“…The LCA methodology is described by four phases: (1) goal and scope definitions; (2) inventory analysis; (3) impact assessment; and (4) interpretation (Curran, 2006;Georgakellos, 2006). The foundation of a product's LCA is the inventory component where energy, raw materials and environmental releases are measured (Hassan, 2003;Ison and Miller, 2003). Specifically, the task in the inventory stage is to trace (ideally) all inputs to and outputs from every stage in the life cycle back to the associated terminal inputs to and outputs from nature (the environment).…”

The present work aims to examine the strategic decision of future electricity generation mix considering, together with all other factors, the effect of the external cost associated with the available power generation technology options, not only during their operation but also during their whole life-cycle. The analysis has been performed by integrating the Life Cycle Assessment concept into a linear programming model for the yearly decisions on which option should be used to minimise the electricity generation cost. The model has been applied for the case of Greece for the years 2012-2050 and has led to several interesting results. Firstly, most of the new generating capacity should be renewable (mostly biomass and wind), while natural gas is usually the only conventional fuel technology chosen. If externalities are considered, wind energy increases its share and hydro-power replaces significant amounts of biomass-generated energy. Furthermore, a sensitivity analysis has been performed. One of the most important findings is that natural gas increases its contribution when externalities are increased. Summing-up, external cost has been found to be a significant percentage of the total electricity generation cost for some energy sources, therefore significantly changing the ranking order of cost-competitiveness for the energy sources examined.

This paper presents a novel framework to aid assessment and selection in certain technology investments projects. Since most of the methods available for this purpose consider factors that seem to focus almost exclusively on what creates most net value to the buyer of a technology system, ignoring the external costs associated with this system, the technique proposed here has been developed in order to provide a tool for the integration of the environmental externalities in the assessment and selection process. This tool uses the findings of Life Cycle Assessments (LCAs) and especially the outcomes of the LCA Polygon approach in order to consider for each possible alternative its environmental performance together with any economic aspects, and to result into a single "score", i.e. the relative external cost. This value could be used as the exclusive basis for the comparative appraisal of the candidates, or it could be easily integrated in most of the existing decision methods. A relevant case study is also included in the paper to illustrate the proposed framework. It is about the assessment of an investment concerning five different vehicle technologies. The result of this application can be easily incorporated in almost any common decision-making model, which intends to take into consideration the externalities of its choice.

AbstractPurpose -Recycling of non-renewable resources serves both in reducing the consumption of virgin supplies and the discharge of associated residuals back into the natural environment. On the other hand, recycling has been criticized because of its environmental impacts. The aim of the present paper is to identify and quantify the environmental effect of recycling of a glass bottle. Design/methodology/approach -For this purpose, the life cycle assessment polygon framework is being used. This framework has been developed for evaluating the results of a life cycle inventory analysis using critical volume aggregation and polygon-based interpretation. Findings -Recycling strategies can, in most cases, reduce the total environmental burden of the glass container examined. However, this reduction may considerably vary in relation to each "ecological parameter" (consumption of energy, consumption of water, air emissions, waterborne waste and solid waste), depending mainly on the "recycling mix" (the percentage of recycled material used in production and the percentage of product waste that goes for recycling).
