Abstract

The use of life-cycle assessment (LCA) to understand the embodied energy, environmentalimpacts, and potential energy-savings of manufactured products has become more widespreadamong researchers in recent years. This paper reviews recent LCA studies in the cement industryin China and in other countries and provides an assessment of the methodology used by theresearchers compared to ISO LCA standards (ISO 14040:2006, ISO 14044:2006, and ISO/TR14048:2002). We evaluate whether the authors provide information on the intended application,targeted audience, functional unit, system boundary, data sources, data quality assessment, datadisaggregation and other elements, and draw conclusions regarding the level of adherence to ISOstandards for the papers reviewed. We found that China researchers have gained muchexperience during last decade, but still have room for improvement in establishing boundaries,assessing data quality, identifying data sources, and explaining limitations. The paper concludeswith a discussion of directions for future LCA research in China.
