The aim of this paper is to analyse the environmental and well being impacts of consumption and production systems in Baltic Sea Region and draw conclusions about transferring of best practises in Latvia. This study is based on indicator analyses, focusing on data of environmental impacts from consumption and production in the region, and analyses drivers behind these impacts. The paper concludes two trends--Scandinavian countries and Germany which have more advanced economies demonstrate much higher ecoefficiency and environmental management practices compared to the new EU member states. The example of the Baltic Sea region shows that high income levels and a stable development path in the old EU member states provide grounds for technology advancement to reduce the environmental impact of production. However Baltic States and Poland on average demonstrate much more sustainable consumption patterns. But the trends in these countries are negative--they try to copy lifestyles and consumption patterns of more advanced economies with higher ecological footprint. Challenge for Latvia is to improve its ecoefficiency but at the same time develop more sustainable consumption patterns.展开更多

In this paper,based on TPB( Theory of Planed Behavior),using factor analysis and regression analysis,empirical test on formation mechanism of farmer production consumption ecologization behavior transformation is conducted. Research results show that behavior attitude,subjective norm and control cognition of farmer production consumption ecologization have significantly positive influences on behavior response of farmer production consumption ecologization. Among them,power of behavior attitude is farmer's economic rationality and ecological rationality; power of subjective norm is system norm,government guidance and social pressure; power of control cognition is policy judgment and ability perception. Finally,for the analyzed conclusions,policy suggestions are proposed from many aspects,which could provide reference effect for guiding farmer production consumption ecologization and establishing rural eco-civilization.展开更多

The result of the model showed urban residents' annual disposable income and having meals out of home play the greatest effect on the consumption of aquatic products, followed by the number of retail chains stores; family structure plays a negative effect on the consumption of aquatic products. Also, the analysis shows not only the prices of the aquatic products as well as substitutes should be considered and also the quantity of the meals consumed by residents out of home and the number of retail chains stores should be used as important associated factors in studying the change trend of aquatic products consumption, and simultaneously the effect of family structure on the consumption quantity of aquatic products should be taken seriously, so that the aquatic products consumption of Chinese residents should be further promoted and also the aquatic products market can attain a development.展开更多

To build an ISM of a production system, the partial correlation coefficient method is proposed to obtain the adjacency matrix, which can be transformed to ISM. According to estimation of correlation coefficient, the result can give actual variable correlations and eliminate effects of intermediate variables. Furthermore, this paper proposes an effective approach using ISM to analyze the main factors and basic mechanisms that affect the energy consumption in an ethylene production system. The case study shows that the proposed energy consumption analysis method is valid and efficient in improvement of energy efficiency in ethylene production.展开更多

The indicators such as Direct Material Input(DMI), Direct Material Consumption (DMC) and Exports are calculated or estimated for the period of year 1995 through 2004. Several derivable iudicators defining direct material productivity and material intenstiy are also evaluated and some valuable conclusions were drawn. DMI in absolute number increased from about 1645.9 kilotons in 1995to about 8052.5 kilotons in 2004. Imports contribute to about 47 to 69% of DMI, and the biggest component of imports is fossil fuel that approximatley accounts far 50% of imnports. DMI per capita of Chengyang District increased rapidly and reached 17. 4 tons in 2004. Compared with other five economies studied by WRI, material consumption intensity of Chengyang District is significantly lower than developed countries, which indicates that Chengyang District is still in a development stage The direct material productivity (actual GDP per DMI) increased 59.1% from 1995 to 2004 and has been higher than either of stadies in China, which indicates efficiency of resources utilization has improved obviously in Chengyang District. But there was significant increase in material input in the last decade, which shows that rapid increase of economy is highly dependent on requirement and consumption of natural resources. Therefore, in order to promote the sustainahility, it is essential to develop circular economy and improve utilization efficiency of resources.展开更多

Some recent initiatives at global, regional and local level are pointed and some conceptual trends and deployment strategies advance towards the consolidation of the principles of sustainable development, despite several difficulties for effectively reaching its goals. The trend of gradual changes in the models of developing nations and in the patterns of production and consumption is portrayed objectively, seeking to correlate with principles of environmental economics and green economy, since Cecil Pigou and Stuart Mill principles to recent researches as Kenneth Boulding, Herman Daly, Nicholas Georgescu-Rogen, Franz Capra, Ignacy Sachs, Edgar Morin, beyond others. The ability of the United Nations and governments to intervene in neoliberal logic aiming wider benefit to society and the reduction of the negative effects of market distortions, as striking on the global stage, represents a true redemption of the principles advocated by Cecil Pigou, at the beginning of the last century, both for the global economy and for their effects on environmental and social conflicts, social exclusion resulting from the current economic systems which are not necessary new strategies, principles, or economic formulas, but decision making to tackle the market with seriousness to promote equity, social justice and environmental sustainability, without sacrificing progress and development, as evident in the current discussion of social inclusion and the convergence of individual and collective interests, so far in the development model based on increasing production and consumption, yet with little environmental responsibility.展开更多

Therefore, a generic process-level input-output (IO) model was developed to provide an integrated energy (material) accounting and analysis approach for industrial production processes. By extending the existing processlevel IO models, the production, usage, export and loss of by-products were explicitly considered in the proposed IO model. Moreover, the by-products allocation procedures were incorporated into the proposed IO model to reflect individual contributions of products to energy consumption. Finally, the proposed model enabled calculating embodied energy of main products and total energy consumption under hierarchical accounting scope. Plant managers, energy management consultants, governmental officials and academic researchers could use this input-output model to account material and energy flows, thus calculating energy consumption indicators of a production process with their specific system boundary requirements. The accounting results could be further used for energy labeling, identifying bottlenecks of production activities, evaluating industrial symbiosis effects, improving materials and energy utilization efficiency, etc. The model could also be used as a planning tool to determine the effect that a particular change of technology and supply chains may have on the industrial production processes. The proposed model was tested and applied in a real integrated steel mill, which also provided the reference results for related researches. At last, some concepts, computational issues and limi- tations of the proposed model were discussed.展开更多

The ability of the United Nations and governments to intervene in neoliberal logic aiming wider benefit to society and the reduction of the negative effects of market distortions, as striking on the global stage, represents a true redemption of the principles advocated by Cecil Pigou, at the beginning of the last century, both for the global economy and for their effects on environmental and social conflicts, social exclusion resulting from the current economic systems which are not necessary new strategies, principles, or economic formulas, but decision making to tackle the market with seriousness to promote equity, social justice and environmental sustainability, without sacrificing progress and development, as evident in the current discussion of social inclusion and the convergence of individual and collective interests, so far in the development model based on increasing production and consumption, yet with little environmental responsibility.
文摘Over the past two decades, the consumption of animal products has increased rapidly in China and India, driven by rising income and large populations. Such strong demand for animal products could have substantial impacts on both their own and global food and feed demand and supply. This paper examines the nature of rising demand for animal products in China and India and discusses national and global implications.
文摘To promote sustainability, it has become increasingly vital to properly account material and energy flows in industrial production processes. Therefore, a generic process-level input-output (IO) model was developed to provide an integrated energy (material) accounting and analysis approach for industrial production processes. By extending the existing processlevel IO models, the production, usage, export and loss of by-products were explicitly considered in the proposed IO model. Moreover, the by-products allocation procedures were incorporated into the proposed IO model to reflect individual contributions of products to energy consumption. Finally, the proposed model enabled calculating embodied energy of main products and total energy consumption under hierarchical accounting scope. Plant managers, energy management consultants, governmental officials and academic researchers could use this input-output model to account material and energy flows, thus calculating energy consumption indicators of a production process with their specific system boundary requirements. The accounting results could be further used for energy labeling, identifying bottlenecks of production activities, evaluating industrial symbiosis effects, improving materials and energy utilization efficiency, etc. The model could also be used as a planning tool to determine the effect that a particular change of technology and supply chains may have on the industrial production processes. The proposed model was tested and applied in a real integrated steel mill, which also provided the reference results for related researches. At last, some concepts, computational issues and limi- tations of the proposed model were discussed.
文摘China is the world’s largest producer of copper processing products as well as the world’s largest copper consumer market.In 2013,China produced more than 13.60 million tons of copper processing products,accounting for60%of the world’s total production.Since then,this proportion has expanded year by year,and will increase to about 66.7%in 2016.Meanwhile,China consumed nearly 11
