Lifecycle Assessment (LCA) is a comprehensive method used to evaluate the environmental impacts associated with all the stages of a product's life from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. By taking into account the entire lifecycle, LCA provides a thorough picture of the environmental aspects and potential impacts of a product system, making it an invaluable tool in the field of sustainable design. Unlike methods that focus solely on a single aspect of environmental impact, such as carbon footprint or water usage, LCA examines a wide range of environmental and resource concerns, thereby offering a holistic view of the ecological performance of products and services. This method is not limited to a qualitative analysis; rather, it quantifies and assesses how the choice of materials, processes, and the product’s use and end-of-life management affect the environment. This includes emissions to air, water, and soil, as well as the consumption of resources throughout the product's lifecycle. LCA is not a static tool but evolves with advancements in technology and methodology, enabling more accurate and comprehensive assessments. It does not prescribe specific actions but provides data and insights that inform decision-making in design, production, and policy-making towards more sustainable practices.

Lifecycle Assessment (LCA) is a comprehensive method used to evaluate the environmental impacts associated with all the stages of a product's life from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. By including an assessment of all stages in the product lifecycle, LCA provides a thorough picture of the environmental aspects and potential impacts related to a product, process, or service. This methodology is rooted in the principles of environmental science and is guided by standards such as ISO 14040:2006 and ISO 14044:2006, which set out the framework and requirements for conducting an LCA. The process of LCA is divided into four main phases: goal and scope definition, inventory analysis, impact assessment, and interpretation. Through its systematic approach, LCA helps designers, engineers, and business decision-makers to understand more fully the environmental impacts of their products and services, thereby enabling the identification of opportunities for improvement and the development of more sustainable solutions. The application of LCA can be seen across various sectors including industrial design, architecture, and consumer products, highlighting its versatility and importance in promoting environmental sustainability. Furthermore, the insights gained from LCA studies can contribute to strategic decision-making, policy development, and eco-labeling schemes such as those recognized by the A' Design Award, which emphasizes the role of design in achieving sustainability goals. By providing a quantifiable environmental impact assessment, LCA plays a crucial role in the advancement of sustainable design practices, encouraging innovation and the development of products that are not only functional and aesthetically pleasing but also environmentally responsible.
