Exploring the Relationship Between Green Bond Issuance and Energy-related SDGs in Emerging Market and Developing Economies

Purpose The study analyses the impact of green bonds on sustainable energy efficiency in different Asia–Pacific economies. The research evaluates the support provided by green finance towards energy efficiency and low-carbon transformations in upper-middle- and high-income countries of Asia–Pacific. Design/methodology/approach The analysis within this study uses empirical data to understand resource efficiency changes caused by green bonds across the Asia–Pacific region. Panels of data from ten upper-middle- and high-income economies were analysed using an analysis method from 2011 to 2021. The evaluation utilizes different sustainability indices to measure how alterations in independent factors affect resource efficiency levels. The research employs CS-ARDL and analyses short-run and long-run relationships between resource efficiency and green bond issuance through panel data spanning from 2011 to 2021 across ten Asia–Pacific economies. The proposed model assesses intersectional dependencies by investigating five important variables, which include energy intensity, renewable energy consumption and carbon intensity of GDP and government effectiveness and GDP per capita growth. Findings The empirical result of the study shows that green bond issuance develops resource efficiency effectively at long-term timescales. Statistics show that raising green bond issuance by 1% leads to 0.20% better performance on the resource efficiency index (REI). Studies show that renewable energy use along with governance quality characteristics has beneficial results, whereas energy and carbon intensity produce harmful effects. Research limitations/implications Standardized data concerning green bond performance and energy efficiency metrics limit this research. Research should expand to study lasting effects and examine the impact of government policy on boosting the performance of green finance. Practical implications The research gives essential information about green bond structure optimization for policymakers and financial institutions to enhance their economic value and environmental impact. The situation reveals why financial institutions need transparent reporting practices, common impact measurement frameworks and regulatory stimulation to gain business trust in green investments. The study demonstrates how green bonds help organizations implement sustainable strategies by letting them follow worldwide ESG (environmental, social and governance) criteria. The financial access for energy efficiency projects with the help of green bonds manages to fill sustainability infrastructure funding gaps and promotes economic adaptation and resilience. Originality/value The study introduces a novel empirical approach to analysing the impact of green bond issuance on resource efficiency across the Asia–Pacific region, using the CS-ARDL model. Its regional scope, combined with robust statistical techniques and a custom resource efficiency index, brings fresh insights into green finance. It extends the body of knowledge by integrating energy and environmental economics with sustainable finance. The study’s long-run analysis of green bonds’ effectiveness is particularly innovative and relevant.

The transition toward renewable energy in emerging economies requires innovative financing instruments that can bridge investment gaps while ensuring sustainability. Among such instruments, green bonds have gained prominence as a critical mechanism to mobilize private and institutional capital for climate-related projects. However, the expansion of green bond markets in emerging regions such as Africa and Asia has faced structural and institutional constraints. This review article investigates the role of policy innovation in accelerating green bond markets for renewable energy, focusing on evidence from emerging economies. By systematically integrating insights from more than 80 academic and policy sources, the paper provides a comprehensive framework that links policy innovation, institutional capacity, market maturity, and renewable energy financing to the expansion of green bond issuance. The study adopts a multi-method empirical synthesis, including descriptive statistics, correlation analysis, fixed effects regression, feasible generalized least squares (FGLS), and dynamic panel two-step system generalized method of moments (GMM). These approaches are complemented with robustness checks, sensitivity analyses, and sub-sample evaluations covering the 2007–2008 global financial crisis and the COVID-19 pandemic (2020–2021). The results demonstrate that policy innovation exerts a strong positive effect on green bond issuance, both directly and indirectly, by strengthening institutional capacity, enhancing sovereign green bond credibility, and improving renewable energy financing channels. Furthermore, the analysis confirms that policy-driven instruments moderate the adverse effects of crises, thereby safeguarding renewable energy investment flows even during systemic shocks. Key findings reveal that (i) policy innovation significantly improves the attractiveness and credibility of green bond markets; (ii) institutional capacity and governance quality serve as mediating and moderating channels; (iii) green bond issuance contributes to renewable energy expansion and long-term market maturity; and (iv) external shocks such as financial crises and pandemics reshape but do not eliminate the positive role of innovative policies. The study also highlights important regional contrasts, with Asia displaying faster institutional adaptation and Africa requiring greater regulatory harmonization to unlock potential. This review contributes to both theory and practice by advancing a theoretical framework that integrates policy innovation with green finance and by offering empirical evidence that underscores the importance of regulatory adaptability in achieving sustainable development goals (SDGs). Policy implications emphasize the need for governments to design flexible, transparent, and credible green bond policies, while investors are encouraged to align portfolios with climate-resilient assets. The paper concludes that green bonds, underpinned by robust policy innovation, can serve as catalytic tools for financing renewable energy transitions in emerging economies.

Green bond vs conventional bond: Outline the rationale behind issuance choices in China

Implementing the concept of social responsibility at various levels has led to the growth of ESG investing, focusing on environmental, social and governance factors. Impact investing goes beyond ESG, focusing on the assessment of contributions to meeting the needs of society and protecting the environment. The UN's Sustainable Development Goals (SDGs) provide a framework for global action, bringing together the financial and organizational efforts of stakeholders. The economic aspects of implementing projects in sustainable development and social responsibility are represented by a wide list of financial instruments designed to ensure the accumulation of funds and their direction in relevant development directions. Green, Social, Sustainable and Sustainability-Linked Bonds (SLB) formed the so-called GSSS pool, which formed the basis for responsible investing. Global ESG assets are expected to exceed $40 trillion by 2030. USD. The European Union, thanks to strong institutional support, led the upward trend of active use of GSSS bonds and became the leader of developed markets. Green, social, sustainable and sustainable development bonds play an important role in financing the SDGs. The structure of GSSS is dominated by green bonds, which are associated with a high risk of climate change. Despite the difficulties, supranational institutions are driving responsible investment trends, focusing on the environmental component. Emerging markets, particularly in the Asia-Pacific region, are showing resilience in green bond issuance, with growth projected through 2027. A comparative analysis of placement and direction of loan funds was conducted in a geographical section, between issuers and developed, emerging and supranational markets. The use of proceeds from GSS bonds demonstrates the issuers' strategic interests: renewable energy, construction, and transport. A forecast of the emission of green bonds for the period up to 2027 in various market segments has been developed. Despite the different names and investment directions of GSSS bonds, they are a valuable tool both for achieving the goals of sustainable development and for the implementation of corporate social responsibility projects.

Green bonds allocate proceeds towards environmentally beneficial projects and sustainable development goals, distinguishing themselves from traditional bonds primarily in the use of proceeds determination. However, investors often find it challenging to assess the carbon reduction potential of these bonds because of the lack of standardised environmental impact reporting. In response to this, our research constructs a unique set of indicators derived from financial and environmental datasets, using multivariate analysis techniques that can accommodate the detection of both linear and non-linear relationships. A novel method combining kernel Principal Component Analysis (kPCA) and Canonical Correlation Analysis (CCA) is applied to detect spatial–temporal cross-correlation in multivariate datasets. This approach handles variable comparability issues and the differential treatment of categorical and numerical variables. A significant finding of this study emerges when this methodology is applied to financial attributes obtained from green bonds issued by municipal agencies (muni bonds), pollution data and environmental (climate) data from nine California counties.The results of the detailed analysis indicate that there is measurable evidence to indicate relationships between green bond issuance and their use of proceeds for pollution reduction efforts. In particular, the results show a clear and interpretable correlation directly linked to the amount of green bond issuance and the effect this is having on pollution reduction, underscoring the tangible impact these financial instruments have on pollution reduction efforts in California.Conversely, when it comes to detecting spatial–temporal relationships between the use of proceeds from green bond issuance and positive climate change effects, this is inconclusive from the current studies’ analysis. It was found that there were weaker cross-correlation relationships observed between climate and green bond financial data set attributes which is perhaps indicative of the fact that climate change effects take a much longer time frame to occur. As such the findings of the analysis in this regard may not indicate that positive climate change effects are not occurring from green bond initiatives, but rather that the ability to measure detectable improvements to climate with regard to the issuance of green bonds is currently limited and will take longer for such effects to manifest in a statistically detectable fashion from the given data. This is particularly likely to be the case given green bonds are only in their infancy as a financial market, having had the earliest issuance only occurring in the last 15-20 years and only substantial growth in the market over the last 10 years. Therefore, this aspect of the research investigating longer-term climate effects with regard to green bond issuance will take longer to develop.

This article explores two primary questions: first, whether the issuance of green bonds contributes to environmental protection, particularly regarding their performance after the adoption of net-zero emission policies; and second, whether issuers of green bonds can have economic benefits. Using the Difference-in-Differences (DID) model to analyze green and conventional bonds issued from 2013 to 2023, the study finds no significant correlation between green bond issuance and CO2 emissions following net-zero adoption. Nevertheless, our findings are important and deserve attention as they indicate that the carbon reduction policies have not exerted sufficient pressure on bond issuers to reduce emissions. At the same time, however, a closer examination of issuing entities reveals that those issuing only green bonds tend to have higher ESG ratings, lower CO2 emissions, and lower financing costs. This suggests that such issuers achieve substantial environmental benefits and economic advantages. In contrast, entities issuing both conventional and green bonds do not demonstrate the same environmental benefits. This finding raises concerns about potential greenwashing, suggesting that entities issuing both green and conventional bonds may engage in practices that contradict environmental protection while presenting their activities as environmentally friendly through green bonds. The study also highlights that the impact of bond features on ESG scores and CO2 emissions varies significantly across different types of issuers. Finally, the paper recommends that policymakers strengthen carbon reduction policies, establish mechanisms to prevent greenwashing, and integrate CO2 emissions and ESG factors into assessment systems. Additionally, it calls for special attention to the carbon emissions of entities in low- and middle-income countries, as well as those in the manufacturing sector, to support the healthy development of green finance.

China has become one of the major green bond issue countries and is the only developing country. Research on green corporate bonds is currently a novel direction, and very few studies focus on the Chinese market. Researching Chinese corporate green bonds is essential for the Chinese and merging market. This article discusses corporate green bonds in the Chinese market from the perspective of stock market reaction, institutional investor positions and cost of capital. Firstly, the author analyzes the Chinese stock market reaction to the issuance of corporate green bonds by using an event-study methodology. The paper finds that Chinese stock markets respond positively to green bond issuance announcements, but this response reflects speculative trading behavior. Secondly, the author compares the stock positions of institutional investors after the issuance of corporate green bonds and finds that green corporate bond issuance in the Chinese market can attract long-term investors (institutional investors). Finally, this author adopts the exact matching method to verify the cost of capital argument and finds no significant benefit to the cost of capital, which is consistent with prior works.

The growing urgency of achieving sustainable development goals, particularly reducing carbon emissions, has highlighted the need for an effective financial instrument to channel capital towards green projects. Although green bonds represent a promising new tool forfinancing environmentally friendly initiatives, research on their direct environmental impact is still ongoing. This study examines the relationship between green bond issuance and carbon emissions, utilizing data from 72 countries between 2014 and 2020. Employing the generalized methods of moments model and rigorous robustness tests, the study finds a statistically significant negative association between green bonds and carbon emissions per capita. However, the impact varies across countries based on their income levels and existing renewable energy deployment. Notably, the effects of green bonds on carbon dioxide emissions per capita weakenin nations with higher income and renewable energy use, suggesting potential diminishing returns from green investment. These findings imply that policymakers should prioritise the development of green bond markets while tailoring policies to optimise environmental benefits, considering variations in clean energy infrastructure. Beyond the empirical contribution, this study advancesthe theoretical discourse in green finance by highlighting green bonds as a distinct mechanism through which financial markets can influence environmental outcomes. By quantifying the environmental impact of green bonds and providing nuanced policy recommendations, this study contributes to a more informed approach to financing sustainable development.

This study employs a multi-period difference-in-differences (DID) model to examine the impact of green bonds on corporate green innovation, as well as the heterogeneity and underlying mechanisms, using data from non-financial A-share listed companies in China from 2013 to 2023. The results indicate that issuing green bonds significantly promotes corporate green innovation, a conclusion that is corroborated by robustness tests. Heterogeneity analysis reveals that, compared to green medium-term notes, green corporate bonds and green enterprise bonds have a more pronounced effect on corporate green innovation. In terms of innovation types, green bonds exert a stronger influence on green invention patents than on green utility patents. From an industry perspective, non-polluting industry firms exhibit a more substantial increase in green technological innovation levels after issuing green bonds. Regarding media attention, the positive effect is more evident in firms with higher media coverage. In terms of firm ownership, state-owned enterprises demonstrate a more significant improvement. The mechanism analysis shows that green bond issuance enhances corporate green innovation by increasing R&D investment, alleviating financing constraints and reducing agency costs. Additionally, spillover effect analysis indicates that green bond issuance by one firm leads to an increase in green innovation levels among other firms in the same industry or city, suggesting a significant positive externality. This study provides a new perspective for understanding the impact of green financial instruments on corporate sustainable development.

PurposeThe present study examines the rationale behind the increased global presence of corporate green bonds as a green financing tool to facilitate sustainable practices and eco-friendly investing. The authors investigate the intriguing question of whether the companies that issue green bonds are valued more by investors or not, and further extend our analysis by exploring whether the green image of companies helps to minimize the value erosion during a crisis and enhance the resilience of the stocks?Design/methodology/approachTo examine the association between environmental commitments and firm value, the authors use the COVID-19 crisis as an exogenous shock and create a perfect natural setting to eliminate the endogeneity bias from our estimations. Moreover, the authors use propensity score matching to choose a one-to-one match of green bond firms with a larger pool of brown bond firms and eliminate the “size effect” arising out of the disproportionate sample size of green and brown bond firms.FindingsThe results of the study indicate that green bond firms are valued more by investors compared to brown bonds firms. Hence, green bond issuance acts as a strong signal of a firm's environmental commitment and it is well recognized by the investors. One of the possible reasons for a higher value of green bond firms may be due to their ability to arrest value erosion during environmental shocks. The authors could not find any difference in the resilience of green and brown bond firms.Originality/valueThe study contributes to the growing literature in the area of impact investing, specifically on exponentially growing innovative instrument green bond. Our study integrates two areas of research, i.e. corporate finance and impact investing by examining the impact of green bond issuance on firm value and stock market returns. The results would help environmentally sensitive investors to devise their investment portfolios more efficiently.

Green bonds play a pivotal role in promoting sustainability by channeling financial resources towards environmentally friendly projects, fostering a greener and more resilient future. This research investigates the role of “Green Bonds” in the attainment of Sustainable Development Goals (SDGs), focusing on two specific goals: climate action, represented by per capita carbon emissions (CO2), and clean energy, represented by per capita renewable energy production. Using data from 2007, when the first green bond was issued, up to 2021, we employed a one-step generalized method of moments (GMM) model to explore how green bonds impact global emission reduction and the increase in renewable energy production. The findings demonstrate that green bonds have a significant influence on both emissions and renewable energy production. Specifically, green bonds and renewable energy production have a positive and significant association, while emissions exhibit a negative relationship with green bonds. Our results reported a reduction in carbon emissions up to 0.8 tons, while an increase in renewable energy up to 66 kWh. Upon analyzing the data before and after 2015, we observe that prior to 2015, there was no significant effect of green bonds on emissions and renewable energy production. However, after 2015, green bonds substantially impacted both indicators. Furthermore, our results indicate that countries with higher green bond issuance are more likely to achieve their sustainability goals, particularly in terms of renewable energy production and carbon emission reductions. Conversely, countries with lower green bond issuance are struggling to attain their sustainability objectives in these areas.

Going Green: Effect of green bond issuance on corporate debt financing costs

Despite the substantial increase in green bond issuance over the past decade, evidence on the drivers and costs of corporate green bond issuance is lacking. We develop four novel hypotheses on the determinants of firms’ choice between green and conventional bonds, by connecting the four distinct features of green bonds with relevant theories. We test these hypotheses on a sample of green and conventional bonds issued by US, Western European and Chinese firms between 2014 and 2021, using linear probability models and alternative approaches. Consistent with our hypotheses, we find that firms with higher reputational gains from being seen as green and a stronger focus on eco‐innovation are more likely to issue green instead of conventional bonds. Conversely, we obtain only limited evidence that green bond issuance is driven by the net benefits of additional disclosure and no evidence that green bond issuers cater to time‐varying investor preferences for corporate greenness. Our results, which survive several robustness tests, are relevant for corporate managers, investors and bond market regulators.

This paper analyzes the global and European green bond markets from different perspectives. The paper uses data on green bond issues on the global and European green bond market, in the period from 2013 to 2023. Research results show that the issuance of green and other sustainability-related revenue use bonds has increased in recent years. Europe remains the largest issuance region, accounting for more than half of global issuance. Green bond issuance globally and in Europe has experienced a tumultuous couple of years after reaching record highs of USD 575 billion and USD 326 billion in 2021, respectively. In 2023, Europe's green bond issuance recovered 11% year on year to USD 341 billion. It slightly outperformed the global markets, which recorded 10% growth to reach USD 581 billion. In line with 2022, the corporate sector fueled 2023 green volume, contributing 57% of issuance. Corporate issuers in Europe are mostly dominated by the energy, utilities, automotive, transport, and building sectors, all of which have hystorically been dependent on fossil fuels. Analysis of the capital markets in Bosnia and Herzegovina (BiH) indicates that the green bond market exists, and it started in 2023 when the first issue of green bonds was announced by a commercial bank on the local capital market (Banja Luka Stock Exchange). The key barriers to the development of the green bond market are the lack of appropriate institutional arrangements for green bond management, the issue of minimum size, and the high transaction costs associated with issuing green bonds.

Green bonds have emerged as a critical financial instrument to fund environmentally sustainable projects, aligning with global efforts to combat climate change and promote green infrastructure. This study examines the macroeconomic factors influencing green bond issuance in India, focusing on key determinants such as GDP growth, inflation, interest rates, ESG scores, and bond ratings. By analysing sectoral trends in green finance, the study identifies clean transportation as the leading recipient of green bond investments, followed by renewable energy and waste & water management. The research employs a quantitative approach, utilizing regression and correlation analysis to assess the impact of macroeconomic variables on green bond issuance. The findings suggest that GDP growth has a positive influence, while inflation acts as a deterrent. ESG scores and credit ratings significantly affect investor confidence, with well-governed firms attracting higher investments. Despite regulatory advancements by SEBI and adherence to Green Bond Principles (GBP), challenges such as greenwashing risks, policy inconsistencies, and market volatility persist. The study concludes that green bonds hold immense potential to support India's transition toward a low carbon economy, macroeconomic stability is ensured. Encouraging standardization in ESG assessments, enhancing transparency, and incentivizing underfunded sectors like waste management can further accelerate the growth of green finance. The research contributes to the existing literature by providing country-specific insights into India’s green bond market and offering findings to enhance its effectiveness in sustainable financing.
