Lebenszyklusarchitektur

Lebenszyklusanalyse, often abbreviated as LCSA, is a comprehensive methodology for assessing the environmental impacts of a product, process, or service throughout its entire life cycle. This "cradle-to-grave" or "cradle-to-cradle" approach considers all stages from raw material extraction and manufacturing to use, maintenance, and eventual disposal or recycling. The primary goal of LCSA is to identify and quantify the environmental burdens associated with each phase to inform decision-making and promote sustainability.

The process typically involves several key steps. First, a goal and scope definition clarifies the boundaries of the study and the intended application of the results. Second, an inventory analysis (LCI) is conducted to collect data on all relevant inputs and outputs, such as energy, water, raw materials, and emissions. Third, an impact assessment (LCIA) translates these inventory data into potential environmental impacts, categorized into areas like global warming, acidification, eutrophication, and resource depletion. Finally, an interpretation phase analyzes the results, identifies hotspots of environmental concern, and draws conclusions to guide improvements.

LCSA is a valuable tool for businesses, policymakers, and researchers. It helps in comparing the environmental performance of different products or processes, identifying opportunities for eco-design, and supporting policy development aimed at reducing environmental footprints. By providing a holistic view of environmental performance, LCSA contributes to a more informed and sustainable approach to product development and consumption.
