This article provides guidelines for conducting consequential life cycle assessment (LCA) studies. It presents the main features of two alternative approaches used in LCA-attributional and consequential-and describes how consequential LCA can be performed consistently and appropriately, with an example provided to guide practitioners. It is argued that, despite its limitations, consequential LCA is a robust approach for estimating important indirect effects of products.
