Life Cycle Analysis [LCA] is the assessment of energy and other environmental impact and is specific to a product or component.

Broadly speaking, the more often it moves, moves fast or accelerates & decelerates,  the more competitive a carbon fibre component will be in an LCA comparison with other materials.

This generally means that the LCA needs to be a Whole Life LCA and not a Factory Gate LCA in order to be competitive.

A good example is the passenger jet.  it can be shown to have 20%

An LCA for a passenger jet will show a 20% saving when made with a great percentage of composites over the traditional all metal aircraft.
