Environmental regulations in developing countries and the span of firms' production stages: Evidence from China

AbstractDespite the well‐established tradeoff between economic development and environmental protection, research on the economic costs of alleviating pollution, especially from the perspective of global value chain upgradation, is scarce. In 2006, in its Eleventh Five‐Year Plan, the Chinese government implemented strict environmental regulations against air pollution. We examine the causal effect of these environmental regulations – which were stricter for higher pollution emission provinces compared with lower pollution emission provinces – on Chinese firms' span of production stages after the policy shock. A difference‐in‐difference‐in‐differences estimation reveals that, first, environmental regulations have a significantly negative effect on firms' span of production stages that robustness checks corroborate; second, the negative effects of environmental regulations on firms' span of production stages are realised through the simultaneous decline in import upstreamness and increase in export upstreamness. Heterogeneity tests indicate that the effects are more significant for firms in eastern China, and foreign‐owned firms; finally, the negative effects are manifested through the emission‐related input and output, productivity, and innovation mechanisms. Meanwhile, there are significant emission reduction effects. These results have implications on environmental policies in developing countries in terms of reiterating the need to achieve the dual objectives of environmental protection and global value chain upgradation.

Spatiotemporal comprehensive evaluation of water quality based on enhanced variable fuzzy set theory: A case study of a landfill in karst area

Water quality assessment is a crucial step in water resource management and pollution prevention, and is essential for achieving sustainable development. Current methods for evaluating water quality often fall short of meeting the needs of water resource management due to the lacks of accuracy and applicability. In this paper, an enhanced water quality evaluation system was established by Principal Component Analysis / Factor Analysis (PCA/FA), Analytic Hierarchy Process / Entropy Weight Method / Game Theory (AHP/EWM/GT) and Variable Fuzzy Set Theory (VFST). The accuracy of this method was verified by evaluating the water quality of a landfill in a karst area and comparing with the conventional evaluation models. The results indicated that the highest influence on groundwater quality in the study area came from human factor, dissolved solid factor, biological factor, and nutritional factor. The quality of surface water and groundwater in the study area was primarily Grade Ⅱ, accounting for 62.5% and 75%, respectively. The predominant groundwater type was HCO3-Ca·Mg, which was strongly affected by karstification. The NH3-N and TP in the surface water had the highest variability, and the variation coefficients of K+, Na+, Ca2+, Cl−, NH3-N, NO3−, TDS, and TH in the groundwater were greater than 1. The surface water quality gradually improved between 2018 and 2019. Overall, the groundwater quality in the southern and central regions was inferior to that in the northern and surrounding areas. There could be a hydraulic link between the surface water and landfill in the research location, while karstification and leachate primarily impacted the groundwater. The water quality evaluation method established in this study can make a significant contribution to water resource management, which has important practical significance for environmental protection and indirect social value to the public.

Room temperature gas sensors for NH3 detection based on SnO2 films and lamellar-structured Ti3C2Tx MXene heterojunction nanocomposites

Efficient and accurate detection of ammonia (NH3) by gas sensors at room temperature holds great practical value and significance in industrial production and environmental protection. In this work, we designed SnO2/Ti3C2Tx heterojunction nanocomposites via a facile RF magnetron sputtering technique. Benefitting from the surface porosity and few lamellar-structured of the composites, as well as the construction of heterojunctions between SnO2 and Ti3C2Tx, the SnO2/Ti3C2Tx sensor demonstrated a response of up to 13.35 % towards 50 ppm NH3 at room temperature, which was 3.5 times higher than the Ti3C2Tx-based sensor. Meanwhile, the response/recovery time was reduced to 24.9/86.5 s. In addition, the SnO2/Ti3C2Tx sensor exhibited good selectivity, repeatability, and long-term stability. This work should provide an effective strategy for the design of high-performance NH3 gas sensors at room temperature.

Marine thraustochytrid: exploration from taxonomic challenges to biotechnological applications

Thraustochytrids, as a distinct group of heterotrophic protists, have garnered considerable attention owing to their remarkable adaptability in extreme marine environments, pronounced capacity for metabolic regulation and prolific production of high-value metabolites. The taxonomic classification of these microorganisms presents a substantial challenge due to the variability in morphological characteristics under different culture conditions. And this undermines the efficacy of traditional classification systems on physiological and biochemical traits. The establishment of a polyphasic taxonomic system integrating genomic characteristics in the future will provide new avenues for more accurate classification and identification. Thraustochytrids can effectively accumulate bioactive substances such as docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), squalene and carotenoids. Through fermentation optimization and genetic modification, scientists have significantly enhanced the production of these metabolites. Moreover, the application of thraustochytrids in aquaculture, poultry and livestock feed has significantly improved animal growth and physiological indicators meanwhile increasing their DHA content. Natural bioactive substances in thraustochytrids, such as terpenoid compounds with antioxidant properties, have been proposed for application in the cosmetics industry. In the field of pharmacology, thraustochytrids have shown certain anti-inflammatory and anti-cancer activities and provide potential for the development of new oral vaccines. Additionally, they can degrade various industrial and agricultural wastes for growth and fatty acid production, demonstrating their potential in environmental bioremediation. Therefore, thraustochytrids not only exhibit tremendous application potential in the field of biotechnology, but also hold significant value in environmental protection and commercialization.

Ecological Literary Heritage: Lessons from Classics for the Environmental Movement

This paper explores the enlightenment significance of classic ecological literature works to the environmental protection movement. Through literature research and case analysis, three representative ecological literary works, “Silent Spring,” “Dune,” and “Call of the Wild,” were selected for in-depth analysis. The study found that these classic works express profound environmental protection values, reflect environmental problems such as chemical pollution, resource depletion, and wildlife protection, and reflect care for the ecosystem. Among them, “Silent Spring” reveals the harm of pesticides to the biological chain, “Dune” explores the relationship between resource exploitation and ecological protection, and “Call of the Wild” depicts the harmonious coexistence between man and nature. The environmental awareness shown in these works has important enlightenment for the contemporary environmental movement, arousing the public’s environmental awareness and providing reference for environmental protection actions and strategy formulation. The study believes that ecological literature contains rich environmental protection value, is the source of ideas for the environmental protection movement, and has a lasting impact on promoting the environmental protection process.

Rewilding the Detroit, Michigan, USA–Windsor, Ontario, Canada Metropolitan Area

Rewilding attempts to increase biodiversity and restore natural ecosystem processes by reducing human influence. Today, there is growing interest in rewilding urban areas. Rewilding of the Detroit, Michigan, USA and Windsor, Ontario, Canada metropolitan area, and its shared natural resource called the Detroit River, has been delineated through the reintroduction of peregrine falcons and osprey, and a return of other sentinel species like bald eagles, lake sturgeon, lake whitefish, walleye, beaver, and river otter. Rewilding has helped showcase the value and benefits of environmental protection and restoration, ecosystem services, habitat rehabilitation and enhancement, and conservation, including social and economic benefits. Improved ecosystem health and rewilding have become a catalyst for re-establishing a reconnection between urban denizens and natural resources through greenways and water trails. The provision of compelling outdoor experiences in nature, in turn, can help foster a personal attachment to the particular place people call home that can help inspire a stewardship ethic.

Synergistic Effect of Sodium Cyanoborohydride in Pb‐Sn Perovskite Solar Cells

AbstractPb‐Sn mixed perovskite has received extensive attention because of its high research value in environmental protection and theoretical prospects. However, the film defects brought on by the quick crystallization of Pb‐Sn mixed perovskites and the facile oxidation of Sn2+ to Sn4+ are detrimental to the performance of Pb‐Sn perovskite solar cells (PSCs). Here, aiming at the interface of Pb‐Sn PSCs, which has been less studied, a reducing agent is first introduced on the top of Pb‐Sn mixed perovskite interface. The results show that in NaBH3CN(SC), B─H can suppress the oxidation of Sn2+ and C≡N can enhance the perovskite crystallinity and passivate the surface defects. Benefitting from this synergistic effect, a champion power conversion efficiency of 21.3% is obtained for Pb‐Sn PSCs. In addition, the encapsulated device can maintain good stability under maximum power point tracking conditions.

The surface structure of nanosilica produced from sodium silicate by the carbonation process

CO2 was used to prepare nanosilica particles through a carbonization reaction in a Na2SiO3 solution, aiming to convert CO2 into value-added products. The relationship between the specific structure of the as-prepared nanosilica and the sodium silicate concentration, reaction temperature, reaction time, and aging time was explored by TEM, BET, and XRD analysis. The growth process of nanosilica particles was relatively slow with the increase in the Na2SiO3 concentration, which resulted in the formation of large primary particles, reducing the specific surface area. The decreasing temperature reduced the polymerization of Si(OH)4 and SiOSi(OH)3, reducing the specific surface area. Meanwhile, the effects of reaction time and aging time on the surface structure of silica nanoparticles were studied. Different surface structure of nanosilica particles were synthesized by controlling the carbonization process conditions, which expand the application of nanosilica products. At present, the research on the carbonization preparation of nanosilica mainly focused on the carbonization process conditions and modification technology, but the research of control mechanism of nanosilica surface structure and properties was insufficient. This study focused on the relationship between surface structure evolution and properties, and provided a theoretical basis for the mechanism of the influence factors of preparation process on the structure evolution of prepared nanosilica. And the process reduced CO2 emission, which had important environmental protection value.

SANCTIONING REQUESTS OF PUBLIC ADMINISTRATION ENTITIES

The sanctioning of requests by public administration authorities in administrative proceedings is the least analysed, debated and completely unstructured institute of administrative law. The sanctioning of actions of public administration entities is closely related to the administrative supervision of the activities of economic operators, which helps to ensure the harmonisation of the individual economic operators and economic sectors, as well as of public health, environmental protection, and other constitutional values. Administrative supervision and other control by public administration is defined in the academic literature as a public administration activity in which a public administration entity monitors the compliance of the behaviour of its subordinates with legal norms, and, in the event of non-compliance, responds with the measures for the correction or punishment of behaviour. Despite the importance of administrative supervision and the impact it has on economic operators, we do not find any mention of sanctioning requests from public administration authorities in either the Law on Administrative Proceedings or the Law on Public Administration. The article presents the variety of requests for sanction submitted by public administration entities to the administrative court, possible classifications of applications submitted to the court and peculiarities of individual types of requests. The article also presents an analysis of the statistical data on the last few years of the examination of applications for sanctioning of public administration authorities before the Vilnius Regional Administrative Court, which has exclusive competence for the examination of these applications, the diversity of this type of applications (administrative cases), the main procedural peculiarities and problems of the examination of administrative cases of this type in the court, and provides insights and recommendations.

Selective leaching process for efficient and rapid recycling of spent lithium iron phosphate batteries.

With the continuous development of new energy vehicles, the number of decommissioned lithium iron phosphate (LiFePO4) batteries has been constantly increasing. Therefore, it is necessary to recover metal from spent LiFePO4 batteries due to the high potential for environmental protection and high resource value. In this study, sodium persulfate (Na2S2O8) was selected as the oxidant to regulate and control the oxidation state and proton activity of the leaching solution through its high oxidizing ability. Selective recovery of lithium from LiFePO4 batteries was achieved by oxidizing LiFePO4 to iron phosphate (FePO4) during the leaching process. This paper reports an extensive investigation of the effects of various factors, including the acid concentration, initial volume fraction of the oxidant, reaction temperature, solid-liquid ratio, and reaction time, on lithium leaching. Li+ reached a high leaching rate of 93.3% within 5 minutes even at a low concentration of sulphuric acid (H2SO4), and high-purity lithium carbonate (Li2CO3) was obtained through impurity removal and precipitation reactions. In addition, the leaching mechanism was analysed by both X-ray diffraction and X-ray photoelectron spectroscopy characterization. The results show that the obtained high lithium-ion (Li+) leaching efficiency and fast Li+ leaching time can be ascribed to the superior oxidizing properties of Na2S2O8 and the stability of the crystal structure of LiFePO4 during the oxidative leaching process. The adopted method has significant advantages in terms of safety, efficiency and environmental protection, which are conducive to the sustainable development of lithium batteries.

Siblings, shopping, and sustainability: Birth-order differences in green consumption.

Several studies have examined the role of birth order in shaping human personality, but fewer have tested this variable in relation to other pressing issues. We conducted a birth-order study on green consumption, which enabled us to detect a small-to-moderate effect size equivalent to r = 0.15 or d = 0.30 with sufficient statistical power (N = 335). To capture green consumption, participants indicated their tendency to express the value of environmental protection through purchases and consumption behaviors. Firstborns (vs. laterborns) consistently expressed lower concerns linked to environmental protection in their purchase patterns. While the effect size of this finding was small-to-moderate by conventional standards and in direct contrast to the findings from a recent article on the same topic, these results could still be informative to address challenges associated with climate change considering the number of individuals with siblings in the world and the ease with which birth-order data can be collected.

Developing an Urban Computing Framework for Smart and Sustainable Neighborhoods: A Case Study of Alkhaledia in Jizan City, Saudi Arabia

Urban computing is the incorporation of computing, sensors, and actuation technology into urban life. In Saudi Arabia, the neighborhoods lack an integrated approach to social, economic, and environmental values, thereby creating consequences, such as inefficient mobility, poor environmental protection, low quality of life, and inadequate services or facilities. This article aims to develop a smart sustainable neighborhood framework (SSNF) to create districts that contribute to a healthy environment, sustain a strong community, and thrive in economic value. The framework is created by two main factors, first is identifying and analyzing the categories of urban computing. Second is choosing the appropriate indicators from sets of standards, including sustainable development goal (SDG) 11, as developed by the United Nations. These two factors shaped the proposed “smart and sustainable urban computing framework (SSUCF)” of “people”, “prosperity”, and “environment” dimensions, and it has been applied to the Alkhaledia district as a case study. The result indicates that urban computing can be used as the basis of support, along with smart and sustainable standards to produce an SSNF. Furthermore, with the analysis of relevant data, this framework can be used in similar neighborhoods to enhance the quality of residents’ lives, environmental protection, and economic values.

Therefore, it is very necessary to apply big data technology to environmental protection work. Through the analysis of the application characteristics of big data technology, it can be seen that big data technology has made environmental protection work data-driven, and also further embodied the fundamental value of environmental protection. This article analyzed the changes in the environment by establishing environmental protection measures and applying big data, and calculated whether there was a significant improvement in the environment supported by big data technology. This article calculated the dust reduction data after the intervention of big data environmental protection measures in 2022 through experiments, which was significantly lower than the dust reduction data in 2019. Therefore, it has great advantages in environmental detection and other aspects.

Preliminary Analysis of Voluntary Information on Organic Milk Labels in Four European Union Countries

The concern for the environment among European consumers is growing and in the future the need for sustainable shopping is expected to increase. Through transparent on-packaging communication with consumers, organic producers have the opportunity to show attributes of organic production system and build a strong market position. The aim of the study was to analyse voluntary packaging information on organic milk from four European markets in the context of organic food quality, i.e., Germany, the Netherlands, Italy and Poland. More specifically, the textual content of 106 organic milk packages was analysed and voluntary information on each package was categorized according to process- and product-related organic milk attributes. The assortment and content of voluntary packaging information varied across the four countries. The largest number of products was found on the German market (37) and the smallest on the Polish market (14). Dutch milk had the greatest amount of voluntary information on animal welfare, product locality, environmental protection, quality confirmation, naturalness and nutritional value. German milk had the most information on enjoyment and conditions of processing, while the Italian milk on the social perspective. The products available on the Polish market had the least voluntary information. Pasteurized organic milk had noticeably more information about organic quality attributes than micro filtrated and UHT milk.

Consumer attitudes and sociodemographic profiles in purchasing organic food products: evidence from a Greek and Swedish survey

PurposeThis study explores Greek and Swedish consumers' attitude towards organic food consumption in order to demonstrate possible differences that can be identified based on health and ecological consciousness beliefs rather than demographic factors. The examination of an emerging and a more mature market allow the authors to provide more targeted marketing strategies that possibly increase organic food consumption in both countries.Design/methodology/approachThe authors adopt an econometric approach to the analysis of consumer behavior in relation to organic food consumption in Sweden and Greece. More specifically, the authors examine the motivations and postexperiences of organic food consumers of different socioeconomic profiles in these two countries, one in northern and one in southern Europe. The authors apply an ordered logistic regression analysis model to map out the interaction between consumer attitudes and sociodemographic variables.FindingsThe authors results show that consumers in Sweden more frequently purchase organic foods than consumers in Greece. Environmental protection and ethical values increase the odds for Swedish organic food consumers to buy organic food products. Health consciousness and family well-being are perceived as factors that increase the odds for Greek organic food consumers to buy organic foods. Sociodemographic factors do not play a pivotal role for consumer behavior in relation to organic food in both countries.Originality/valueThis study distinguishes between organic food consumers in two countries with different levels of organic food production and export activity, size of organic market, national organic labeling system and legal definition and standards of organic food. Within these differences, the organic food industry could align its marketing efforts better rather focus on simplistic demographics. The current view unfolds the fact that there are limited studies comparing two European markets at different stages of development and the factors that influence organic food consumer behavior.
