Abstract
Social and Environmental Life Cycle Assessment (SELCA) is an analytical tool for profiling and evaluating the interaction between the social and technological systems within the life cycle of given service. Environmental Life Cycle Assessment (ELCA) and Social Life Cycle Assessment (SLCA) are undertaken with their own objectives using independent methodologies. Integrating the outcomes of the two assessments provides more comprehensive and insightful descriptions of the potential impacts of a life cycle, including the key social factors through which the life cycle is sustained and modified. The SELCA approach is outlined using the examples of two fuel cycles of coal and waste in energy-generation. There are some methodological issues in combining ELCA and SLCA which we highlight in order to encourage further work on the integration of environmental and social processes in LCA.
