Evaluating the Environmental and Economic Effects of Green Bonds in India

Abstract

Green bonds have been issued for over a decade. Designed to fund projects with environmental benefits, they are expanding fast. However, few studies test their real impact in emerging economies like India, where industrial growth, energy demand, and climate risks converge. This study provides one of the first quantitative analyses of green bond issuance in India and its link to environmental and economic outcomes. Guided by the Environmental Kuznets Curve framework, this study examined whether green bond issuance aligns with measurable improvements in four indicators tied to UN Sustainable Development Goals (SDG) 13 (Climate Action) and 8 (Decent Work and Economic Growth) focusing on CO₂ emissions per capita, low-carbon energy generation per capita, employment in the renewable energy sector, and gross value added (GVA) in power and utilities sectors. Using annual data from 2014–2023 from the Reserve Bank of India, the Ministry of New and Renewable Energy, and the World Bank, this study applied Pearson and Spearman correlations and linear regressions to evaluate the economic model. Results show green bond issuance is strongly associated with economic growth and low-carbon energy generation, but carbon emissions per capita also rose, and employment effects were modest. These findings suggest green bonds alone cannot guarantee environmental progress. Some data limitations include a short time span, low frequency, and causality issues, underscoring the need for more research. Based on the findings, this study recommends actionable insights on stronger verification standards, clearer policy design, and incentive structures to help emerging markets harness green finance for a truly sustainable future.

Introduction

Today, climate change is accelerating at unprecedented rates. Global CO₂ emissions reached 37.8 billion tonnes in 2023, the highest on record¹. Rising emissions drive more frequent hurricanes, wildfires, droughts, and heatwaves, threatening ecosystems, food and water security, and human health. Outdoor air pollution alone causes an estimated 4.2 million premature deaths annually², and climate-related disasters result in billions of dollars in economic losses each year³.

This emphasizes the importance of transitioning towards green economies. To do this, however, requires investment in infrastructure and green energy projects around the world. Without such investment, the environmental, economic, and public health consequences of rising emissions will continue to worsen.

Emerging economies are facing a unique challenge compared to developed economies. Often, their expansion of clean energy is outpaced by their rapid population growth and unhealthy industrialization practices. They lack the resources and the incentives to grow sustainably. India is a prominent example of this. It is the third-largest CO₂ producer in the world. Emissions have risen from 1.6 tonnes per capita in 2015 to 2.0 tonnes per capita in 2023⁴. India’s total energy demand has grown by more than 30%, and renewable energy must grow tangentially to support the population.

In recent years, green bonds have been emerging as a potential solution. Green bonds are defined as debt securities whose proceeds are earmarked exclusively for projects that generate measurable environmental benefits, as per the International Capital Market Association (ICMA) and the Securities and Exchange Board of India (SEBI). Put simply, they direct investments towards low-carbon energy projects around the world. 

Despite the promise of green bonds, evidence from other emerging economies highlights some risks and unintended outcomes. China, for example, has demonstrated that rapid economic growth without strong oversight can result in a massive carbon footprint and environmentally unhealthy business practices. As such, in the 2024 Environmental Performance Index (EPI), China was ranked 156th out of 180 countries with a score of 35.4⁵. Yet, China is the number one issuer of green bonds in Asia⁶. This may be attributed to “greenwashing,” where projects are labeled “green” without actual, measurable environmental benefits. This further shows the importance of green bond verification and the wider adoption of stricter policies and practices recommended in this paper.

In India, green bond issuance has surged from about $1.1 billion in 2015 to $10 billion in 2023. Over 80% of this activity comes from the corporate and banking sectors, hence the focus of this study. Sovereign green bond issuance for Indian projects began recently in 2023, and while the data remain limited, their inclusion in future research could provide valuable insights as the market matures. India was also the first country to introduce a corporate social responsibility (CSR) mandate, requiring companies to allocate 2% of their profits to ESG-related initiatives.

Together, these developments signal India’s growing ambition to position itself as a global leader in low-carbon growth.

Still, the country faces a difficult balance: sustaining rapid economic expansion and a growing population while tackling pollution and climate challenges. Green bonds present a promising way to channel capital toward sustainable development, but their true potential depends on whether these investments produce measurable impact and are not overshadowed by fossil fuel expansion. Until then, this challenge will persist.

With the stage set for India, the purpose of this study is to answer the following research question: Is green bond issuance in India correlated to an improvement in UN Sustainable Development Goals 8 (Climate Action) and 13, specifically regarding CO₂ emissions per capita, low-carbon energy generation per capita, employment in the renewable energy sector, and gross value added (GVA) in power and utilities sectors? The objectives of this study are to (1) quantitatively assess the relationship between corporate green bond issuance and key environmental and economic indicators in India, (2) analyze the implications of green finance in supporting low-carbon energy development, and (3) provide actionable insights for policymakers, investors, and corporations to strengthen sustainable finance outcomes. 

Literature Review

Introduction to Green Bonds

Green bonds have rapidly expanded since their introduction in 2007. By 2023, the global market had surpassed USD 2.5 trillion, and it has grown to be a central financial instrument around the world^7,8. With different varieties of structures, including use-of-proceeds, revenue, project, and securitized bonds⁹, green bonds may fund projects across many sectors.

These sectors include renewable energy, carbon emission reduction, green transportation, sustainable housing, and clean water. Carbon emissions and renewable energy have been shown to be the most critical metrics to assess effectiveness¹⁰.

Not surprisingly, emerging markets have become key players in the green bond landscape, with India being a major attraction. In 2024, green, social, sustainable, and sustainability-linked (GSSS) bond issuance reached a record USD 1 trillion in emerging markets. Looking forward, annual investments in clean energy in emerging markets are expected to double in the coming years¹¹.

Positive Impacts of Green Bonds

Overall, green bonds may have good potential to bridge the gap between environmental necessity and financial opportunity. Flammer (2023) finds that the issuance of green bonds per capita is often associated with subsequent reductions in CO₂ emissions. This can be especially true if third-party verifiers are involved, meaning that climate and financial outcomes are closely linked with strong oversight.

Compared with conventional bonds, green bonds can also offer competitive financial returns. Because they diversify funding sources, it can appeal strongly to ESG-conscious investors. These investors have recently become a significant portion of the global financial community, meaning green bonds may enhance market credibility and open access to a broader investor base¹².

Shortcomings and Risks

Green bonds are not without shortcomings and risks. Sectoral concentration is a significant one, as a large share of green bond proceeds are currently flowing into the renewable energy sector which overshadows other important areas such as sustainable housing, clean water, or biodiversity conservation. This imbalance may create scenarios like the economic phenomenon known as “Dutch disease”. This is where heavy capital inflows into a single sector distort broader development priorities¹³.

Studies also highlight that simply issuing green bonds is insufficient in creating environmental benefits; the effectiveness of these instruments depends on governance structures, certification practices, and the rigor of valuation methods. Qian and Yu (2024) demonstrated that the performance of green investments is closely linked to the quality of corporate governance, emphasizing the importance of strong oversight. Argentiero et al. (2023) call for more robust and standardized valuation frameworks.

Additionally, greenwashing has become a significant issue in recent years. It happens when projects that are supposedly “green” do not actually deliver on their environmental benefits. Unfortunately, without strong third-party verification and transparent reporting, unsuspecting investors may fall for this trap. This will be a pressing concern as the market scales. Investor confidence and credibility of the project is highly important in maintaining trust¹⁴, and without this, projects may have a higher likelihood to fail or be cut from funding.

Several studies note that the impact of green finance or green bond investment on emissions, energy metrics, or employment often unfolds with a delay rather than instantaneously. For example, research on green finance in China finds evidence of inverted U-shaped relationships between green finance and carbon emissions, where the beneficial effects on emissions reduction become significant only after surpassing a certain development threshold, suggesting a lag in impact¹⁵.This implies that early investments might not immediately yield observable environmental benefits, and that lagged effects may vary across countries depending on policy design, regulatory maturity, and institutional capacity.

In sum, according to the literature, green bonds need to be implemented with careful market design, stronger governance, and broader diversification. This way, it will deliver equitable climate solutions, provide strong returns, and prevent the occurrence of the “Dutch disease”.

India’s Renewable Energy Goals

According to COP26 submissions, India aims to achieve 500 GW of non-fossil energy capacity by 2030. They want to meet 50% of its energy needs from renewable sources by 2030 and reduce total projected carbon emissions by one billion tonnes. Their goal is to reach net zero emissions by 2070¹⁶.

However, the country would need $1.6 trillion in investments to achieve full decarbonization by 2050. Scenario analyses also suggest that coal-based power must peak by 2040 and decline by 99% between 2040 and 2060, while solar electricity generation capacity must increase to 1,689 GW by 2050 and 5,630 GW by 2070 to meet energy demands sustainably¹⁷.

Integrating CSR with green bond initiatives may be beneficial. Capital can flow into renewable energy projects, help increase low-carbon energy capacity, reduce CO₂ emissions, and enhance the credibility of corporate sustainability initiatives. By showing tangible outcomes, investors’ confidence will also be boosted^10,12.

Green Bonds in India

India has become the world’s second largest green bond issuer in Asia, second only to China, issuing about USD 10 billion by 2023¹⁸. To guide the market, the Securities and Exchange Board of India (SEBI) established a framework in 2021 that lists eligible areas such as renewable energy, clean transportation, water and waste management, sustainable land use, and biodiversity conservation. But, despite the promising efforts, India’s green bond market faces several roadblocks that slow growth.

Today, there is low investor trust in the Indian market. This is due to high transaction costs, limited use of certified or “green-labeled” bonds, and the lack of reliable bond ratings¹⁹. For issuers such as banks, possible green washing concerns are scaring investors. This is especially due to problems such as weak creditworthiness and the lack of independent verification^20,21,22. Finally, Verma & Agarwal, (2020) and Verma & Bansal, (2023) show that an absence of tax incentives and unattractive sovereign rates, or in other words, limited government support, is holding India back.

All the above-mentioned overlapping barriers explain why the green bond market has not scaled up as quickly as expected, even with India’s size and ambition.

There is also significant room for improvement in existing literature. As Zhang et al. (2019) and Tao et al. (2022) argue, more country-specific research is needed to understand how tools like green bonds can truly support sustainable development.

Research Objectives and Theoretical Framework

Most research on India’s green bonds has been qualitative, focusing on case studies, policy analysis, and market barriers^20,12,21. So far, these studies argue that green bond issuance is effective in reducing CO₂ emissions, expanding renewable energy capacity, and supporting economic growth^23,24. There has also been extensive quantitative research on green bonds in other contexts like China and developed markets around the world²⁵. The biggest gap in the literature is the lack of quantitative research of India and other emerging markets. Emerging markets are important because they are less likely to achieve environmental objectives. They often face bigger challenges in governance, verification, and transparency^23,7. Thus, conclusions that are drawn from research on developed markets like the U.S or U.K may not be entirely applicable to India. 

This study aims to contribute to filling that gap by conducting a quantitative analysis of green bond issuance in India. Figure 1 demonstrates the theoretical framework used to examine green bonds’ effects on the respective indicators linked to UN Sustainable Development Goals (SDG) 8 and 13: CO₂ emissions per capita, low-carbon energy generation per capita, employment in the renewable energy sector, and gross value added (GVA) in power and utilities sectors. Green bond issuance is in the top, indicating it is the independent variable that will be measured against all four dependent variables.

By using issuance data and robust statistical methods, this study will answer the question of whether green bonds achieve their intended environmental and economic outcomes in the Indian context. Beyond measurement, this study will provide actionable insights for policymakers, investors, and corporations. In doing so, this study looks to add to the growing body of work on the real impacts of green bonds.  Hopefully, this work will be able to extend to other emerging economies around the world, not just India.

Figure 1 Theoretical Framework

Methodology

This study investigated the relationship between corporate green bond issuances in India (2014–2023) and key indicators of environmental and economic performance, specifically linked to Sustainable Development Goals (SDGs) 13 – Climate Action and 8 – Decent Work and Economic Growth.

Variable Measurement

Four dependent variables were selected based on their relevance to the study’s objectives and measurable linkage to SDGs:

• CO₂ emissions per capita (t/person, SDG 13): Average annual carbon dioxide emissions in tonnes per individual in India.
• Low-carbon energy generation per capita (kWh/person, SDG 13): Availability of low-carbon electricity per person.
• Employment in the renewable energy sector (millions, SDG 8): Workforce employed in renewable energy industries.
• Gross value added (GVA) of the power and utilities sector (₹ crore, SDG 8): Economic output of the sector.

The independent variable, green bond issuance, is measured in USD billions issued by Indian corporations per year. Units have been defined to ensure clarity and comparability across variables.

Data Table

This study uses yearly data from 2014 to 2023 for all variables, summarized in Table 1 with mean, standard deviation, minimum, and maximum values. This study compiled data from primary sources and internationally recognized organizations to ensure reliability. This study obtained the GVA for India’s power and utilities sector through the Ministry of Statistics and Programme Implementation (MOSPI) and adjusted to 2023 prices using the GDP deflator and with no further imputations. This study sourced CO₂ emissions per capita (metric tons) from the International Energy Agency (IEA), with no further imputations. This study obtained low-carbon electricity generation per capita (kWh) from Our World in Data with no further imputations. Employment in the renewable energy sector was collected from IEA, ILO, and IRENA reports with no further imputations. Finally, green bond issuance data (USD billions) was obtained from the Climate Bonds Initiative. For 2022–2023, green bond issuance was not directly reported, so these values were included by multiplying the total sustainable debt issued in India by the proportion classified as green bonds. Other than that, no further imputations were needed, and all datasets are standardized by unit and aligned by year.

Methods and Justification

This study assessed the correlation between green bond issuance and each economic and environmental indicator through Pearson and Spearman correlation coefficients. Spearman captures trends that are not strictly linear and is robust to outliers, while Pearson measures linear associations and the strength of those relationships. These methods were chosen over Kendall’s tau or partial correlations because they are sensitive to different trend types. Spearman and Pearson also work together well to provide complementary insights. They also work well with small sample sizes and variables in very different units, such as billions of USD for green bonds, per capita kWh, employment in millions, or GVA in ₹ crore.

After employing Spearman and Pearson, simple linear regressions were calculated to estimate the economic model and quantify the direct relationship between green bond issuance and each dependent variable. Green bond issuance served as the independent variable, and this study reported slope, R², and p-values. Given the limited dataset of only 10 annual observations per variable (2014–2023), linear regression is appropriate to explore these relationships because it estimates both the direction and magnitude of associations while remaining interpretable. Although linear regression cannot fully capture lagged or nonlinear dynamics, it provides a useful preliminary understanding of the relationships. Vector Autoregression (VAR) and Granger causality are standard methods for examining time-lagged effects, but with such a small sample, these tests become statistically unreliable. Simulations show that with limited time points, standard Granger causality tests can yield false-positive rates of up to 100%, meaning they may incorrectly detect causality where none exists²⁶. Therefore, while VAR and Granger causality are better suited for larger, higher-frequency datasets, linear regression offers a more stable and interpretable approach for this study.

Pearson Correlation

Here, x represents the annual value of green bonds issued by Indian corporations (in USD billions), while each yᵢ represents the observed value of a dependent variable for year i, corresponding to CO₂ emissions per capita, renewable electricity generation per capita, employment in the renewable energy sector, or gross value added of the power and utilities sector. The mean of each variable, ȳ, represents the average value across all years studied. In the Pearson correlation calculation, the difference yᵢ − ȳ captures how each year’s observation deviates from the overall average. The Pearson correlation coefficient, r, quantifies the strength and direction of the linear relationship between x and y, with values ranging from −1 (perfect negative correlation) to +1 (perfect positive correlation), and 0 indicating no linear correlation.

Spearman Rank Correlation

Here, ρ represents the Spearman rank correlation coefficient measuring the strength and direction of monotonic relationships between green bond issuance and each dependent variable as outlined earlier. For each year, i indexes the observation, n is the total number of years in the study, and dᵢ is the difference between the rank of green bond issuance and the rank of the dependent variable for year i. A ρ value of +1 indicates a perfect increasing monotonic relationship, −1 indicates a perfect decreasing monotonic relationship, and 0 indicates no monotonic association. The difference dᵢ allows the analysis to quantify how each year’s ranking deviates from a perfectly monotonic trend, providing insight into whether greater green bond issuance aligns with higher or lower environmental and economic performance indicators.

Results and Analysis

This section presents the findings on the relationship between corporate and bank green bond issuances in India (2014–2023) and environmental and economic indicators aligned with SDGs 13 and 8. The most statistically significant results are bolded.

Environmental Indicators (SDG 13)

What is unexpected is that per capita CO₂ emissions increased over the study period. The Pearson (r = 0.705, p = 0.023) and Spearman (ρ = 0.648, p = 0.043) correlations indicate a strong positive association. Regression analysis shows a slope of 0.03 t/USD billion with R² = 0.497 (p = 0.023).

In contrast, low-carbon electricity generation per capita shows a moderate positive relationship with green bond issuance (Pearson r = 0.591, p = 0.072; Spearman ρ = 0.697, p = 0.025). The regression slope is 8.72 kWh/USD billion and R² = 0.349 (p = 0.072).

In sum, green bond issuance has a moderate, positive correlation with low-carbon electricity generation and a strong, positive correlation to CO₂ emissions. 

Economic Indicators (SDG 8)

Employment in the renewable energy sector has increased steadily from 2014–2023. There is a positive but less significant correlation with green bond issuance (Pearson r = 0.554, p = 0.097; Spearman ρ = 0.552, p = 0.098). For regression analysis, there is a slope of 0.043 million jobs/USD billion and R² = 0.307 (p = 0.097). This suggests a modest, positive correlation between green bonds and job creation. 

In contrast, gross value added (GVA) of the power and utilities sector shows a strong and statistically significant association with green bond activity. Pearson r = 0.714, p = 0.020; Spearman ρ = 0.709, p = 0.022), with regression slope 12,017 ₹ crore/USD billion and R² = 0.510 (p = 0.020).

In sum, green bond issuance has a strong, positive correlation with GVA but a positive, less statistically significant correlation with renewable energy employment.

Implications

Below are some possible reasons why these trends may be appearing considering correlation does not imply causation.

There is a divergence between economic and environmental outcomes in India, based on this study’s analysis. On the one hand, green bonds in India may drive growth in the GVA of the power and utilities sector, as well as support the expansion of low-carbon energy access. This can be explained by the fact that green bonds ease financing constraints and allow utilities to invest more quickly in grid upgrades, solar and wind projects, and other infrastructure, bringing energy to more people. Furthermore, green bonds lower the cost of capital which may encourage utilities to invest in higher-risk or longer-term renewable projects that they might otherwise delay or avoid.

On the other hand, despite this infrastructure growth, the impact on per capita CO₂ emissions reduction remains limited. This aligns with prior research suggesting that the environmental effects of green finance often emerge over time, with measurable reductions appearing only after projects reach operational maturity¹⁵. One likely explanation is that India’s overall energy demand continues to rise rapidly, and fossil fuels still supply a significant portion of electricity. Even as renewable capacity grows, total energy consumption may increase faster than the displacement of fossil fuels, offsetting immediate reductions in emissions.

Next, employment in the renewable sector also seems to lag behind investment. This may be because new projects require construction, technical expertise, and workforce training, which take time to scale. Workers might not be equipped and educated with the proper skill sets to operate green energy facilities, therefore affecting employment. Such delays are consistent with findings that green bond impacts on employment often lag behind capital deployment, reflecting both project development timelines and the need for workforce readiness¹⁵.

The findings also highlighted the risk of greenwashing and the need to ensure green bond funds are directed toward truly impactful projects. In emerging markets like India, continued independent monitoring will be essential.

Limitations of the Findings

This study has several limitations that should be considered when interpreting the findings. First, it relies on annual data from 2014 to 2023, which only provide a limited 10-point dataset for each metric. Some gaps in green bond data, particularly for 2021 and 2022, were filled using linear interpolation, which could introduce measurement error. Second, the dataset does not explicitly account for broader macroeconomic or policy factors, making it difficult to isolate the impact of green bonds alone. Third, the study employs linear models, which may not fully capture potential non-linear relationships or more complex interactions between variables. Fourth, while the discussion often attributes limited impacts on CO₂ emissions and employment to time-lag effects, this study did not explicitly model these dynamics. Advanced approaches like Vector Autoregression (VAR) or Granger causality tests, which are better suited for capturing delayed effects, were not feasible given the annual data and limited sample size. Finally, the findings focus on India and may not be directly generalizable to other emerging markets, which can differ in market maturity, regulatory frameworks, and economic structures. Collectively, these limitations highlight the need to interpret results cautiously and point to the value of future research using more detailed data and advanced modeling to better capture the complex impacts of green finance.

Nonetheless, while recognizing its limitations, the combination of correlation analysis and linear regression in this study is still suitable for providing initial insights into the relationship between green bond issuance and environmental and economic indicators in India.

Discussion

The study’s objectives were met, but the findings show a nuanced picture. Green bonds have a positive correlation with and appear to support economic growth and low-carbon energy capacity. There is a positive, less statistically significant correlation with renewable energy employment. However, green bonds have a positive correlation with and limited immediate impact on per capita CO₂ emissions. This is likely due to India’s rapidly growing energy demand and continued reliance on fossil fuels. The reason why job growth in the renewable sector lags behind investment, may be due to the time needed for project development and workforce training. Overall, this highlights both the potential and challenges of using green bonds as a tool for sustainable development in India.

Focusing on India is important because most research has looked at developed countries with established financial institutions, regulations, and infrastructure. As an emerging economy, India has comparatively immature financial institutions, constantly evolving green finance markets, and faces unique regulatory challenges. This study provides one of the first quantitative assessments of green bond issuance in India and its relationship to indicators linked to Sustainable Development Goals (SDGs) 8 and 13. Thus, this study fills a critical research gap and offers lessons for other emerging economies seeking to leverage green finance for sustainable development.

Overall, these findings connect directly to the broader sustainable development agenda: green bonds can mobilize private capital toward low-carbon infrastructure, demonstrating the potential of financial innovation to support UN SDGs 8 and 13. Yet, realizing tangible environmental and social outcomes requires coordinated efforts across finance, policy, and human capital development. Green finance is a tool, not a standalone solution.

Policy Recommendations

To ensure that green bond investment translates to tangible environmental and economic outcomes in India and other emerging markets, this study recommends the following policies and practices based on the findings:

Verification and Anti-Greenwashing Reporting Standards

Require mandatory reporting and independent, third-party verification of project outcomes, including metrics such as CO₂ emissions reductions, low-carbon energy capacity installed, and jobs created. Establishing a public registry of verified green projects will improve transparency and maintain investor confidence, reducing the risk of greenwashing. Furthermore, green bonds should be certified and reported according to recognized international standards by trusted organizations like the Climate Bonds Initiative. Issuers should face penalties for misreporting or failing to meet stated environmental targets.

Incentive Structures

Policymakers should implement targeted incentives, such as tax breaks or concessional financing, for projects that demonstrate verified environmental and social results. Milestone-based financing can ensure that bond proceeds are disbursed only after projects meet verified outcomes. Introducing blended finance models combining public (government) money and private (investor) money together can make projects less risky and encourage more investors to put money into green energy projects.

Employment and Workforce Development

Businesses should invest in workforce development programs, including technical training, certification initiatives, and collaboration with universities and industry associations, to ensure that sufficient skilled labor is available for green energy projects. Encouraging project developers to include explicit hiring and workforce plans in green bond proposals will accelerate employment growth and address the time-lag effects between green bond issuance and renewable energy employment.

Long-term Monitoring and Adaptive Policy Design

Financial growth and infrastructure development often precede environmental and employment outcomes, so multi-year monitoring frameworks are important. Continuous monthly tracking of CO₂ emissions, renewable capacity, and job creation allows policymakers to adjust regulatory frameworks, improve incentives, and identify high-impact projects over time. Furthermore, this monthly data would be highly useful in future studies utilizing robust models like VAR or Granger causality tests to examine time-lag effects highlighted in the literature.

Future Research Directions

There are several ways future research could build on this study. First, using higher-frequency data, like monthly or quarterly observations, would give more data points and make it possible to apply models like VAR or Granger causality. These approaches would allow future studies to quantify the time-lagged effects highlighted in the literature and observed in India’s context.

Second, adding more detailed project-level data, such as third-party verification reports, environmental impact assessments, and detailed financial disclosures, would make the analysis more accurate. It would help address greenwashing risks and provide more exact data, such as date of green bond issuance, to help evaluate time-lag effects.

Third, including broader macroeconomic, policy, and sector-specific factors could be incorporated as a factor in the model to get a better picture. For example, government energy policies, fossil fuel reliance, and overall economic growth likely influence both emissions and employment outcomes. Accounting for these variables would make it easier to separate the pure impact of green finance from other forces at play.

Fourth, looking at multiple emerging markets in a comparative panel study could reveal how different contexts, like regulatory maturity, investor awareness, or energy demand, affect the success of green bonds. This would help us see which lessons from India apply more broadly and which are unique to its situation.

Finally, exploring non-linear models, threshold effects, and how policy incentives directly interact with investment could uncover more subtle mechanisms behind green bond impacts. This kind of analysis could provide more practical insights for policymakers, investors, and project developers, showing how to design effective, complementary policies to amplify the positive effects of green bonds.

Conclusion

In conclusion, green bonds in India are crucial in supporting the country environmental and economic growth. It has shown to have increased low-carbon energy access and delivered economy growth. However, CO₂ emissions reduction remains limited. Employment in the renewable sector also seems to lag behind investment. 

The path forward for green bonds is both challenging and full of potential. With more precise data, stronger verification, and robust policies, their true impact can finally be measured and maximized. For countries like India, this is more than an economic experiment; it’s a test of whether finance can truly fuel a more sustainable future.
