This study examines the impact of energy-related uncertainty on idiosyncratic volatility (IVOL) in Chinese firms, leveraging data from the Shanghai and Shenzhen stock exchanges between 2007 and 2022. Utilizing the Energy-Related Uncertainty Index (EUI) and the Fama–French five-factor model, we analyze a comprehensive dataset of 20,998 firm-year observations to understand how macroeconomic uncertainties specific to the energy sector influence firm-specific risk. Our findings reveal that a one-unit increase in the EUI is associated with a 5.1% rise in idiosyncratic volatility across all firms, underscoring the significant impact of energy-related uncertainty on firm-specific risks. The effect is more pronounced in energy-related firms, where a one-unit increase in the EUI leads to a 6.4% increase in IVOL, compared to a 3.7% increase in non-energy-related firms. By incorporating industry-wise, heterogeneity, and phase-based analyses, our findings reveal significant variations in the EUI’s impact across energy and non-energy sectors. State-owned enterprises, firms with high ownership concentration, and smaller firms are more vulnerable to energy uncertainties. Additionally, the effect of the EUI on IVOL is more pronounced during periods of high uncertainty. These insights have important implications for sustainable investment strategies, risk management, and policymaking, providing a deeper understanding of the intricate dynamics of energy markets in fostering sustainable economic growth and development.

Although the existing literature on environmental sustainability (ES) emphasizes its importance, yet few empirical studies look at the major contributing variables to ES. Therefore, we examine how the use of renewable energy, globalization, and technological innovation (TI) contribute to ES, with the moderating influence of foreign aid, spanning the period from 1996 to 2019 in BRICS economies. For data analysis, we apply the ARDL methodology, revealing an adverse and substantial link among globalization, TI, and the consumption of renewable energy with ES. Additionally, we discover that foreign aid has a beneficial moderating effect on the association between ES, globalization, and TI. On the other hand, it is found that foreign aid has an adverse moderating impact on the link between renewable energy sources and ES. This research also yields crucial practical implications, offering in-depth insights for the design of more effective policies to foster economic growth.

Carbon emissions from anthropogenic human activities are viewed as the major cause of pollution in the environment. The Paris Treaty came into effect to help minimize the galloping rate of global ecological pollution. The surge in global emissions has prompted other nations to change their environmental regulations to help them to attain their emission mitigation agenda. For instance, China, United States and India have improved their Nationally Determined Contributions they pledged as signatories to the Paris Accord to help them to achieve their sustainable development goals But, despite nations committing to the guidelines of this accord, ecological contamination continues to rise in the globe. To help curb the above menace, a study on the connection between financial development, urbanization, economic growth, renewable energy consumption, and environmental quality of 27 countries from North, South and East Africa over the period 1990 to 2019 was conducted. In attaining this goal, econometric techniques that are robust to heterogeneity and residual cross-sectional dependence were deemed appropriate. From the preliminary analysis, the panel was heterogeneous and cross-sectionally dependent. Also, all the series were stationary after first difference and cointegrated in the long-run. On the regression estimates via the common correlated effects mean group technique, financial development improved environmental quality in the North, South and Eastern regions by 0.56%, 0.42%, and 0.44% respectively. Also, renewable energy promoted ecological safety in the Northern and Eastern regions by 0.24% and 0.08% respectively, but degraded environmental sustainability in the Southern region by 0.66%. Besides, economic growth deteriorated the environment in the North by 0.66%, South by 0.41%, and East by 0.25%. However, urbanization enhanced ecological safety in the East by 0.63%, but had immaterial effect on environmental quality in the North and Southern regions of Africa. Some of the aforestated results are consistent to those under the dynamic common correlated effects mean group (DCCEMG) technique as an alternative estimator. Policy recommendations to help advance the carbon-neutrality target of the regions were proposed.

Recently, there has been growing recognition of the significance of environmental, social, and governance (ESG) factors in assessing a company’s performance and worth. Previous research has failed to take into account the significant impact of technological innovation in their empirical investigations. This study fills the gap by investigating the moderating impact of technological innovation on ESG performance and company value in developing and least-developed countries. The study utilized secondary data from 78 pharmaceutical companies from 2009 to 2022. For the investigation, we used the pooled mean group (PMG) and generalized methods of moments (GMM) estimators. The findings reveal that environmental and social performance influence firms’ value; however, governance performance does not influence firms’ value. Additionally, technological innovation acts as a catalyst, strengthening the favorable influence of ESG performance on firm value. The findings affirm the need to incorporate technological innovation, as it enables pharmaceutical firms to implement more efficient and sustainable practices.

This paper investigates the impact of board characteristics (such as board size, board independence, CEO Duality, board meetings, and committee) on corporate sustainability reporting (CSR) in China. Unlike previous studies, we examine this relationship in light of the three pillars of corporate sustainability reporting: economic, environmental, and social. Using both the Fully Modified Ordinary Least Square (FMOLS) and Dynamics Ordinary Least Square (DOLS) empirical models, our data, which comprises 9842 firm-year observations from both the Shanghai and Shenzhen stock exchanges covering the 2006–2019 fiscal periods, reveals that board independence, a larger board size, and a board sustainability committee promote CSR in the three CSR pillars. However, the study shows that CEO duality is more likely to impede CSR. While the current study seems to provide some understanding regarding the relationship between board characteristics and corporate sustainability reporting to corporate boards, regulators, and practitioners interested in advancing the course of CSR, some significant knowledge gaps still need to be explored in future studies. Future research may consider other board characteristics as well as explore other CSR indices like integrated reporting and triple-bottom-line approaches.

The global energy transformation is moving forward slowly, along with the continent of Africa. Although the momentum developed thus far is encouraging, there is an increasing need for transformative solutions to lessen climate change and its effects on the continent. In this article, we analyze the connection between green growth, entrepreneurship, and their effects on sustainable development in South Africa using the Quintuple Helix Innovation Model (QHIM). Hence, the purpose of the study is to foster the need for entrepreneurship and green growth for sustainable development. The quintuple helix model’s (QHIM) theoretical premise that the natural environment of society and the economy are the two fundamental factors behind innovation and the understanding that a knowledge economy requires sustainable growth are mainly supported by our findings. We accomplish this study by determining which entrepreneurial and green growth dimensions should be prioritized, respectively. Using ordinary least squares (OLS) and generalized linear model (GLM) we examine the association. We measured green growth with two main indicators which are environmental resource productivity and natural capital. Entrepreneurship was measured using entrepreneurial activity and entrepreneurial attitudes. Our findings revealed that more attention needs to be geared towards natural capital and entrepreneurial activity in South Africa. Decision-makers and the government will utilize the study’s findings as a guide for the zealous implementation of stated policies; recommendations are also highlighted in this study.

Carbon neutrality is a 21st-century priority area, with the Middle East and North Africa (MENA) countries making significant investments in renewable energy and climate mitigation initiatives to attain it. However, carbon neutrality research in the MENA region is under-developed, particularly when considering the roles of renewable energy, economic growth, and effectiveness of government. To address this gap, this research investigates the roles of renewable energy, economic growth, and government effectiveness toward the MENA region’s carbon neutrality goal. We implemented heterogeneous and second-generation panel data techniques that are resilient to cross-sectional dependency and slope heterogeneity to panel data spanning 16 MENA countries from 1996 to 2018. We discovered that MENA data are cross-sectionally dependent, heterogeneous, and cointegrated. We found that government effectiveness and renewable energy bring carbon neutrality closer, but economic growth initially delays it. We detected Environmental Kuznets Curve (EKC) in the MENA region, specifically in the High-Income Countries. Although there were signs of EKC in the Middle-Income Countries, this was not significantly validated. Finally, we found a one-way causal link from government effectiveness and renewable energy to carbon neutrality but a feedback mechanism between economic growth and carbon neutrality in the MENA region. As a result of these findings, it is recommended that the MENA region’s policymakers prioritize renewable energies and improve the effectiveness of government to drive economic growth toward the carbon neutrality goal.

Environmental expenditures (EX) are made by the government and industries which are either long-term or short-term investments. The principal target of EX is to eliminate environmental hazards, promote sustainable natural resources, and improve environmental quality (EQ). Thus, this study looks at the impact of economic growth (EG), and government finance expenditure (GEX) on EQ in Northern Africa and Southern Africa (NASA) republics from 2000–2016. The panel quantile regression (PQR) and panel vector autoregressive (PVAR) model in a generalized method of moment framework (GMM) were employed as a framework. The PQR results show that; (i) In Northern republics, GEX had a significant positive effect on EQ at 25%, 50%, and 75% quantiles levels. (ii) In the Southern republics, GEX had a significant negative impact on EQ at 25%. Moreover, the PVAR through the GMM established that EG and GEX are significantly positive while the parameter for CO₂ is insignificant and negative in the North. However, in the South, GEX and CO₂ were statistically significant, while EG positively impacts EQ. Lastly, the granger causality report in North indicates uni-directional causation running from LNGEX → LNGDPpc, LNCO₂ → LNGDPpc, LNFF → LNGEX, and LNFDI → LNGEX. Similarly, there is uni-directional causation in South republics from LNGEX → LNGDPpc, LNCO₂ → LNGEX, and LNFDI → LNGEX.

Small- and medium-sized enterprises (SMEs) play an important role in sustainable development not only for their significant contribution to China's economy but also for their large share of total discharged pollutants. Despite the widely acknowledged importance and benefits of environmental management accounting (EMA), the level of adoption and implementation of EMA practice is still weak within SMEs in many countries, especially in China. The current systematic review aims to identify the barriers affecting the Chinese SMEs for adopting EMA practices along with the critical success factors required for adopting EMA practices by SMEs and their top management for ensuring sustainable corporate environmental performance in China. The study is carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. In total, 73 articles were found to be eligible to be included in the systematic review, which was published on EMA in small- and medium-sized enterprises in China. Our study aims to document barriers to the adoption of EMA among Chinese SMEs. The review concluded that strict legislation and the availability of flexible financing options for SMEs can promote the adoption of EMA by SMEs. The establishment of environmental reporting systems and auditing mechanisms can further increase the utilization of EMA by small and medium firms. Barriers to EMA adoption can be mitigated after careful consideration of the current situation in SMEs. Documentation of significant barriers may help to form supportive policies which ultimately add to the efforts toward climate change mitigation.
