Life-cycle assessment (LCA or life cycle analysis) is a technique used to assess potential environmental impacts of a product at different stages of its life. This technique takes a "cradle-to-grave" or a "cradle-to-cradle" approach and looks at environmental impacts that occur throughout the lifetime of a product from raw material extraction, manufacturing and processing, distribution, use ...
Life cycle assessment (LCA) is sometimes referred to synonymously as life cycle analysis in the scholarly and agency report literatures. [7] [1] [8] Also, due to the general nature of an LCA study of examining the life cycle impacts from raw material extraction (cradle) through disposal (grave), it is sometimes referred to as "cradle-to-grave analysis".
A life cycle analysis is often conducted when assessing the sustainability of a product or prototype. [38] The decision to choose materials is heavily weighted on its longevity, renewability, and efficiency. These factors ensure that researchers are conscious of community values that align with positive environmental, social, and economic ...
Life-cycle assessment is a "composite measure of sustainability." [19] It analyses the environmental performance of products and services through all phases of their life cycle: extracting and processing raw materials; manufacturing, transportation and distribution; use, re-use, maintenance; recycling, and final disposal.
This can be accomplished by conducting life-cycle assessments or surveys to help determine their sustainability practices. Another strategy is to award suppliers for their improvement on their sustainability performance, for instance, by developing new materials sourced from waste or by making operations more energy efficient .
The development process conducted a rigorous technical analysis by deploying a rule-based process of analysis and feedback based on technology developments and market feedback. Stage (I) of the development process involved the examination of more than 140 building rating systems, tools, guidelines and standards around the globe.
Life-cycle cost analysis (LCCA) is an economic analysis tool to determine the most cost-effective option to purchase, run, sustain or dispose of an object or process. The method is popular in helping managers determine economic sustainability by figuring out the life cycle of a product or process.
Life cycle engineering is defined in the CIRP Encyclopedia of Production Engineering as: "the engineering activities which include the application of technological and scientific principles to manufacturing products with the goal of protecting the environment, conserving resources, encouraging economic progress, keeping in mind social concerns, and the need for sustainability, while optimizing ...
