In the modern economy, international value chains--production, use, and disposal of goods--have global environmental impacts. Life Cycle Assessment (LCA) aims to track these impacts and assess them from a systems perspective, identifying strategies for improvement without burden shifting. We review recent developments in LCA, including existing and emerging applications aimed at supporting environmentally informed decisions in policy-making, product development and procurement, and consumer choices. LCA constitutes a viable screening tool that can pinpoint environmental hotspots in complex value chains, but we also caution that completeness in scope comes at the price of simplifications and uncertainties. Future advances of LCA in enhancing regional detail and accuracy as well as broadening the assessment to economic and social aspects will make it more relevant for producers and consumers alike.

Emerging approaches, challenges and opportunities in life cycle assessment

Corporate sustainability performance measurement systems (SPMS) have been the subject of a growing amount of research. However, there are many challenges and opportunities associated with the design, implementation, use, and evolution of these systems that have yet to be addressed. The purpose of this article is to identify future directions for research in the design, implementation, use, and evolution of corporate SPMS. A concise review of key literature published between 2000 and 2010 is presented. The literature review focuses on research conducted at the both the individual corporation- and sector-levels. The review of published literature provides a basis for the identification of a structured set of 65 key research questions to guide future work. The research questions will be of interest to both practitioners and researchers in corporate sustainability performance measurement.

Bridging the gap between LCA, LCC and CBA as sustainability assessment tools

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

Environmental life-cycle costing: a code of practice

Past life cycle assessments (LCA) of sugarcane (Saccharum officinarum) production have commonly been based on limited datasets, and variability has not been well described. In this work, Australian sugarcane production was assessed more comprehensively in order to generate a robust set of LCA results for use in subsequent assessments of sugarcane products and also to investigate: (1) variability due to regional differences, (2) factors influencing variability, and (3) significance of the impacts. An average scenario for Australian sugarcane production was modeled based on data for the state of Queensland (98% of Australian production). Life cycle impact assessment (LCIA) results were generated using Impact 2002+, modified to be more representative of Australian conditions, and with the inclusion of water use and land use indicators. A Monte Carlo uncertainty analysis, using minimum and maximum values for production data, was undertaken to evaluate variability. Different regional production practices were also modeled to identify factors that influence variability. Normalization aimed to show the significance of total Australian sugarcane production relative to total Australian impacts. Considerable variability was found in the LCIA results, with the key variables being yield, N use efficiency, the susceptibility of soils to N leakage, irrigation (water and energy intensity), and pre-harvest burning. N leakage was found to be an important issue that influences a range of impact categories. When normalized against total national impacts, water use and land use appear to be the most significant impacts (based on simple indicators of consumption), followed by eutrophication potential, acidification potential, and respiratory impacts, whereas non-renewable energy input and global warming are less significant. The results suggest that toxicity impacts are insignificant; however, this may not be supported by other observations that link pesticide loss from sugarcane to toxicity concerns in receiving waters and is a subject for further research. The potential for significant variability in the impacts from sugarcane growing suggests a need for LCAs of sugarcane systems to consider ranges for key variables. The key variables and significant impacts identified in this work can guide data collection priorities for future assessment of sugarcane and possibly other Australian cropping systems. To further develop LCA as a useful predictive tool for Australian agricultural systems, further development and testing of impact assessment models for eutrophication, toxicity, and land and water resource depletion appropriate for Australia and its subregions will be required.

Life cycle assessment of Australian sugarcane production with a focus on sugarcane growing

Purpose
This work generates attributional life cycle assessment (LCA) results for products produced from Australian sugarcane—raw sugar, molasses, electricity (from bagasse combustion), and ethanol (from molasses). It focuses on cane processing in sugar mills and is a companion to the work presented in (Renouf et al. 2010), where the focus is on cane growing. This work also examines the preferred approach for assigning impacts to the multiple products from cane processing, and the influence that variability in cane growing has on the results.

Bio-production from Australian sugarcane: an environmental investigation of product diversification in an agro-industry

This manual has been developed to help the Australian dairy processing industry increase its competitiveness through increased awareness and uptake of eco-efficiency The manual seeks to consolidate and build on existing knowledge, accumulated through projects and initiatives that the industry has previously undertaken to improve its use of raw materials and resources and reduce the generation of wastes Where there is an existing comprehensive report or publication, the manual refers to this for further information Eco-efficiency is about improving environmental performance to become more efficient and profitable It is about producing more with less It involves applying strategies that will not only ensure efficient use of resources and reduction in waste, but will also reduce costs This chapter outlines the environmental challenges faced by Australian dairy processors The manual explores opportunities for reducing environmental impacts in relation to water, energy, product yield, solid and liquid waste reduction and chemical use
