Abstract

Life Cycle Assessment (LCA) is an internationally recognised approach for evaluating the environmental impacts of products and services. In this paper, the potential issues in the development of a consistent and comprehensive life cycle inventory (LCI) data are illustrated in the context of Australian cotton industry. These include diversity and variable nature of farming practices, and the inherent complexities such as the inter-linkages between co-products. For the implementation of LCI, the choices of functional unit and system boundary, definition of regional sub-sectors, methods of energy assessments, and rules of allocations of inputs and emissions are discussed. It is shown that for cotton production, the contribution of on-farm indirect 'chemical' inputs is particularly important, accounting for up to 50–80% of the total energy input in the life cycle. The need for quantified trade off analysis between alternative systems in the LCA context is also emphasized.
