The outbreak and the spreading of the COVID-19 pandemic have impacted the global financial sector, including the alternative clean and renewable energy sector. This paper aims to assess the impact of the pandemic, COVID-19 on the stock market indices of the clean energy sector using quantile regression methods.

This study utilized daily data sets on the four major categories of stocks: (1) Morgan Stanley Capital International Global Alternative Energy Index, (2) WilderHill Clean Energy Index, (3) Renewable Energy Industrial Index (RENIXX) and (4) the S&P 500 Global Clean Index. The study adopts a multifactor capital asset pricing model.

Clean and alternative energy stocks are powerful instruments for diversification. However, the impact of the volatility index induced by infectious disease is negative and significant across quantiles.

For investors and policymakers, considering how the uncertainty caused by COVID-19 and the geopolitical index influences renewable energy markets is of great practical importance. For investors, it throws insights into portfolio diversification. For policy makers, it helps to devise strategies to reboot the economy along the lines of the deployment of renewables. This study sheds light on a global green-energy transition and has practical implications for renewable energy resilience in post-pandemic times.

This paper can be considered as a pioneer that explores the nexus between oil prices, interest rates, volatility index, and geopolitical risk upon the stock indices of clean and alternative sources of (renewable) energy in the COVID-19 pandemic situation. The results have important insights into the area of energy and policy decision-making. Additionally, the paper's novelty lies in using the explanatory variables associated with the Covid 19 pandemic.

In an era marked by heightened geopolitical uncertainties, such as international conflicts and economic instability, the dynamics of energy markets assume paramount importance. Our study delves into this complex backdrop, focusing on the intricate interplay the between traditional and emerging energy sectors.

This study analyzes the interconnections among green financial assets, renewable energy markets, the geopolitical risk index and cryptocurrency carbon emissions from December 19, 2017 to February 15, 2023. We investigate these relationships using a novel time-frequency connectedness approach and machine learning methodology.

Our findings reveal that green energy stocks, except the PBW, exhibit the highest net transmission of volatility, followed by COAL. In contrast, CARBON emerges as the primary net recipient of volatility, followed by fuel energy assets. The frequency decomposition results also indicate that the long-term components serve as the primary source of directional volatility spillover, suggesting that volatility transmission among green stocks and energy assets tends to occur over a more extended period. The SHapley additive exPlanations (SHAP) results show that the green and fuel energy markets are negatively connected with geopolitical risks (GPRs). The results obtained through the SHAP analysis confirm the novel time-varying parameter vector autoregressive (TVP-VAR) frequency connectedness findings. The CARBON and PBW markets consistently experience spillover shocks from other markets in short and long-term horizons. The role of crude oil as a receiver or transmitter of shocks varies over time.

Green financial assets and clean energy play significant roles in the financial markets and reduce geopolitical risk. Our study employs a time-frequency connectedness approach to assess the interconnections among four markets' families: fuel, renewable energy, green stocks and carbon markets. We utilize the novel TVP-VAR approach, which allows for flexibility and enables us to measure net pairwise connectedness in both short and long-term horizons.

The purpose of this study is to evaluate the influence of sustainable business models in building corporate reputation and resilience. Specifically, the financial performance of listed companies will be evaluated following the beginning of the armed conflict in Ukraine on 24 February 2022. Taking as a standpoint the triple bottom line (TBL) theory, the case of firms listed in the Spanish IBEX-35 index is analysed. The present paper evaluates financial performance and corporate reputation, based on the usage of Environment, Social and Corporate Governance (ESG) strategies to adhere to their Corporate Social Responsibility (CSR).

To achieve this goal, energy firms operating in Spain are evaluated. Specifically, companies operating in the energy sector listed in the IBEX35, benchmark index of Spain’s largest trading platform are considered. The analysis comprises evaluating the fluctuation in the value of their stock and the influence of usage of renewable and other power sources that limit dependency on foreign events. In addition, communication and dissemination of non-financial information, and usage of international standards within these areas, are considered as well.

Results show long-term CSR commitments and ESG strategies significantly impact firm’s ability to overcome crises and improve financial performance. Additionally, energy firms that adhered to the energy transition into renewables display stronger performance and lower dependency on uncertain and weakened markets during the Ukraine armed conflict.

The results contribute to the advancement of the TBL theory and the creation of sustainable business models. By introducing ESG strategies, firms are able to improve the people-profit-planet balance and at the same time improve their resilience. This contributes to an overall enhancement of their capacity to overcome crises and sustain their financial performance and corporate reputation over time. Policy makers can also benefit from this knowledge, introducing regulation that promotes and supports companies’ development of their CSR through ESG strategies, to ensure more sustainable organisations that can support the economy in a context of hardship.

The analysis evaluates the results of a firm’s long-term commitment to the TBL through adequate ESG strategies when operating in unexpected and unprecedented hostile environments. Previous research has focused on the link between some variables concerning financial performance and ESG strategies yet not considering the specific context of an enhanced crisis (i.e. a pandemic and armed conflict). This can provide significant insight into the contribution that people, profit and planet can provide in building sustainable and successful organisations. Lastly, the paper outlines the key factors that contributed to the firm’s ability to overcome extreme hardships, such as operating in an environment affected by a combination of two crises.

This paper aims to propose a liquidity management solution for Islamic financial institutions (IFIs) that concurs with sustainable development and financial stability.

The study is a qualitative research. It uses the exploratory research methodology, specifically the content analysis approach, to gather primary data and identify and interpret relevant secondary data and Sharīʿah concepts. The purpose is to develop a liquidity management solution for IFIs. The proposal is based on the Unleveraged Green Investment Trust (UGIT) model, which is consistent with Basel III regulatory requirements. In developing the UGIT model, the exploratory research was complemented by a case study to examine the UGIT solution for the particular case of renewable energy.

The model demonstrates how financial innovation can meet both financial stability and sustainable development objectives, thereby achieving the spirit of Islamic finance. The structure further highlights the importance of regulatory and fiscal frameworks to enhance liquidity management and investor appeal for green financial instruments.

This study suggests a structure of UGIT to enable IFIs to meet their liquidity management needs while promoting sustainable development.

This study aims to assess the effect of water variation on bioethanol production from cassava peels (CP) using Saccharomyces cerevisiae yeast as the ethanologenic agent.

The milled CP was divided into three treatment groups in a small-scale flask experiment where each 20 g CP was subjected to two-stage hydrolysis. Different amount of water was added to the fermentation process of CP. The fermented samples were collected every 24 h for various analyses.

The results of the fermentation revealed that the highest ethanol productivity and fermentation efficiency was obtained at 17.38 ± 0.30% and 0.139 ± 0.003 gL⁻¹ h⁻¹. The study affirmed that ethanol production was increased for the addition of water up to 35% for the CP hydrolysate process.

The finding of this study demonstrates that S. cerevisiae is the key player in industrial ethanol production among a variety of yeasts that produce ethanol through sugar fermentation. In order to design truly sustainable processes, it should be expanded to include a thorough analysis and the gradual scaling-up of this process to an industrial level.

This paper is an original research work dealing with bioethanol production from CP using S. cerevisiae microbe.

The purpose of this paper is to propose a conceptual framework for handling end of life (henceforth EoL) scenarios of solar photovoltaic (solar PV) panels, which includes different options available to businesses and end-users, as well as promoting the collaboration between government and all relevant stakeholders.

This paper adopts purposeful sampling, secondary data and content analysis to develop an appropriate conceptual framework that helps to create awareness of the appropriate options for dealing with the EoL cases of solar PV panels.

From the data analysis, it is revealed that reuse, repair and recycling of solar PV panels can ensure value creation, public-private partnership and a solution for education in sustainability, and thus, prolonging the useful life cycle of the products.

This paper limits the analysis on developing economies and the use of selected literature based on the recycling of solar PV panels.

This paper is an initial attempt to create an awareness by identifying, analyzing and educating the stakeholders to handle appropriately any EoL scenario of solar PV panels.

Although the tasks of managing carbon peaks and achieving carbon neutrality in China are arduous, they are also of great significance, which highlights China’s determination and courage in dealing with climate change. The power industry is not only a major source of carbon emissions but also an important area for carbon emission reduction. Thus, against the backdrop of carbon neutrality, understanding the development status of China’s power industry guided by the carbon neutrality background is important because it largely determines the completeness of China’s carbon reduction promises to the world. This study aims to review China’s achievements in carbon reduction in the electric industry, its causes and future policy highlights.

The methods used in this study include descriptive analyses based on official statistics, government documents and reports.

The research results show that, after years of development, the power industry has achieved positive results in low-carbon provisions and in the electrification of consumption, and carbon emission intensity has continued to decline. Policy initiatives play a key role in this process, including, but not limited to, technology innovations, low-carbon power replacement and supported policies for low-carbon transformation toward low-carbon economies.

This study provides a full picture of China’s power industry against the backdrop of low-carbon development, which could be used as a benchmark for other countries engaging in the same processes. Moreover, a careful review of China’s development status may offer profound implications for policymaking both for China and for other governments across the globe.

Nowadays, climate change and environmental pollution have become major international concerns, in which logistics and manufacturing activities are playing the major role. In the past decade, more attention has been directed toward environmental issues than ever before. The Paris agreement is one of the most recent milestones in this regard. Due to local and international legislation, managers are highly encouraged to seek out sustainable innovations and strategies to reduce the negative impacts of their business activities. An array of academic and practical activities has been formed around the greening of the supply chain (SC). This paper attempts to review and classify green supply chain management (GSCM) disciplines and best practices from a practical point of view. The authors also investigate the different areas of application and review the GSCM practices in some well-known companies. On this basis, the paper disclose the superiority of Apple company over the other studied cases in applying green practices, particularly in the manufacturing and design areas, while the parcel delivery company has been quite active in the green transportation and green marketing. It is also shown that all of the reviewed cases have been successful in implementing green logistics initiatives thus far.

A sustainability reporting framework must demonstrate that resources are fairly bought and used to support diverse life on earth within habitable ranges. The purpose of this paper is to propose a principle-based sustainability reporting framework that measures, audits and reports based on sustainability outcomes and impacts as part of the corporate reporting framework.

This paper draws on the United Nations Sustainable Development Goals (UN SDGs) and targets for preparing a reporting framework. It uses Gaia Theory and the Theory of Distributive Justice constructs that align with sustainable development principles to delineate a reporting approach.

Frameworks that promote sustainability reporting have increasingly embraced UN SDGs but overly focus on performance promoting inter-firm comparisons. This framework introduces principle-based sustainability reporting where firms demonstrate their chosen contribution to sustainable development using 17 UN SDGs as goal posts.

This conceptual paper presents theoretical constructs that future research can empirically validate to enhance sustainability reporting.

This principle-based sustainability reporting framework is implementable for corporate reporting, where sustainability reporting integrates with the financial and economic intellectual capital reporting frameworks.

This framework highlights the importance of acquiring and using resources to distribute justice and fairness. It is a joint project between firms and stakeholders.

This framework promotes integrated thinking for firms to engage in principle-based sustainability reporting and provides a roadmap for sustainability reporting using the SDG Compass logic model.
