Considerations and a report on the state of practice

Life Cycle Assessment (LCA) is an analytical tool to evaluate the environmental consequences of products and their production systems. A great deal of effort has been devoted to developing methodology and guidelines for conducting LCAs. However, many companies are devising shortcuts to the full LCA model. We conducted discussions with twenty-one LCA practitioners and researchers to investigate techniques being used to simplify or streamline the LCA methodology. We found a wide variety of approaches being used to accomplish the streamlining from convening informal in-house expert panels to identify life cycle issues to developing and applying formal, structured tools.
