Grey relation analysis of carbon dioxide emissions from industrial production and energy uses in Taiwan

This study aims to identify key factors affecting energy-induced CO₂emission changes from 34 industries in Taiwan, in order to have an integrated understanding of the industrial environmental-economic-energy performance and to provide insights for relevant policy making in Taiwan. Grey relation analysis was used in this paper to analyse how energy-induced CO₂emissions from 34 industries in Taiwan are affected by the factors: production, total energy consumption, coal, oil, gas and electricity uses. The methodology was modified by taking account of the evolutionary direction among relevant factors. Furthermore, tests of sensitivity and stability, which are seldom discussed in most grey relation analyses, were conducted to ensure the reliability of outcomes. We found that values ranging from 0·3 to 0·5 are appropriate, and the analytical results with value of 0·5 offer moderate distinguishing effects and good stability. Results indicate that industrial production has the closest relationship with aggregate CO₂emission changes; electricity consumption the second in importance. It reveals that the economy in Taiwan relied heavily on CO₂intensive industries, and that electricity consumption had become more important for economic growth. The relational order of fuels is electricity, coal, oil then gas, accordant with their CO₂emission coefficients in Taiwan. The positive relational grade of aggregate production implies that the aggregate industrial CO₂intensity tended to decline. The total energy consumption had a smaller and negative relational grade with CO₂emissions, and implies an improvement on aggregate energy intensity, while the CO₂emission coefficient increased. For industries with significant influence on CO₂emissions, the total energy consumption had the largest relational grades. It is important to reduce the energy intensity of these industries. Nevertheless, it is also critical to decouple energy consumption and production to reduce the impacts of CO₂mitigation on economic growth.     

Engaging Economic Development Agencies in Environmental Protection: The case for embedded autonomy

This article examines the role of economic development agencies in strengthening the environmental performance of industry within rapidly industrialising East Asian economies. Three case-study examples are considered, namely, the role of the Industrial Development Board in reducing industrial pollution in Taiwan, pollution control in the palm oil industry in Malaysia, and the role of the Economic Development Board in influencing environmental performance of industry in Singapore. The concept of embedded autonomy is developed to consider the ways in which agencies of economic development can work with firms and industries while simultaneously remaining autonomous from these firms with respect to setting and enforcing performance standards. The three cases suggest that a form of policy integration that more directly integrates economic and environmental goals within agencies of economic development may be feasible, but only where there exists a strong autonomous government bureaucracy and where there is strong societal commitment to improving the environmental performance of industry.

Devising an integrated methodology for analyzing energy use and CO2 emissions from Taiwan's petrochemical industries

Input-output modeling and multiplier analysis are used to assess Taiwan's five petrochemical industries, based upon their economic contribution and potential impacts on energy consumption and CO2 emission. In addition, a consolidated index system was developed for evaluating energy and economic efficiencies as well as targets for CO2 reduction. Results indicate that petrochemical materials (PM) make a major contribution to economic development, with lesser contributions from plastic materials (PL) and artificial fibres (AF). PM has the highest energy multiplier while PL has the largest induced potential for energy consumption. Plastic and rubber products (PP, RP) are relatively insignificant energy consumers. AF has the highest CO2 multiplier, and its induced potential for CO2 emission is the most significant. The consolidated index shows that the upstream petrochemical industries perform rather poorly in an integrated view of economic, energy, and CO2 emission, and should be seen as the primary targets for CO2 reduction. Investment of the petrochemical industries in Taiwan should be adjusted to improve energy efficiency, economic bases, and lower CO2 emissions.     

A review of the Nigerian petroleum industry and the associated environmental problems

Nigeria has abundant deposits of oil and natural gas and their exploitation has improved the economy substantially, but with serious environmental costs. Severe ecological damage has occurred in the Niger Delta area where most of the oil industries are based. Statutory rules and regulations for environmental protection applicable to the oil industry in Nigeria appear to be generally inadequate and ineffective. So far, air pollution has not been properly addressed. Natural gas is still being flared from many oil wells, with serious air pollution problems and a waste of this resource. The legal control of air pollution in the light of the ongoing operations of liquified natural gas (LNG) and compressed natural gas (CNG) projects is advised along with other measures for environmental quality, control and the conservation of resources.     

不完全竞争行业中的环境工具有效性研究:一个理论框架

各级政府贯彻落实绿色发展的理念,实现经济增长与环境保护的共赢,才能真正实现"绿水青山就是金山银山"。在经济"新常态"背景下,防治环境污染是个复杂而系统性的工程,需要进行经济追因与综合治理,其中,制定实施有效的环境政策工具尤为关键。本文把微观经济学中的双寡头产量竞争模型作为基准模型拓展用于环境经济分析,并把环境税、环境规制、排污权交易这三类主要环境工具对企业生产决策的影响纳入基准模型,旨在对比研究不完全竞争行业中环境工具的有效性问题。结果表明:主要基于市场机制的环境经济政策比行政色彩浓厚的环境规制更有效率。提高环境税率或排污权价格均能显著削减行业污染物排放量,如果环境税率恰好等于排污权价格,则环境税与排污权交易这两类环境工具的效力相等。这对进一步建立和完善我国尚处于探索或初始实施阶段的环境工具,促进石化、电力、钢铁等不完全竞争行业的主要污染物减排,具有一定参考价值和借鉴意义。     

Oil-Induced environmental Kuznets curve in organization of petroleum exporting countries (OPEC)

This study investigates the environmental Kuznets curve (EKC) hypothesis in 10 of the Organization of Petroleum Exporting Countries (OPEC). To realize the study’s aims a time series model is built based on the period 1977–2008, utilizing the ecological footprint as an environmental indicator and income, labour, capital, oil consumption and oil price as economic indicators. Employing the Autoregressive Distributed Lag (ARDL) approach, by comparing the short and long-run income elasticities, the EKC hypothesis is present in six OPEC countries namely Algeria, Iraq, Venezuela, Nigeria, Qatar and Kuwait. Moreover, the Toda–Yamamoto–Dolado–Lütkepohl (TYDL) causality tests outcome show that, after oil consumption, the most significant factors in increasing ecological footprint are labor and capital. This implies the relocation of pollution intensive industries to almost all of the OPEC countries. However, oil prices reduce environmental damage by its negative effect on the ecological footprint. From the outcome of this study it is important for the investigated countries to reduce their consumption of fossil fuel energy since it represents an important source of pollution. This can be achieved by allocating more labor and capital in projects and investments on renewable energy, energy efficiency and energy saving.     

Reducing anthropogenic environmental stresses: A review on cleaner production and industrial ecology

Cleaner production (CP) provides source control measures of minimizing the waste and emissions occurred by the production and processes. CP, which is also known by the term pollution prevention (P2), has been practiced for several years among various countries across the world. Practicing of CP in industries supports in optimization of materials utilization, lowering the energy consumption, and the reduction of emissions to air, water, and soil. CP provides a continuous and preventive environmental improvement for the organizations by focusing on the prevention rather than providing solutions, once the pollution has been occurred. Implementing CP in a business requires support from the employees from top to bottom levels in the hierarchy, to obtain a successful and long‐term outcome. Thus, CP is no longer considered as a standalone process and should be integrated in the entire business development activities, in order to improve the quality of life. CP can also be identified as a subset of industrial ecology, which focuses on designing the industrial processes, products, and services, in order to minimize the environmental concerns of the industrial activities. This article will provide an overview of the background of CP, the CP assessment methodology, and the concepts of industrial ecology.     

Environmental policy stringency,renewable energy consumption and CO2 emissions: Panel cointegration analysis for BRIICTS countries

ABSTRACT

The aim of this paper is to investigate the relationship between environmental policy stringency and CO₂ emissions in BRIICTS (Brazil, Russia, India, Indonesia, China, Turkey and South Africa) for the period 1993–2014 after controlling for renewable energy, fossil energy, oil prices and income. We believe that this is the first attempt to use the recently OECD-developed environmental policy stringency index to test the effectiveness of environmental stringency policy in reducing CO₂ emission in these countries. Applying the Panel Pooled Mean Group Autoregressive Distributive Lag (PMG-ARDL) estimator, we found an inverted U–shaped relationship between environmental policy stringency and CO₂ emissions. This suggests that initially strict stringent environmental policy does not lead to improvements in the environment but after a certain level or a threshold point, environmental stringency policy leads to improvement in environmental quality. Renewable energy consumption was negatively related to CO₂ emissions while fossil energy consumption and real oil prices and income were positively and significantly related to CO₂. Our findings suggest that strengthening the stringency of environmental policies and promoting renewable energy are effective ways of preventing environmental degradation in BRIICTS countries.     

Assessment OF SURFACE WATER QUALITY at Large Watershed Scale: Land‐Use,Anthropogenic, and Administrative Impacts

Understanding the impacts that influence water quality is critical to the development of best management practices at the large watershed scale. This study describes the spatiotemporal variation in surface water quality and identifies their main impact in the Haihe River basin, China. Multivariate statistical techniques are applied to analyze the similarities among the sampling sites and to identify the main pollution sources in surface water. Results show that: (1) the basin can be clustered into two regions, water quality being better in the mountainous vs. plain regions; (2) water quality improves due to implementation of a strict state policy on environmental pollution control, prodded by the hosting of the Olympic games in the cities of Beijing and Tianjin; and (3) agricultural and residential land uses as well as livestock‐breeding are the main sources affecting water quality in the mountainous regions, whereas rural waste discharge — including domestic waste sewage, human and animal feces, and solid waste — significantly influences water quality in the plain regions. The waste discharge of industrial factories may be a significant source of water pollution in the plain regions. Results indicate that the environmental management from pollution sinks and sources, long‐lasting legal framework, and adequate economic incentives should be improved to optimize the large‐scale watershed management under the background of the rapid development of countries like China.     

以电代煤的经济与环境效益分析

我国《能源发展战略行动计划(2014—2020年)》指出,加快构建清洁、高效、安全、可持续的现代能源体系,重点实施"绿色低碳"等四种能源发展战略,因此"以电代煤"将成为我国未来能源战略中的一项重要选择。本文运用技术经济分析法和排放系数法,计算了八大主要用能部门以电代煤的经济成本和环境价值。计算结果表明:各部门用电设备的初始投资和电力消费等经济成本是燃煤设备的初始投资及燃煤消费等经济成本的1.8~2.8倍,但是,以用电设备替代燃煤设备的环境价值非常可观。在考虑了环境外部性成本后,居民生活行业,商业,非金属矿物制品业,石油加工、炼焦和核燃料加工业,化学原料和化学制品制造业,以及非高耗能工业六个部门进行"以电代煤"在目前的情况下具有经济可行性,而有色金属冶炼和压延工业,以及黑色金属冶炼和压延工业"以电代煤"暂时不具有经济可行性。最后,提出了相关政策建议。     

Rural industries and water pollution in China

Water pollution from small rural industries is a serious problem throughout China. Over half of all river sections monitored for water quality are rated as being unsafe for human contact, and this pollution is estimated to cost several per cent of GDP. While China has some of the toughest environmental protection laws in the world, the implementation of these laws in rural areas is not effective. This paper explains the reasons for this implementation gap. It argues that the factors that have underpinned the economic success of rural industry are precisely the same factors that cause water pollution from rural industry to remain such a serious problem in China. This means that the control of rural water pollution is not simply a technical problem of designing a more appropriate governance system, or finding better policy instruments or more funding. Instead, solutions lie in changes in the model that underpins rural development in China.     

The Environmental Pollution Perception of Residents in Coal Mining Areas: A Case Study in the Hancheng Mine Area, Shaanxi Province, China

The environmental behavior of the residents depends on their perception of environmental pollution. Hence, it is important for scientific and policy experts to research on the impact of the environmental pollution perception of local residents. Owing to the richness of natural resources, Hancheng coal mine areas are abound in heavy industries, and environmental pollution is serious and typical in this area, thus, the residents are anxious about their health. Using questionnaires, this paper surveys the perception of residents living in the coal mine area. The influential factors of environmental perception were analyzed by the Rank Sum Test. The results were: (1) the majority of the residents in the coal mine area are not satisfied with their living environment. The perception order of pollution severity is: air pollution?>?noise pollution?>?sanitation?>?water pollution. The residents think that pollution is mainly caused by coal processing. Hence, coal mining is not the main reason of the pollution in the coal mine area. (2) Age and length of residence have significant positive effects on perceptions of air, water, and noise pollutions; whereas education has a significant negative effect on perceptions of water and noise pollutions, as well as sanitation. This phenomenon can be explained by the various cultural groups having varied perceptions on the environmental pollution. In addition, proximity to mine has significant negative effect on perceptions of water and noise pollution. In conclusion, the paper discusses the effects of demographical and social factors on the perception of environmental pollution and gives suggestions on the planning and management of the environment.     

节能环保产业政策工具评述与展望

节能环保产业是打赢污染防治攻坚战的重要支撑,也是推动经济发展的新兴绿色动能。本文利用瓦当设计的政策工具三分法,对当前节能环保产业政策工具进行了分类研究。当前,影响节能环保产业政策的工具主要包括管制型工具、经济型工具、信息型工具三个类型。管制型工具包括指标控制、强制性标准和监督考核等;经济型工具包括财政支持、税收优惠、价格政策、金融政策等;信息型工具包括技术推广机制、产品推广机制等。尽管我国已经初步建立了政策支持体系,但当前政策工具仍然存在一系列不足,管制型工具、经济型工具、信息型工具都有较大的改进调整空间,应当进一步形成规范、合理的管制型制度,以普惠为主而非补助为主的经济型制度,以提供信息服务为主的信息型制度,并以此促进节能环保产业健康、有序发展。     

中国三大城市群经济能源交通结构对比及其对大气污染的影响分析

本文从经济、能源、交通结构三大领域分析了京津冀、长三角和珠三角三大城市群的异同点,探究了结构性特征对大气污染的影响。结果表明:我国东部三大城市群中,珠三角的空气质量最优,长三角次之,京津冀最差,空气污染程度自南向北呈现阶梯状上升态势;能源规模和结构、工业规模和结构、交通规模和结构同步呈现自南向北逐步偏化石燃料、偏重工业、偏公路运输的结构性特征,与空气污染的阶梯分布在一定程度上相吻合。从时间来看,空气污染呈现历史性发展和累积特征;从空间来看,重工业规模大、比重高,化石燃料在能源消费结构中占比高,汽车保有量和船舶货物吞吐量快速增高是京津冀和长三角大气污染重于珠三角的内在结构性主因。在数据分析的基础上,本文从分区施策和结构调整两方面提出了大气污染防控对策建议。     

铅酸电池行业环保专项行动的环境与经济影响研究

"十五"以来,我国涉重行业高速发展,造成了严重的重金属污染和多起群体性污染事故。从2009年起,环保部等九部委连续四年对重金属排放企业违法排污行为进行环保专项行动。本文以2011年铅蓄电池行业环保专项行动为例,分析重金属污染治理的环境影响、经济影响和社会影响。专项行动对行业短期赢利能力和中小企业就业有一定负面影响,但是显著改善了行业产能利用率,提升了行业整体技术水平,提高了产业集中度,促进了空间布局向工业园区、向东部地区集中。总体来看,铅蓄电池行业环保专项行动达到了预期的环境和经济目标,行业发展从高增长、高代价的"非常态"模式进入相对可持续的中高速、低代价的"新常态"。"十三五"期间,要实现经济中高速增长和环境质量总体改善的双重目标,必须加强对高污染行业的环境管理。将行政执法与刑事执法紧密衔接,通过提高企业违法成本从源头遏制违法排污行为;根据污染企业的空间布局建设相应的环保机构,加强农村地区的环保能力;在欠发达地区要保持经济规划、城镇规划和环境规划的一致性,在区域协调发展过程中实现绿色发展。     

四川省企业环境经济效益的分析评价

目前对于企业环境经济效益的分析评价,缺乏科学易行的方法。本文根据污染物排放量与经济效益间的关系,提出了单位等标污染负荷利税法,即每排放单位等标污染物所产生的年利税值。据此对四川省6个行业44家企业的环境经济效益进行了统计分析,并对其应用Excel模糊聚类进行了分级评价。结果表明:不同企业间单位等标污染负荷利税值存在多个数量级差异。造纸、纺织企业环境经济效益最差,体现了行业性弊病。制药、建材、机械电子行业企业环境经济效益整体较好,但仍有部分"粗放型"企业环境经济效益差。部分机械电子、化工企业依赖技术革新,环境经济效益优良。与定性分析评价方法相比,单位等标污染负荷利税法更能发现"高产值、高污染"下的误区,该法结合应用Excel模糊聚类分析,可简易、客观分析评价不同企业、行业甚至不同经济规模单元间的环境经济效益。

Environment and Development in a Southern European Country: Which Environmental Kuznets Curves?

Environmental policy questions have been recently tied to the fast evolving literature on Environmental Kuznets Curves (EKCs). The EKC thesis advocates the existence of a U-inverse relationship between economic growth and environmental quality. This paper adopts a recent view that EKCs should be studied using individual country experiences and looks at the evolution of air pollution, agricultural pollution, fisheries depletion and forest destruction in Greece during the last two to three decades. The evidence indicates that either EKCs do not exist, or Greece is on the rising segment of a hypothetical EKC. Greece's entrance to the EU, however, has helped it identify environmental externalities and resource depletion problems.
