Life-cycle Assessment

Life Cycle Assessment (LCA) is a systematic methodology for evaluating the environmental impacts associated with all stages of a product's life cycle, from raw material extraction (cradle) through production, distribution, use, and ultimately to disposal or recycling (grave). This comprehensive approach enables organizations to identify opportunities for environmental improvements and make informed decisions to reduce negative ecological effects.

Key aspects of Life Cycle Assessment include:

• Goal and Scope Definition: Establishing the purpose, boundaries, and level of detail for the assessment to ensure clarity and relevance.
• Life Cycle Inventory Analysis (LCI): Compiling an inventory of relevant energy and material inputs and environmental releases associated with the product system.
• Life Cycle Impact Assessment (LCIA): Evaluating the potential environmental impacts based on the LCI data, considering factors such as resource depletion, human health, and ecological consequences.
• Interpretation: Analyzing results to draw conclusions, make recommendations, and support decision-making aimed at reducing environmental impacts.

LCA is standardized under the ISO 14040 and ISO 14044 standards, ensuring consistency and credibility in its application. By providing a holistic view of environmental performance, LCA assists businesses, policymakers, and consumers in making sustainable choices.
