At nuclear power plants, risk analysis concerning environmental extremes is crucial. Based on historical data, estimation of return levels is usually performed. For long return periods, a problem is that the related uncertainties of the return levels often get large. Moreover, models need to take into account possible effects of climate change. In this paper, extreme sea levels close to Swedish nuclear power plants are considered. Non-stationary statistical models and the related results of conditional prediction during a typical time horizon of an infrastructure are studied. The influences of parameters in extreme-value distributions and the lengths of observation records are discussed. The effect of land uplift in parts of the Baltic Sea is seen.

The purpose of this study is to provide new evidence on the relationship between trade openness and carbon dioxide (CO2) emissions in Africa. Based on recent data and an uncommon and more informative composite indicator of trade openness proposed by Squalli and Wilson (2011) , we use an augmented Stochastic Impact by Regression on Population, A uence and Technology (STIRPAT) model. Empirical evidence using the Two Stage Least Square estimation (2SLS) validates the "pollution haven" hypothesis and shows that trade openness increases CO2 emissions in Africa. However, the elasticity varies greatly depending on the different measures of trade openness used. Moreover, we nd that trade openness is associated with an increase in CO2 emissions in North Africa, South Africa and West Africa, but rather has a negative effect on CO2 emissions in East Africa and in Central Africa. Furthermore, the quantile regression approach shows that the effect of trade openness is increasing on the Q10th, Q25th, Q50th, and Q75th quintiles, but decreasing at the Q90th quintile, thus highlighting the "scale effect". The results obtained are robust even when using other indicators of environmental quality.

Moving Micro, Small and Medium Enterprises (MSMEs), in developing countries, from linear “take—make—dispose” production patterns to circular models where inputs and natural resources consumption is minimized, and products and waste reuse is promoted, is still a challenge. Environmental transition initiatives with multiple gaps, based on narrow and corrective approaches, isolated measures, and costly and complex technologies suitable for large companies, limit the incursion of MSMEs into the new circularity. It is in this context that the research aims to understand: How to accelerate the transition of MSMEs in developing countries towards circular production models? A critical literature review guided the design, development and analysis of the case study; a small coffee and pig farm located in Colombia, where a circular transition process was undertaken, acted as the unit of analysis. Interviews, theoretical and practical workshops, on-site measurements, systematic observations, and multi-stakeholder dialogs helped to collect and triangulate the empirical data provided by the case. By following systems thinking and sustainable and circular production principles, low-cost, simple and complementary clean technologies were implemented in the farm-system, resulting in multiple benefits at environmental, social and economic levels. This applied research helped to transform a small rural polluting enterprise into a greener and circular business. The study provides theoretical and empirical contributions to the field of research on the transfer of cleaner production and circular economy to MSMEs, expanding our knowledge on the subject.Graphical abstract

The scope for environmental management accounting (EMA) has perpetually received attention in recent years, and it has become a pillar of sustainability in addressing environmental and service delivery challenges. Most scholars focused on EMA in a corporate context, limited attention has been given to local governments in available scholarly articles except for various initiatives by the United Nations to guide local governments in adopting and implementing sustainable environmental management practices. This has continued to affect the uptake of EMA in local governments, particularly in developing economies, as the question concerning the role of EMA practices (EMAPs) in environmental and service delivery remains unexplored. A systematic literature review (SLR) through the use of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to identify EMAPs and their role in promoting environmental and service delivery performance (SDP) in local governments was employed. Articles from Google Scholar and Scopus published between 2000 and 2023 were considered. The researchers identified and evaluated energy accounting, material flow accounting, water management accounting, carbon management accounting and biodiversity management accounting as effective EMAPs to address local governments’ environmental and service delivery challenges. Furthermore, a conceptual framework to integrate EMAPs with environmental improvement and service delivery plans was developed and has implications for policymakers, communities, government and environmental specialists. The lessons learned from the research are pertinent to developing sustainable cities in emerging economies and further expose the need for further research to consider accounting approaches from higher-income countries as benchmarks for future development of ecosystem accounting to assist local governments in managing environmental challenges.

Today, the concept of the circular economy (CE) has different meanings for various scholars. There are numerous definitions that focus on highlighting different aspects and principles of CE. However, there has been little effort made regarding the focus of CE definitions on various environmental aspects, such as waste management, wastewater treatment, biodiversity, carbon emissions and climate change. To clarify this complex environment, this paper examines the research endeavors surrounding the CE by analyzing 136 descriptions sourced from various entities and researchers. In particular, a more thorough investigation of CE is warranted to explore the possible ways of adopting its principles. To achieve this, Microsoft Excel and Leximancer™ software are employed to thematically and content-wise analyze the descriptions. The results reveal that "waste" and "recycling" are central concepts in CE descriptions, which align with the goals set forth in Union legislative acts, the "Roadmap for a Resource-Efficient Europe," and the European Green Deal aimed at increasing recycling rates and eliminating waste.

During the last decades, natural hazards, such as earthquakes, volcanic eruptions, landslides, floods, storms, droughts, and cyclones, have increased in frequency and severity, influenced by climate change and population growth. These natural hazards can become sudden-onset disasters, causing human losses and property damages that affect economic stability and growth. Although there is a pressing need for risk decrease and adaptation strategies to these unexpected events, targeted natural hazard insurance would be a valuable tool to counteract governmental and individual consequences. This paper summarizes an overview of risk assessment and mitigation strategies based on geological, geomorphological, and meteorological factors. The study includes an examination of monitoring systems for movement and gas emissions, risk and emergency maps, and highlighting the vulnerability of different areas at national and regional levels. Furthermore, the paper addresses the importance of promoting comprehensive geological and geotechnical knowledge among citizens of every socio-economical group and proposing the tools to effectively deliver the message, aiming at increasing the willingness for natural hazard insurance at both individual and governmental scales for human and property protection.
