Life cycle impact assessment (LCIA) is among the last steps of LCA. The purpose of a LCIA “is to provide additional information to assess life cycle inventory (LCI) results and help users better understand the environmental significance of natural resource use and environmental releases”.

What is LCI in life cycle?
Life cycle inventory (LCI) is the methodology step that involves creating an inventory of input and output flows for a product system. Such flows include inputs of water, energy, and raw materials, and releases to air, land, and water. The inventory can be based on literature analysis or on process simulation.
What are the advantages disadvantages and limitations of LCA?
LCA allows decision makers to compare two products and to select the product that has the lowest impact on the environment. As LCA considers the full life cycle and it avoids burden shifting: it prevents reducing the environmental impact in one stage while increasing the impact at other stages of the life cycle.
Why is life cycle impact assessment important?
Life cycle impact assessment (LCIA) is the method for converting inventory data from a life cycle assessment into a set of potential impacts. This enables practitioners and decision makers to better understand the damage caused by resource use and emissions.
Why is life cycle inventory important?
Without a life-cycle inventory, no basis exists to evaluate comparative environmental impacts or potential improvements. The level of accuracy and detail of the data collected is reflected throughout the remainder of the LCA process.
