我国环境污染日益严重,政府加大环境保护力度势在必行,科学、有效的环境管理对保护环境、提高环境质量起着重要的作用。环境技术进步是环境管理有效且持久的驱动力,但是,环境技术进步的测度方法一直未能实现普适性。本文首先综述了技术进步对改善环境质量的重要性,在此基础上,阐述了各学者对技术进步和偏向型技术进步测量方法的探究。然后介绍了大数据在环境管理中的应用,在其应用经验的基础上,将其引入环境技术测度领域。大数据在该领域的应用为环境偏向型技术进步的测度提供了新的契机,同时,大数据的应用也增加了研究的困难性。最后,基于偏向型技术进步之间的矛盾,提出最优环境技术的理念。通过利用大数据,可以合理测度偏向型技术进步,实现生产偏向型技术进步和环境偏向型技术进步的合理配比,找出可以兼顾高产出和低污染物排放量的最优偏向型技术进步模式。并进一步结合各区域的差异性和关联性,能够测算出区域最优偏向型技术进步模式,找到有效的环境管理方式,为环境管理者与政策制定者提供合理参考。  相似文献

Environmental Management Systems (EMS) are being trialed for Australian agricultural industries as society becomes more concerned about agricultures environmental performance. EMS is a structured approach used by farm businesses to assess, monitor, and improve environmental performance. Use of EMS in conjunction with other policy tools (such as financial incentives and regulation) in agriculture could enhance management of both on-farm and off-farm environmental issues. Based on the international standard ISO14001, EMS was designed to be applied at the individual business level. However, governments in Australia are exploring its potential to be applied at a catchment scale, among other things, for the purpose of linking farm-level actions to catchment targets. In Australia, governments and catchment management bodies are using Integrated Catchment Management (ICM) as the framework to try to achieve environmental targets set out in catchment plans. In this article, we compare aspects of the EMS and ICM frameworks and comment on the potential of using EMS to achieve catchment-scale environmental outcomes. We conclude that EMS could be a useful policy tool to improve farm management and to contribute, in part, to better off-site outcomes at the catchment/landscape scale. Recommendations on the use of EMS at the catchment scale are discussed. These include using an educational approach for EMS delivery, linking the EMS process to catchment targets, and ensuring catchment targets are realistic and achievable.  相似文献

Environmental impact assessment and management in the mining industry   总被引:3,自引:0,他引:3  
The mineral industries have always had significant environmental problems. Dealing with them is in many cases technically possible, but the cost is often prohibitive in an industry with uniform products and much trade. As a possible solution, it is suggested to make mineral products less uniform and more distinguishable in terms of the environmental impacts involved in producing a specific shipment or volume of mineral; this could be combined with means to identify each shipment. Such action would require identification techniques and, more particularly, clear and unequivocal evidence regarding environmental impacts at all stages of production.  相似文献

Many management processes and tools can provide companies with information to support their environmental decision making. Risk assessment, environmental auditing, life cycle assessment and environmental reporting are but a few examples. Each of these has typically evolved independently as the need for it has arisen. Today, however, this abundance of tools can lead to confusion: What is the exact objective of each tool? How do they differ? Are some ‘better’ than others? Should they be used in parallel, sequentially or in place of each other? More importantly, how do they fit together into a coherent environmental management framework that will ensure sound environmental and economic decision making in a company? This paper seeks to answer these questions. It describes the overall environmental framework that has been developed internally within Procter & Gamble and which allows the company to make coherent economically and environmentally sound decisions, in both the short- and long-term.  相似文献

The environmental performance of the University of Maribor (Engineering Campus) has been assessed on a life cycle basis. The following activities have been considered in the study: the use and operation of lecture theatres (construction and maintenance, heating, lighting and water consumption) and day-to-day consumption of sundries (paper and plastic bottles). The results indicate that the heating and construction of buildings are the ‘hot spots’ in the system, for most environmental impacts. Different waste management options for the plastic and paper, including recycling, incineration and landfill, have also been compared for environmental impacts and economic costs. The option combining 70% recycling, 29% incineration and 1% landfill has been found to be most economically and environmentally sustainable.  相似文献

Over the past two decades, communication on environmental values, actions and performance has become an essential activity of organisations, because of the increased public concern and legislation related to the environment.

Stakeholders put pressure on companies to take environmental responsibility. In this framework, an effective environmental communication can generate value-added on companies' environmental work, and consequently, their competitiveness and profitability can benefit from communicating their environmental responsibility.

In 2006, the International Organization for Standardization (ISO) launched a standard for environmental communication, ISO 14063. ISO 14063 should not be used for third-party certification purposes. Instead, it is intended to be used as a guideline and support companies to ensure successful environmental communication. The aim of this paper is to prompt a discussion about the applicability of the standard ISO 14063 not only to single organisations but as a tool to plan the environmental communication strategy of a whole territorial area. This is achieved by performing a case study relating to the Interreg IVC-funded project “Progresland”. The project involved three Italian and one Spanish natural areas and demonstrated that ISO 14063 could be a valid support to define and implement an environmental communication plan for a territorial area.  相似文献

Although environmental management in Turkey is evolving, its performance needs to be assessed in terms of the extent to which polluters and dischargers are complying with their legal obligations. In spite of this necessity, however, not a single study evaluating the effectiveness of command-and-control strategy of environmental management has been conducted. It is for this reason that it was decided to conduct an analysis of the impact of environmental legislation on a major industrial area in Turkey. Accordingly, Turkish environmental legislation was analyzed, and all relevant obligations and responsibilities of industry are identified. Based upon this appraisal, a questionnaire was prepared and used to conduct interviews in Tuzla, Istanbul. From the results, it can be concluded that environmental compliance performance of industry is low. The total of 92 parameters has been questioned. Fifty-three parameters have been found as satisfactory compliance, whereas 26 parameters have been classified as partial compliance and 13 as unsatisfactory compliance. The most important reason for inadequate performance is the lack of an effective national and local environmental compliance management system. The other leading reasons are found to be low-level environmental consciousness of the people, absence of environmental management system at the sites, inadequacies in environmental subsidies, and insufficiencies in public environmental infrastructure. Four recommendations are made to increase the effectiveness of compliance management: establishing an effective environmental compliance management system, accelerating public investment for environmental infrastructure, developing financial subsidies and incentive schemes for environmental investments, and encouraging voluntary initiatives.  相似文献

The efficacy of government-supported programs to encourage improved management of land and water systems associated with agricultural land in Australia has been mixed. The broad approach of Australian governments is reviewed briefly. Evidence is presented from case assessments of a program to promote adoption of environmental management systems (EMSs) to improve environmental outcomes from agricultural practices. EMSs are systems implemented to manage the environmental impacts and ameliorate environmental risk associated with business activity. Data are presented on reported EMS activity and experience of four selected groups of farmers in Victoria, south-eastern Australia, representing broad-acre cropping, beef and dairy farming. The pro-environmental behaviours of farmers were mediated through voluntary adoption of government and industry sponsored EMSs, often with financial incentives and other support. Findings from the study were that adoption of EMS practices with sufficient public benefits is unlikely to occur at sufficient scale for significant environmental impact. Farmers more readily adopted practices which were financially beneficial than those which had a positive environmental impact. Although the focus on voluntary market-based instrument (MBI) type programs is popular in western countries, enforcing regulation is an important, but usually politically unpopular, component of land use policy. The comparative advantage of EMSs differed for the industries studied, but overall there were insufficient market drivers for widespread EMS adoption in Australia. Environmental outcomes could be more effectively achieved by directly funding land management practices which have highest public net benefits. Having a clear and unambiguous management objective for a particular land management policy is more likely to achieve outcomes than having multiple objectives as occurs in a number of international programs currently.  相似文献

The debate concerning the environmental effectiveness of environmental management systems (EMS) based on ISO 14001 is still open and scholars have called for further studies that can explain the contrasting evidence in previous research. As a response, this study aims to contribute knowledge about the effects of ISO 14001-based EMS by presenting fact-based environmental data. The study focuses on changes in performance over a period of 12 years and includes both firms with an EMS (66 firms) and firms without one (50 firms). Consideration is given to the improvement efforts in the firms before EMS adoption making it possible to neutralize any selection effects where better environmental performance precedes ISO 14001 adoption. Analysis has been carried out using statistical methods for six different environmental areas. No statistically significant differences between certified and non-certified firms concerning the change in the rate of improvement could be found in any of the six areas. However, it can be suspected that EMS adoption has positive effects on energy use and waste production whereas the non-adopting firms seem to perform better concerning air emissions. These mixed results mirrors previous research, which is rather worrying considering the worldwide popularity of EMS based on ISO 14001 in industry.  相似文献

日本与我国在历史上同属传统的东亚小农经济国家,在社会、经济、文化等方面的发展历程和存在的问题具有共通性。日本的农村生态环境管理随社会经济发展不断调整适应,政府也数次推动乡村振兴。对比研究中日两国农村环境管理及其背后的社会经济因素,虽然两国在农村环境管理上有相似性,但也有较大不同,我国不能完全照搬日本的农村环境管理体制机制,必须走一条适应我国国情的特色道路,循序渐进推进农业农村污染防治。在开展农村环保工作的具体举措上,日本也有较多可借鉴之处:一是以完善的法规政策体系保障农村环境管理;二是以精准的财政补贴支撑农村环境管理;三是以科学的规划和技术标准体系服务农村环境管理;四是以规范的行业和市场服务体系推动农村环境管理;五是以亲民务实的环境宣传教育助力农村环境管理。  相似文献

Mismanagement of Agrochemicals Plastic Packaging Waste (APPW) constitutes a major environmental problem, resulting in the pollution of soil, air and water resources and compromising the agricultural products safety, the protection of the environment and the public health. Systems for the management of APPW have been established in some European countries and they are operational for several years now. However, these schemes are incompatible while their operational conditions and technical criteria could be improved. In many countries no schemes exist yet for the management of APPW with serious negative consequences for the environment and public health. In response to these problems the European project AgroChePack has developed an environmental friendly, economically viable European APPW management scheme by transferring know-how from existing schemes, designing a new integrated APPW management scheme and testing it through pilot trials in five countries. This work presents the basic design principles established by AgroChePack by identifying problems and bottlenecks faced by existing schemes in Europe, by developing an integrated APPW scheme and by implementing, evaluating and optimising this scheme through pilot trials in Greece.  相似文献

Alternative scenarios to meet the demands of sustainable waste management   总被引:1,自引:0,他引:1  
This paper analyses different alternatives for solid waste management that can be implemented to enable the targets required by the European Landfill and Packaging and Packaging Waste Directives to be achieved in the Valencian Community, on the east coast of Spain. The methodology applied to evaluate the environmental performance of each alternative is Life Cycle Assessment (LCA). The analysis has been performed at two levels; first, the emissions accounted for in the inventory stage have been arranged into impact categories to obtain an indicator for each category; and secondly, the weighting of environmental data to a single unit has been applied. Despite quantitative differences between the results obtained with four alternative impact assessment methods, the same preference ranking has been established: scenarios with energy recovery (1v and 2v) achieve major improvements compared to baseline, with scenario 1v being better than 2v for all impact assessment methods except for the EPS'00 method, which obtains better results for scenario 2v. Sensitivity analysis has been used to test some of the assumptions used in the initial life cycle inventory model but none have a significant effect on the overall results. As a result, the best alternative to the existing waste management system can be identified.  相似文献

This paper discusses the environmental waste management of the Heap-Leach Uranium Production Facility of Caetité located in a semi-arid region in Brazil. A comparison is made with the first uranium production site of the country located in Poços de Caldas. It is demonstrated that differences in the operational process along with different environmental conditions can lead to different impacts. In the present case groundwater is the potential most sensitive environmental medium despite the well-established consensus in the literature that radon and aerosol emissions may turn-out to be the most relevant environmental aspects of an installation located at this type of region. Most of the 226Ra content in the ore remains in the leached ore that is deposited with the waste rock. A lack in appropriate prediction of the hydrological balance has been causing unanticipated emissions of liquid effluents into the environment. Chemical treatment of this effluent may be needed. Contamination of groundwater in the short term by the waste ponds is not to be expected but it can be a relevant issue in the long term. As a consequence, careful closure schemes will need to be put in place. Finally, the overall costs with remediation in the Caetité production center are lower than those observed at the Poços de Caldas mining site.  相似文献

The aim of this research is to verify the relationship between the maturity levels of environmental management and the adoption of green supply chain management (GSCM) practices by electro-electronic companies in Brazil. In this work a two-phase research was conducted, with one quantitative and the other qualitative. The quantitative phase aimed to test whether a relationship between the maturity levels of environmental management and GSCM exists, while the qualitative phase tried to detail the characteristics of this relationship. The quantitative phase was conducted through a survey with 100 Brazilian electro-electronic companies and the collected data were processed using Structural Equation Modeling. For the qualitative phase, a multiple case study was conducted with three companies located in Brazil. The results indicate that: (1) The main hypothesis was confirmed and considered statistically valid, indicating that, indeed, the maturity level of environmental management influences the adoption of GSCM practices; (2) a coevolution tends to occur between the environmental maturity and the GSCM practices; that is, the more developed is the company's environmental management, more complex GSCM practices are adopted; and (3) the GSCM internal practices tend to present a greater relative adoption than the external practices; these external practices of GSCM tend to be adopted when the company is inserted in a higher environmental stage and/or operates under a scenario of stronger normative environmental pressure. By the way, this is the first research mixing survey and case studies on GSCM in Brazil.  相似文献

Multivariate analysis of variance, canonical correlation and canonical discriminate analysis were performed on environmental data collected from the Kuwaiti intertidal zone to determine the statistical relationships between the sediment, chemical, biological, spatial and temporal variables. The quantitative analysis showed that the sediment type was the paramount factor influencing the distribution and composition of the intertidal benthic fauna. The muddy, sandy and rocky shores support three distinct faunal communities. The seasonal variation in the benthic fauna community was not statistically significant but variation in biological data due to differences in transect location and tidal level were significant. This spatial variation has been attributed to differences in sediment and substrate types. The physico-chemical parameters were found to correlate positively with the mud content of the sediments but were unimportant in the overall composition of the intertidal fauna. This paper complements the results reported in Al Bakriet al. (1997–Part I) in establishing a valuable benchmark for assessing environmental impacts and for developing sustainable coastal zone management in Kuwait. The integrated approach outlined here could be adopted to develop a sound basis for the protection and management of coastal environments and resources in similar areas.  相似文献

For the last three and half decades, Botswana has been widely acclaimed to be one of sub-Saharan Africa's longest and most stable liberal democracies, coupled with and sustained by a growing economy. One of the major contradictions, however, within this development scenario, has been the neglect of environmental problems in the country in general, and urban environmental issues in particular. Part of the problem fueling the misconception of environmental issues in Botswana is the state's domination of the country's environmental agenda. This is linked to the power disjunction in decision-making and policy processes between state and nonstate actors over the most appropriate course of action to tackle the problems. Without adopting appropriate analytical frameworks, it is possible that the problem of urban environmental mismanagement in Botswana will persist. This article examines some of the major urban environmental issues in Botswana from neighborhood, citywide, and urban–rural interface perspectives. Further, the elite theory of public policy is used to explain constraints on policy change in the urban environmental management arena in Botswana.  相似文献

Evaluation of Environmental Aspects Significance in ISO 14001   总被引:1,自引:0,他引:1  
The methodological framework set by standards ISO 14001 and ISO 14004 gives only general principles for environmental aspects assessment, which is regarded as one of the most critical stages of implementing environmental management system. In Estonia, about 100 organizations have been certified to the ISO 14001. Experience obtained from numerous companies has demonstrated that limited transparency and reproducibility of the assessment process serves as a common shortcoming. Despite rather complicated assessment schemes sometimes used, the evaluation procedures have been largely based on subjective judgments because of ill-defined and inadequate assessment criteria. A comparison with some similar studies in other countries indicates a general nature of observed inconsistencies. The diversity of approaches to the aspects’ assessment in concept literature and to the related problems has been discussed. The general structure of basic assessment criteria, compatible with environmental impact assessment and environmental risk analysis has also been outlined. Based on this general structure, the article presents a tiered approach to help organize the assessment in a more consistent manner.  相似文献
