Green finance refers to any structured financial activity—including loans, debt instruments, and investments—specifically designed to yield positive environmental outcomes. It serves as the financial engine for a transition toward a low-carbon, resource-efficient, and sustainable economy.
Conceptual Clarity and Definitions
- Green Finance: Broadly covers financing for environmental objectives like pollution control, biodiversity, and renewable energy.
- Climate Finance: A subset of green finance specifically focused on Climate Change Mitigation (reducing emissions) and Climate Adaptation (building resilience against climate impacts).
- Sustainable Finance: The broadest category, which integrates ESG (Environmental, Social, and Governance) criteria into investment decisions.
Key Green Finance Instruments
The mobilization of capital occurs through specialized financial products:
| Instrument | Description |
| Green Bonds | Fixed-income instruments where proceeds are earmarked for green projects (e.g., solar parks). |
| Green Deposits | Fixed deposits where banks pledge to invest the proceeds only in eco-friendly sectors. |
| Sustainability-Linked Loans | Loans where the interest rate is linked to the borrower achieving specific environmental KPIs. |
| Green Masala Bonds | Rupee-denominated bonds issued in international markets to fund local green projects. |
| Carbon Finance | Financial resources provided to projects that generate tradeable carbon offsets or credits. |
Global Institutional Framework
International mechanisms under the UNFCCC and the Paris Agreement facilitate the flow of funds from developed to developing nations:
- Green Climate Fund (GCF): The world’s largest dedicated fund helping developing countries reduce their greenhouse gas emissions.
- Global Environment Facility (GEF): Operates as a financial mechanism for five major international environmental conventions, including the Minamata Convention on Mercury.
- Adaptation Fund (AF): Specifically finances projects that help vulnerable communities in developing countries adapt to climate change.
- Green Bond Principles (GBP): Voluntary process guidelines issued by the International Capital Market Association (ICMA) to promote transparency and integrity in the bond market.
Green Finance Landscape in India
India requires an estimated $2.5 trillion between 2015 and 2030 to meet its targets under the Paris Agreement.
Regulatory Milestones
- RBI’s Green Deposit Framework (2023): Regulated Entities (REs) must have a board-approved policy to accept green deposits and provide third-party verification on the use of funds.
- SEBI’s BRSR Core (2024-2025): The Business Responsibility and Sustainability Reporting (BRSR) framework was made mandatory for the top 1,000 listed entities. From FY 2025-26, the top 250 entities must perform “Value Chain Reporting.”
- Sovereign Green Bonds (SGrBs): The Government of India issued its first SGrB in early 2023. These bonds are part of the government’s overall market borrowings and are used for “Green Infrastructure.”
Sovereign Green Bond Framework Features
- Eligible Sectors: Renewable energy, energy efficiency, clean transportation, water and waste management, and green buildings.
- Excluded Sectors: Nuclear power generation, large hydropower (over 25 MW), and any projects related to fossil fuels.
- Greenium: This refers to the “Green Premium”—the lower yield (and thus lower cost of borrowing) that investors accept for green bonds compared to conventional bonds.
Major Challenges and Bottlenecks
Despite rapid growth, several hurdles persist in the Indian green finance ecosystem:
- Greenwashing: The practice of making misleading claims about the environmental benefits of a product or project to attract “green” capital.
- Lack of Taxonomy: India currently lacks a formal “Green Taxonomy”—a standardized system of classification that defines what exactly constitutes a “green” investment.
- Information Asymmetry: High costs associated with the monitoring, reporting, and verification (MRV) of green projects.
- Asset-Liability Mismatch: Green projects (like offshore wind) often have long gestation periods, whereas commercial bank loans are typically short-to-medium term.
- High Cost of Capital: Foreign currency fluctuations increase the cost of “Green Masala Bonds” for Indian issuers.
