The ambitious renewable energy targets pledged by India under the Paris Agreement, adopted in Paris, France, on December 12, 2015, envisage the installation of 500 GW of renewable energy capacity by 2030. Achieving such an ambitious target requires a steady flow of financial resources, a need that has been significantly supported by the increasing issuance of green bonds in the country.
Green bonds are among the most sought-after fixed-income debt instruments for financing renewable energy projects in India. According to a report published by the Press Information Bureau (PIB), as of January 2026, the Government of India had issued sovereign green bonds worth ₹15,000 crore during FY26, taking the cumulative issuance since FY23 to ₹72,697 crore. India’s green bond market is largely dominated by private-sector and corporate issuers, accounting for approximately 84% of cumulative issuances. In 2015, Yes Bank launched India’s first green bond, raising ₹1,000 crore to finance renewable energy and clean transportation projects.
The Government of India issued its first sovereign green bond in 2023, with the Reserve Bank of India (RBI) auctioning ₹16,000 crore across two tranches in January and February to finance public-sector projects aimed at reducing the economy’s carbon intensity, including renewable energy and clean transportation initiatives. Municipal green bonds have also gained prominence over the last decade, with the Ghaziabad Municipal Corporation in Uttar Pradesh becoming India’s first municipal body to issue a green bond, raising ₹150 crore for the development of a tertiary sewage treatment plant.
Driven by India’s commitment to achieving net-zero emissions by 2070, and with Grand View Research Inc. projecting the country’s sustainable finance market to reach USD 70.9 billion by 2030, expanding at a robust compound annual growth rate (CAGR) of 29.5% between 2025 and 2030, the green bond market is expected to witness significant growth in the coming years. Supported by recent regulatory frameworks introduced by the SEBI and the RBI, India has generated approximately USD 110 billion in green revenues, outpacing overall green growth across Asia.
In India, the green bond market is primarily regulated by the Securities and Exchange Board of India (SEBI) through its regulatory framework for green debt securities, while sovereign green bonds are issued under the Government of India’s Sovereign Green Bond Framework. These frameworks are broadly aligned with the International Capital Market Association’s (ICMA) Green Bond Principles and are periodically updated to reflect evolving environmental, social, and governance (ESG) standards. Despite the rapid growth of the market, several significant bottlenecks continue to hinder the seamless flow of investments, primarily due to structural and regulatory challenges.
One major challenge is the shrinking green premium, commonly referred to as the greenium, in India. Greenium is the pricing advantage enjoyed by issuers when green bonds are traded at higher prices than conventional bonds because investors are willing to pay a premium for environmentally sustainable investments while accepting lower yields. In developed economies such as the United States, Europe, and Japan, the average greenium ranges between 2 and 4 basis points, whereas in emerging markets it has historically averaged 11 to 13 basis points. However, in India, despite being an emerging economy, the average greenium remains significantly below the global emerging market average, with most issuances recording negligible or near-zero greenium.
The limited pricing advantage can largely be attributed to structural constraints within the Indian economy, including a narrow domestic investor base and the absence of a comprehensive national green taxonomy. Unlike developed markets, domestic institutional investors in India, including insurance companies, provident funds, and mutual funds, generally lack formal ESG investment mandates. Their investment decisions are driven primarily by yield, liquidity, and credit ratings rather than environmental impact.
Furthermore, in the absence of a comprehensive statutory national green taxonomy, uncertainty persists regarding what genuinely qualifies as a “green” project. This ambiguity creates uncertainty for both domestic and international investors, who rely on clear, internationally aligned definitions to assess the environmental credibility of green bonds. Without a unified taxonomy for climate finance, the classification of green activities remains fragmented, with different regulatory bodies issuing their own standards. For instance, the RBI introduced its Framework for Acceptance of Green Deposits in 2023, while the Government of India introduced the Sovereign Green Bond Framework in 2022, each defining eligible green sectors independently.
As highlighted by experts, merely developing a taxonomy will not be sufficient. “It is very important to make sure that all the stakeholders follow the taxonomy in letter and spirit,” says Tandon from NIPFP. “Ultimately, all the stakeholders have to align with the taxonomy through credible disclosures,” adds Kumar from the Climate Bonds Initiative (CBI). Such alignment would facilitate smoother financial flows by creating a common language for sustainable finance through a unified taxonomy and disclosure regime. Kumar further emphasises that a well-designed taxonomy would bridge an important gap in India’s rapidly evolving sustainable finance ecosystem.
A comparative analysis of India’s green bond market with that of China, the world’s third-largest issuer of green bonds, with issuances amounting to USD 20.7 billion in the first quarter of 2025, illustrates the benefits of a proactive and cohesive regulatory strategy. China’s Green Finance Taxonomy has consolidated multiple regulatory frameworks into a unified classification applicable to both loans and bonds, thereby increasing investor confidence and reducing the cost of identifying eligible projects.
In contrast, India’s current regulatory landscape remains fragmented. Initiatives such as the Green Deposit Framework and the Sovereign Green Bond Framework continue to operate independently without an overarching statutory green finance taxonomy. This fragmented approach increases the risk of greenwashing while simultaneously reducing investor confidence.
In conclusion, India stands at a critical juncture in the development of its green finance market. The country’s ambitious renewable energy targets, growing green bond issuances, and commitment to achieving a net-zero economy demonstrate strong policy intent. However, significant challenges remain. The continued decline in greenium and the absence of a unified regulatory framework reveal a gap between policy ambition and implementation. China’s experience clearly demonstrates that without a comprehensive national green taxonomy, India’s sustainable finance aspirations may fall short of their full potential.
As experts have rightly observed, creating a taxonomy is only the first step; ensuring its widespread adoption is equally important. To successfully achieve its renewable energy and climate goals, India must move beyond establishing regulatory frameworks and create an ecosystem in which environmental value is priced as efficiently as credit risk. This will require coordinated efforts by regulators, issuers, investors, and other stakeholders to adopt a common and transparent approach to green finance.
