Smart cities are a way for China to construct an innovative and environmentally conscious nation. The paper examines the impact of smart cities on corporate green governance and provides a theoretical foundation for formulating and executing smart city policy in China. Based on panel data from Chinese A-share listed companies in Shanghai and Shenzhen from 2008 to 2020, this study constructs a multiperiod double-difference model to examine the influence of smart cities on corporate green governance. Additionally, it uses a spatial double-difference model to investigate the spatial spillover effect of smart cities on neighboring areas. The findings indicate that smart cities effectively enhance corporate green governance. Analyzing the influencing mechanisms reveals that resource allocation efficiency, technological innovation, management environmental awareness, and regional environmental enforcement efforts act as mediators. Furthermore, the study reveals that the impact of smart cities on promoting corporate green governance is more pronounced in regions with lower levels of marketization and resource-based cities. Moreover, the research explores the spatial spillover effects of smart cities, with an effective radius of approximately 350 km. The optimal spatial correlation zone for green governance of businesses in neighboring areas in relation to smart cities is within a range of 250–350 km. This is manifested by the significant promotion of green governance in neighboring area businesses facilitated by smart cities.

The promotion of energy efficiency (EE) helps address energy constraints and promote environmental sustainability. This study comprehensively explores the spatiotemporal variations, influencing factors, and configuration promotion paths of EE in 284 Chinese cities during 2003‒2019 using the global super-efficiency minimum distance to strong efficient frontier (G-S-MinDS), exploratory spatial data analysis (ESDA), multiscale geographically weighted regression (MGWR), and fuzzy set qualitative comparative analysis (fsQCA) methods. The findings are: ① China’s cities have an annual average EE of 0.658 with a growth rate of 0.53%, showing considerable promotion potential. ② Industrial structure optimization, population agglomeration, economic development, and increased green coverage contribute positively, while government intervention and openness hinder China’s urban EE. ③ Four configurational promotion paths for enhancing China’s urban EE are identified, where among those paths population density is a core condition, while government intervention is not. This study provides valuable insights into substantially improving urban EE, emphasizing the need for targeted policies to address energy and environmental crises in China.

Carbon peak and carbon neutrality (dual-carbon) are important targets for the international response to climate change. The Silk Road Economic Belt is a strategic resource region and is important for future ecological environment and tourism development. Based on the “dual-carbon” targets, the Single index quantification, Multiple index synthesis, and Poly-criteria integration evaluation model were used in this study to measure the coordinated development index of the ecological environment, public service, and tourism economy along the Silk Road Economic Belt and to analyze its spatial and temporal evolution. Further, it explores the dynamic evolution and development trend of the three systems using the Kernel Density and Grey Markov Prediction Model. The results show that the coordinated development index along this region needs to be improved during the study period. Furthermore, the coordinated development index of the Southwest region is relatively higher than that of the Northwest region. From the development trend of the three systems, all of them develop in a stable manner; however, the tourism economy system is easily affected by external disturbances. The coordinated development index of the three systems changes dynamically and tends to be in a good state of coordination. There is a certain spatial and temporal heterogeneity. The gravity center of the coordinated development index has been in the Southwest region. During the forecast period, the coordinated development index along this region will improve significantly, while insufficient and unbalanced development will continue.

The discharge of nuclear-contaminated water containing radionuclides into the ocean by Japan will lead to its integration into the entire ecosystem through processes of circulation and biomagnification, eventually entering the human body via the food chain. This poses a substantial risk of irreversible damage to both the ecosystem and human health, a situation that will worsen with the ongoing discharge of such water. The respect and protection of human rights represent an international consensus, and safeguarding fundamental human rights is a substantial obligation that states must undertake in accordance with both international and domestic law. Since the Fukushima nuclear disaster, Japan has continuously violated its international legal obligations to protect human rights in several areas, including the resettlement of disaster victims, the reduction of nuclear radiation levels, and the handling of contaminated water. Such actions have compromised and will continue to compromise the basic human rights of not only its citizens but also those of people worldwide, including environmental rights, the right to life, development rights, and food rights. In the aftermath of the Fukushima meltdown, the public and workers involved in handling nuclear contaminants have been continually exposed to high radiation levels, endangering their rights to life, development, and health. Japan’s inadequate efforts in victim resettlement and environmental restoration have jeopardized the environmental and food rights of its citizens to live healthily and access food in an environment unaffected by nuclear radiation. The release of nuclear-contaminated water poses a risk of Japan’s nuclear pollution to the people of neighboring countries and the global population at large. The principle of human rights underpins the theory of a community with a shared future for humanity, and human rights are a crucial area of China’s active participation in United Nations affairs and global governance. By voicing concerns over Japan’s potential human rights violations globally, China demonstrates its role as a responsible major country. In response to Japan’s breach of legal obligations and human rights violations, China can adopt a reasoned and beneficial approach, including calling on the international community to hold Japan criminally accountable for crimes against humanity under the Rome Statute and advancing scholarly discussions on ecocide and crimes against the marine environment. Furthermore, China should persist in seeking advisory opinions from the International Court of Justice and strive for substantive accountability, utilizing the mechanisms of international human rights organizations to make its voice heard.

The Japanese government’s unilateral decision to discharge the nuclear-contaminated water from the Fukushima nuclear power plant into the ocean has caused immense nuclear safety risks. Monitoring the unclear-contaminated water is a starting point to combat these risks and seek remedies for the rights and interests of all concerned parties. The establishment of a mechanism for international cooperation in this respect is necessary to handle the risks of the Fukushima nuclear-contaminated water and to lay the foundation of a framework for tackling any future disposal of nuclear-contaminated water following Japan’s example. At present, the international legal systems in the spheres of nuclear safety and security, marine environmental protection, and other areas, as well as the questioning of the monitoring reports of the International Atomic Energy Agency (IAEA) by the relevant parties, the monitoring practices of historical nuclear accidents, and numerous radioactivity monitoring mechanisms have provided the institutional and practical basis for constructing such a mechanism. The mechanism can be promoted by the IAEA through its existing mechanisms or be jointly initiated by China, the Russian Federation, the Republic of Korea, the Democratic People’s Republic of Korea, and the Pacific Island countries, among other stakeholders. Specifically, this mechanism should consist of three levels: first, the framework of the basic legal system, including the cooperative principles of national sovereignty, interest-relatedness, and procedural fairness, and the signing of the Framework Convention on the Monitoring of Fukushima’s nuclear-contaminated water and its Optional Protocol; second, the organizational structure and its responsibilities, which may include the Conference of Parties as the decision-making body, the Secretariat as the central coordinating body, and the monitoring committees in various fields as specific implementing agencies; and third, specific administrative arrangements, which involve the standardization of monitoring, the management system of monitoring networks and stations, the rules for monitoring procedures, and the rules for the utilization of the monitoring data, etc. With the urgent need for the scientific and fair monitoring of Fukushima’s nuclear-contaminated water, China, as a stakeholder country, can promote the establishment of such a mechanism for monitoring nuclear-contaminated water through the following paths: ① It is necessary to clarify the factors affecting the construction of an international cooperation mechanism for monitoring nuclear-contaminated water so as to ascertain the standpoints of the stakeholders, claims of their interests, contents of their cooperation, and the relevant international relations. ② On the basis of existing practices, China should consider improving the monitoring mechanism to cope with the risks of the discharge of Fukushima’s nuclear-contaminated water by formulating targeted po
