中国造纸及纸制品业碳排放因素分解与减排潜力分析

作为传统的高耗能、高排放行业之一,我国造纸及纸制品业的节能减排工作任重道远。基于2000—2015年对我国造纸及纸制品业碳排放状况的预测状况,运用LMDI模型对该行业碳排放变化的影响因素进行了分解,从优化能源结构视角预测了行业的碳减排潜力。结果表明:2000—2015年我国造纸及纸制品业CO_2排放呈现总量总体上升、强度逐步下降的态势;经济发展和劳动力供给是影响行业CO_2排放量增加的主要因素,能源强度和能源消费结构对行业CO_2排放的抑制作用显著。因此,进一步实施企业排放披露和监察政策、提升从业人员素质、推广低碳生产技术、改善能源供给质量和消费结构,是推进我国造纸及纸制品业绿色发展的可行途径。     

陕西:关停73家造纸厂之后

渭河流域共有造纸企业148家,现在却要“瘦身”一半。日前,陕西省环保局作出决定,关停渭河流域73家造纸企业,以减少造纸行业的污染物排放量。“这样和你说吧,不论从环保的角度还是从行业的角度看,这些企业关停就对了。”关停事件发生后,资深记者丁洋轻松地说。必须经历的阵痛根据陕西省环保局的普查,造纸业已成为渭河流域最大的工业污染源。2004年,渭河流域148家造纸企业污染物排放量占流域内工业污染物排放总量的60%以上。作为一位长期跟踪造纸行业发展的“圈内人”,丁洋认为关停这些企业的理由是非常充分的。“关停的73家,基本都是小企业,…

State ownership and the price sensitivity of supply: The case of the copper mining industry

The paper attempts to verify the claim that output in state owned copper mining industries is less sensitive to price changes than in private ones. This is done by comparing the price sensitivity of copper supply in countries with state and privately owned copper industries and by testing whether nationalization leads to changes in the supply behaviour of copper mining industries. It is found that low supply elasticities and nationalizations are both the result of a country's high dependence on copper and are not themselves causally related.

This paper introduces a special issue on ‘Corporate Social Responsibility in the extractive industries: experiences from developing countries’. Drawing upon case study analysis from Latin America, sub-Saharan Africa and Asia, the papers in this issue broaden understanding of how multinational mining and oil and gas companies have embraced the CSR challenge and responded to criticisms of their performance in developing countries. This paper provides an introduction to the debate on CSR in the extractive industries in developing countries, reviewing the key issues examined on this subject to date.     

Economic-environmental modeling of point source pollution in Jefferson County,Alabama, USA

This paper uses an integrated economic-environmental model to assess the point source pollution from major industries in Jefferson County, Northern Alabama. Industrial expansion generates employment, income, and tax revenue for the public sector; however, it is also often associated with the discharge of chemical pollutants. Jefferson County is one of the largest industrial counties in Alabama that experienced smog warnings and ambient ozone concentration, 1996-1999. Past studies of chemical discharge from industries have used models to assess the pollution impact of individual plants. This study, however, uses an extended Input-Output (I-O) economic model with pollution emission coefficients to assess direct and indirect pollutant emission for several major industries in Jefferson County. The major findings of the study are: (a) the principal emission by the selected industries are volatile organic compounds (VOC) and these contribute to the ambient ozone concentration; (b) the direct and indirect emissions are significantly higher than the direct emission by some industries, indicating that an isolated analysis will underestimate the emission by an industry; (c) while low emission coefficient industries may suggest industry choice they may also emit the most hazardous chemicals. This study is limited by the assumptions made, and the data availability, however it provides a useful analytical tool for direct and cumulative emission estimation and generates insights on the complexity in choice of industries.

Determinants of foreign direct investment in the mining sector in Asia: A comparison between China and India

The aim of this paper is to assess the conditions that influence foreign direct investment in the mineral industries of China and India. The paper first surveys literature on the determinants of foreign direct investment to identify key conditions, under which host countries attract mining FDI. It then builds an evaluative framework which allows for comparative analysis. The paper then comparatively evaluates the performance of foreign investment regimes that govern mineral industries in China and India. Its findings show that the overall conditions for foreign mining investment in China and India are not favourable and that substantial policy, regulatory and other changes in both countries need to be made if more investment is to flow.     

Methodology of industry scale analysis under the constraint of regional resource capacity using HSY algorithm

This paper develops a methodology of proper scale analysis for regional industry development, which can be used in industry planning with the consideration of regional resource capacities. In the face of different data sources and even data scarcity, alternative methods based on linear programming and quadratic programming algorithms for calculating the resource intensity factors are designed. Based on the empirical study of industrialization, initial scenarios of industry development were set. Using HSY algorithm, sensitive industries that may cause exceeding regional resource capacity can be identified, and the risk of exceeding can be predicted and expressed in probability. Furthermore, a proper scale range can be designed for these sensitive industries according to resource capacity. Taking the case of Dalian city in China, this paper estimated the regional urban development plan, various resources capacities were studied, and land resources were estimated to be the most critical resource for the city. The land resource depletion intensities of different industries are calculated by quadratic programming algorithm. Under the constraint of 427.56 km² available industrial land resources, the electronic and power industries have the most significant impact on total land use, if the scale of power industry exceeds 1.27 billion USD, the probability of land resource capacity breakthrough will be 50%.
