Mapping the green product development field: engineering, policy and business perspectives

The literature study on which we report here is based on a cross-disciplinary database containing around 650 articles, taken from the engineering, management, and policy studies disciplines. We report on this literature using a model distinguishing between the product development processes as such, and different contexts, such as the company as a whole, the product chain and society. In addition, a distinction is made between empirically informed research and more conceptual work. Confronting the references in the database with this model, we identify several white spots on the map of research on environmental product development. These seem to be the understanding of the use and role of tools on a micro level (within companies), and an understanding of how this micro-level interacts with the macro level (between companies and in public policies). Also, a strategic orientation on the product development process within companies is underdeveloped. We argue that, in order to make an environmental optimisation of resource use and a minimisation of emissions, a systems perspective is necessary, both in research and practice.

Choice of system boundaries in life cycle assessment

System boundaries in life cycle assessments (LCA) must be specified in several dimensions: boundaries between the technological system and nature, delimitations of the geographical area and time horizon considered, boundaries between production and production of capital goods and boundaries between the life cycle of the product studied and related life cycles of other products. Principles for choice of system boundaries are discussed, especially concerning the last dimension. Three methods for defining the contents of the analysed system in this respect are described: process tree, technological whole system and socio-economic whole system. The methods are described in the applications multi-output processes and cascade recycling, and examples are discussed. It is concluded that system boundaries must be relevant in relation to the purpose of an LCA, that processes outside the process tree in many cases have more influence on the result than details within the process tree, and that the different methods need to be further compared in practice and evaluated with respect to both relevance, feasibility and uncertainty.

Life cycle assessment: A comparison of three methods for impact analysis and evaluation

For the evaluation of data resulting from the inventory stage of a life cycle assessment, two sets of environmental indices based on Swedish data have been calculated according to the ‘ecological scarcity method’ and the ‘environmental theme method’. These are compared with indices from the method for ‘environmental priority strategies in product design’. The relative importance of CO2, SO2 and NOx in the three evaluation methods, expressed as index ratios CO2:SO2:NOx′ was calculated to be 1:200:250, 1:220:350 and 1:150:6100, respectively. Additional index comparisons are presented. Differences in the results from the three methods depend on effects considered, how the algorithms are constructed, and background data. The discussion focuses on similarities and differences in mathematical expressions and on the evaluation of certain substances.

6th SETAC-Europe Meeting: LCA — Selected Papers

A study of industry’s use of LCA has been performed as a special analysis of the Business Environmental Barometer (B.E.B.). The B.E.B. is an international questionnaire survey on industry’s environmental management practices (LCA included), repeated every two years. The first round in 1993 included the Nordic countries. The 1997 round will include eight European countries. This analysis intends to describe industry’s LCA use as such (e.g. active industrial sectors, applications, changes over time) and differences between companies working with LCA and those not working with LCA. The survey indicates that industry is in the process of internalising LCA knowledge, although most companies are still in the learning phase. LCA companies have more developed environmental management systems than non-LCA companies. A company’s LCA use seems to be a competitor-driven activity, judging from LCA distribution among industrial sectors.A study of industry’s use of LCA has been performed as a special analysis of the Business Environmental Barometer (B.E.B.).

Environmental assessment of organising: towards a framework for the study of organisational influence on environmental performance

The paper discusses a new perspective on industryOs environmental performance and presents the concept and field of Environmental Assessment of Organising. EAO builds on the notion that different ways of managing industrial production lead to different environmental performance. To understand how industrial organising influences environmental performance it is necessary to take ordinary physical flow modelling of technical systems, such as life cycle assessment, a step further by embedding these in an organisational context. Such an understanding could provide new knowledge for environmentally OsmarterO management. The concept of EAO aims towards a theoretical framework that bridges environmental management, organisational theory and environmental systems analysis. Its presentation here is grounded in a literature review on works related to industrial environmental performance. Two studies testing the practical application of EAO are briefly presented and discussed. These have contributed to the presented basic methodology and rudimentary research programme for EAO studies.

On the scientific justification of the use of working hours, child labour and property rights in social life cycle assessment: three topical reviews

PurposeWorking hours, child labour and property rights have been suggested as topics to assess in social life cycle assessment (SLCA). The purpose of this study is to investigate the scientific justification of the current use of these topics. The long-term aim is to contribute to the future development of SLCA.MethodsA literature review was conducted for each of the three topics. One thousand scientific articles were analysed for each topic, and relevant articles were selected. The articles were analysed based on whether the topics facilitated or obstructed beneficial social values, and whether they facilitated or obstructed adverse social values.Results and discussionThe results show that the three topics both facilitate and obstruct beneficial social values. They also show that the topics both facilitate and obstruct adverse social values. Considering the complex and ambiguous nature of these topics reported in the scientific literature, the current use of these topics in the SLCA literature is found not to be completely scientifically justified.ConclusionsBased on this study, the current use of working hours, child labour and property rights in SLCA studies should be questioned. We suggest that the fields of social science and economics may be fruitfully considered when seeking scientific justification for topics to assess in SLCA.

Introduction and organisation of LCA activities in industry

Explorations of the LCA practice have been less numerous compared to the conceptual descriptions of LCA. To counter this imbalance, studies of LCA projects conducted in Swedish industry were carried out. One of them is in a chemical company, the other in an electronics company. The studied LCA projects represent early attempts, but not first attempts, at LCA within these two companies. The two studied cases are contrasted with each other and aspects important for the implementation of LCA are identified. Among other things, the presence of an LCA entrepreneur seems to be important for LCA implementation. The argumentation for the usefulness of LCA needs to be situationally adapted to each organisation. Strategies of the LCA entrepreneur are described.

The Usefulness of an Actor’s Perspective in LCA

This paper is an argumentation for adding an actor’s perspective to lifecycle assessment (LCA). The need for this perspective stems from a criticism about the usefulness of LCA interpretation methods comparing the relative contribution of life-cycle phases of a product. Our argumentation is based on four previously published studies providing practical examples of how value chain actors’ influence may be considered in an LCA and the benefit of doing so. Manufacturing sector examples show how one companys influence can be illustrated in results and how it may relate all relevant emissions to its own processes. The food sector study shows how to assess several value chain actors’ individual improvement potential. The final example, taken from building sector, explore how to consider the fact that actors in one part of the value chain can influence other actors to improve.

Organizing life cycle management in practice: challenges of a multinational manufacturing corporation

PurposeThe environmental life cycle management (LCM) literature proposes many factors considered critical in order to successfully conduct LCM. This study contrasts these vague and general factors proposed as critical to LCM in existing literature, with detailed accounts of LCM in practice.MethodsA literature review of three related research fields, i.e., LCM, life cycle thinking, and sustainable supply chain management, is contrasted with a study of how LCM is enacted in practice in a large multinational manufacturing company recognized for its LCM work. A qualitative study, with mainly a managerial focus, is conducted based on interviews, workshops, part-time observations, and document studies.Results and discussionThe literature review demonstrates that the three related research fields provide different accounts of LCM: all apply a holistic environmental perspective, but with different emphases and using largely different research methods. The empirical study shows that integration was a common topic at the studied company and that solutions were often sought in tools and processes. Middle management support proved important, and challenging, in these integration efforts. Challenges identified also included further integrating LCM into departments such as purchasing and sales.ConclusionsThe constant focus on integration at the studied company implies that LCM work is an ongoing effort. Several integration paths are identified: (1) inclusion of sustainability aspects in tools and processes, (2) finding ways to work around certain organizational levels, and (3) using networks and social interaction to create commitment and integration. Although the concept of LCM implies a holistic approach, LCM in practice reveals a lack of a comprehensive overview of LCM-related initiatives and of involved sustainability practitioners within the studied organization.

LCA as an element in environmental management systems—comparison of conditions in selected organisations in Poland, Sweden and Germany

PurposeIn this two-part paper (Background and Initial Assumptions (Part 1) and Results of Survey Research (Part 2)), we present surveys whose main objective is to determine, whether and to what extent the life cycle assessment (LCA) technique is used for the identification and assessment of environmental aspects in environmental management systems (EMS) and whether there are any differences in this respect between the companies and countries analysed.MethodsThe survey research was carried out using the computer assisted self-administered interviewing (CASI) method among selected Polish, German and Swedish organisations which implement EMS in accordance with the requirements of ISO 14001 and/or the EMAS regulation.ResultsThe organisations investigated, regardless of their country, are dominated by qualitative and semi-quantitative techniques of assessment and identification of environmental aspects. LCA was used sporadically, although some differences can be observed between the countries analysed.ConclusionsThe environmental managers accustomed to traditional qualitative and semi-quantitative solutions, have not been given preparation to enable them to understand and adopt the different approaches such as LCA. On the other hand, representatives of the organisations investigated declared that they were ready to accept an even longer timescale for the identification and assessment processes relating to environmental aspects, which represents a potential opportunity for LCA. The more precise understanding and definition of environmental problems that are precisely defined in LCA would represent a novelty for environmental managers. In practice, environmental problems are defined in a general sense and rather ambiguously, as this level of detail is sufficient in the context of qualitative and semi-quantitative techniques commonly used for the identification and assessment of environmental aspects.
