elutsüklihindamisteni, often abbreviated as LCA, is a systematic framework used to assess the environmental impacts associated with all stages of a product's life, from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. This approach provides a comprehensive understanding of a product's environmental footprint by considering the entire lifecycle.

The process of conducting an LCA typically involves several key stages. First, a goal and scope definition is established, outlining the purpose of the study, the product system being analyzed, and the functional unit, which is a measure of the function of the product system to be studied. Second, an inventory analysis is performed, which involves collecting and quantifying all relevant inputs and outputs of the system, such as energy and raw material consumption, and environmental emissions. Third, an impact assessment translates these inputs and outputs into potential environmental impacts, categorized into areas like climate change, acidification, eutrophication, and ozone depletion. Finally, an interpretation of the results allows for drawing conclusions and making recommendations based on the findings, often to identify areas for environmental improvement or to compare different product options.

LCAs are valuable tools for decision-making in various fields, including product design, policy development, and environmental management. They can help identify environmental hotspots in a product's lifecycle, inform strategies for reducing environmental burdens, and support the development of more sustainable products and practices. Despite its comprehensiveness, LCA is complex and data-intensive, and its results can be sensitive to assumptions and data quality.
