Graphene, an innovative nanocarbon, has been discovered as a significant technological material. Increasing utilization of graphene has moved research towards the development of sustainable green techniques to synthesize graphene and related nanomaterials. This review article is basically designed to highlight the significant sustainability aspects of graphene. Consequently, the sustainability vision is presented for graphene and graphene nanocomposites. Environmentally sustainable production of graphene and ensuing nanomaterials has been studied. The formation of graphene, graphene oxide, reduced graphene oxide, and other derivatives has been synthesized using ecological carbon and green sources, green solvents, non-toxic reagents, and green routes. Furthermore, the utilization of graphene for the conversion of industrial polymers to sustainable recycled polymers has been studied. In addition, the recycled polymers have also been used to form graphene as a sustainable method. The implication of graphene in the sustainable energy systems has been investigated. Specifically, high specific capacitance and capacitance retention were observed for graphene-based supercapacitor systems. Subsequently, graphene may act as a multi-functional, high performance, green nanomaterial with low weight, low price, and environmental friendliness for sustainable engineering and green energy storage applications. However, existing challenges regarding advanced material design, processing, recyclability, and commercial scale production need to be overcome to unveil the true sustainability aspects of graphene in the environmental and energy sectors.

The freight transport chain brings together several types of players, particularly upstream and downstream players, where it is connected to both nodal and linear logistics infrastructures. The territorial anchoring of the latter depends on a good level of collaboration between the various players. In addition to the flow of goods from various localities in the area, the Autonomous Port of Lomé generates major flows to and through the port city of Lomé, which raises questions about the sustainability of these various flows, which share the road with passenger transport flows. The aim of this study is to analyse the challenges associated with the sustainability of goods flows. The methodology is based on direct observations of incoming and outgoing flows in the Greater Lomé Autonomous District (DAGL) and semi-directive interviews with the main players in urban transport and logistics. The results show that the three main challenges to the sustainability of goods transport are congestion (28%), road deterioration (22%) and lack of parking space (18%).

The pursuit of good governance by companies confronts a fundamental challenge: defining what constitutes “good governance”. Existing corporate governance codes and their implementation documents fall short of offering a clear answer to this crucial question. Despite the establishment of a reference framework years ago, the focus has shifted from defining the objectives of good governance to a consensus on the means of achieving these objectives. Unfortunately, this consensus often absolves stakeholders from providing detailed explanations. Achieving effective good governance necessitates a shift in focus towards the underlying goals of governance structures. Two potential approaches emerge in this context. While many companies rely on codes without explicitly outlining their objectives, there is a compelling case for urging or mandating them to articulate the purposes of the governance methods they employ in their reports. This level of specificity has the potential to enhance the reflective qualities of the transparency process, fostering a more comprehensive understanding of the governance landscape. Beyond merely discussing the objectives of corporate governance, the pursuit of good governance necessitates the implementation of instruments whose efficacy transcends reliance solely on market discipline. The aim is not to undermine the imperatives of transparency and justification. Instead, the intention is to recognize that these elements, while essential, do not independently ensure the effectiveness of soft law instruments, such as governance codes. Nowadays, it is crucial to assess the extent to which traditional corporate governance codes respond to the needs of companies in the era of digitalization and sustainability. Therefore, conducting a critical analysis of the existing corporate governance codes will contribute in shedding light on the gaps of these instruments to come up with recommendations for improvements. Aims and objectives: This article will focus on the following areas: Defining the role and purpose of corporate governance codes in enhancing corporate performance and accountability and discussing the challenges and limitations of corporate governance codes, including compliance issues and enforcement challenges. Presenting empirical evidence on the impact of corporate governance codes on corporate behavior and analyzing, through the principle of comply or explain, whether code adherence leads to improved corporate governance practices and financial performance. Discussing emerging trends in corporate governance and offering recommendations for improving the effectiveness of corporate governance codes.

It is important for society to know the actions implemented by companies in the construction sector to reduce the environmental pollution generated by this industry and to contribute to the solution of economic and social problems in their environment; however, the variables that allow identifying their contributions and impacts are not known. Based on this problem, the study focuses on identifying the factors that influence sustainability management within the construction sector in Colombia. The research presents a predictive approach and uses a quantitative methodology, applying statistical modeling techniques. The sample corresponds to 84 Colombian companies. As a result, a system of equations of the form y=mx+b is presented to describe the deviation of the environmental, economic, social, compensation measures, management, indicators and sustainability reports. The analysis of the intersections constitutes a projective tool to evaluate the relationships and balance points between the dimensions analyzed, helping to identify strengths and opportunities for improvement.

How can social enterprises implement Total Quality Management (TQM) to tackle urgent social issues within their organizational framework while also ensuring their continued viability? To address this question, this study aims to explore the organizational approach to the adoption and implementation of TQM practices and their efficacy in mitigating pressing social challenges and maintaining financial sustainability. It adopts a qualitative multiple-case research design involving 3 social enterprises to explore the research phenomenon. Following qualitative research analysis process using NVivo, our findings highlight a prevalent, short-term outlook in managing TQM, hindering the full potential of TQM to achieve both social impact and organizational sustainability. More specifically, they expose a significant dissonance within the case organizations’ TQM implementations: the contrast between the current state, indicative of what it is, and the ideal state, indicative of what it should be. Altogether, the study advocates leveraging TQM for long-term excellence and alignment in social enterprises (as opposed to short-term mediocrity and disarray), thereby facilitating the achievement of both social impact and financial sustainability.
