A UNEP/SETAC approach towards a life cycle sustainability assessment: our contribution to Rio+20

PurposeTo contribute to the upcoming United Nations Conference on Sustainable Development (Rio+20) in 2012 by introducing a life cycle sustainability assessment (LCSA) and showing how it can play a crucial role in moving towards sustainable consumption and production. The publication, titled Towards a Life Cycle Sustainability Assessment, and published by the UNEP/SETAC Life Cycle Initiative aims to show how three life cycle techniques—(environmental) LCA, S-LCA and LCC—can be combined as part of an over-arching LCSA.MethodsThe method was demonstrated by evaluating the characteristics of each phase for each life cycle technique. In defining the goal and scope of an LCSA, for example, different aspects should be taken into account to establish the aim of the study as well as the functional unit, system boundaries, impact category and allocation. Then, the data to be collected for the life cycle sustainability inventory can be either in a unit process or on an organisational level. They can also be quantitative or qualitative. Life cycle sustainability impact assessment should consider the relevance of the impacts as well as the perspective of stakeholders. The interpretation should not add up the results, but rather evaluate them jointly. In order to clarify the approach, a case study is presented to evaluate three types of marble according to the proposed method.Results and discussionThe authors have identified that while LCSA is feasible, following areas need more development: data production and acquisition, methodological development, discussion about LCSA criteria (e.g. cutoff rules), definitions and formats of communication and dissemination of LCSA results and the expansion of research and applications combining (environmental) LCA, LCC and S-LCA. The authors also indicate that it is necessary to develop more examples and cases to improve user capacity to analyse the larger picture and therefore address the three dimensions or pillars of sustainability in a systematic way. Software and database providers are called for in order to facilitate user-friendly and accessible tools to promote LCSAs.ConclusionsThe application demonstrated that, although methodological improvements are still needed, important steps towards an overarching sustainability assessment have been accomplished. LCSA is possible and should be pursued; however, more efforts should be made to improve the technique and facilitate the studies in order to contribute to a greener economy.

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.

A method for human health impact assessment in social LCA: lessons from three case studies

PurposeImproving human health is a long-lasting endeavour of mankind. In the field of social life cycle assessment (SLCA), the importance of human health is often highlighted, and further development of impact assessment methods has been recommended. The purpose of this article is to present a method for assessing human health impacts within SLCA.MethodsBy using a systematic combining approach, knowledge and experience about assessing human health impacts were obtained from three previously conducted case studies. The first case study was about an airbag system, the second about a catalytic converter and the third about gold jewellery. The disability-adjusted life years (DALY) indicator was used for impact assessment in all three case studies.Results and discussionBoth positive and negative human health impacts associated with the products were identified and assessed in the three case studies. For the airbag system, avoided health impacts in the use phase outweighed health impacts during production. For the catalytic converter, whether health impacts avoided exceeded health impacts caused or not depended on which time perspective regarding impacts was employed. Gold jewellery does not help avoiding any health impacts but caused considerable health impacts when produced at a certain location. Based on experience from these case studies, a generic human health impact assessment method was developed, and a life cycle human health typology for products was developed based on the method. The method provides a basis for analysis and interpretation of health impacts along product life cycles, and it is therefore important to report both positive and negative health impacts separately for different actors.ConclusionsThe developed human health impact assessment method involves the assessment and comparison of both positive and negative human health impacts along product life cycles. In addition to the products assessed in the three case studies, we suggest additional products that could be particularly interesting to assess with the developed method, including medicines, seat belts, other conflict minerals, alcoholic beverages and products with a high chemical impact.

A Framework for Developing and Assessing Eco-innovations

This chapter presents a framework entitled “ECORE,” which aims to assist in developing and assessing radical eco-innovations. Our proposed framework seeks to address theoretical gaps and unresolved problems from three research fields – eco-innovation, quality management, and life cycle assessment. ECORE synthesizes ideas and concepts from these three fields into a set of key principles and practices that can further integrate sustainability into business practices. These key principles are based on the idea that stakeholder interactions should form the basis of eco-innovation, that a life cycle perspective should be adopted in the design stage of eco-innovation, and that stakeholder needs must be translated into eco-innovation characteristics throughout the design process. We illustrate our framework with a hypothetical example that focuses on reducing the environmental impacts of carbonated beverage consumption. The chapter concludes by presenting the views of practitioners that were invited to provide feedback on our proposals.

Conceptualizing Industry Efforts to Eco-innovate Among Large Swedish Companies

The term “eco-innovation” is of interest to policymakers and industrial practitioners that seek to marry environmental protection with economic development. Sweden has made some headway in that it has an international reputation for leadership on environmental issues and for creating policies that seek to boost eco-innovation in key industries. However, examining industrial efforts to eco-innovate is complicated by the fact that eco-innovation is poorly defined. The varying definitions and typologies currently in circulation pose risks to the field of eco-innovation research. In this chapter, we aim to consolidate existing conceptualizations by adapting an existing typology of eco-innovation. We then apply this typology to examine eco-innovation in large Swedish companies. The study finds that large Swedish companies focus the majority of their eco-innovative efforts on internal measures related to product and process changes. However, the companies in our sample are less adept at collaborating with suppliers, users, and other external partners that can boost eco-innovation. The study concludes by discussing the utility of our typology and by deriving recommendations for policymakers based on our findings.
