Popis: 1 IntroductionSociety of Environmental Toxicology and Chemistry(SETAC) has published a code of practice for environmentallife-cycle costing (LCC), which provides a framework forevaluating decisions with consistent, but flexible systemsboundaries as a component of product sustainabilityassessments (Swarr et al. 2011). The code of practicebuilds on an earlier monograph that summarized 3 years ofeffort by the SETAC-Europe Working Group on Life-Cycle Costing (Hunkeler et al.2008).Thecodeofpracticeis grounded in a conceptual framework for life-cyclesustainability assessment (LCSA) of products that usesdistinct analyses for each of the three pillars of sustainability,environment, economy, and social equity.LCSA ¼ LCAþ LCCþ SLCA ð1ÞLife-cycle assessment (LCA) is the only pillar that has beenstandardized to date (ISO 2006a, b). UNEP (2009)haspublished guidelines for social LCAs and is currentlydeveloping methodological sheets for impact subcategories.The code of practice reviews historical development of life-cycle methods, outlines the technical requirements and guide-lines for LCC, and illustrates various methodological choiceswith a detailed case study. The objective of the code of practiceis to provide readers with a solid understanding of how to applyLCC in parallel with LCA to stimulate additional case studiesand peer-reviewed research to further refine the methodology.The ultimate goal is to build consensus for an internationalstandard that parallels the ISO 14040 standard for LCA.2 DiscussionLCC predates LCA, and distinct and different conceptualfoundations and methodological approaches can betraced to its developmental roots in systems engineering(Blanchard 1978). There has been limited integration ofthese methods, although the value of LCC for sustainabilityassessmentshasbeenrecognized(Norris2001;Hunkelerand
