Challenges in Life Cycle Assessment: An Overview of Current Gaps and Research Needs

This chapter provides a comprehensive overview of current gaps of and challenges for LCA structured into inventory, impact assessment, generic and evolving aspects. A total of 34 gaps and challenges were identified. These include challenges like ‘allocation’, ‘uncertainty’ or ‘biodiversity’, as well as issues like ‘littering’, ‘animal well-being’ or ‘positive impacts’ which are not covered as often in the existing LCA literature. Each of these gaps is described by a high-level overview of the topic and its relevance to LCA, and the state of the art in terms of literature and potential solutions, if any, is presented.
