The global green bond market continues to show resilience with steady issuance expected in 2026, as the share of green and sustainable debt in corporate issuance has doubled since 2022.

Green Bond Issuance Trends: Steady Growth with Changing Composition
According to Moody’s 2026 outlook, global sustainable bond issuance is expected to remain steady in 2026. A significant trend is the changing composition of corporate debt; the share of green bonds and loans combined has increased from 34% in 2022 to 68% in 2025, a preference expected to continue. This indicates that while total issuance volumes may fluctuate, the prioritization of labeled sustainable instruments by corporates is firmly entrenched.
US State AGs Challenge ESG Rating Agencies Over Conflicts of Interest
The Nebraska Attorney General has issued a formal letter to major ratings agencies, arguing that their participation in initiatives like the UN PRI and Net-Zero Asset Managers creates material conflicts of interest. The letter suggests these commitments significantly alter the "total mix" of information provided to investors regarding agency neutrality. This legal and regulatory pressure highlights the growing political and legal friction facing ESG data providers in the United States.
Investors Demand Financial Substance Behind Net-Zero Pledges
Private equity Limited Partners (LPs) are increasingly treating climate risk as a core governance and financial risk question rather than a reputational one. According to FTI Consulting’s 2026 ESG survey, investors are actively asking whether investment committees consider climate risk during deal approval. When companies deflect these questions with PR language instead of hard data, it signals to the market that their transition story lacks solidity.
Green Capital Flows
-
Global Sustainable Bond Issuance: Moody's projects steady issuance levels for 2026, maintaining the momentum from the record $653.5 billion in green bond issuance seen in 2025. The market is maturing, with cumulative aligned GSS+ (Green, Social, Sustainability) debt exceeding $5.7 trillion.
-
Corporate Debt Composition: There is a distinct shift in capital structure preferences among corporates. Data indicates that green bonds and loans now constitute nearly 70% of total corporate sustainable debt issuance, up from roughly one-third in 2022. This suggests that "greenwashing" via simple labeling is being replaced by structural integration of sustainability into balance sheets.
Regulation & Policy Watch
-
Nebraska AG vs. Ratings Agencies: The Nebraska Attorney General is formally challenging the operational independence of major ESG rating agencies, citing their membership in climate coalitions as a conflict of interest. This could set a precedent for how ESG ratings are regulated or viewed legally across other US states.
-
SBTi Corporate Net-Zero Standard v2.0: The Science Based Targets initiative (SBTi) is finalizing its Corporate Net-Zero Standard v2.0. The new standard, which closed consultation recently, offers refined metrics for Scope 1, 2, and 3 emissions. Companies are advised to prepare for recertification under these stricter guidelines starting January 2026.
Corporate Moves
- Net-Zero Asset Managers (NZAM): The NZAM coalition has relaunched with a reduced US presence and a new commitment statement that notably removes explicit references to reaching net-zero by 2050. The group describes its new commitments as "relevant, practical, and globally inclusive," signaling a shift away from rigid, politically targeted timelines toward more flexible frameworks.
What to Watch Next Week
- SBTi Recertification Deadlines: Monitor announcements from major corporations regarding their transition to the SBTi v2.0 standards, particularly regarding Scope 3 emissions accounting.
- State-Level Legal Actions: Watch for responses from major ratings agencies (S&P, MSCI, etc.) to the Nebraska Attorney General's letter, which may trigger broader legal defenses or policy adjustments.
- Q3 Earnings Season ESG Disclosures: As Q3 earnings approach, pay close attention to how companies articulate their climate transition plans in response to increased investor scrutiny on financial materiality.
Reader Action Items
- Audit Your Data Providers: Review your reliance on ESG ratings. Be aware of potential conflicts of interest highlighted by recent legal challenges and consider cross-referencing with primary data sources.
- Scrutinize "Net-Zero" Claims: For private equity or direct investments, demand specific financial data showing how climate risks are integrated into deal approval committees, moving beyond high-level pledges.
- Review Bond Portfolios: With green bonds making up a larger share of corporate debt, ensure your fixed-income strategy accounts for the liquidity and pricing differences of labeled sustainable instruments versus conventional debt.
