $1.1 trillion. This impressive growth eclipses the sustainable bond category, which reached $956.4 billion in issuance by the end of the third quarter and is projected to reach $1 trillion for the full year.
Overall, from January to September 2024, over $5.4 trillion was recorded under GSS+ debt. The third quarter was the strongest quarter since 2021, with $248.7 billion in new issues, a 19% increase compared to the same period in 2023. Analyzing the issuance landscape reveals an increase in volume from non-financial companies, sovereigns, development banks, and government-backed entities in the third quarter.
Development banks led the surge in volume, recording a remarkable 120% increase in the third quarter of 2024, reaching $52.9 billion compared to $23.9 billion in the same period of 2023.
“The global market of sustainable debt is thriving and continues to offer new diversification opportunities for investors,” explains Caroline Harrison, Director of Technical Development at Climate Bonds. “COP29 highlighted the urgency of increasing financial flows for climate change solutions from billions to trillions, and the GSS+ market can achieve this goal. The standards, the infrastructure, and the appetite of investors are all in place to absorb the growth in scale required.”
A Green Wave in the Data Center Industry
The burgeoning data center market, fueled by the rapid advancement of artificial intelligence, is increasingly turning to green bonds for expansion. This trend is already well underway, particularly in the United States, with immense potential for growth as the global data center market is anticipated to reach $418 billion by 2030 and beyond.
Several U.S. data center operators have tapped into the green bond market in recent months. Notably, Stack Infrastructure emerged as the largest corporate issuer of CBI-aligned green debt, securing a $3 billion loan last August. Another major player, Digital Realty Trust Inc., a Texas-based global data center provider, listed a $942 million, nine-year green bond through its subsidiary, Digital Dutch Finco BV, in September. This marks Digital Realty’s seventh green bond issuance since 2015, further solidifying its commitment to sustainable growth. The company recently completed the allocation process for its other six sustainable operations, which support over 130 projects with a combined volume of $6 billion.
