ABSTRACT
In December 2019, a novel coronavirus broke out in Wuhan City, Hubei Province, and, as the center of the coronavirus disease 2019 (COVID-19) epidemic, the economy and production throughout Hubei Province suffered huge temporary impacts. Based on the input–output and industrial pollution emissions data of 33 industrial industries in Hubei from 2010 to 2019, this article uses the non-parametric frontier analysis method to calculate the potential production losses and compliance costs caused by environmental regulations in Hubei's industrial sector by year and industry. Research has found that the environmental technology efficiency of the industrial sector in Hubei is showing a trend of increasing year-on-year, but the overall efficiency level is still not high, and there is great room for improvement. The calculation results with and without environmental regulatory constraints indicate that, generally, production losses and compliance costs may be encountered in the industrial sector in Hubei, and there are significant differences by industry. The potential production losses and compliance costs in pollution-intensive industries are higher than those in clean production industries. On this basis, we propose relevant policy recommendations to improve the technological efficiency of Hubei's industrial environment, in order to promote the high-quality development of Hubei's industry in the post-epidemic era.
ABSTRACT
The transportation industry is characterized as a capital-intensive industry that plays a crucial role in economic and social development, and the rapid expansion of this industry has led to serious environmental problems, which makes the eco-efficiency analysis of the transportation industry an important issue. Previous research paid little attention to the regulatory scenarios and suffered from the incomparability problem, hence this paper aims to reasonably estimate the eco-efficiency and identify its evolutionary characteristics. We measure the eco-efficiency and the corresponding global Malmquist–Luenberger productivity index using a modified model of the data envelopment analysis framework, in which different regulatory constraints are incorporated. Based on the empirical study on the transportation industry of thirty provinces in China, we find that the eco-efficiency of Chinese transportation industry experienced a slight increase during 2015–2016, a sharp decline during 2016–2017, and a continuous rise since year 2017. The Middle Yangtze River area was the best performer among the eight regions in terms of eco-efficiency, while the Southwest area was placed last. The global Malmquist–Luenberger productivity index showed an earlier increase and later decrease trend, which was quite consistent with the reality of the variation of inputs and outputs and the emergence of COVID-19. Moreover, the best practice gap change was found to be the main driven force of productivity. The empirical results verify the practicability of our measurement models and the conclusions can be adopted in guiding the formulation of corresponding policies and regulations.
ABSTRACT
How to accelerate the clean use of fossil energy and promote the transformation and upgrading of energy structure is an important challenge commonly faced by countries around the world. In the post-Covid-19 era, the uncertainties faced by countries around the world are increasing and the frequency of policy adjustments in various countries is accelerating. The discharge of pollution by enterprises is significantly impacted by environmental regulatory policies. Under the carbon neutrality goal, the uncertainty of environmental policy caused by multiple political factors can directly influence the decisions made by businesses and residents, in turn, affect their confidence and expectations. However, researchers have given limited attention to measuring the environmental policy uncertainty index (EPUI). In this paper, we select 460 newspapers from the China National Knowledge Infrastructure (CNKI) newspaper database from 2001 to 2016 and use the text analysis method to directly construct China's national, provincial, and prefecture-level EPUI. The results show that China's EPUI has obvious stage characteristics and regional characteristics. By applying the Chinese city-level EPUI to the field of urban pollution reduction, we have obtained an important finding that when urban environmental policy uncertainty increases by 1%, urban industrial sulfur dioxide emission decreases by about 0.145%, and carbon dioxide emission decreases by about 0.053%. We believe that this is due to an increase in environmental policy uncertainty inhibiting the development and scaling of secondary industries.
ABSTRACT
The paper briefly sketches different "adaptations” possible to address the Covid crisis and then advances three possible avenues for future policy analysis of Covid-related measures, each of these avenues being based on a "conjecture”, respectively an evolutionary, a critical, and a cosmopolitan, and conjecture. The evolutionary conjecture implies regulatory transplants, the critical conjecture elicits competition of Covid-related measures, and the cosmopolitan conjecture assumes coordination of policies. The paper discusses how these conjectures based on pre-Covid literature could explain the regulatory dynamics and then asserts that growing evidence shows that regulatory measures appear to naturally lead to a "polity convergence” based on a common core of "Covid-biopower” and "Covid-biopolitics”. This convergence defies the initial expectations that the fragmented reactions to the Covid crisis could be explained by using the traditional research tools and also poses unprecedented critical issues that demand an expansion of the horizon of policy research.
ABSTRACT
The purpose of this research is to study the changes in the market structure of China's pulp and paper product imports. In particular, the import trade environment and market layout of Chinese pulp and paper products have changed under the international context of the coronavirus pandemic and the Sino-US trade dispute and the domestic policy context of zero imports of Chinese waste paper. This study attempts to fill the gap regarding the influencing factors of market structure, while contributing new ideas on China's trade in pulp and paper products. Based on pulp and paper product import and export trade data from 2005 to 2021, a trade gravity model was used to explore the changes in the share of China's trade partners for pulp and paper product imports and their influencing factors. The results indicated that the outbreak of COVID-19 led to a significant increase in China's imports of packaging paper products, bringing about an increase in Indonesia's status as a partner in China's pulp and paper product trade. The US-China trade dispute had an impact on pulp and paper product trade between the two countries, with China's tax countermeasures causing the US to lose its status as a trading partner in China for pulp and paper product imports. The center of gravity for paper product imports has moved from the US and Japan to Indonesia and Russia. The restrictions on waste paper imports have shifted the focus of China's paper raw material imports, with the US no longer being the main importer of China's paper raw materials. Specifically, the main importers of wood pulp are Brazil and Chile, while the main importers of waste paper pulp are Thailand and Malaysia. In the future, China needs to continuously strengthen dialogue with the United States to resolve trade disputes and create a favorable environment for trade in pulp and paper products. At the same time, China's paper enterprises should strengthen the expansion of the Southeast Asian market and reduce dependence on the US market, and China should continue to improve the waste paper recycling system and improve the utilization rate of domestic waste paper.
ABSTRACT
PurposeCarbon trading mechanism has been adopted to foster the green transformation of the economy on a global scale, but its effectiveness for the power industry remains controversial. Given that energy-related greenhouse gas emissions account for most of all anthropogenic emissions, this paper aims to evaluate the effectiveness of this trading mechanism at the plant level to support relevant decision-making and mechanism design.Design/methodology/approachThis paper constructs a novel spatiotemporal data set by matching satellite-based high-resolution (1 × 1 km) CO2 and PM2.5 emission data with accurate geolocation of power plants. It then applies a difference-in-differences model to analyse the impact of carbon trading mechanism on emission reduction for the power industry in China from 2007 to 2016.FindingsResults suggest that the carbon trading mechanism induces 2.7% of CO2 emission reduction and 6.7% of PM2.5 emission reduction in power plants in pilot areas on average. However, the reduction effect is significant only in coal-fired power plants but not in gas-fired power plants. Besides, the reduction effect is significant for power plants operated with different technologies and is more pronounced for those with outdated production technology, indicating the strong potential for green development of backward power plants. The reduction effect is also more intense for power plants without affiliation relationships than those affiliated with particular manufacturers.Originality/valueThis paper identifies the causal relationship between the carbon trading mechanism and emission reduction in the power industry by providing an innovative methodology for identifying plant-level emissions based on high-resolution satellite data, which has been practically absent in previous studies. It serves as a reference for stakeholders involved in detailed policy formulation and execution, including policymakers, power plant managers and green investors.
ABSTRACT
The impact of anthropogenic greenhouse gas emissions on the increase in the average temperature on the planet and the risk of initiating irreversible processes are recognized by most of the scientific community as real threats to humanity. Many countries have a legal and institutional framework for a consistent industrial policy taking into account the climate and environmental components, including carbon accounting. Russia is a country with high intensity of production-based CO2 emissions. In is well-known that the industry generates necessary hence it induce demand for products from other sectors of the economy. Environmental and social parameters in the formation of industrial policy should not be considered as any limitations for the development of industry. Despite a serious change in the agenda for the industrial policy in recent years, caused by COVID-19 and by current geopolitical situation in the world, it is highly undesirable to lag behind in this area, since it is necessary for international cooperation and human technological development. Low-carbon areas correspond to the modern ideology of industrial policy for many countries. The novelty of the study is the evaluation of the total GHG (greenhouse gases) intensity of Russias industry by means of intersectoral model. The paper analyses some of industrial policy measures and their implementation that affect low-carbon economic development. The proposed study could be of interest for other economies aiming to reduce their carbon footprint. © 2022 International Multidisciplinary Scientific Geoconference. All rights reserved.
ABSTRACT
When participants were then prompted to read information from different sources about vaccine efficacy against new COVID-19 variants, Trump supporters who had been shown the summary of Nature's editorial were less likely to trust Nature's information on COVID-19, and also reported more mistrust in US scientists. Trump had laid waste to science and scientific institutions at home on issues from COVID-19 to climate change, and had gutted environmental regulations even in the face of increasing climate risk. When individuals seeking office have a track record of causing harm, when they are transparently dismissive of facts and integrity, when they threaten scholarly autonomy, and when they are disdainful of cooperation and consensus, it becomes important to speak up.
ABSTRACT
This study constructs a digital economy (DE) index and explores its impact on environmental quality by utilizing data from China's 287 prefecture-level cities from 2013 to 2019. Unlike past studies, this research examines the indirect effect of DE on environmental pollution through the channels of industrial structure and educational investment. Further, it also analyzes the moderating role of economic globalization and green technology innovation in the nexus between DE and environmental quality. The empirical results indicate that DE significantly and positively enhances environmental quality by mitigating environmental pollution. This outcome remained stable after a series of empirical analyses and stability checks. Secondly, DE positively affects ecological and environmental quality by improving education levels and upgrading industrial structures. Thirdly, green technological innovation and economic globalization positively and significantly moderate the effect of DE development on ecological and environmental quality. Fourthly, associations between the development of DE and environmental quality are heterogeneous in terms of regions and markets, among which the most significant impact exists in the eastern area and the area with higher marketization. Based on the empirical findings, this paper provides comprehensive recommendations for promoting the DE and advancing China's environmental quality. Based on the results, important policy implications are suggested.
ABSTRACT
An environmentally friendly city is a livable home for the future. Can the rapidly developing digital economy help decrease carbon emissions and realize a low-carbon and clean city promptly? This study focuses on examining how multi-dimensional digital economic growth has influenced CO2 emissions across 280 Chinese cities from 2011 to 2019. Findings discover that (1) An "n”-type curve nexus exists between CO2 emissions and the digital economy in Chinese cities, which means that digital economy expansion initially strengthens CO2 emissions, but at a certain level, it can help achieve the target of urban decarbonization;(2) The digital economy's influence on CO2 emissions is spatially spilled and regionally heterogeneous, and by means of economies of scale and industrial composition upgrades, it can help the city to lower carbon emissions and benefit the low carbonization of neighboring cities. However, based on the "rebound effect”, the intermediary role of technological effects in reducing emissions in the short term is not apparent;(3) The expansion of trade openness and appropriately stringent environmental rules in line with national conditions are beneficial to lower CO2 emissions in the city and the surrounding cities in the short term. It is recommended that policy makers actively promote the development of the digital economy, strengthen exchanges and cooperation between cities, narrow the gap between cities, and actively learn the advanced management concepts of surrounding cities through the development of economies of scale and industrial structure transformation to accomplish the target of "carbon neutrality” sooner rather than later.
ABSTRACT
The drastic growth of cruise tourism in the world, while potentially beneficial for economic growth in local communities, also brings concerns regarding environmental impacts. This research used the port of Ísafjörður, Iceland, a growing hotspot destination for cruise ships, as a case study to aid in understanding the potential environmental impacts from cruise ships. The study's aims were: 1) to determine the quantity and type of waste discharged to the shore facilities by cruise ships in Ísafjörður in 2019, and 2) to explore the compliance behavior of the ships in adhering to Icelandic and international environmental regulations. To do this, quantitative and qualitative questions were presented in a survey to officers from 40 cruise ships, accounting for 87% of the total 46 different ships that docked in Ísafjörður in the 2019 cruise ship season. The survey questions were designed based on the MARPOL Convention and the law of Iceland, and these questions were compared with the ship's statutory record or ship's certificates to strengthen the reliability of the data. The questions covered five categories: emissions, waste oil, wastewater, garbage and food waste, and ballast water. Results showed that very little garbage and food waste had been discharged to shore facilities, and this was likely because Ísafjörður is one of several stops for many cruise ships in Iceland and the waste had simply been discharged elsewhere. In assessing the other four categories, 8 out of the 40 cruise ships carried out illegal activities, including 12 specific violation cases. This article discusses three primary reasons for those violations: accessibility, inconsistency, and monitoring. This research was conducted pre-COVID-19;however, by 2022 cruise ship calls in Ísafjörður approached preCOVID-19 numbers. Interested parties such as local communities, national decision makers, tourism boards, municipal planners, and environmental agencies must use the best available knowledge, such as this study, to manage the positive and negative aspects of the growth of cruise ship tourism, and perhaps even more so in a post-COVID-19 phase.
ABSTRACT
Se espera que la reactivación de la actividad industrial para recuperar la economía post-Covid-19, origine un incremento en los gases de efecto invernadero como consecuencia del uso de recursos naturales no renovables como carbón, petróleo y gas natural. En Colombia, sin embargo, la matriz energética ha mantenido una proporción de capacidad instalada relativamente constante favoreciéndose la energía producida a partir de fuentes hídricas (68% de energía proveniente de hidroeléctricas, 31% de termoeléctricas y 1% de energía eólica y solar). Considerando el potencial del país para el desarrollo de las energías renovables no convencionales, esta investigación busca revisar las políticas públicas vigentes para la adopción y promoción de estas formas de energía como parte de la transición energética hacia fuentes de energía que minimicen aún más los aportes de Colombia al cambio climático. Se realizó una investigación documental y descriptiva fundamentada en la información disponible en fuentes académicas e institucionales reseñada entre el año 2014 y el 2022. Los resultados indican que Colombia tiene un marco legal normativo importante que inicia con la Ley 1715 del año 2014, evolucionando hasta el presente con los aportes de las normativas generadas por la Comisión de Regulación de Energía y Gas (CREG) y la Unidad de Planeación Minero Energética (UPME), entre otras. A partir del año 2019 se han generado decretos o leyes para mejorar los incentivos y facilitar la radicación de proyectos de generación de fuentes de energías renovables no convencionales.Alternate abstract:The reactivation of industrial activity to recover the post-Covid-19 economy is expected to cause an increase ingreenhouse gases because of the use of non-renewable natural resources such as coal, oil, and natural gas. In Colombia,however, the energy matrix has maintained a relatively constant proportion of installed capacity, favoring energy producedfrom hydroelectric sources (68% of energy from hydroelectric plants, 31% from thermoelectric plants, and 1% from wind andsolar energy). Considering the country's potential for the development of non-conventional renewable energies, this researchseeks to review current public policies for the adoption and promotion of these forms of energy as part of the energy transitiontowards energy sources that further minimize the contributions of Colombia to climate change. A documentary and descriptiveresearch was carried out based on the information available in academic and institutional sources reviewed between 2014and 2022. The results indicate that Colombia has an important regulatory legal framework that begins with Law 1715 of 2014,evolving until the present with the contributions of the regulations generated by the Energy and Gas Regulation Commission(CREG) and the Energy Mining Planning Unit (UPME), among others. As of 2019, decrees or laws have been generated toimprove incentives and facilitate the establishment of projects to generate non-conventional renewable energy sources.
ABSTRACT
The root of Isatis tinctoria L. is highly appreciated as a Traditional Chinese herbal medicine for the prevention and adjuvant treatment of respiratory diseases caused by coronaviruses viruses such as SARS and COVID-19. I. tinctoria hairy root cultures (ITHRCs) provide a better alternative to field cultivation for the production of antiviral flavonoids. For the first time, ITHRCs were exposed to different colors of LED lights i.e., red, green, blue, red/green/blue (1/1/1, RGB), and white, in an attempt to promote the root growth and enhance the production of bioactive flavonoids. Results revealed that the biomass productivity (7.15 ± 0.63 g/L) in ITHRCs with an initial inoculum size of 0.2% cultured for 50 days under blue light increased by 1.86-fold relative to that under dark (control), and yields of rutin (320.49 ± 27.56 μg/g DW), quercetin (388.75 ± 9.17 μg/g DW), kaempferol (787.90 ± 83.43 μg/g DW), and isorhamnetin (269.11 ± 20.08 μg/g DW) increased by 4.15-fold, 9.31-fold, 9.09-fold, and 2.88-fold as compared with control, respectively. Interestingly, the emergence of adventitious buds was noticed in ITHRCs under all light treatments. Additionally, the enhanced densities of chloroplasts and root hairs were found in blue-light grown ITHRCs as against control, which might account for the elevated biomass productivity. Moreover, blue light induced oxidative stress in ITHRCs in terms of the overproduction of oxidation products and the enhancement of antioxidant enzyme activity. Furthermore, blue light significantly activated photoreceptor (CRY1) and key regulator of light signaling (HY5), thus leading to the up-regulated expression of MYB4 and structural genes (such as CHS and FLS) responsible for flavonoid biosynthesis. And, the transcriptional activation of CUC1 was likely related to the formation of adventitious buds in ITHRCs. Overall, the simple supplementation of blue LED light makes ITHRCs more attractive as plant factories for obtaining higher productivity of biomass and medicinally important flavonoids. © 2023 Elsevier B.V.
ABSTRACT
Resource-based cities (RBCs) are not only important for ensuring national resource and energy security, but they also face serious ecological and environmental problems. To achieve China's carbon peaking and neutrality goals in the coming years, RBCs' achievement of a low-carbon transformation has become increasingly significant. The core of this study is an investigation as to whether governance, including environmental regulations, can facilitate the low-carbon transformation of RBCs. Based on RBC data from 2003 to 2019, we establish a dynamic panel model to research the influence and mechanism of environmental regulations on low-carbon transformation. We found that China's environmental regulations facilitate a low-carbon transformation in RBCs. Mechanism analysis identified that the environmental regulations facilitate the low-carbon transformation in RBCs by strengthening foreign direct investment, enhancing green technology innovation and promoting industrial structure upgrading. Heterogeneity analysis found that the environmental regulations play a greater role in facilitating the low-carbon transformation of RBCs in regions with more developed economies and less dependence on resources. Our research provides theoretical and policy implications for environmental regulations for the low-carbon transformation of RBCs in China, applicable to other resource-based areas.

Sustainable development is central to the current societal functioning, whose complexity demands consideration on a regional scale. However, there are disparate methods to express sustainable development, many of which use qualitative analysis cumbersome for policy-makers. Previous studies focused on environmental, economic, and social impacts without fully considering the regulation mechanisms of the plethora of administrative bodies. To fill this research gap, this research establishes an integrated assessment framework involving four pillars: environment and ecology, society and culture, economics, and governance and policy. Further, indicator systems and quantitative analysis give comparable and objective results. The current study applied them to one of the most economically significant and developed Chinese regions, the Yangtze River Delta. The result shows a dynamic variation in regional sustainability from 2010 to 2019, indicating an annual increase. Although economic and societal development has been increasing steadily, environmental development has stagnated in the past two years, and the influencing policy has fluctuated dramatically. Our analysis was done in Shanghai, Jiangsu, Zhejiang, and Anhui. Even though all regions showed increasing sustainability, we observed an imbalance in regional sustainable development. Achieving a regional approach and enhanced regional coordination in the Yangtze River Delta is imperative and cannot be ignored by local, regional, and national policy-makers. More importantly, this study created a model capable of predicting the impact of the COVID-19 epidemic on regional sustainable development. The model showed that, compared with predicted values, a 6.65% decrease in the integrated sustainability index ensued, attributed to the pandemic in Zhejiang province. © 2022 Elsevier Ltd
ABSTRACT
Proposals on the inclusion of hydrogen as an energy vector into the large-scale energy socio-technical system has gained considerable momentum along with the effects of the climate crisis and the COVID-19 pandemic. This study examines the conflict between various dimensions of decarbonization with hydrogen agenda within the conceptual framework of international environmental law and policies. Firstly, we carry out a general due diligence of the technical, economic, and legal aspects of the hydrogen economy particularly in Europe. Subsequently, via textual analyses of European Union's strategic documents, the incompatibility of the hydrogen risk chain with the hydrogen value chain is revealed. Finally, as one remedy to this incompatibility;the precautionary principle, its relation to science, technology and society studies, and its possible policy applications in the context of hydrogen technologies are discussed. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.

ABSTRACT
PurposeThe rising food demand around the globe goes hand in hand with the rapid development of the agriculture industry. However, this development at the same time has detrimental effects on the natural environment. Hence, promoting ecological strategies in agriculture is essential for environmental sustainability. This study aims to investigate the institutional determinants of ecological strategies adopted by agricultural exporting firms and how these strategies enhance the firms' competitive advantage and financial performance.Design/methodology/approachA survey was conducted to collect data from 218 managers of agricultural exporting companies in Vietnam, which is a major exporter of agricultural products. The data were analyzed using different techniques including partial least squares structural equation modeling (PLS-SEM).FindingsThe results reveal that market pressure, regulatory pressure and competitive pressure motivate the adoption of ecological strategies among the surveyed agricultural exporting firms. Furthermore, such strategies help these firms obtain competitive advantage, which in turn increases their export financial performance. In addition, larger firms, compared to smaller firms, are more likely to adopt ecological strategies.Originality/valueThis study contributes to the literature by developing and validating a unique model examining the institutional pressures of ecological strategies and their outcomes in export markets. The study extends current knowledge about ecological exporting strategies for agricultural products, and its findings have several managerial and policy implications for promoting these strategies among agricultural exporting firms in emerging countries like Vietnam.
ABSTRACT
The Internet of Things paradigm envisions a world where every physical object is equipped with sensing/actuation capabilities and computing power and acquires its own digital identity. These objects are referred to as "smart” and have the goal of collecting and processing information about the environment surrounding them. One of the fields of interest in IoT applications concerns the intelligent management of activities in indoor environments, even if affected by unusual restrictions due to special conditions, such as those posed by the Covid-19 pandemic. This study focuses on the development of an IoT application based on the COGITO platform for the intelligent management of meeting rooms. By processing data collected from a set of IoT devices, cameras, and cognitive microphones, the developed prototype is able to autonomously monitor and make decisions about aspects that continuously affect environmental comfort, event management, and assessment of compliance with anti-contagious regulations throughout the time the room is occupied. After a brief review of the state of the art, the chapter describes the developed application. Furthermore, it highlights the features that make meeting room environments more comfortable for users and effective in managing events such as meetings and lectures. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
Since the establishment of the National Environmental Health Association (NEHA) on June 25, 1937 in Long Beach CA under the name of the National Association of Sanitarians, they have stood strong offering shelter to the profession from literal and political storms while lifting up the science and expertise of the workforce. Whether championing the first water regulations to reduce cholera and typhoid or modern water regulations to eliminate lead exposure, they walk alongside their members to provide the best science and practice and to raise their collective environmental health voice for the communities they serve. In 2021, they embarked on a journey to reflect on where the organization--and the workforce--has been over the past 84 years, including the impact of the COVID-19 pandemic. To keep themselves centered, they returned to the original NEHA charter to reflect on the wisdom of their professional forebearers. From this charter, they developed a new mission anchored on their history that reaches toward their future: To build, sustain, and empower an effective environmental health workforce.
ABSTRACT
This study empirically examined the effect of a carbon trading pilot market on export green-sophistication of Chinese listed enterprises by adopting a difference-in-difference method. Findings show that a carbon trading pilot market can improve enterprises’ export green-sophistication after using robustness tests to overcome endogeneity. The impact mechanism test shows that a carbon trading pilot market can improve export green-sophistication by increasing green technology innovation. Further research on the system design of carbon trading pilot markets shows that the greater the total carbon quota allocation, the larger the reduction in the trading volume of Chinese certified emissions. Furthermore, the weaker the punishment for an enterprise’s default in the pilot areas, the less favorable it is for enterprises to improve their export green-sophistication. Compared with the grandfather and historical intensity methods, benchmarking used in the allocation of carbon quotas is conducive to the improvement of the export green-sophistication of enterprises.
