What Are Green Bonds?
Green bonds are debt instruments issued by governments, corporations, or institutions to raise money exclusively for environmental projects. Unlike traditional bonds, they follow strict guidelines:
- Proceeds must fund initiatives like solar farms, energy-efficient buildings, or pollution control.
- Third-party auditors (e.g., Climate Bonds Initiative) verify projects meet sustainability criteria.
- Transparency reports track progress, ensuring accountability.
Example: The European Union’s €250 billion green bond program funds wind energy and hydrogen infrastructure.
Key Benefits of Green Bonds
- Competitive Returns: Similar yields to traditional bonds (2–5% average).
- Portfolio Diversification: Low correlation with volatile stocks.
- Tax Incentives: Some regions offer tax-exempt interest income.
- Ethical Impact: Directly reduce carbon footprints.
