A central asset of eco-efficiency analysis is that it does not depend on a specific evaluation of environmental impacts against economic effects. Several evaluation methods may be used, including those based on willingness-to-pay, panel procedures, and public statements on policy goals. This volume covers all aspects of eco-efficiency analysis and offers a global perspective on the subject.
Eco-efficiency is an instrument for sustainability analysis, indicating an empirical relation in economic activities between environmental cost or value and environmental impact. This empirical relation can be matched against normative considerations as to how much environmental quality or improvement society would like to offer in exchange for economic welfare, or what the trade-off between the economy and the environment should be if society is to realize a certain level of environmental quality. Its relevance lies in the fact that relations between economy and environment are not self-evident, not at a micro level and not at the macro level resulting from micro-level decisions for society as a whole. Clarifying the why and what of eco-efficiency is a first step toward decision support on these two aspects of sustainability. With the main analytic framework established, filling in the actual economic and environmental relations requires further choices in modeling. Also, the integration of different environmental effects into a single score requires a clear definition of approach, because several partly overlapping methods exist. Some scaling problems accompany the specification of numerator and denominator, which need a solution and some standardization before eco-efficiency analysis can become more widely used. With a method established, the final decision is how to embed it in practical decision making. In getting the details of eco-efficiency better specified, its strengths, but also its weaknesses and limitations, need to be indicated more clearly.
Assessing and Measuring Environmental Impact and Sustainability answers the question “what are the available methodologies to assess the environmental sustainability of a product, system or process?” Multiple well-known authors share their expertise in order to give a broad perspective of this issue from a chemical and environmental engineering perspective. This mathematical, quantitative book includes many case studies to assist with the practical application of environmental and sustainability methods. Readers learn how to efficiently assess and use these methods. This book summarizes all relevant environmental methodologies to assess the sustainability of a product and tools, in order to develop more green products or processes. With life cycle assessment as its main methodology, this book speaks to engineers interested in environmental impact and sustainability. Helps engineers to assess, evaluate, and measure sustainability in industry Provides workable approaches to environmental and sustainability assessment Readers learn tools to assess the sustainability of a process or product and to design it in an environmentally friendly way
This thought-provoking and colorful book cuts through the fog of vision and advocacy by comparing and applying new quantitative tools of both environmental and ecological economics. Environmental accounts and empirical analyses provide operational concepts and measures of the sustainability of economic performance and growth. The text raises doubts, however, about the measurability of sustainable development. Further reading sections are provided at the end of each chapter.
Eco-efficiency at the product level is defined as product value per unit of environmental impact. In this paper we present a method for quantifying the eco-efficiency using quality function deployment (QFD) and life-cycle impact assessment (LCIA). These well-known tools are widely used in the manufacturing industry. QFD, which is one of the methods used in product development based on consumer preferences, is introduced to calculate the product value. An index of the product value is calculated as the weighted average of improvement rates of quality characteristics. The importance of customer requirements, derived from the QFD matrix, is applied. Environmental impacts throughout a product life cycle are calculated based on an LCIA method widely used in Japan. By applying the LCIA method of endpoint type, the endpoint damage caused by various life-cycle inventories is calculated. Willingness to pay is applied to integrate it into a single index. Eco-design support tools, namely, the life-cycle planning (LCP) tool and the life-cycle assessment (LCA) tool, have already been developed. Using these tools, data required for calculation of the eco-efficiency of products can be collected. The product value is calculated based on QFD data stored in the LCP tool and the environmental impact is calculated using the LCA tool. Case studies of eco-efficiency are adopted and the adequacy of this method is clarified. Several advantages of this method are characterized.
Prefaced by Björn Stigson, President of the World Business Council for Sustainable Development, this book is one of the few that treats this topic by putting representatives of industry at centre stage. The book systematically addresses the drivers, the tools, and sector-specific elements that play a role in this process. The five chapters in Part I are devoted to a general introduction to eco-efficiency and the related challenges to industry in its implementation. Part II contains 23 case studies, almost all written by industrial experts who tell how they deal with the challenge: what the motivators are, what tools can be used and how they can be implemented, and what are the specific elements in sectors like building, electronics and packaging. These contributions come from multinationals like Unilever, Procter & Gamble, Akzo Nobel, Philips and Ciba-Geigy, as well as small and medium sized enterprises from such sectors as the building and furniture trades.
