“…A way of reducing carbon emission is to implement smart energy systems. Important technologies and current developments of those smart systems and their impact on carbon emission are shown in a study by Zhu et al [34]. Ahmed and Sarkar [1] have shown that if the cumulative expenditure under a carbon emission constraint of a sustainable manufacturing system is calculated, the cost is minimal.…”

Smart manufacturing systems should always aim to be fully sustainable while simultaneously being as reliable as possible which is difficult to reach. Furthermore, climate change especially by carbon emission ejection in the industry is a significant topic and carbon emission ejection should be controlled and reduced to save the environment. Contributing towards a greener environment in a positive manner is done by reducing the amount of insufficient items that are produced in a smart production system which also can be reached with a higher reliability in the system. Therefore, this study models a smart reliable production system with controlled carbon ejection. To solve the proposed smart production system in this study, a geometric programming approach with a degree of difficulty level two is used which results into optimum results that are quasi-closed. Furthermore, numerical experiments are conducted in order to validate the proposed model and prove that by using a higher degree geometric programming approach, an optimal solution is found. The numerical results do not only show optimal solutions but also that the smart production system with controlled carbon ejection is reliable.

Recent developments in attaining carbon peaks and achieving carbon neutrality have had enormous effects on the world economy. Digitalization has been considered a viable way to curtail carbon emissions (CE) and promote sustainable economic development, but scant empirical studies investigate the link between digitalization and CE. In this context, this study constructs the digitalization index using the entropy value method and spatial Markov chain, and the spatial Durbin model is employed to analyze its impact mechanism and influence on urban CE in 265 prefecture-level cities and municipalities in China from 2011 to 2017. The results indicate that: (1) The overall development level of the digital economy (DE) posed a significant spatial effect on urban environmental pollution. However, the effect varies according to the different neighborhood backgrounds. (2) The DE impedes urban environmental deterioration directly and indirectly through the channels of industrial structure, inclusive finance, and urbanization. (3) The development of the DE significantly reduces pollution in cities belonging to urban agglomerations, while the development of the DE escalates emissions in nonurban agglomeration cities. Finally, based on the results, important policy implications are put forward to improve the environmental quality of cities.

“…For example, under the unified planning of the government, China has built large‐scale wind and solar power plants by reform the energy system and resource assessment. 23 India stimulates industrial development through “green tariffs” and other relevant green policy support, and has formulated a detailed development plan for the development of solar energy. 24 The Korean government proposed the “re 3020 plan”, which plans to make renewable energy power generation account for 20% of the total power generation by 2030.…”

“…The development of renewable energy also can contribute to economic growth, promote local socio‐economic development, better protect the environment, and work with the world to curb global warming. For example, under the unified planning of the government, China has built large‐scale wind and solar power plants by reform the energy system and resource assessment 23 . India stimulates industrial development through “green tariffs” and other relevant green policy support, and has formulated a detailed development plan for the development of solar energy 24 .…”

By collecting and sorting the energy demand data of developing and developed countries, this paper makes a comprehensive analysis of their energy demand, including the change of energy demand and the change trend of energy load in various sectors. The survey scope of the article includes the overall change trend of energy supply, natural gas, oil, electricity, coal, renewable energy (such as wind energy, solar energy, geothermal energy, tidal energy, etc.), and the data change of global carbon dioxide emission. Besides, this paper selects a variety of energy sources for comprehensive analysis to analyze the existing change trend in chronological order. The analysis methods include data statistics of primary energy production and consumption, energy intensity analysis of gross domestic product (GDP), production, and demand balance of oil, natural gas, and coal, and study the trade balance between different types of energy in different countries and regions. The regions examined in this review include the organization for economic cooperation and development (OECD); the group of seven (G7); Brazil, Russia, India, China and South Africa (BRICs); the European Union; Europe; North America; the Commonwealth of Independent States (CIS); Asia; Latin America; the Pacific Ocean; the Middle East and Africa. By studying these data, we can make a better summary of the current energy use, so as to conveniently grasp the context of energy development and have a general understanding of the current energy structure. Therefore, individuals and policymakers in the fields of energy trade can think more deeply about the future situation and draw conclusions.
