Addressing the urgent challenge of climate change is a paramount global concern, with European economies showcasing commitment through the ambitious European Green Deal, COP, and sustainable development goals. However, the region's reliance on fossil fuels raises questions about the initiatives affecting the environmental neutrality goals in Europe. To find an answer to this, the present study investigates the impact of energy intensity and environmental tax revenues on environmental management efforts in terms of air, water, and waste pollution abatement in Europe by utilizing data spanning 1994 to 2020 for major European economies that held over 95 % of European economic output. The sample is grouped into two panels based on economic growth level. The study employs advanced econometric techniques to perform the preliminary checks, and GMM-PVR is used as the main study model. Aggregate panel findings reveal significant associations between energy intensity, environmental tax revenues, and environmental management. Notably, higher energy intensity is positively linked to increased environmental management activities, reflecting a commitment to address abatement goals and indicating funds are allocated toward pollution mitigation, aligning with Europe's emphasis on sustainability. Foreign direct investment has a negative relationship with environmental management. However, in Panel A, environmental tax revenues, economic growth, and trade openness reveal a negative impact on environmental management, suggesting that intense economic activities surpass the environmental tax revenue efforts to abate pollution, unlike Panel B, which is effective in pollution reduction. The study's policy implications stress enhancing the energy efficiency of economic giants while simultaneously strengthening mechanisms for utilizing environmental tax revenues and reinforcing environmental regulations to align foreign direct investment with sustainable practices. International collaboration is essential to ensure trade relations align with environmental goals, contributing to global efforts to combat climate change.

Recent progress in microgrids (MGs) has resulted in increased acceptance and utilization of green energy sources, energy storage technologies, and MGs. This has facilitated a more effective and practical administration of distributed energy resources (DERs). The progress in MGs, along with the implementation of hierarchical supervision and monitoring, has facilitated the transmission of information within contemporary communication systems. The incorporation of cyber physical systems (CPS) within MGs has heightened their susceptibility to cyber-attacks, thereby converting them into cyber–physical systems. Thus, emphasizing the importance of preventing, detecting, and isolating cyber-attacks is essential for the effective management of MG. This study offers an in-depth examination of cyber security within the energy sector, exploring the historical backdrop of cyber-attacks and classifying different forms of MG breaches, encompassing both cyber and physical security strategies. This study explore into the intricate communication networking infrastructure susceptible to attacks, particularly emphasizing data centers, and underscores the critical role of MG management in alleviating cyber risks. The study presents a framework that strategically improves cyber security defenses through a classification of countermeasures. The work offers significant perspectives on present and forthcoming advancements, promoting a forward-thinking strategy for safeguarding essential infrastructure in a world that is becoming more digitized.

As the Chinese government places increasing emphasis on the establishment of mechanisms for carbon emission reduction and inter-provincial collaboration, transparency governance offers a novel solution to the traditional challenges of territorial governance in this context. This paper innovatively constructs a Provincial Transparency Index (PTI) for China and examines the effect of transparency on provincial carbon emission reduction using panel data models and spatial Durbin models. Furthermore, a hierarchical regression analysis is conducted to test the mechanisms. The results reveal that the PTI has a significant impact coefficient of 0.481 on carbon emissions, while the quadratic coefficient is −0.693, indicating that PTI has an inverted "U" - shaped effect on local carbon emissions, with significant spatial spillover effects that diminish marginally. Transparency governance primarily promotes inter-provincial coordinated carbon reduction by reducing collaboration costs through marketization and increasing breach costs through institutional guarantees. Therefore, China should accelerate the establishment and improvement of transparency governance mechanisms for collaborative carbon reduction among provinces, and enhance the disclosure and supervision of carbon reduction information at the provincial level.

Aligned with the war in Ukraine, Russia has significantly withheld natural gas exports to Europe since 2021. As there are no EU-wide sanctions on imports of Russian natural gas, the Ukraine transit as well as imports via Turkey and LNG have remained active during 2022–24. However, the Russian-Ukrainian transit agreement expires at the end of 2024 and discussions about new sanctions on natural gas as well as the threat of further supply disruptions continue to pose uncertainty for European markets. We use the Global Gas Model (GGM) to investigate the necessity of Russian gas exports for European gas consumption. Our results of different scenarios indicate that the EU’s gas consumption can be largely satisfied in all demand and Russian supply scenarios. This result holds also for a complete disruption of Russian exports to the EU thanks to diversification and some demand side response.

This study examines the influence of institutional performance, green finance, and technology on environmental performance in mineral-based nations involved in the Belt and Road Initiative (BRI), focusing on the period of economic growth from 1991 to 2019. The use of the STIRPAT model, along with spatial econometric methods, yields noteworthy results in the analysis. The adoption of renewable energy leads to a 12 % decrease in CO₂ emissions among the countries studied, underscoring its crucial importance for environmental sustainability. Enhancements in institutional quality indicate a 14 % increase in ecological efficiency, whereas a rise in government spending on renewable energy is associated with a 10 % boost in the utilization of green finance and promoting environmental conservation. Nonetheless, financial development shows a varied impact, highlighting the need for policy measures to align growth with sustainability. The findings highlight the essential importance of customized policies and strong institutional structures when tackling environmental issues. This study not only addresses a gap in understanding the interplay of these variables but also provides practical insights for policymakers to promote sustainable development. The results hold considerable importance for reaching sustainable environmental goals and improving cooperation among BRI countries.

To study the behavioral strategies of government agencies and the coal power industry chain under environmental regulation, an evolutionary game model has been constructed. Furthermore, a reinforcement learning model has been developed using the payoff matrix. By analyzing the characteristics of different environmental regulatory policies and the future development trends of China's coal power industry chain, we evaluate the impact of various regulatory policies on the game players from both strategy and return perspectives. The results show that (1) Power companies are policy sensitive; (2) In the context of both market-based and voluntary environmental regulation policies, there exists a potential to trigger the " coal-power paradox ". (3) Market-based environmental regulation is most effective, whereas command-based environmental regulation offers prompt policy feedback, and voluntary environmental regulation merely serve as a supplementary regulatory tool.

The current climate targets of most countries are insufficient to limit global warming to 1.5 °C. This work emphasises how the gap between recent governmental policies for the energy transition and scientific findings may be jeopardising the fulfilment of the Paris Agreement. Concretely, Chile is used to identify the most significant global issues behind this gap and underline the importance of weighing in more insights from science. The analysis showed that the gap is mainly based on three critical problems in modelling tools for simulating long-term energy scenarios: (1) low temporal resolution in the modelling; (2) overly pessimistic and even outdated cost projection assumptions for key technologies, especially for solar photovoltaics; and, (3) key enabling technologies and infrastructures are not fully represented, such as decentralised solutions, Power-to-X for e-fuel production, and sector coupling. The study finalises by providing recommendations for energy decision-makers, such as policymakers, planners, and investors, to help speed up the needed energy transition that simultaneously tackles environmental, public health, and socioeconomic challenges.

大多数国家目前的气候目标不足以将全球升温控制在 1.5 °C。这项工作强调了近期政府能源转型政策与科学发现之间的差距如何可能危及《巴黎协定》的实现。具体而言，智利被用来确定这一差距背后最重要的全球性问题，并强调从科学中获得更多见解的重要性。分析表明，差距主要基于模拟长期能源情景的建模工具中存在的三个关键问题：(1) 建模的时间分辨率低；(2) 对关键技术，特别是太阳能光伏技术的成本预测假设过于悲观，甚至过时；(3) 未充分体现关键的使能技术和基础设施，如分散式解决方案、用于生产电子燃料的 "Power-to-X "技术以及部门耦合。研究最后为能源决策者（如政策制定者、规划者和投资者）提供了建议，以帮助加快所需的能源转型，同时应对环境、公共健康和社会经济挑战。

The unmanageable problem of climate change and the energy crisis caused by the war in Ukraine show the importance of promoting the consumption and production of renewable energy. Therefore, the aim of this study was to analyse the main determinants of selecting a green electricity supplier by using the Modified Theory of Planned Behaviour in light of concerns about the war in Ukraine. According to the data of a representative survey conducted in 2022 in Lithuania, 39 % of all respondents chose green electricity. When analysing the determinants that led individuals to choose this electricity supplier, attitudes and subjective norms had a direct and significant influence on this behaviour. Meanwhile, climate change concerns and attitudes indirectly led people to select a green electricity supplier. Considering the war in Ukraine, only governmental aspects and concern about the war were positively associated with such behaviour. Of the socio-demographic factors, only the level of education had a significant but negative influence on this behaviour. Age, gender and income level had no significant effect on the selection of green electricity suppliers. Thus, policymakers should focus on environmental education to better select green electricity suppliers.

Reducing greenhouse gas emissions in the transport sector is among the hardest challenges in transforming energy systems to zero emissions. Transport energy demands are driven by an interplay of social behavioral, technical factors, political decisions and economic conditions, motivating detailed transport demand modeling.

In Germany, transport energy supply – increasingly from electricity – is expected to challenge the energy supply infrastructure. Recent studies assume large shares of imported clean energy carriers and proclaim global renewable fuel import potentials. Simultaneously, sustainable biofuels’ impacts on required electricity supply infrastructure is yet not well understood.

We assess the impact of climate ambition, indirect electrification shares and biofuel availability on energy supply infrastructure in 8 demand scenarios. Coupling the European energy system model REMix with the biofuel allocation model BENOPTex, we calculate cost-minimal energy supply infrastructure for each scenario. This high detail of integrated transport sector and biofuel modeling is novel to energy system analysis.

We find that incorporating user preferences in sales decisions clearly narrows the range of transport energy demand. As the German renewable energy potential is exhausted, higher clean fuel demand is covered by imports. Still, the use of these fuels drives the required power grid expansion, and especially electrolysis and fuel production capacities. Biofuel availability may significantly reduce e-fuel demand reducing cost-optimal hydrogen production capacity in the medium term and necessary grid expansion within Germany beyond 2030.

The model outcome is limited by assumptions on costs and availability of import options. Future work should further address modal shift transport scenarios.

The role of energy efficiency is frequently portrayed as the most prominent tool for achieving carbon neutrality and sustainable development goals. Thus, the present study is intended to explore the dynamic role of energy efficiency, green energy, green technology, and environmental policy stringency for achieving carbon neutrality goals in the presence of other variables, such as economic growth. A series of advanced econometric techniques, including a cross-sectional dependence test, a second generation unit, a joint correlated effect-mean group (CCE-MG), and an augmented mean group (AMG), were adopted to assess the panel data from 1990 to 2020 empirically. The initial finding indicates the existence of cross-sectional dependence, data stationarity, slope heterogeneity, and panel co-integration among the variables. Lastly, based on the nature of the panel data as cross-section dependence in the data, CS-ARDL was preferred over traditional econometric techniques. Additionally, the CS-ARDL more efficiently tackles the unobserved elements and heterogeneity across the cross sections. Findings exhibited that energy efficiency, green energy, and environmental policy stringency are promising factors for addressing the growing carbon emission problems. Moreover, we also applied non-linear ARDL, and the finding revealed that a one percent positive change in energy efficiency, EPS, and GDP would have a negative impact on carbon emission, and vice versa. Additionally, the Dumitrescu-Hurlin causality test revealed a causal relationship between environmental policy stringency, energy efficiency, green technology, and green energy consumption in the BRICS countries. Based on the current study's findings, diverse and feasible policy options are recommended for attaining carbon neutrality goals.
