Which of the following is not considered a type of LCA?

Holistic LCA is not considered a separate type of Life Cycle Assessment (LCA). Instead, it's often understood as an approach that combines various aspects of other LCA types. The overall goal of an LCA is to assess the environmental impacts associated with all stages of a product's life cycle, from raw material extraction through to disposal. Therefore, while holistic approaches play an important role in analyses, they do not categorize as a distinct type of LCA on their own.

On the other hand, other types of LCA, such as Bottom-up, EIO-LCA (Economic Input-Output LCA), and Streamlined LCA, each have specific methodologies and applications that set them apart. Bottom-up LCA typically involves detailed and specific data collection for individual products. EIO-LCA utilizes economic data to evaluate the environmental impacts of different sectors and industries, facilitating a broader overview. Streamlined LCA, as the name suggests, employs simplified methods to provide faster assessments, often for preliminary evaluations. Each of these methodologies highlights different facets of evaluating a product's life cycle, distinguishing them from the concept of holistic LCA.
