Life Cycle Analysis Flashcards
What are the 4 principles of a LCA?
Goal & scope, life cycle inventory, impact assessment, interpretation.
Which LCA principle/step sets the system boundaries?
Goal & scope.
Which LCA principle/step establishes the motivation for the study?
Goal & scope.
Which LCA principle/step establishes the intended use of results?
Goal & scope.
Which LCA principle/step establishes the intended use of results?
Goal & scope.
Which LCA principle/step establishes the resources available to conduct the study?
Goal & scope.
Which LCA principle/step establishes the perspective of the analysis?
Goal & scope.
Which LCA principle/step lists and quantifies the inputs and outputs of the processes at each stage in one life cycle?
Life cycle inventory.
What are the 4 stages to consider in the life cycle inventory principle/step?
Raw materials acquisition, manufacturing, product use, and product disposal.
Which stage of the life cycle inventory principle/step usually considers product packaging and transportation to the consumer?
Manufacturing.
Which stage of the life cycle inventory principle/step usually considers maintenance and repair of the product?
Product use, as maintenance/repair would occur during its useful life.
Throughout all four stages, the inventory analysis quantifies the amount of each material used as input at each stage. Besides material, what other input is quantified?
The amount of energy.
The impact assessment principle/step uniquely determines the impacts of each input identified in the life cycle inventory step.
False - impacts of outputs are also assessed.
Is relating metrics to objectives a part of data interpretation or improvement analysis?
Data interpretation.
Is quantifying human and ecological effects a part of data interpretation or improvement analysis?
Data interpretation.
