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 thinking can be applied to the five stages of the waste management hierarchy. For example, life-cycle analysis has shown that it is often better for the environment to replace an old washing machine, despite the waste generated, than to continue to use an older machine which is less energy-efficient. This is because a washing machine ...
A life cycle analysis can serve as a tool when determining the environmental impact of a product or process. Proper LCAs can help a designer compare several different products according to several categories, such as energy use, toxicity, acidification, CO 2 emissions, ozone depletion, resource depletion and many others. By comparing different ...
Life Cycle Analysis (LCA) is a tool used to understand the how a product impacts the environment at each stage of its life cycle, from raw input to the end of the products' life cycle. Life Cycle Cost (LCC) is an economic metric that "identifies the minimum cost for each life cycle stage which would be presented in the aspects of material ...
The actions that you can do within the strategy to reach success within the system e.g. Raise awareness on specific sustainability topics, education programs on what sustainability is and how it could be approached, selecting different suppliers based on sustainability criteria, designing or implementing policies, analyze the life cycle of a ...
Combining such data sets can enable accounting for long chains (for example, building an automobile requires energy, but producing energy requires vehicles, and building those vehicles requires energy, etc.), which somewhat alleviates the scoping problem of traditional life-cycle assessments. EIO-LCA analysis traces out the various economic ...
