Green bonds are relatively new in the financial market compared to other financial securities but are useful in financing environmentally friendly projects. Just like other financial securities, green bonds are affected by various factors, such as economic policy uncertainty. Our aim of this paper was to conduct a systematic literature review of the impact of economic policy uncertainty on green bonds. We sought to do a thorough analysis of the existing literature on the assessment of the impact of economic policy uncertainty on green bonds and the techniques used in assessing the impact. Our findings showed that economic policy uncertainty had a strong impact on the green bond, with its intensity varying by location. This impact tended to be more pronounced in periods of heightened uncertainty. Also, our findings highlighted that the assessment of the impact of economic policy uncertainty on green bonds gained popularity in 2019, with China emerging as a prominent contributor. However, other countries, such as Finland, even though they had few published papers, their citations signified the production of quality papers in this field. Additionally, we found that the application of the quantile analysis method was utilized by many recent studies, which signified its importance in this field. Our findings highlighted the importance of considering appropriate techniques in assessing the impact of economic policy uncertainty on green bonds while taking into account the paper quality.

Green bonds, a new green financial instrument, encourage enterprises to achieve high-quality development through green technology innovation. However, a lack of research is currently being conducted into the effect of green bond issuance in China. Can green bonds effectively empower enterprises to green innovation? What is the underlying mechanism? In the context of carbon-neutral strategies, it is significant to answer these questions scientifically. This paper uses a quasi-natural experiment of the launch of the green bond market in China in 2016 to conduct empirical studies based on the panel data of 1 558 non-financial Chinese-listed enterprises from 2015 to 2020 with the multi-period difference-in-difference model. The results show that ① issuing green bonds can significantly empower enterprises' green technology innovation. The empowering effect is mainly for green utility patents rather than green invention patents. This result remains after dynamic heterogeneity analysis, placebo test, and other tests. In addition, the effect has a lag. ② Heterogeneity tests show that this empowerment effect varies across enterprises with different property rights, industries, and regions. ③ In terms of the mechanism of action, green bonds can enhance enterprises' ability to innovate green technology by increasing the proportion of long-term loans and improving their debt structure. This paper broadens the relevant literature on the economic consequences of green bonds and the influencing factors of enterprises' green technology innovation and provides policy suggestions for further improving the analysis of green bonds.

As a novel financial instrument, green bonds require further research to understand their causal effects and theoretical mechanisms on sustainable development fully. This paper constructs a theoretical model that characterizes the issuance of green bonds as the extent to which social planners prioritize environmental benefits in bond markets. In this model, we define sustainable development as the geometric mean of environmental factor inputs and final production output. By maximizing consumer utility, this model elucidates the direct and non-linear relationship between green bonds and sustainable development. The paper empirically investigates this proposition using data from 19 European countries between 2018 and 2022. The results indicate that: (1) Green bonds significantly promote sustainable development. This financial instrument, designed to raise funds for environmental projects, can indeed promote sustainable development through clean and green resource allocation. (2) The promotional effect of green bonds on sustainable development increases significantly with improvements in innovation efficiency, industrialization rates, and savings rates. This finding elaborates on the conditions under which the positive impact of green bonds on sustainable development is enhanced. (3) Green bonds only promote sustainable development when a country's factor endowment structure reaches a specific threshold. Beyond this threshold, as the factor endowment structure becomes very high, the country's sustainable development gains sufficient momentum, diminishing the role of green bonds. This finding suggests that the positive impact of green bonds on sustainable development is contingent upon certain properties reflecting the economic basis. [ABSTRACT FROM AUTHOR]

Green bonds serve as an imperative financial tool for mitigating climate change risk and environmental sustainability. It has received significant attention in the current literature, with increased worldwide efforts to fight against global climate change. Yet, the direction of green bonds' literature is currently unclear. Therefore, this paper aims to deliver a comprehensive vision of the literary landscape of green bond research, in consideration of policymakers, major market players, and investors. To achieve this, bibliometric analysis is performed on 342 filtered articles found in the Scopus database, through VOSviewer and Biblioshiny package. A detailed and descriptive evaluation of scholarly data demonstrates the significance of green bonds in accomplishing the objective of sustainable finance and mitigation of climate change. This study broadens our understanding of the literature and conceptual growth of scholarly discussion of green bonds, which gives insight into developing a strong conceptual foundation and future directions for research.

Purpose: This paper aims to explore the quantile-specific short- and long-term effects of economic policy uncertainty (EPU) on the efficiency of the green bond market. Design/methodology/approach: This study examines the long-term cointegration relationship and the short-term fluctuation relationship of EPU, WTI crude oil price (WTI) and European Union Allowances price (EUA) with the green bond market efficiency (GBE) using the quantile autoregressive distributed lag method. Additionally, the authors analyze the differences before and after the Covid-19 pandemic. Findings: EPU has a significant positive impact on the GBE before the outbreak. However, during the crisis period, the impact of EPU and WTI was greatly weakened, whereas the impact of EUA was strengthened. Practical implications: This paper demonstrates the dynamics of GBE and its influencing factors under different periods. The findings provide insights for market participants and policymakers to gain a clearer understanding of the green bond market. Originality/value: This paper extends the study of green bonds by quantifying the GBE and elucidating the nonlinear relationship between efficiency and independent variables at different quantiles over different periods.

This paper studies the issuing pricing character of green bonds with the evidence from China and further analyzes the reason why green factor affects bond issuing pricing by analyzing credit rating's intermediary effect and exploring the mediating of policy incentives and third-party green certification. Furthermore, heterogeneity analysis is conducted to analyze how green factor impacts on bond issuing pricing at different quantiles and for companies in different industries or with different ownership. The findings include: (1) Green factor generally reduces the issuance interest rate of green bonds, though this effect is not significant at the low quantiles or at the early development stage. (2) Green factor's impact on bond issuing pricing occurs partly by improving bond credit rating, fully by this way for companies in the construction industry, but directly for companies in other industries. (3) For non-state-owned companies, green factor has direct effect on bond issuing pricing, but this effect is not significant for state-owned companies. (4) Third-party green certification and incentive policies enhance the reducing effect of green factor on the issuance interest rate. This study provides a theoretical reference for environment-friendly investors, financiers with green projects and the regulators caring about green finance. [ABSTRACT FROM AUTHOR]

Reducing carbon emission intensity is crucial for achieving sustainable development. Carbon emission intensity is expressively affected by the issuance of green bonds. Thus, it is imperative to assess the influence of green bond issuance on carbon emissions and examine their correlation. Such research holds great potential to expedite the overhaul and modernization of businesses and to construct a circular economy system. This paper uses the spatial Durbin model to draw empirical conclusions by using data from 26 provinces in China between 2016 and 2021. Firstly, under different spatial matrices, it has been analyzed that an increase of 1% in the issuance of green bonds leads to a reduction of 0.306% or 0.331% in carbon emission intensity. It shows that green bonds have the potential to substantially reduce carbon intensity. Additionally, the intensity of emissions in the current period is driven by the intensity of emissions in the previous period. Secondly, the analysis of mediated transmission suggests that green bonds can ultimately reduce carbon emission intensity by changing the energy consumption structure or improving the efficiency of green technology innovation. Thirdly, the analysis of heterogeneity shows that the inhibitory effect of green bond issuance on carbon emissions is stronger in less economically developed regions than in economically developed regions. There is a significant inhibitory effect of green bond issuance in neighboring provinces on local carbon emission intensity. This effect is present only in provinces in less economically developed regions and not in economically developed regions. [ABSTRACT FROM AUTHOR]

This paper examines the dynamic linkages among economic policy uncertainty (EPU), the green bond market, the carbon market, and the macroeconomy using the time-varying parameter vector autoregressive (TVP-VAR) model with monthly data spanning from January 2016 to December 2021. Additionally, it assesses the robustness and accuracy of the empirical results through the Bayesian vector autoregressive (BVAR) model. The findings indicate that EPU negatively affects the green bond market in the short term but has a positive impact in the medium and long term. Conversely, EPU has a positive impact on the carbon market in the short term but a negative impact in the medium and long term. Furthermore, the green bond market negatively influences the carbon market in both the short and medium to long term. These results suggest that emerging markets, such as the green bond and carbon markets, are influenced by EPU. The adverse impact of the green bond market on the carbon market, however, contributes to expediting China's attainment of its low-carbon objectives. Appropriate economic policies can play a vital role in accelerating the transition to a low-carbon economy. The study also reveals that the US-China trade war has expedited the development of green capital markets in China, despite its impact on the green economic transition in the country. These findings provide insights for the government and investors to formulate suitable strategies for risk mitigation. [ABSTRACT FROM AUTHOR]

This paper utilizes a climate justice perspective to examine municipal green bonds (MGBs), a green-labelled debt instrument issued by subnational governmental entities, such as municipalities or cities, that determines financial, social and environmental redistributions in the context of climate change. This analysis focuses on the origins and financial construction of MGBs as the "descendant" of US municipal bonds and provides data on their recent diffusion in Africa and Latin America. It then draws connections with the lessons learned from critical analyses of US municipal bonds. The case study section explores one wastewater MGB of San Francisco (California) and creates material and theoretical connections with MGBs issued to finance water infrastructure in Mexico City (Mexico) and Cape Town (South Africa). The article concludes that the analysis and implementation of municipal green bonds needs a climate justice approach in order to recognize and address the production and reproduction of climate injustices.

As the green bond market expands, an increasing number of Green Bond External Reviewers (hereafter 'GBER' or 'GBERs') have gained momentum among investors and financial regulators. A GBER enhances the credibility of green bonds and prevents greenwashing risk in the green bond market by reducing the information asymmetry between issuers and investors. China is the second largest issuer of green bonds in the world. The current Chinese GBER legal framework is insufficient to ensure green bond market sustainability. Our purpose in this paper is to analyze the inadequacies of the Chinese GBER regulatory framework and to provide suggestions for overcoming the potential challenges within it. A textual analysis of primary legal sources and secondary academic sources serves as the main research methodology in this study. This paper provides an in-depth analysis of China's GBER regulatory framework and addresses its shortcomings and weaknesses. Furthermore, given the evolving stage of the Chinese green bond market, this paper analyzes potential challenges for GBERs and proposes some suggestions to ensure high-quality reviews by GBERs.

Purpose: This paper aims to investigate the relationship between sustainable investments and a series of uncertainties from January 2014 to December 2021, including many economic and political turbulences and the COVID-19 pandemic. Design/methodology/approach: The authors use Rényi's transfer entropy method, a nonparametric flexible tool that considers both the center distribution and lower quantiles, capturing extreme rare events that give additional insights to analysis. Findings: The authors' results indicate significant bidirectional information transmissions between the crude oil volatility and sustainability indices. The authors report information flows between the cryptocurrency uncertainty and sustainability indices considering tail events. The results are essential for market participants making decisions during turbulent times. Originality/value: This paper is carried out for a variety of uncertainty measures and environmental, social and governance (ESG) portfolios of both developed and developing markets. It adds to literature in terms of methodology used. Rényi's transfer entropy methodology is first used to measure the relationship between uncertainties and ESG investments. [ABSTRACT FROM AUTHOR]

The imperative to achieve sustainable development in the face of accelerating urbanization has prompted an urgent re-evaluation of the role that municipalities play in driving environmentally conscious growth. This research paper delves into the critical nexus between municipalities and sustainable development in India, with a specific focus on the innovative financial instrument of green bonds. The study employs a comprehensive review of utility of Green Bonds in India and Internationally. Through this methodology, the paper seeks to shed light on the efficacy of green bonds in augmenting municipal initiatives towards sustainable urbanization. The findings of this research provide nuanced insights into the multifaceted roles that municipalities undertake in advancing sustainable development agendas. By analyzing the implementation of green bonds by municipalities in India and International countries, the paper discerns trends in the utilization of green finance for eco-centric urban projects. Moreover, it scrutinizes the influence of green bond proceeds on key sustainability indicators, such as reduction of greenhouse gas emissions, improved waste management, and enhanced green infrastructure. It also examines potential policy recommendations to overcome these impediments, thereby providing a roadmap for municipalities to more effectively leverage green bonds as a financial tool for sustainable urban development. In conclusion, this research contributes a comprehensive understanding of the pivotal role that municipalities play in advancing sustainable development and underscores the potential of green bonds as a transformative financial instrument in this endeavor. By providing review based in-depth research and practical insights, this paper offers valuable guidance for policymakers, urban planners, and financial institutions seeking to accelerate the transition towards more environmentally sustainable and resilient cities in India.

The green bond market has significantly improved in recent years thanks to the development of financial instruments and the rising climate change concerns. Given this backdrop, this paper investigates the effects of returns in different financial markets, i.e. the United States Treasury Bonds, the Standard & Poor's stock market, the United States Dollar, Gold, Crude Oil, and Bitcoin on the Green Bond returns (the Standard & Poor's Green Bond Index) from September 17, 2014, to September 1, 2022. The results from the robust linear and machine learning estimators indicate that the returns of the United States Treasury Bonds and the United States Dollar are negatively related to the Green Bond returns. Meanwhile, Gold returns positively affect Green Bond returns. The quantile regression estimations of Machado–Santos Silva also show that these findings are valid in different quantiles. The paper also discusses policy implications related to climate change and the development of financial instruments to promote green investments. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this paper is to analyze the importance of finance for climate change. Design/methodology/approach: The paper attempts to answer the question: what is the meaning of finance in the processes related to environmental protection, what is the development trend in the field of the so-called instruments of green finance and what are the purposes of the particular instruments. The following research methods were used: literature review, desk research (UNCTAD reports, GIIN, Sustainable Debt, Green Finance in Poland,) and deductive reasoning. Findings: The market for green finance instruments is growing rapidly. For both green bonds and sustainable funds and impact investments, the growth rate in the number and value of instruments has been the highest in recent years. The analysis of investment directions indicates that they are related to activities concerning environmental protection or other aspects of sustainable development. Practical implications: The importance and need for creating conditions (legislative, technical, educational) for the development of green finance instrument market was indicated. Originality/value: The paper offers cognitive value as it contributes to the body of knowledge regarding the relevance of green in addressing climate change. [ABSTRACT FROM AUTHOR]

Corporations develop, own, operate, and direct a majority of all assets in the built environment (BE), and the development and operation of these assets is a significant component of global sustainability. In recent years corporate sustainability action for large companies has trended toward becoming embedded within corporate environmental, social, and governance (ESG) programs. However, ESG strategies and their impacts are only beginning to be understood by large corporations, with little definition for how to apply, measure, and assess the effectiveness of ESG practices. Every industry sector has some connection to the BE, and construction engineering, and management (CEM) professionals contribute to all phases of the BE life cycle, including development, design, construction, and operations. As such, CEM professionals are vital in developing and implementing sustainability practices specifically for corporations with large footprints in the BE. The purpose of this research was to assess the extent to which the BE is impacted by corporate sustainability practice through ESG programs. The research utilized a grounded theory approach to explore sustainability practices directly associated with the BE from companies within all 11 Global Industry Classification Standard (GICS) sectors. It presents a representative model that encapsulates current organizational ESG strategy, through the development of ESG action categories. A total of 24 different ESG action categories are presented and defined. The research further identifies those ESG actions commonly applied by large corporations and how these actions differ by GICS sector. This research indicates that over half of corporate ESG actions are related to the BE. Ultimately, this paper demonstrates the necessary role that CEM professionals should play in influencing sustainability practice through ESG strategy and action within the BE. Practical Applications: ESG is a rising topic in corporate sustainability and is becoming increasingly tied to financial instruments such as sustainable investment indexes or green bonds. The rise of ESG presents both a challenge and an opportunity for CEM professionals. Large entities are expected to publish ESG reports sharing their sustainability progress, including entities in which CEM professionals are key figures, such as power utilities. The advent of ESG reporting presents a challenge to CEM professionals because they need to learn to navigate ESG reporting or risk losing access to valuable funding opportunities when subject to ESG measurement and evaluation. It also presents an opportunity for CEM professionals because they are uniquely qualified to lead ESG efforts as BE experts. ESG and the BE are strongly related, with most ESG work being environmental in nature. CEM professionals have been actively involved in improving the sustainability of BE assets as they relate to the environment for many years. To leverage this experience, CEM professionals need to take an active part in recommending improvements to corporate ESG strategy. Corporations themselves must also actively seek to engage CEM professionals in their ESG decision making processes and advisory boards. [ABSTRACT FROM AUTHOR]

This paper aims to effectively reduce CO2 emissions by examining the impact of three distinct incentive and constraint policies on the quality of rating and certification information in China's green bond issuance market. To accomplish this, the government has implemented incentives, while regulators have introduced constraints to curb the spread of inflated rating and certification information. We build on the integrated rating and certification regulation mechanism by presenting a two-stage Stackelberg game model that involves four key participants: the China Securities Regulatory Commission, local governments, green evaluation and certification agencies, and credit rating agencies. We incorporate environmental effects indicators into the expected utility of rating and certification agencies to investigate the equilibrium conditions under three policy scenarios: a single financial incentive policy, a single regulatory constraint policy, and a combined incentive and constraint policy. The paper employs Stackelberg game theory to analyze how different policies mitigate the occurrence of "inflated" ratings and "greenwashing" in certifications. Numerical analysis is conducted to validate the theoretical findings. Moreover, we assess the impact of these policies on the quality of rating and evaluation information, using data from China's green bond issuance market between 2016 and 2021. Our research offers valuable management insights and regulatory recommendations for both regulators and local governments. [ABSTRACT FROM AUTHOR]

This paper explores the issuance and growth of transition and sustainabilitylinked bonds into the green market segment normally reserved for green bonds between 2018 and 2021. Using a performative economics and STS approach we examine how key terms within environmental political discourse - transition, green, sustainability - have been incorporated into the operation of investment markets, and given specific, if unstable and contested, technico-economic forms. Using event ethnography, industry literature and primary interviews, we examine how classification works as a market device, by exploring why the newer 'transition bond' was favoured by some investors but not others in comparison to green and sustainability bonds. We argue that the credibility of different green labelled products is being mediated by uneven references to scientific evidence, in the context of competing marketization strategies, which have world-making effects.

The size of green bond market has been increasing rapidly since the Paris Agreement on climate change was adopted in 2015. This paper is an empirical study on the public companies that have financed greenfield projects through green bonds. The study is based on equity investor behavior following the news announcement of green bonds. An event study approach is applied to find out the impact on abnormal returns of stocks during the window period of the announcement day. The study supports that stock return behavior is positive, which is an indication that investors responded positively to the announcement of green bonds. Leverage analysis is also performed, and it is found that the financial leverage increased in the post-issue period of green bonds. It is an indication that the use of low-cost security in financing the greenfield projects is capable of maximizing shareholder returns, if the return on investment is more than the cost of green bonds. This paper adds to the existing literature as it focuses on the stock performance of public companies around green bond issuance announcement. Further, the analysis of financial leverage of the firms distinguishes this study from others. [ABSTRACT FROM AUTHOR]

This paper explores why and how green bond investors apply environmental and financial morality. It analyses the coproduction of environmental and financial values in green bond markets using digital ethnography, industry literature and interviews with investors during 2019–2022. It analyses how green bond investors explain and narrate their diverse market practices in the balancing of financial and ethical returns, converging in an unstable space of mutual coproduction. The calculative practices and signalling of green virtue are performed in little machines of ethical inscription but are rarely either empirically validated or explicitly discussed. The green bond universe might appear stable, but its foundations are forged in long-standing intersectional assumptions, as it relies on, and reproduces, the historical structures of racial capitalism. The market practices described here are designed to help green bonds become a mainstream asset class. However, these are reproducing older discursive tropes and growth is elusive.

This paper focuses on sovereign green bonds issued in Europe. By issuing green bonds, European governments commit themselves to realizing environmentally friendly projects and encourage other entities, including private-sector ones, to do the same, thus increasing further domestic investments in addressing climate change. However, considering that governments could pursue their sustainable goals by also issuing conventional bonds, this begs the question of why governments should prefer green bonds. A dataset of European sovereign green bonds was retrieved from the Bloomberg Fixed Income database to answer this question. The data cover all European sovereign green bonds issued until the end of 2023. Quantitative analysis confirms the existence of a small green premium for the issuers, representing an incentive to increase the issuances of sovereign green bonds. Furthermore, the government's carbon emissions reduction, the power sector decarbonization, and good climate policies, measured by the Government Climate Risk Score, contribute to further reducing a country's climate risk and consequently the costs of the issuance, thus triggering a virtuous circle which could, in turn, accelerate the transition to net-zero emissions. Despite these benefits, hurdles still exist, and have curbed the development of the market. Examples include divergence between the use of funds raised through green bonds, which should be earmarked exclusively for climate and environmental projects, and the fungibility requirements for proceeds from sovereign debt and fiscal revenues.

Transitioning to a low-carbon economy while promoting sustainable development requires behavioural changes and mobilization of significant investments. Key instruments being used for that include carbon pricing initiatives, such as carbon taxes and cap-and-trade policies, and, more recently, green bonds. Although the literature has provided some evidence on emission reduction associated with carbon pricing initiatives, there is a lack of investigations on the environmental performance of green bonds; and only theoretical models describe the potential benefits of combining both. Aiming to fill this gap, this study uses regression analysis and annual data for 150 countries between 1990 and 2019 to assess how carbon pricing initiatives and green bonds relate to carbon dioxide (CO2) emissions. This paper makes two main contributions. First, it examines how two climate instruments, carbon pricing and green bonds, relate to CO2 emissions. Previous research has focused only on individual instrument assessments and mainly on carbon pricing. Second, this paper empirically analyses whether there are interaction effects of the two instruments, an assessment not previously undertaken. The results suggest that the implementation of nationwide carbon pricing initiatives is associated with an 11% reduction in CO2 emissions on average. By comparison, green bond issuances are associated with an average 14% reduction in CO2 emissions. Further, no statistically significant interaction effects between carbon pricing initiatives and green bonds were observed. The results must be cautiously interpreted and cannot be attributed solely to the instruments studied since heterogeneous effects, biases from distinct sources, and the existence of complementary policies might influence the results. Carbon pricing initiatives, such as carbon taxes and cap-and-trade schemes, and green bonds are being used to promote the transition to a low-carbon economy. Investigation into green bonds and their impact on emissions is scarce and to date, only theoretical models analysed potential interaction effects of their combination with carbon pricing. The results show an average of 11% reduction in CO2 emissions associated with carbon pricing initiatives and of 14% reduction in CO2 emissions associated with green bonds issuances. While the results show promise in the emission reduction performance of these two instruments, caution in interpreting these results is advised as complementary policies, biases from distinct sources, and evidence of heterogeneous effects make it challenging to disentangle the effect of individual policies.

Value at Risk and Expected Shortfall are two traditional tools used to measure extreme risk in financial markets. However, there is little research on measuring extreme risk in emerging markets such as green bonds and clean energy. This paper uses both semi-parametric models with simultaneous excitation functions and traditional models to estimate extreme risk in SP500 Green Bond (GB) and Global Clean Energy (GCE), selecting Expected Shortfall (ES) and Value at Risk (VaR) as the indices of extreme risk. Then, the paper uses a breakpoint scan of the predictions of the different types of models. The results find that the green bond market was relatively stable while the global clean energy market experienced sharp fluctuations after the COVID-19 pandemic outbreak. Representative models in GCE have at least two breakpoints, but those for GB have no breakpoints. The GARCH model with normal innovations performs the best among all target models, and the GARCH-FZ model fits the best among all semi-parametric candidates. Our research could help governments, companies, and investors with risk management and improve model accuracy and mechanisms for measuring extreme risks. [ABSTRACT FROM AUTHOR]

Achieving the ambitious climate goals established on the international agenda for boosting sustainable development involves significant financial resources. Therefore, the funds allocated by the financial system for green investments should increase globally. Against this backdrop our paper investigates the role of multilateral development banks in promoting green finance, with focus on Romania. The research results underline their engagement to combat climate change and to support sustainable development. The European Investment Bank, The European Bank for Reconstruction and Development and the International Finance Corporation have major contributions in financing green projects in Romania in areas such as energy efficiency, green building, clean transportation, sustainable agriculture. To this end they established some partnerships with Romanian financial institutions, granted financing facilities, invested in the green bonds issued by local banks, provided technical assistance. However, our main finding shows that green finance in Romania is still limited, requiring increased commitments in this area, including from multilateral development banks. [ABSTRACT FROM AUTHOR]

The relationship between the environment and climate change on one hand and the financial system, financial regulation and monetary policy on the other is growing in importance. This paper examines the possible impact of the European Central Bank's monetary policy of quantitative easing on the environmental policy of the European Union. Using data from Climate Bonds Initiative, the paper analyses the variation in the amount of "green labelled bonds" issued in the individual member countries of the Eurozone areas, as a function of liquidity inducing monetary policy variables. The paper finds a positive and significant relationship between the two measures. [ABSTRACT FROM AUTHOR]

Africa is one of the most vulnerable continents to climate change. Climate and sustainability-linked bonds can provide funding to African governments and corporations for projects that help to mitigate climate change, combat biodiversity loss, and foster sustainable development. However, less than 0.3% of the global environmental, social, governance (ESG) bond issuance volume is devoted to projects in Africa. Based on the entire universe of 107 African ESG bonds from 42 governmental and corporate issuers over the period 2010–2023, this paper establishes that ESG bonds provide benefits to both issuers and investors in terms of lower spreads and volatility. Our econometric results highlight that greenwashing is a valid concern for investors in African ESG bonds and certification of ESG bonds makes a difference vis-à-vis the self-labeling of green bonds. Non-certified ESG bonds do not offer similar benefits compared to certified ones. Green macro-financial policy and suitable regulation to prevent greenwashing can foster African ESG-bond markets.

This paper examines the relationship between corporate governance mechanisms and their impact on green bond yield spreads for companies operating in emerging capital markets. The role of boards in mitigating ESG risks is well studied for developed countries, but there is no evidence of the impact of corporate governance on green finance for emerging capital markets. To fill in the gap, we use a unique dataset constructed with data from Thomson Reuters Refinitiv Eikon, World Bank, and Central Intelligence Agency (CIA). We study 283 green bond issues by 125 companies from 16 emerging markets with assigned ESG scores for the period between 2017 and 2022. Our findings contribute to the literature in several ways. First, we provide new evidence for the significant impact of corporate governance on green bond yield spreads in emerging capital markets. Second, we demonstrate that issuers with higher CEO power will enjoy higher green bond yields. Third, board size matters for investors in corporate green bonds from emerging capital markets and has a negative impact on the yield spread. Moreover, in the research model we account for the specific features of the country's institutional environment, such as the quality of the country's regulatory system, the capacity of the central authority and the nature of its legal system. Our findings provide evidence that only government effectiveness and rule of law indexes are significant drivers of green bond spreads, while the regulatory quality index is not.

This paper empirically assesses the performance of green bond indices and the causality of that performance using a range of financial and commodity data. We present new insights from the novel application of datasets, neural networks and performance measurements. We find that green bond indices do not outperform the market when factors beyond market return are considered. We find that Brent crude oil has the most significant effect on certain indices, a finding that contrasts with other studies on green bonds. A greater sensitivity to oil prices and global green equities also evinces a negative impact on a green bond index's ability to outperform the market. For the first time, a linear causal relationship is established between Title Transfer Facility (TTF) returns and green bond index returns. Additionally, a fundamental shift in causal relationships is observed over the COVID-19 period. In this way, we contribute to the literature on sustainable green bonds and the impact of COVID-19. These insights provide more clarity to market participants for navigating the uncertainties of both the global energy transition and the postpandemic period. [ABSTRACT FROM AUTHOR]

The "dual-carbon" strategy was first written into China's "Government Work Report" in 2021, bringing green low-carbon development and green innovation to an unprecedented height. At the financial policy level, the Chinese government actively promotes the development of a green financial system represented by green bonds, green insurance, science and technology insurance, and green credit. Existing literature studies on green insurance and science and technology insurance mainly focus on the relevant legal system, the impact on corporate and risk management system, insurance types and service models, subsidy policies, and the problems and challenges they face. However, existing studies have studied the impact of green insurance and science and technology insurance on corporate' green innovation. In particular, the impact of their interaction on corporate' green innovation is rarely mentioned. From the perspective of green insurance and science and technology insurance to promote corporate' green innovation, based on the data sample of Shanghai and Shenzhen A-share listed companies from 2014 to 2015, this paper comprehensively investigated and analyzed the impact of green insurance and science and technology insurance on corporate' green innovation, and analyzed the interaction e [ABSTRACT FROM AUTHOR]

Purpose: This study aims to investigate the impact of pollution control bonds (PCBs) on overinvestment within utility firms. Design/methodology/approach: This empirical study analyzes a data set comprising 215 US energy firms observed from 2011 to 2021, using the ordinary least square regression with standard errors adjusted for firm-level clustering. Findings: The study reveals a negative relationship between PCBs and overinvestment, indicating that PCBs are an effective tool in curbing excessive investment. Additionally, it demonstrates that chief executive officer (CEO) overconfidence diminishes the influence of PCBs on overinvestment. These findings remain robust across various metrics for measuring overinvestment and CEO overconfidence, as well as when alternative estimation methods are used. These results align with insights derived from agency theory and upper echelon theories. Research limitations/implications: Regulators are encouraged to actively promote the use of PCBs as a financing tool for environmentally focused initiatives. To achieve this, regulatory bodies should enhance their presence within the utility sector, particularly in regions grappling with higher pollution levels. This requires the implementation of strategic policies and regulatory frameworks aimed at mitigating excessive investments. Simultaneously, policymakers should take proactive measures to introduce financial instruments designed to optimize investment efficiency, thus facilitating eco-friendly projects. Originality/value: To the best of the authors' knowledge, this paper holds the distinction of being the first to examine the impact of a specific type of green bond, namely, PCBs, on overinvestment. Furthermore, it contributes to the literature on personality traits, particularly within the context of the upper echelon theory, by investigating the moderating influence of CEO overconfidence.

Investing in green bonds has been recognized as a strategy that not only promotes environmental performance but also offers attractive investment returns. However, macroeconomic factors, such as geopolitical risk (GPR), climate policy uncertainty (CPU), and global economic policy uncertainty (GEPU), play a substantial role in shaping green bond returns. Using the returns of US green bonds as a proxy for the returns of green bonds, we argue in this paper that these heterogenous uncertainty measures might have asymmetric impacts on the returns of green bonds (GB). By employing monthly data from January 2016 to August 2022, we apply the nonlinear autoregressive distributed lags model (NARDL) to examine the asymmetric impact of these heterogenous uncertainty measures on the returns of GB. The NARDL findings reveal evidence of short-run asymmetric impacts of GPR, GEPU, and CPU on the returns of green bonds. In the long run, there is an asymmetric impact of GPR and CPU on the returns of GB. However, there is a symmetric impact of CPU on the returns of GB in the long run. Specifically, in the short run, we found that a positive CPU shock causes a decline in the returns of green bonds. A similar magnitude of negative CPU shock causes an increase in the returns of green bonds. Moreover, a positive shock to GPR increases the return of green bonds, while a comparable negative shock to GPR reduces the return of GB. Furthermore, only negative shocks to GEPU have an impact on GB returns in the short run. Specifically, a negative GEPU shock reduces GB returns. In the long term, the returns of GB are positively impacted by negative shocks in GPR and both positive and negative shocks in GEPU, whereas positive shocks in GPR affect the returns of GB negatively.

Purpose: This study explores the interconnectedness and complexity of risk-varied climate initiatives such as green bonds (GBs), emissions trading systems (ETS) and socially responsible investments (SRI). The analysis covers the period from September 2011 to August 2022, using six indices: three representing climate initiatives and three indicating uncertainty. Design/methodology/approach: To achieve this, the study first examines dynamic lead-lag relations and correlation patterns in the time-frequency domain to analyse the returns of the series. Additionally, it applies an innovative approach to investigate the predictability of uncertainty measurements of climate initiatives across various market conditions and frequency spillovers in the short, medium and long run. Findings: The findings indicate changing relationships between the series, increased linkages during turbulent market periods and strong co-movements within the network. The ETS is recommended for diversification and hedging against uncertainty indices, whereas the GB may be suitable for long-term diversification. Practical implications: This study highlights the role of climate initiatives as potential hedges and contagion amplifiers during crises, with implications for policy recommendations and the asymmetric effects on market connectedness. Originality/value: The paper answers questions that previous studies have not and contributes to the literature regarding financial risk management and social responsibility. [ABSTRACT FROM AUTHOR]

Purpose: Sustainable investments (SI) represent a promising class of investments, combining financial returns with mitigating environmental challenges, achieving SDG goals and creating a positive business impact. An enhanced global focus on climate change developments in the backdrop of COP26 and COP27, raised the need for comprehensive literature mapping, to understand the emerging themes and future research arenas in this field. Design/methodology/approach: The authors apply a quali–quantitative approach of bibliometric methods coupled with content analysis, to review 1,022 articles obtained from the Web of Science (WoS) database for 1991–2023. Findings: The results identify the leading authors and their collaborations, impactful journals and pioneering articles in sustainable investment literature. The authors also indicate seven major themes of SI to be financial performance; fiduciary duty; CSR; construction of ESG-based portfolios; sustainability assessment tools and mechanisms; investor behavior; and impact investing. Further, content analysis of literature from 2020 to 2023 highlights emerging research issues to be SDG financing via green bonds and social impact bonds; investor impact creation via shareholder engagement and field building strategies; and governance related determinants of firm-level sustainable investments. Finally, the authors discuss the research gaps across these themes and identify future research questions. Originality/value: This paper crystallizes research themes in sustainable investment literature using a vast coverage of globally conducted studies published in reputed journals till date. The findings of this study coupled with future research questions provide a well-grounded foundation for new researchers to further explore the emerging dimensions of this field.
