Green bonds and sustainability bonds are fixed-income instruments used to raise capital specifically for environmental and ESG projects. The green bond market has grown exponentially, becoming a major source of climate finance.

What Are Green Bonds?

Green bonds are debt securities where:

1. Proceeds are designated for green projects
2. Issuer commits to transparency on use of proceeds
3. External review validates green credentials

Key Characteristics

• Project selection: Defined by green bond framework
• Tracking: Issuer monitors and reports on allocation
• Impact reporting: Discloses environmental outcomes
