What is a product life cycle analysis (LCA)?
Mar 18, 2021 · A Life Cycle Analysis (LCA), or also known as a Life Cycle Assessment, is a methodology used to evaluate the impact a product, service, or activity has on the environment. An LCA can be used to determine the sustainability of a product by considering its impact at each stage of the life cycle.
Life cycle analysis (LCA) has been defined by the EPA as a way to “evaluate the environmental effects associated with any given industrial activity from the initial gathering of raw materials from the earth until the point at which all residuals are returned to the earth” or “cradle-to-grave.”

This article explains the definition, process and impact categories of a Life Cycle Assessment (LCA) including eutrophication and ozone depletion. It also mentions the sources of primary and secondary data, quality assurance checks for collected data, and summarizes the overall approach for an LCA study with 30 years of experience from Sphera Susta...
A systematic analysis of the potential environmental impacts of products or services during their entire life cycle. Includes upstream and downstream processes associated with production, use phase, and disposal. ISO 14040 and 14044 provide guidelines for conducting a Life Cycle Assessment.
Covers all relevant inputs from environment (e.g., ores, crude oil) as well as emissions into air, water and soil (e.g., carbon dioxide). Eutrophication covers impacts of high levels of nitrogen & phosphorus; ozone depletion measures air emissions that contribute to stratospheric ozone layer depletion leading to higher UVB ultraviolet rays reaching...
The level of detail depends on data availability, time available for data collection, relevance of the data point & scope of the LCA; sources include primary (bills/recipes), secondary (LCA databases), technical literature etc.; collected data needs quality assurance checks for completeness & consistency via mass balance etc..

Life Cycle Analysis (LCA) is a general term that has many names such as life cycle assessment and cradle-to-grave analysis. The Life Cycle Analysis methodology evaluates the energy requirements, environmental impacts, and life-cycle costs of a process or product by quantifying all the material inputs and outputs and their respective energy and ...
