    Abstract Food consumption has considerable impacts on the environment. Recently, increasing numbers of companion animal owners feed their animals with high nutritional food, which requires much land space and has great impacts on carbon emissions. Therefore, the environmental impacts of food consumption by companion animals can be significant, especially in a country with a large companion animal population, like China. In the present study, the ecological indicators of the ecological paw print (EPP), carbon emission and energy consumption have been introduced for the first time to quantify the environmental impacts of food consumption by companion dogs and cats in China. Our results showed that the dietary EPP and carbon emissions of an average-sized dog relying on commercial dry food (0.82–4.20 ha year −1 and 0.037–0.190 ton. year −1 ) were ca. eight and three times higher than those of the dog relying on human leftover food (0.11–0.53 ha year −1 and 0.014–0.064 ton. year −1 ). There were more than 27.4 million companion dogs and 58.1 million companion cats in China in 2015. Assuming all these dogs and cats eat commercial dry food, the dietary EPP of the total dogs and cats was 43.6–151.9 million ha. year −1 , which was equivalent to the dietary ecological footprint (EF) of 5.1%–17.8% (70.3–245.0 million) of Chinese people in 2015. The annual food consumption of all these dogs and cats was responsible for up to 2.4–7.5 million tons carbon emissions, which was equivalent to the entire carbon emissions of 2.5%–7.8% (34.3–107.1 million) of Chinese people in terms of food consumption in 2015. Our results also demonstrated that some companion animals (especially large dogs) consumed more food energy than their actual needs to keep normal activity, which resulted in food waste and exacerbated the environmental burden. This research develops an accurate method for companion animals' dietary EPP calculation and quantifies the significant environmental impacts by investigating their dietary carbon emissions and energy consumptions. Findings from this study will motivate companion animal owners to reconsider the feeding regimens and husbandry activities, improve owners and even the whole Chinese people's awareness of sustainability, and ultimately promote the whole country's sustainable development. Highlights We first quantified the dietary “ecological paw print” of pet dogs and cats in China. We first quantified the carbon emissions and energy requirement of these animals. The dietary EPP of two large dogs is equivalent to 20 Chinese people's dietary EF. The dietary EPP of all pet dogs and cats in China was 43.6–151.9 million ha. year −1 . The carbon emissions of all these animals in China were 2.4–7.5 million tons. year −1 .

    Abstract The analysis of the characteristics of carbon flows between regions is critical for China to deploy effective regional mitigation strategies. Different accounting principles exert a significant influence on China’s regional carbon emissions, especially the fairness of carbon emission reduction targets, and the responsibility for reducing emissions. An input-output model was established, based on the input-output data of 2007 and 2012, to evaluate the characteristics of regional carbon flow and the change in carbon emission from different industries, and to analyse the changes in carbon emissions under production-based, and consumption-based, principles in 30 provinces. The results show that the carbon emissions in each region and sector are different: from the eastern region to the western region they show a downward trend, and the embodied carbon flow accounts for a large proportion of the total. Secondary industries are a major contributor to carbon emissions and there is a signifiant influence exerted on the results of carbon emission accounting in various provinces of China under different accounting principles. Therefore, to meet national emission reduction targets, the provinces need to pay considerable attention to the choice of accounting principles and achieve the principle of fairness and impartiality. It will provide a reference for the future division of responsibility for carbon emissions in provinces of China.

    초록

    Abstract China has been undergoing unprecedented urbanization since the 1978 economic reform, with the present growth rate of 20 million people per year. This rapid and perennial progress has been raising concerns about environmental sustainability, due to a severe nationwide deterioration of China's environment and ecosystems in the context of ceaselessly increasing demand for water and energy. It is therefore of prime necessity and importance to comprehend China's water and energy security under the effect of dramatic demographic changes. Analyses of this issue still remain few and far between, and a comprehensive picture is not available that would help understand China's recent development in urbanization, its spatial features and links to water and energy security, particularly regarding residential consumption, and related national policy-making. Consequently, we address these knowledge gaps by performing an integrated and quantitative spatio-temporal analysis of the impacts of China's urbanization on water use and energy-related CO 2 emissions of residential consumption. We propose adding residential per capita water use and per capita energy-related CO 2 emissions as national indicators for policy-making targets of China's water and energy security. Over the study period of 2003–2012, per capita rural residential water use was on the increase, while urban use showed the opposite trend. Rural consumption has been remarkably higher than the urban, and this gap appears to be growing. In contrast, the per capita energy-related CO 2 emissions of residential consumption augmented significantly in both urban and rural areas nationwide. Besides, both the total and rural per capita residential water use and energy-related CO 2 emissions showed a significant positive correlation. However, in urban areas this correlation was negative. Highlights We assessed the impacts of China's urbanization on water-energy security. An integrated and quantitative spatio-temporal analysis was performed. Growing residential water consumption was found in rural areas nationwide. Both urban and rural areas had soaring residential energy consumption nationwide. Significant correlations of residential water and energy consumption were detected. Graphical abstract [DISPLAY OMISSION]

    Abstract In the past decade, sales of electrical and electronic equipment have undergone explosive growth worldwide, while at the same time, the life cycles of electrical and electronic equipment have been getting shorter. This has resulted in large numbers of waste electrical and electronic equipment (WEEE) being generated, which causes serious environmental problems that each country has to face. In this paper, we use the system dynamic method to analyze how China's “WEEE processing fund” policy, wherein levies or subsidies are set on appropriate targets, influences the economic and environmental conditions of participants in the WEEE management system. The simulations results suggest that the “WEEE processing fund” policy could improve the economic status of those receiving subsidies without losing the economic revenue from levies and improve the entire system's ability to recover and process waste equipment.

    Abstract Why are some firms more environmentally proactive than their counterparts from the same industry? What are these factors, which are responsible for the adoption of proactive environmental strategies which are beyond the requirement of extant laws? The power sector is a critical sector for the development of infrastructure in a developing economy like India. The emissions from the power sector are a cause of concern for the environmentalists and stakeholders. Some firms are observed to be more environmentally proactive than others even though the regulatory requirements are same. This paper aims to identify the determinants of the adoption of proactive environmental strategies in the power sector in India. The available studies are generalised and very few are sector-specific. No such research is carried out specifically for the power sector in India. Statistical tools like SPSS (Statistical Programme for Social Science) and AMOS (Analysis of Moment Structures) are used to analyse the quantitative data collected through a questionnaire-based survey from major power sector companies. Reliability and validity of data collected are checked using Exploratory Factor Analysis. Subsequently, Confirmatory Factor Analysis is applied to identify the determinants of adoption of proactive environmental strategies. The identified determinants are ranked using Structural Equation Modelling. The study identifies institutional pressure, performance improvement, business practices, and market pressure and benefits as determinants. Institutional pressure and performance improvement emerge as determinants which are ranked higher as compared to other two. The specific contribution of the study is to provide an understanding for the policymakers in Indian power sector to recognise these determinants in the formulation of policies and guidelines for environmental protection.

    Abstract PM2.5 emissions have serious adverse impacts on health and impede transport activities, especially air and highway. Consequently, policymakers and economists have focused on this issue. The primary objective of this study is to investigate the effect of democracy, political globalization, and urbanization on PM2.5 concentrations within G20 countries. Ecological modernization theory is used to gain the best understanding of the impact of these driving forces on PM2.5 concentrations and obtains an analytical framework. The method utilized is the panel quantile regression, which takes into account the unobserved individual and distributional heterogeneity. The results demonstrate that, first, the direct effect of democracy on PM2.5 concentrations is significantly positive in countries with higher emissions, and has no impact on lower-emission countries. Second, the direct effect of political globalization on PM2.5 concentrations is significantly positive and especially greater in extremely low- and high-emission countries. Third, persuasive evidence proves the existence of an environmental Kuznets curve between urbanization and PM2.5 concentrations. Additionally, this paper further assesses the direct and indirect influence mechanisms of democracy and political globalization on PM2.5 concentrations across pollution levels. Both have a positive (negative) indirect effect on PM2.5 concentrations in countries with higher (lower) emissions, through its effect on GDP per capita. The total effect appears positive, suggesting that the increase in democracy and political globalization degrade environmental quality. These results provide policymakers with critical policy recommendations that contribute to the reduction of PM2.5 concentrations and ensure sustainable economic development in the G20 countries. Highlights This article uses panel data to investigate the driving forces of PM2.5 concentrations in G20 countries. We examine the direct and indirect effect of democracy and political globalization on PM2.5 concentration across quantiles. Democracy significantly exacerbates environmental degradation in higher-emissions countries. Political globalization significantly increases PM2.5 emissions, especially in extremely low- and high-emission countries. An environmental Kuznets curve relationship exists between urbanisation and PM2.5 concentrations. Graphical abstract [DISPLAY OMISSION]

    Abstract Although innovation orientations are effective strategic postures in order to compete in marketplace, simply deploying high levels of innovation orientations does not always yield economic returns to new ventures. Drawing on the resource-based view and social network theory, this study aims at examining the relationships between innovation orientations (technological innovation and marketing innovation), external partnerships (technology partnership and market partnership) and start-ups’ performance. Using a sample of 132 low-carbon ventures located in Liaoning province, China, empirical results revealed that high levels of technological innovation and marketing innovation were positively related to start-ups’ performance. Meanwhile, there was no direct link between external partnerships and start-ups' performance. However, we found that external partnerships play moderating role that may alter the performance implications of innovation orientations. Our research findings provide several managerial implications for market practice and policy-makers.

    Abstract This work develops a small-scale microbial fuel cell (MFC) and evaluates their performance in series or in parallel as a tubular MFC (t-MFC) in removing benzene from groundwater and generating electricity. The results indicate that the time required (t r ) for t-MFC to remove all benzene was half of that required by a single MFC. The maximum power density (P max ) of the serially-connected t-MFC was 12.7 mW/m 2 , a 3.3-fold increase over the single t-MFC. An optimal benzene removal efficiency with a t r of four days was achieved under persistent aeration at the cathode of the t-MFC, and this t r was 1.25–3-fold lower than those obtained under other aeration conditions. Tubular MFCs connected in series had a higher open-circuited voltage (655 mV) and a lower t r , but the P max and maximum current density of the parallelly-connected t-MFC were 3.8 and 1.5 times those of the t-MFC with a serial connection. Intermittent aerating of the cathode improved the removal of benzene and the generation of electricity in a t-MFC by providing sufficient levels of oxygen for the reaction to achieve P max . The small t-MFC was easily scaled up by stacking MFCs in series mode, with great potential for field-scale application for in situ bioremediation in hydrocarbon-contaminated groundwater. Highlights Microbial fuel cells (MFCs) in series were easily scaled up for practical purposes. MFC performance was improved by adding coke to the carbon cloth-based cathode. MFCs were easily connected in series or in parallel to optimize MFC performance. Intermittently aerating on a cathode was a cost-effective way to supply oxygen. Graphical abstract [DISPLAY OMISSION]

    Journal of cleaner production v.194 ,pp. 85 - 93 , 2018 , 0959-6526 ,

    초록

    Abstract The use of reverse osmosis (RO) membranes has been significantly increasing because RO technology is a great option for the production of clean water for both domestic and industrial purposes, among water stress conditions and scarce clean water resources. The main solid waste from RO plants is membrane elements, which are often disposed of in landfills, and the large amount of waste needs to be properly managed. The objective of this study was to evaluate the environmental and economic gains of implementing end-of-life RO membrane recycling. The method applied the Material Input per Service Unit (MIPS) eco-efficiency tool. The recycling technique was based on chemical oxidation of thin-film-composite (TFC) RO membranes and was applied by immersion in a commercial sodium hypochlorite (NaClO). The recycled membrane showed similar performance and characteristics to porous membranes. Based on current market costs, the replacement of a new ultrafiltration membrane spiral element (with an average lifespan of 5 years) by the recycled membrane (with an estimated lifespan of 2 years) for water treatment results in monetary savings of 98.9%. MIPS indicated that chemical conversion of one 8-inch spiral element of an end-of-life RO membrane with 13.5 kg results in 2609.81 kg of materials not being polluted or withdrawn from the environment. The most important conclusion of this study is the possibility to have economic gains, associated with environmental benefits, arising from the use of recycled membranes. Highlights •Environmental issues regarding end-of-life RO membranes disposal are presented. •End-of-life RO membrane management in the near future may include recycling. •Quantitative information regarding end-of-life RO membranes recycling by means of chemical conversion is provided. •The possibility for environmental and economic benefits from implementing end-of-life RO membrane recycling is discussed.
