Sustainability has three interconnected pillars, namely<\/p>\n

    \n
  1. Planet;<\/li>\n
  2. Profit; and<\/li>\n
  3. People.<\/li>\n<\/ol>\n

    But what does this mean, and how does one measure or address each of these pillars?\u00a0 Let\u2019s first look at the \u201cPlanet\u201d pillar of sustainability. The other components will be addressed in upcoming blog posts.<\/p>\n

    A common way to classify the features of planet Earth is to include<\/p>\n

      \n
    • Land;<\/li>\n
    • Air; and<\/li>\n
    • Water.<\/li>\n<\/ul>\n

      Sustainability scientists use these same terms to measure the health of the Earth. Here are some measures we might consider for these terms.<\/p>\n

        \n
      • Land Health\n
          \n
        • terrestrial ecotoxicity;<\/li>\n
        • terrestrial acidification; and<\/li>\n
        • land occupation.<\/li>\n<\/ul>\n<\/li>\n
        • Water Health\n
            \n
          • aquatic ecotoxicity;<\/li>\n
          • aquatic acidification; and<\/li>\n
          • aquatic eutrophication.<\/li>\n<\/ul>\n<\/li>\n
          • Air Health\n
              \n
            • smog formation; or<\/li>\n
            • particulate matter.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

              What Is Life Cycle Assessment (LCA)?<\/h2>\n

              Life Cycle Assessment (LCA) is one of the tools we use to estimate impacts on our planet or the environment.\u00a0 LCA considers the effects of a process or product from cradle to grave, meaning that we consider all stages of the product\u2019s life from raw material extraction from the earth to disposal or recycling.<\/p>\n

              The LCA process is frequently used by designers to assess the potential impacts of their designs.\u00a0 You might have seen a company advertise that their new packaging material design saves x billion kg of carbon dioxide equivalent from entering the atmosphere.\u00a0 Or, perhaps a company will advertise that their new manufacturing process reduces sub 2.5-micron particulate matter by x tons per year.\u00a0 These are examples of statements companies make to communicate that they’re thinking about the Planet Pillar of Sustainability.<\/p>\n

              4 Critical Steps for Conducting an LCA Study<\/h3>\n

              Step 1: Define the Goal and Scope of the Study<\/h4>\n

              This step might sound simple and unimportant, but it is the foundation of the whole study<\/strong>.\u00a0 Ensuring that the study is well-defined allows us to draw comparisons between equivalent solutions.<\/p>\n

              Step 2: Prepare an Inventory<\/h4>\n

              In the manufacturing world, we think of this as the Bill of Materials.\u00a0 But in addition to just the Bill of Materials to manufacture the product, we include all<\/p>\n

                \n
              • Upstream Materials and Transportation<\/strong> for movement of the materials until we have the inventory in terms of raw materials from nature,\u00a0 and<\/li>\n
              • Downstream Materials and Transportation<\/strong>\n
                  \n
                • of the product to the customer;<\/li>\n
                • materials required during use;<\/li>\n
                • maintenance and repair; and<\/li>\n
                • finally, disposal or recycling.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                  We again define this in terms of raw materials from nature.
                  \nCreate an Inventory Flow Diagram<\/strong> to show flows from nature to nature, including<\/p>\n

                    \n
                  • water;<\/li>\n
                  • energy;<\/li>\n
                  • raw materials;<\/li>\n
                  • releases to land;<\/li>\n
                  • releases to air; and<\/li>\n
                  • lastly, releases to water.<\/li>\n<\/ul>\n

                    The inventory and associated flow diagram for even a simple product can be quite complex.<\/p>\n

                    Step 3: Perform an Impact Assessment<\/h4>\n

                    Each inventory item is associated with a potential environmental impact.\u00a0 Summing all the potential environmental impacts for each inventory item provide an estimated quantification of impact.\u00a0 Various software packages can assist with this assessment of impact.<\/p>\n

                    Step 4: Interpreting Results<\/h4>\n

                    The final step involves interpretation of the results, performing sensitivity analysis on the data, and making recommendations.<\/p>\n

                    So hopefully, the next time you see a company advertise that their redesigned product uses x million liters less water per year or their redesigned manufacturing process releases x million tons less particulate matter per year, you\u2019ll have an idea about the analysis that they went through to define that estimate for impact on our planet.<\/p>\n","protected":false},"excerpt":{"rendered":"
