Global green debt sales have soared to unprecedented levels this year, reaching $947 billion, despite headwinds in the form of climate policy rollbacks in both the United States and Europe. Investors have continued to flock to climate-focused investments, driven by rising demand for energy infrastructure and optimism fueled by developments in artificial intelligence (AI).

A Year of Contrasts: Green Investment Versus Policy Retreats

The record-breaking figures for green bond and loan issuance come in a year marked by significant political pushback on environmental policies. In the United States, President Donald Trump dismantled clean-energy subsidies and pro-fossil fuel policies prevailed, while Europe scaled back some of its stringent environmental rules due to concerns about economic growth and competitiveness.

Despite these regulatory challenges, the market for green investments expanded, underpinned by the growing demand for electricity - expected to rise by nearly 4% globally - as well as increased electrification and cooling needs driven by AI developments. Melissa Cheok, associate director for ESG investment research at Sustainable Fitch, noted the changing perception of green investments: "Green investments are increasingly becoming viewed as core infrastructure and industrial plays, not just niche ESG trades."

Regional Trends: Asia-Pacific Leads the Way

Asia-Pacific emerged as a strong performer in green debt markets, with companies and government-linked issuers in the region raising $261 billion, a 20% increase from the previous year. China led the charge with $138 billion in green bond issuance, bolstered by significant contributions from its largest lenders. The country showcased its growing commitment to green finance by debuting a sovereign green bond offering in London earlier this year.

India also stood out as a key player in renewable energy funding, with 11 renewable energy IPOs raising over $1 billion, alongside record green loan volumes of $7 billion. However, increased competition from foreign banks has tightened financing margins for renewable projects, according to Jeanne Soh, head of structured finance for Asia at Sumitomo Mitsui Banking Corp.

The so-called "greenium", which refers to the lower borrowing costs associated with green bonds, was particularly evident in the Asia-Pacific region. BloombergNEF data from November revealed that some issuers in the region benefited from discounts exceeding 14 basis points for utilizing green labels.

Market Dynamics and Growth Expectations

In contrast to the overall growth in green debt issuance, the United States experienced a 7% decline, bringing its total to $163 billion. Supranational bond sales decreased by a similar percentage, while Germany maintained steady fundraising levels at approximately $79 billion. Meanwhile, global sales of sustainability-linked debt plummeted by about 50% to $165 billion, and transition bond issuance dropped by more than half to $10.9 billion amid concerns about greenwashing.

However, the broader momentum in green markets appears resilient. BNP Paribas SA and Credit Agricole SA emerged as the leading underwriters of green bonds this year. Researchers from LSE Group noted that outstanding green bonds have grown at a compound annual rate of 30% over the past five years, now making up about 4.3% of global debt issuance. Looking ahead, easing US interest rates and refinancing needs could propel global green bond sales to as high as $1.6 trillion next year, according to Crystal Geng, ESG research lead for Asia at BNP Paribas Asset Management.

Sector Highlights and Stock Market Gains

Renewable energy stocks outperformed broader markets this year, with clean-energy indexes from S&P Dow Jones Indices and WilderShares surging by 45% and 60%, respectively, though both remain below their 2021 peaks. Solar and battery storage companies in the US, including SolarEdge Technologies Inc., delivered standout performances, while wind turbine manufacturers in China and Germany also posted significant gains.

India's renewable energy sector continued to be a hotspot for IPO activity, with six additional companies seeking to raise over $3 billion after an already robust year of fundraising.

Challenges and Opportunities Ahead

As the landscape evolves, some trends suggest a potential reversal of this year’s setbacks in sustainable debt markets. Xuan Sheng Ou Yong, a client portfolio manager for sustainable investing at Robeco in Singapore, highlighted that upcoming changes to European fund rules could redefine what qualifies as sustainable investment. This shift is expected to open new opportunities for emissions-reduction projects, even in higher-polluting sectors.

Despite some challenges, investor enthusiasm for green financing remains robust. As Cheok observed, areas like grid upgrades and renewables tied to electrification are particularly attractive due to their "clear revenue visibility, policy backing and structural demand."

Overall, global sustainable debt volumes reached $1.6 trillion this year, though this marked a decline of over 8% from the previous year. Meanwhile, social bonds in the US tied to the Government National Mortgage Association accounted for more than $500 billion in issuance, underscoring the breadth of the sustainable finance market.

The record-breaking green debt figures highlight the continued alignment of economic incentives and environmental priorities, even as policymakers in key markets grapple with balancing climate commitments and economic pressures.
