Definition of life cycle assessment : Comprehensive ecological assessment that identifies the energy, material, and waste flows of a product, and their impact on the environment.
LCA is a technique to . This cradle to grave evaluation begins with the design of. Improvement assessment. The process is naturally iterative as the quality and completeness of information and its plausibility is constantly being tested. LCI is the life cycle inventory, which is the data collection portion of LCA.
Quantitative environmental life cycle assessment of products can be a useful tool in product-oriented environmental management. With this methodology the environmental impacts of the product during its entire life cycle are attributed quantitatively to the functioning of the product as far as possible. Currently, the scientific .
Manufacturing a product can be very complex. Raw materials come from many different sources, and obtaining each one of those materials involves a different series of inputs, outputs and processes, each of which has impacts on the environment.

Hence, the environmental impacts of a product are evaluated from cradle to grave, which means from the . These two standards underpin all good studies on LCA. According to the ISO standards there are four main stages of an LCA.
How far down the chain do I want to identify and quantify these material flows, and is that data even available? Data availability, Is data available to quantify material . Clearly defining the goal and scope of the study (including selecting a functional unit). Compiling a life cycle inventory ( LCI) — an inventory of relevant energy and material inputs and environmental .
