Life cycle thinking and product design: Don’t leave LCA to the last minute!
By Barbara Nebel, CEO , thinkstep-anz There is no such thing as a green product, only greener or more sustainable options. However, the differences in impact between products can be significant. This is an important distinction to make as it recognises that all products have some impact on the environment. Some common-sense knowledge and an overall understanding of how something is made and what it is made of can help you form ideas around how sustainable your product is. However, unless these ideas are tested and backed by credible data, they will remain as vague claims. This is where sustainability tool Life Cycle Assessment (LCA) comes into the picture to quantify a wide range of environmental impacts across a product’s whole life. In this article, we explore the principles behind LCA, the many uses and benefits of LCA, and how to optimise LCA to create the most sustainable products and services. Life cycle thinking and LCA Every product has a life cycle. It starts when the raw materials are harvested or extracted and finishes when the final product is disposed or used at the end of its functional life. Life cycle thinking — the concept around which LCA is built — understands that each stage of a product’s life cycle contributes to its overall environmental impact. Life cycle thinking also understands that sustainability is about more than just carbon. An LCA takes a broad definition of environmental sustainability with a wide range of indicators including carbon footprint, energy use, water consumption. Finally, life cycle thinking as a principle and LCA as quantitative tool understand that decisions around one area of a product’s sustainability can also affect others. Part of an LCA’s objective is to consider these trade-offs that can occur to ensure a positive impact in one area does not […]
