Green Bonds are fixed-income financial instruments specifically designed to raise capital for projects with positive environmental or climate benefits. While they function like traditional bonds—where an investor loans money to an entity for a defined period at a fixed interest rate—the distinguishing factor is the “Use of Proceeds,” which is exclusively earmarked for “green” projects such as renewable energy, clean transportation, and sustainable water management.
Evolution and Global Context
- First Issuance: The World Bank issued the first official green bond in 2008.
- Global Standards: The International Capital Market Association (ICMA) established the Green Bond Principles (GBP), which provide the voluntary framework for transparency, disclosure, and reporting.
- The “Greenium”: This refers to the Green Premium, where investors accept a slightly lower yield (return) on green bonds compared to conventional bonds because of the added environmental value and lower long-term risk profile.
Sovereign Green Bonds (SGrB) in India
India entered the sovereign green bond market to fund its transition toward a low-carbon economy and meet its Nationally Determined Contributions (NDCs).
Framework and Governance
- Launch: The Government of India (GoI) published its Sovereign Green Bond Framework in November 2022.
- Governance: A Green Finance Working Committee (GFWC), chaired by the Chief Economic Adviser, selects and evaluates eligible projects.
- Target Areas: Projects are categorized under sectors like Renewable Energy, Energy Efficiency, Clean Transportation, Climate Change Adaptation, and Sustainable Water & Waste Management.
- Exclusions: Projects involving fossil fuels, nuclear energy, or large hydropower (above 25 MW) are strictly excluded from the “green” eligibility list.

SEBI’s ESG Debt Securities Framework
The Securities and Exchange Board of India (SEBI) regulates the private and municipal green bond market. In June 2025, SEBI expanded the definition of green debt securities into a broader ESG (Environmental, Social, and Governance) framework.
- Expanded Categories: Now includes Social Bonds, Sustainability Bonds, and Sustainability-Linked Bonds.
- BRSR Linkage: Issuers must align disclosures with the Business Responsibility and Sustainability Reporting (BRSR) core framework.
- External Review: Mandatory third-party transition audits or reviews are required to prevent Greenwashing (the practice of making misleading claims about environmental benefits).
Strategic Significance and Trivia
Greenwashing and Integrity
Greenwashing is the biggest challenge to the green bond market. To counter this, India’s framework follows the “Avoidance, Reduction, and Removal” principle and requires annual reporting on the environmental impact (e.g., CO2 emissions avoided).
Municipal Green Bonds
Several Indian cities have pioneered the use of green bonds for local infrastructure:
- Indore: Issued India’s first municipal green bond for a solar power project.
- Ghaziabad: Issued a green bond for a tertiary water treatment plant.
- Vadodara and Ahmedabad: Have successfully utilized SEBI’s framework for climate-aligned urban functions.
Key Comparisons: Green vs. Conventional Bonds
- Primary Difference: Earmarking of funds; conventional bonds can fund any general government expenditure (e.g., salaries, subsidies), whereas green bond proceeds are legally ring-fenced for specific projects.
- Reporting: Green bonds require intensive “Impact Reporting” and “Allocation Reporting,” whereas conventional bonds do not.
- Investor Base: Green bonds attract specific “Impact Investors” and ESG-focused funds that might not otherwise invest in emerging market debt.
