Along with ecological criteria, sustainable activity in particular also extends to consideration of economic aspects in process and product development, a comparison of variants etc. Life Cycle Costing (LCC) is suited as a method of supporting sustainable decision making, since it enables the analysis of economic aspects subject to the same system limits and boundary conditions as integrated ecological analysis, i.e. Life Cycle Assessment. The life cycle is defined here using the same criteria as for Life Cycle Assessment.
The Life Cycle Costing method allows assessment of all of the costs incurred by a product or service. For this purpose, all costs arising throughout the expected life cycle are registered and evaluated in a structured manner. The results of an LCC analysis above all serve the following purposes:
