“…Building on the derived conclusions, this study makes three key contributions to the field. First, it extends the scope of existing research, such as that by Yang et al [17], Zheng et al [18], and Wang and Yu [19], by providing a comprehensive empirical analysis of the impacts of energy transition and digitalization on carbon dioxide emissions across 28 Chinese provinces. This regional analysis enriches our understanding of the varying impacts of the energy transition, which is crucial for creating tailored policies in different geographical areas.…”

This paper presents an empirical investigation into the effects of energy transition and digitization on carbon dioxide emissions, serving as a proxy for environmental sustainability, across 28 Chinese provinces from 2000 to 2021. Utilizing both static and dynamic regression analyses, the study reveals a significant driving effect of the energy transition on environmental sustainability, primarily through a reduction in carbon dioxide emissions. Notably, this influence is more pronounced in the eastern region of China, followed by the central and western regions, indicating regional heterogeneity in the impact of the energy transition. Furthermore, digitization is found to have a substantial moderating effect, enhancing energy conservation and emission reductions. As digitization progresses, its capability to diminish the impact of energy transitions on carbon dioxide emissions becomes more apparent, particularly in the eastern region, while this effect is less marked in central and western China. The study also delves into the nonlinear relationship between energy transitions and carbon dioxide emissions, discovering that increased levels of digitization can exacerbate the negative effects of energy transitions on emissions. These findings offer valuable insights into the dynamics of energy transition and digitalization, highlighting their crucial roles in shaping environmental sustainability in China.

“…Overall, while our study suggests that the embodied energy mix of GSC is greening, as climate mitigation is a global concern, we should further discuss whether a greener embodied energy mix will help carbon reduction. On the one hand, as the emission factor of renewable energy is lower than fossil fuel, a greener embodied energy mix will help reduce GHG emission [45] . On the other hand, as international trade leads to a separation between production and consumption, and the pace of energy transition varies across countries, countries with a greener energy mix tend not to be major participants in GSC (i.e., they are smaller players in global production and trade).…”

Energy underpins international trade, and a greener energy mix can contribute to cleaner global supply chains (GSCs). This paper examines how energy transition has influenced GSC greening through embodied renewable energy transfer. Specifically, we analyze the contribution of countries/regions and sectors to the greening process from 2011 to 2021. We find some evidence of GSC greening over the period as the ratio of renewable energy in total transferred energy increased from 4.2% to 7.6%. Emerging economies that have advanced rapidly in energy transition are gradually overtaking developed countries in their contribution to GSC greening. Sectors with a higher electrification rate are main contributors to GSC greening led by significant inter-sectoral spillovers from the heavy industry and business services. However, transfer of embodied renewable energy by high-income developed countries is concentrated in other high-income countries raising concerns of limited access by low-income developing countries and the amelioration of global energy welfare inequality.

“…One of these advantages is obtaining renewable and sustainable energy to replace fossil fuel production from oil refining, a scarce natural resource [4]. The production and use of fossil-based energy are some of the most important causes that generate global warming and its consequences, such as climate change [5][6][7]. The search, development, and implementation of clean, non-polluting, renewable, and sustainable energy production technologies, such as BRFs, are issues of vital importance worldwide to carry out the necessary energy transition that allows the reduction or mitigation of greenhouse gas (GHG) emissions that cause global warming.…”

Biorefineries (BRFs) that process the organic fraction of municipal solid waste and generate bioproducts and bioenergies have attracted attention because they can simultaneously address energy and environmental problems/needs. The objective of this article was to critically review the microbial production of hyaluronic acid (MPHA) and its production profile for its integration into a GBAER-type BRF (a type of BRF based on organic wastes) and to identify the environmental and economic sustainability aspects of the modified BRF that would confirm it as a sustainable option. It was found that the MPHA by selected strains of pathogenic Streptococci was moderate to high, although the trend to work with genetically transformed (GT) (innocuous) bacteria is gaining momentum. For instance, A GT strain of Corynebacterium glutamicum reached a maximum HA production of 71.4 g L−1. MPHA reports that use organic wastes as sources of carbon (C) and nitrogen (N) are scarce. When alternative sources of C and N were used simultaneously, HA production by S. zooepidemicus was lower than that with conventional sources. We identified several knowledge gaps that must be addressed regarding aspects of process scale-up, HA industrial production, economic feasibility and sustainability, and environmental sustainability of the MPHA.
