With the rapid growth of global energy demand, the fossil fuel-dominated electric power industry has led to serious environmental problems. Tradable green certificates (TGC) and carbon emission trading (CET) have become key mechanisms for promoting sustainable development of the electricity market by serving as market-oriented policy tools. To deeply analyze the impact of TGC and CET on the sustainable development of China’s electricity market and provide a scientific basis for policymakers. This study uses system dynamics (SD) methods to construct a policy synergy analysis framework for TGC and CET. It explores the impact mechanism of dual policy incentives on the sustainable development of the electricity market. Firstly, the current application status of TGC and CET in China was reviewed. Based on the literature analysis, identify key factors that affect the sustainable development of the electricity market. Then, by deconstructing the interaction between TGC policy and CET policy, an SD model was established that includes multidimensional feedback such as policy, technology, funding, and market, and the dynamic functional relationships in the SD model were quantified. Finally, Vensim PLE software 7.3.2 was used to simulate the evolution of sustainable development in the electricity market under different policy scenarios. The research results indicate that (1) the adjustment of the TGC quota ratio can change the supply and demand mechanism to form a price leverage effect, effectively stimulate the growth of renewable energy generation capacity, and accelerate the low-carbon transformation of power enterprises; and (2) the CET market changes the cost structure of power generation through carbon price signals. When the carbon emission cap target tightens, CET prices quickly rise, leading to a significant trend of carbon reduction in the electricity market; (3) the application of policy combinations can significantly promote the sustainable development of the electricity market, but the unreasonable setting of policy parameters can trigger market risks. Therefore, policy design should focus on flexibility and implement appropriate policy combinations at different stages of electricity market development to promote green transformation while ensuring smooth market operation. This study innovatively reveals the synergistic effect of TGC and CET in the sustainable development of the electricity market from a systems theory perspective. The research results provide a scientific basis for decision-makers to formulate policy adjustment plans and have essential reference value for achieving the dual goals of energy structure transformation and electricity market stability.

To achieve the dual carbon goals, countries are transforming their energy structures, with green electricity trading playing a pivotal role in this transition. This paper first analyzes the mechanisms and current state of green electricity trading. A bibliometric analysis was conducted using the keywords “green power” and “green electricity” on 2427 articles from the Web of Science core database (1984–2024). CiteSpace software 6.3 R1 was used to analyze publication volumes, contributing countries, and co-citation patterns of cited references, highlighting foundational research in this field. A deeper analysis of recent five-year trends reveals a focus on renewable energy, low-carbon policies, and the relationship between the green electricity economy and environmental development. This study finds that green electricity trading has become a growing theoretical research hotspot. Practically, China’s green electricity trading has made significant progress but still encounters challenges, such as insufficient operational mechanisms, technical barriers to grid integration, and obstacles in international green certificate trading. Based on the findings, targeted recommendations include enhancing market synergies, refining tariff mechanisms, and streamlining the trading process to support the sustainable growth of the green electricity market. This study highlights that green electricity trading is an emerging research focus, though its supporting infrastructure remains underdeveloped. Moving forward, enhanced policy support and increased R&D investment in renewable energy are urgently needed, particularly for advancing grid integration technologies for distributed energy. Additionally, aligning green electricity policies with broader low-carbon policies is essential. Furthermore, attention should be paid to the coordination between green electricity trading, economic development, and environmental protection. Full article

To ensure a smooth transition towards peak carbon emissions and carbon neutrality, one key strategy is to promote a low-carbon transition in the energy sector by facilitating the coordinated development of the electricity market, carbon market, and other markets. Currently, China’s national carbon market primarily focuses on the power generation industry. High-energy-consuming industries such as the steel industry not only participate in the electricity market but also play a significant role in China’s future carbon market. Despite existing research on market mechanisms, there remains a significant research gap in understanding how steel enterprises adjust their trading behaviors to optimize costs in multi-market coupling contexts. This study employs a system dynamics approach to model the trading interconnection between electricity trading (ET), carbon emission trading (CET), and tradable green certificates (TGC). Within this multi-market system, thermal power enterprises and renewable generators serve as suppliers of carbon allowances and green certificates, respectively, while steel companies must meet both carbon emission constraints and renewable energy consumption obligations. The results show that companies can reduce future market transaction costs by increasing the proportion of medium to long-term electricity contracts and the purchase ratio of green electricity. Additionally, a lower proportion of free quotas leads to increased costs in the carbon market transactions in later stages. Therefore, it is beneficial for steel companies to conduct cost analyses of their participation in multivariate market transactions in the long run and adapt to market changes in advance and formulate rational market trading strategies.

This study explores the impact mechanism of government environmental regulation on consumers’ green purchase intention through green consumer orientation (GCO) using Zespri as a case study. By integrating the Theory of Planned Behavior (TPB) and the Value–Belief–Norm (VBN) theory, a comprehensive framework was developed. A total of 857 valid questionnaires were collected, and Structural Equation Modeling (SEM) was applied for empirical analysis. The results indicate that government environmental regulation significantly enhances the three dimensions of GCO (identification, equilibrium, and interaction) and positively influences green purchase intention. Policy recommendations are proposed, including improving green certification systems and encouraging enterprises to adopt green marketing strategies. The findings provide theoretical and practical implications for policymakers and companies aiming to promote sustainable consumption and green supply chains. Full article

Green hydrogen is a promising energy vector for industrial applications. However, hydrogen leaks can occur causing greenhouse effects and posing safety risks for operators and local communities, potentially leading to legal liabilities. Industry 4.0 focuses on digital industrial modernization, while Industry 5.0 emphasizes collaborative, human-centered, and sustainable processes. This study developed and analyzed an Industry 5.0 proof of concept as an additional safety layer for hydrogen leak management. The proof of concept was implemented using Raspberry Pi microcomputers, integrated computer vision, and OpenAI GPT-3 for dynamic email communication. A legal liability analysis for Chile and Spain identified potential challenges in transitioning the system into a market-ready product. The findings suggest the system should act as a complementary safety layer rather than a primary detection system to mitigate legal liability risks, as operational deployment without full certification and validation could lead to malfunctions. This study illustrated how hydrogen detection and management can be integrated into Industry 5.0 smart systems. With growing global interest in sustainable engineering and AI regulation, as reflected in Regulation (EU) 2024/1689, legal considerations over technologies like the one presented in this study are becoming increasingly relevant.

To promote the low-carbon energy transition, China is implementing renewable energy (RE) development policies such as renewable portfolio standards (RPSs), carbon emissions trading (CET) and China certified emission reduction (CCER) trading. However, using China’s current CET price to accurately reflect market information is difficult, which is not conducive to guiding low-carbon investment. Additionally, as RE power enters the era of grid parity, more revenues are needed to maintain generator operations. Therefore, in this study, we construct a system dynamics model to explore whether and how market mechanisms can optimize the power generation structure, and sensitivity analyses of CCER policy parameters are carried out to identify the impact and scope for improvement. The results show that (1) the market mechanism, especially the RPS mechanism, adjusts the profits of power generators, eliciting a surge in RE generation and optimizing the power generation structure; (2) CET and CCER prices change in the opposite direction of tradable green certificates (TGCs) and show a significant improvement effect on the on-grid electricity price; (3) successful implementation of the CCER mechanism can effectively energize the CET market. A lower CCER benchmark price, higher CCER offset ratio and CET fines can accelerate the growth of CCER and CET prices. Therefore, the government should promote TGC separation from power trading and rationally design CCER policies by lowering the CCER credit ratio, increasing CET fines, and expanding CCER market capacity to ensure that the guiding role of the market mechanism is better utilized.

With the growing emphasis on sustainable development, the impact of customer environmental performance on innovation activities has attracted more attention. Using a dataset of Chinese A-share listed companies from 2009 to 2022, this study empirically investigates the relationship between customer environmental performance and supplier green innovation. The results show that customer environmental performance has a significant positive effect on supplier green innovation. Mechanism analysis reveals that customer environmental performance promotes supplier green innovation through four pathways: supply chain transmission, market investment expectations, institutional policies, and financial constraints. The impact of customer environmental performance on supplier green innovation is more pronounced when the customer enterprise is state-owned, the supplier enterprise is state-owned, or the supplier enterprise holds ISO14001 certification. This study contributes to the literature on supply chain sustainability and provides valuable insights for enterprises on enhancing competitiveness and promoting sustainable supply chain transformation through improved environmental performance.

Climate change and the transition to sustainable development have heightened the global focus on carbon markets and green finance as critical tools for reducing greenhouse gas emissions. Understanding the factors driving carbon market volatility has become increasingly important as countries strive to meet climate goals. In this connection, our study investigates the interplay between green finance and carbon market volatility in China. For this purpose, we use monthly data from January 2015 to April 2023. The findings reveal that policy uncertainty significantly influences carbon market volatility, with a positive short-term relationship indicating that heightened policy uncertainty drives carbon market volatility upward due to increased market volatility. Conversely, issuing green finance-related certificates dampens carbon market volatility, suggesting that enhanced green finance reduces the demand for carbon allowances. This study underscores the critical role of stable economic policies and robust green finance initiatives in mitigating carbon market volatility, providing valuable insights for policymakers aiming to foster resilient and sustainable carbon markets.

Hotel certifications have become increasingly vital in promoting sustainability within the hospitality industry, providing frameworks that guide hotels toward reducing their environmental footprint, enhancing operational efficiency, and gaining a competitive edge in the marketplace. This review explores the development, types, and impact of hotel certifications, with a focus on prominent schemes, such as LEED, Green Key, and EarthCheck. Through an analysis of case studies from globally recognized hotels, we highlight how certifications contribute to significant reductions in energy and water use, improved waste management, and enhanced biodiversity protection, while also delivering economic benefits through cost savings and increased guest loyalty. Our paper also examines consumer perceptions of certifications and their willingness to pay (WTP) for certified hotels. The findings suggest that eco-conscious travelers, particularly younger generations, are willing to pay a premium for hotels that demonstrate a commitment to sustainability; however, consumer awareness of certification schemes remains limited. The barriers to adopting certifications, such as high initial costs, resource limitations, and management resistance, are also discussed, along with the challenges posed by greenwashing and the proliferation of certification schemes. Looking to the future, this review identifies key trends that will shape the evolution of hotel certifications, including increased transparency, the integration of smart technologies, the expanding role of social responsibility, and their alignment with global sustainability goals, such as the United Nations Sustainable Development Goals (SDGs). Hotel certifications are not only crucial for environmental sustainability, but also serve as a powerful tool for enhancing the economic viability of hotels in an increasingly competitive and sustainability-driven market.

While tradable green certificates (TGCs) and carbon emission trading (CET) play key roles in achieving peak carbon and carbon neutrality, the coupling effects between these two policies on the medium- and long-term electricity market and the spot market are still uncertain. In this study, we firstly construct a multi-scale market trading framework to sort out the information transfer of four markets. Secondly, we establish a multi-scale market system dynamics-coupled trading model with five sub-modules, including the medium- and long-term power markets, the spot market, and the carbon market. Subsequently, we adjust the policy parameters (carbon quota benchmark price, carbon quota auction ratio, and renewable energy quota ratio) and set up five policy scenarios to compare and analyze the impacts of the CET and TGC mechanisms on the power market and carbon emission reduction when they act alone or in synergy, in order to provide a theoretical basis for the adjustment of strategies of market entities and the setting of parameters. The results show that CET can increase spot electricity prices and promote renewable energy to enter the spot market, while TGCs can promote a high proportion of renewable energy consumption but lower spot electricity prices for a long time. The coordinated implementation of the CET and TGC mechanisms can improve the power market’s adaptability to high renewable energy penetration, but it may also result in policy redundancy.

Against the backdrop of global efforts towards carbon peak and carbon neutrality, enhancing the level of green innovation in enterprises represents a significant challenge faced by governments worldwide. The practice of establishing a certification system for high-tech enterprises and leveraging this certification to influence corporate behavior has been shown to be an effective approach. This paper constructs an analytical framework based on incentive effects, signaling effects, and external pressure, employing the negative binomial regression method to evaluate the impact of high-tech enterprise certification on green innovation using data from listed companies in China from 2006 to 2023. The research findings indicate that, generally speaking, this certification primarily promotes green innovation through increased government subsidies, alleviation of financing constraints, and enhanced market attention. Further analysis reveals that its impact is particularly pronounced on state-owned enterprises, enterprises in central regions, and labor-intensive enterprises. Based on these research outcomes, this paper recommends that the government should further strengthen the construction of the certification system to enhance its credibility and authority; place greater emphasis on green-oriented fiscal subsidy policies; promote the development of green finance to alleviate financing constraints for enterprises; and refine the external supervision mechanisms of the capital market to provide robust support for enterprise green innovation. This study deepens the understanding of the relationship between government institutional construction and green innovation and provides empirical evidence for transforming the economic development model.

Additionally, the study explores the integration of stochastic modeling and machine learning techniques to address market uncertainties. These results provide theoretical support for policymakers in designing efficient green electricity market regulations and offer strategic insights for PGEs aligning with carbon neutrality objectives. This work bridges theoretical modeling and practical application, contributing to the advancement of sustainable energy policies and the development of green electricity markets. Full article

Advancing new productive forces in agriculture requires the adoption of disruptive green technological innovation by agricultural enterprises. This study analyzes the generative mechanisms for promoting disruptive green technological innovation based on the DSR model and examines the moderating role of green governance alliances. A total of 302 questionnaires were collected from agricultural enterprises in Guangxi, and structural equation modeling was employed for verification. The results indicate that both low-carbon transformation capability and carbon label credibility have a significantly positive impact on disruptive green technological innovation and organizational green learning, with organizational green learning playing a mediating role. Green governance alliances positively moderate the relationship between low-carbon transformation capability, carbon label credibility, and organizational green learning but do not moderate the relationship between low-carbon transformation capability, carbon label credibility, and disruptive green technological innovation. Agricultural enterprises can advance new productive forces and achieve high-quality agricultural economic development by enhancing their low-carbon transformation capability, co-constructing carbon label credibility, and engaging in disruptive green technological innovation. Agricultural enterprises should adopt disruptive green technological innovation, establish carbon certification systems, participate in green learning platforms, and strengthen green governance alliances to promote low-carbon development and enhance market competitiveness.
