Green and Social Bonds

The thematic bonds market (Green, Social, Sustainability, Sustainability-Linked) is one of the fastest growing segments of fixed income. Issuance volume in 2023 exceeded $900 billion per year, and the total outstanding market is over $4 trillion.

Green Bonds

Definition

Debt instruments where the raised funds are directed exclusively to finance projects with environmental benefits.

Eligible Categories (ICMA Green Bond Principles)

• Renewable energy (wind, solar, hydro)
• Energy efficiency in buildings and industry
• Clean transport (EV, public transportation)
• Water resource management
• Sustainable land use and reforestation
• Climate change adaptation
• Green buildings (LEED, BREEAM certification)

Structure

Use of Proceeds: The issuer is obligated to allocate funds only to eligible projects. Separate accounting is maintained (ring-fencing).

Project Evaluation: Description of the project selection process, ESG criteria.

Management of Proceeds: How the funds are kept until use (separate account, sub-portfolio).

Reporting: Annual report on the use of proceeds and environmental impact (tons of CO₂, MW of installed capacity).

Second Party Opinion (SPO): An independent verifier (Sustainalytics, Vigeo Eiris) confirms compliance with standards.

Greenium

Green bonds usually trade with a greenium—that is, slightly lower yield (higher price) compared to conventional bonds from the same issuer. Magnitude: on average 1–10 bps.

Reasons for greenium:

• Increased demand from ESG-mandate investors
• Limited supply of quality issues
• Signaling effect (management quality)

Largest Issuers

• Sovereigns: Germany, France, Netherlands, Japan, Saudi Arabia (!) — first green sukuk
• Supranationals: EIB, World Bank, KfW
• Corporations: Apple, Volkswagen, HSBC, Iberdrola
• UAE: Dubai government, DP World, Masdar

Social Bonds

Funds are directed to socially significant projects:

• Affordable housing
• Access to basic services (healthcare, education, water)
• Employment and microfinancing
• Food security
• Socio-economic programs for vulnerable groups

Example: IFC Social Bond → financing MFIs in developing countries → loans to small businesses managed by women.

Sustainability Bonds

Combination of Green + Social: funds may be allocated to both environmental and social projects.

Sustainability-Linked Bonds (SLB)

Key difference from Green Bonds: Proceeds do not have designated use (general corporate purposes). Instead, financial conditions of the policy are tied to achieving ESG targets.

Mechanics:

• The issuer sets KPIs (e.g., reducing Scope 1 emissions by 30% by 2030)
• If the KPI is not met → coupon step-up (usually +25–50 bps)
• If met → coupon remains unchanged

Critique of SLB:

• KPIs are often weak and nearly achieved at the time of issuance
• Step-up penalty is too small → no real incentive
• Absence of ring-fencing of proceeds → greenwashing risk
• EU Taxonomy is tightening requirements

Investment Strategy for FO

When including green bonds in a portfolio:

1. Assess real ESG additionality (not all "green" bonds are equally green)
2. Analyze SPO and reporting quality
3. Account for greenium—impact on yield
4. Diversification: not only "dark green" (pure renewables), but also transition bonds (carbon-intensive sectors in decarbonization process)
5. Currency risk: a significant part of the market is in EUR and USD
