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 of a product, LCA helps in identifying opportunities to improve the environmental performance of products at various points in their lifecycle. It is not merely an analysis of the end-of-life phase of products, nor is it limited to the assessment of carbon footprint or energy consumption. Instead, LCA considers a wide range of environmental impacts, including resource depletion, water and air pollution, greenhouse gas emissions, and biodiversity loss. This holistic approach enables designers, engineers, and policymakers to make more informed decisions that contribute to more sustainable production and consumption patterns. The methodology of LCA is standardized by the International Organization for Standardization (ISO) in the ISO 14040 and 14044 series, ensuring a consistent framework for conducting these assessments. Through the phases of goal and scope definition, inventory analysis, impact assessment, and interpretation, LCA provides a detailed insight into the environmental aspects and potential impacts of product systems, offering a valuable tool for achieving sustainability in design and manufacturing processes.

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 the entire lifecycle, LCA provides a thorough perspective on the environmental aspects and potential impacts of a product system. Its applications can be found across various sectors of design, including industrial design, architecture, and fashion design, serving as a critical tool for sustainability assessment. The methodology of LCA is structured around four main phases: goal and scope definition, inventory analysis, impact assessment, and interpretation. This process helps designers, engineers, and business decision-makers to compare materials, processes, and products, identifying more sustainable options. The historical development of LCA dates back to the early 1960s, with significant advancements in the 1990s as environmental awareness and the desire for more sustainable products grew. LCA has been instrumental in guiding design decisions, promoting the use of more sustainable materials, and optimizing production processes to minimize environmental impacts. The A' Design Award, recognizing the importance of sustainable design practices, has categories dedicated to eco-friendly and sustainable designs, encouraging designers to incorporate LCA in their design process. The cultural and societal impact of LCA is profound, as it reflects a growing global concern for environmental sustainability and influences consumer choices towards more sustainable products. Technologically, LCA has evolved with the development of sophisticated software tools that facilitate the complex analysis of life cycle stages, making it more accessible to designers and companies aiming to reduce their environmental footprint. As sustainability becomes increasingly paramount in design, the role of LCA is expected to expand, guiding future innovations and sustainable development within the design industry.
