Developing sustainable products and services   总被引:4,自引:0,他引:4  
In light of increasing pressures to adopt a more sustainable approach to product design and manufacture, the requirement to develop sustainable products is one of the key challenges facing industry in the 21st century. Hence, the concept of developing sustainable products as well as services is evolving as a key element of Cleaner Production. Sustainable product development initiatives (mainly through eco-design) have been evolving for some time to support companies develop more sustainable products. Ireland has been running the highly successful Environmentally Superior Products (ESP) initiative that supports industrial companies to incorporate a more sustainable approach to the development of products and/or services. The lessons learned from the ESP and other global Sustainable Product and Service Developments in industry and research, are being used to develop a method for effective sustainable product and/or service development (SPSD) in industry. The method is designed to provide pragmatic guidance to business and industry for developing sustainable products and services as well as incorporating this approach within existing corporate strategy, cleaner production and product development systems. This method is being developed by the authors at the Environmental Policy and Management Group (EPMG), Department of Environmental Science and Technology, Imperial College London, UK in conjunction with industry and practitioners. The method provides a framework for implementing SPSD throughout the entire lifecycle of a product and/or service. It can be used to identify, assess and implement the options for optimum sustainability in the design and development of a product and/or service. This paper describes the key features of this method.  相似文献

In environmental systems analysis tools such as cost-benefit analysis (CBA), life-cycle assessment (LCA) and Environmental Management Systems (EMS), weighting is often used to aggregate results and compare different alternatives. There are several weighting sets available, but so far there is no set that consistently use monetary values based on actual or hypothetical market valuation of environmental degradation and depletion.In this paper, we develop a weighting set where the values are based on willingness-to-pay estimates for environmental quality, and market values for resource depletion. The weighting set is applied to three case studies and the outcome is compared with the outcomes from three other weighting sets, Ecotax02, Ecoindicator99 and EPS2000. We find that the different sets give different results in many cases. The reason for this is partly that they are based on different values and thus should give different results. However, the differences can also be explained by data gaps and different methodological choices. If weighting sets are used, it is also important to use several to reduce the risk of overlooking important impacts due to data gaps. It is also interesting to note that though Ecovalue08 and Ecotax02 give different absolute values, the results are very similar in relative terms. Thus the political and the individual willingness-to-pay estimates yield a similar ranking of the impacts.  相似文献

The increasing use of recycled materials in asphalt pavements calls for environmental assessment of such impacts as the energy input and CO2 footprint. Life cycle assessment (LCA) is being accepted by the road industry for such purpose. It aims to quantify and collate all the environmental impacts from the life time of the product or process. This paper reviews relevant LCA resources worldwide, identifies the knowledge gap for the road industry, and describes the development of an LCA model for pavement construction and maintenance that accommodates recycling and up-to-date research findings. Details are provided of both the methodology and data acquisition. This is followed by a discussion of the challenges of applying LCA to the pavement construction practice, and recommendations for further work. In the case study, the model is applied to an asphalt paving project at London Heathrow Terminal-5 (LHR), in which natural aggregates were replaced with waste glass, incinerator bottom ash (IBA) and recycled asphalt pavements (RAP). Production of hot mix asphalt and bitumen was found to represent the energy intensive processes. This is followed by data analysis and sensitivity check. Further development of the model includes expanding the database to accommodate the recycling and maintenance practice in the UK, and taking into account the effect that roadwork has on traffic emissions. The LCA model can be further tested and calibrated as a decision support tool for sustainable construction in the road industry.  相似文献

This article presents a conceptual exploration of the use of environmental life cycle assessment (LCA) in environmental product policy. Environmental LCA is a scientific technique for evaluating the potential environmental impacts of a product, process or activity along its physical life cycle, i.e. from raw materials extraction to the disposal of released materials to nature. The utilization of LCA in environmental policy is evaluated here with the use of concepts from the research tradition of social studies of science and technology (SST). Three different ways of using LCA are identified: a definitive approach, a conceptual approach and a facilitative approach. Examples of each approach are presented and discussed. The strengths and weaknesses of the different approaches are analyzed, leading to the tentative conclusion that LCA works better as a conceptual or facilitative instrument than as a tool for gaining definitive support for specific policies. Finally, LCA is discussed as an illustration of the problems inherent in the current cause-oriented, integrative trend in environmental policy.  相似文献

This paper explores the practical application of life cycle assessment (LCA) to product system development. While life cycle assessment methods have been studied and demonstrated extensively over the last two decades, their application to product design and development has not been critically addressed. Many organizational and operational factors limit the integration of the three LCA components (inventory analysis, impact assessment and improvement assessment) with product development. Design of the product system can be considered a synthesis of individual decisions and choices made by the design team, which ultimately shape the system's environmental profile. The environmental goal of life cycle design is to minimize the aggregate environmental impacts associated with the product system. Appropriate environmental information must be supplied to decision makers throughout each stage of the development process to achieve this goal. LCA can serve as a source of this information, but informational requirements can vary as the design moves from its conceptual phase, where many design choices are possible, to its detailed design and implementation. Streamlined approaches and other tools, such as design checklists, are essential. The practical use of this tool in product development also depends on the nature and complexity of the product system (e.g. new vs. established), the product development cycle (time-to-market constraints), availability of technical and financial resources, and the design approach (integrated vs. serial). These factors will influence the role and scope of LCA in product development. Effective communication and evaluation of environmental information and the integration of this information with cost, performance, cultural and legal criteria will also be critical to the success of design initiatives based on the life cycle framework. An overview of several of these design initiatives will be presented.  相似文献

The Expert Working Group on “Improving the Role of Government in the Promotion of Environmental Management Accounting (EMA)” was set up by the United Nations Division for Sustainable Development (UN DSD) in cooperation with a number of government agencies and non-governmental experts to promote Environmental Management Accounting (EMA) through publications, pilot projects and by establishing an international forum for discussion on the role of governments in the promotion of EMA.EMA, Environmental management accounting represents a combined approach that provides for the transition of data from financial accounting, cost accounting and mass balances to increase material efficiency, reduce environmental impacts and risks and reduce costs of environmental protection. EMA is performed by private or public corporations, but not by nations and has a financial as well as a physical component.The core focus of environmental management accounting and of the EMA UN DSD methodology is assessment of total annual environmental expenditure on emission treatment, disposal, environmental protection and management. In addition, and that is new and challenging for most companies, the material purchase value of all non-product output and its production costs are added. This total sum often provides a frightening picture of total annual costs of inefficiency and gets companies to improve their information systems and material efficiency options, which is the goal in the light of cleaner production.The first book published by the Expert Working Group, Environmental Management Accounting—Procedures and Principles (Jasch, C., United Nations, New York, 2001), defines principles and procedures for EMA, with a focus on techniques for quantifying environmental expenditures or costs, as a basis for better controlling and benchmarking purposes. The methodology excludes costs external to the company (so-called externalities, e.g. environmental and social effects that occur to the general public), but focuses on comprehensive assessment of direct annual expenditure on emission treatment, environmental protection and management as well as wasted material and energy input (efficiency losses in production). Firstly, total annual expenditure is assessed, then improvement options, savings and investment projects as well as product prices can be (re-)calculated. The method is currently applied in several case studies. The following summary provides some of the core definitions and generic assessment tables.  相似文献

Modern industrial environmental management encompasses life-cycle thinking. This entails considering not only the emissions and resource use of the company’s production processes, but also the environmental consequences of all processes related to a product’s life cycle. However, no single actor can influence the whole life cycle of a product. To be effective, analysis methods intended to support improvement actions should therefore also consider the decision makers’ power to influence.Regarding the life cycle of a product, there are at least as many perspectives on life-cycle thinking as there are actors. This paper presents an approach with which manufacturing decision makers can sharpen the focus in life-cycle assessment (LCA) from a conventional ‘products or services’ emphasis to a company’s manufacturing processes. The method has been developed by combining knowledge gained from earlier LCA studies with new empirical findings from an LCA study of an SKF manufacturing line.We demonstrate how system boundaries and functional units in an LCA can be defined when adding the perspective of a manufacturing decision maker to the product life-cycle perspective. Such analysis helps manufacturing decision makers identify improvement potentials in their spheres of influence, by focusing on the environmental consequences of energy and material losses in manufacturing rather than merely accounting for the contributions of individual stages of the life cycle to the overall environmental impact. The method identifies and directly relates the environmental consequences of emissions or raw material inputs in the product life cycle to manufacturing processes. In doing so, the holistic systems perspective in LCA is somewhat diminished in favor of the relevance of results to manufacturing decision makers.  相似文献

The COST Action 628 was established to produce first hand, industrial environmental data of textiles in Europe, as well as to suggest tools for comparisons of present technologies and practices with cleaner applications, including the economic effects. The Action network also suggested criteria for ISO (Type III) Environmental Product Declaration (EPD) standards. It was concluded that new emerging cleaner technologies are in a key position when striving towards zero emissions in textile processing. It is also important to identify the most polluting stages of textile processing, with the help of life cycle assessment methodology, in order to focus the development of new technologies correctly. LCA was used to set up criteria for an Environmental Product Declaration for textile products. Unique, first hand industrial data were collected from five European textile industries.  相似文献

The Centre for Design at RMIT University in Melbourne, Australia has developed various quantitative and qualitative tools to support decision-making by industry and government partners in product design and policy development. The aim, in general, is to support development of attractive, functional, marketable products while enhancing their environmental performance. Depending on the product, the project scope and the client, the tools that are used can be anything from a half-day char-rette, environmental checklist, to a one-year life cycle assessment (LCA).In this paper we describe our approach and the various tools that have been developed by the research team at the Centre over recent years with the use of case studies. The paper argues that it is important for tool development to be based on solid research and information, but the key to influencing product design decisions is the translation of this information into a usable format for the users.  相似文献

Companies are increasingly interested in environmental performance indicators as a means of managing the degree to which environmental goals and objectives are implemented. Many companies have publicly endorsed goals associated with sustainable development, like the International Chamber of Commerce's (ICC) principles for sustainable development. There is a need for metrics that facilitate implementation of these principles at the facility level and for research metrics that measure management improvement. An existing environmental self-assessment management tool called ESAP by the Global Environmental Management Initiative has been modified to measure a facility's response to the ICC's 16 principles of sustainability. The new tool's focus was shifted to a practical, facility based and easily applied assessment of progress towards sustainable development as represented by the ICC's 16 principles of sustainability. The new tool was called the Green Management Assessment Tool or GMAT, pilot tested and used in a research setting. Such tools have value to companies that are interested in the strategic goals of sustainable development and struggle with shifting corporate goals and objectives to manufacturing operations at the facility level.  相似文献

The purpose of this study was to characterize the situation of Portuguese Small and Medium Enterprises (SMEs) concerning the certification of their Quality Management Systems (QMS), Environmental Management Systems (EMS) and Occupational Health and Safety Management Systems (OHSMS), in their individually form, to identify benefits, drawbacks and difficulties associated with the certification process and to characterize the level of integration that has been achieved. This research was based on a survey carried out by the research team; it was administered to 46 Portuguese SMEs. Our sample comprised 20 firms (43%) from the Trade/Services activity sector, 17 (37%) from the Industrial sector, 5 (11%) from the Electricity/Telecommunications sector and 4 (9%) from the Construction area. All SMEs surveyed were certified according to the ISO 9001 (100%), a quarter of firms were certified according to the ISO 14001 (26.1%) and a few certified by OHSAS 18001 (15.2%). We undertook a multivariate cluster analysis, which enabled grouping variables into homogeneous groups or one or more common characteristics of the SMEs participating in the study. Results show that the main benefits that Portuguese SMEs have gained from the referred certifications have been, among others, an improvement of both their internal organization and external image. We also present the main difficulties in achieving certification. Overall, 7 of the Portuguese SMEs examined indicated that the main benefits of the IMS implementation management included costs reduction, increased employee training and easier compliance of legislation. The respective drawbacks and difficulties are also presented. Finally, we presented the main integrated items in the certified Portuguese SMEs we examined.  相似文献

Eco-design tools ought to be made more useful, so that they become effectively used in companies to support improvements of product systems. This article discusses the interconnections between environmental analysis and integrative cooperation in the product development processes. The study focuses on two different assessment tools, life cycle assessment (LCA) and environmental effect analysis (EEA), in three different combined uses. The discussion of the Eco-design methods focuses on integration in product development processes considering the relation to a product competitiveness perspective. The interviews indicate that the interconnection of methods is important as a key to real transformation of design practices.  相似文献

Life Cycle Assessment (LCA) is a well-known tool for analyzing environmental impacts on a wide perspective with reference to a product system and the related environmental and economic impacts. The need for a novel approach that complements environmental and financial considerations is addressed in this study with the introduction of a new graphical representation: the Environmental Performance Strategy Map. This graphical map allows one to combine the main environmental indicators (footprints) with the additional dimension of cost. The paper defines the Sustainable Environmental Performance Indicator as a single measure for sustainability of a given option. Comparison of different options for strategic decision-making purposes can be enhanced and facilitated by the use of this indicator.  相似文献

This paper examines a high profile and often provocative segment of the financial industry: that of Ethical or Socially Responsible Investment. By offering an ethical or sustainable product which has the potential to influence so many stakeholders—the financial industry is in a unique position to guide change towards corporate sustainability. However, what message is ethical investment really giving to companies and the financial industry? Are ethical investors and their rating agencies capable of effectively influencing corporations towards more sustainable patterns of production and consumption; and are their approaches consistent with the principles of Cleaner Production? This paper first gives an overview some of the definitions ‘ethical investment’ and the scale of activities under this umbrella term. Then the actual screening methods and their application is examined. A typology of the different ethical mutual funds is given, and two cases of ethical funds are described (Robur’s Environmental Fund, and Sustainable Asset Management’s sustainability rating tool). Each are analysed in terms of their potential to either reveal or conceal cleaner production innovations by the firms they assess. In order to ascertain where Ethical Investment might lead companies, the effects of ethical investment on companies—and back on the asset management companies themselves is explored. A reflexive model of corporate and finance sector learning based on the ethical screens is proposed.  相似文献

The shift in policy towards prevention and towards making producers responsible for the pollution they cause has lead corporations to limit environmental liabilities through the improvement of environmental performance. The implementation of an Environmental Management System integrates the precautionary and polluter pays principles into a firm's operations and demonstrates commitment to sustainable development. This research aims at assessing the factors influencing the implementation of ISO 14001 Environmental Management System in developing countries taking the Food Industry in Lebanon as a case example. For this purpose, primary data were collected using a field survey questionnaire that was administered to a representative sample of facilities. The results revealed that the food industry is generally more concerned with safety and quality issues rather than environmental issues. Following international food sector trend, improving environmental performance and enhancing company image are the most salient drivers to adopt ISO 14001. The lack of government support and stakeholder demand as well as the fact that ISO 14001 is not a legal requirement constitute the most salient factors hindering the adoption of the standard. Economical and organizational factors are the most significant incentives required to motivate the food industry to adopt ISO 14001. The industry is less likely to voluntarily consider adopting ISO 14001 before acquiring a quality management certification or until ISO 14001 certification gain more recognition in the international food sector. The study defines the foundations for developing strategies, policy reforms and incentive schemes to reduce the barriers of implementing ISO 14001.  相似文献
