It is used broadly across various industries and sectors and there is an entire community of LCA-certified professionals globally who are technical experts in using and applying this methodology and interpreting the results.<\/p>\n\n\n\n<p>In the apparel, textile, and footwear industry today, LCA data is used as the primary means to understand the environmental impacts related to raw materials and finished products at a broad scale. It is used to calculate impact assessments for companies and the industry (including greenhouse gas [GHG] footprints).<\/p>\n\n\n\n<p><strong>Limitations and Realities<\/strong><\/p>\n\n\n\n<p>Textile Exchange believes that LCA methodology, when applied to raw materials used by the apparel, textile, and footwear industry, has some key limitations as it stands today:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>LCA does not capture certain impact areas that Textile Exchange feels are important to a holistic view of the impacts associated with raw material production, such as biodiversity, soil health, animal welfare, and social impacts.<\/li>\n\n\n\n<li>It is extremely cost-prohibitive and resource-intensive to conduct a single LCA study on a raw material \u2013 hundreds of data points must be collected to capture the breadth of impacts related to the specific production system and geographic location. LCA studies also only capture what is happening at a single point in time. This means that use of LCA data to capture the impacts of materials in use by a brand or by the industry at large is often in a \u201cproxy\u201d capacity, providing an estimate of impacts related to materials rather than primary data.<\/li>\n\n\n\n<li>The system boundaries defined for LCA studies can vary within and across fiber types, given the variations in production systems (particularly agricultural systems.) Additionally, there are different functional properties associated with different fibers and materials. For these reasons, it is never recommended to directly compare LCA data from different fiber categories, i.e. polyester against cotton \u2013 it is not an \u201capples to apples\u201d comparison.<\/li>\n\n\n\n<li>Results from LCA studies can be presented in multiple ways \u2013 for example, \u201cglobal averages\u201d or regional impacts. Global average results cannot be used to differentiate impact across geographies and must be interpreted with care, as not all sourcing locations may be considered within the average calculation. Differences between and across regional impacts may be lost when aggregating at a global level.<\/li>\n\n\n\n<li>Within LCA methodology, from study to study, there can be significant variability in the scope of what is covered as well as in other assumptions that are made. This means that a comparative LCA framework or database such as the Higg Index Materials Sustainability Index [MSI] or Quantis WALDB can be employed to ensure that all&nbsp;parameters used in each study are consistent. The same consistency can also be achieved through a specific peer review process.<\/li>\n<\/ul>\n\n\n\n<p>It is also important to note that these limitations are consistent across any application of LCA, in any industry\u2013 these challenges are not unique to the apparel, textile, and footwear industry.<\/p>\n\n\n\n<p><strong>An \u201cLCA+\u201d Approach<\/strong><\/p>\n\n\n\n<p>At Textile Exchange, we believe in an approach to impact data we call \u201cLCA+\u201d. This approach can help the industry fill key gaps in LCA data and methodologies, while also investing in the identification of additional impact data approaches to address other important impact areas not covered by LCA methodology today, such as biodiversity and soil health.<\/p>\n\n\n\n<p><strong>A Note on the 2014 Textile Exchange Organic Cotton LCA<\/strong><\/p>\n\n\n\n<p>The LCA of Organic Cotton published by Textile Exchange in 2014 was the first of its kind for organic cotton. Thinkstep (formerly PE International, now part of Sphera) \u2013 the same consultancy that had prepared LCAs for other cotton-based growing systems \u2013 was specifically commissioned to conduct the study to ensure consistency in methodology and software used, and the study was conducted in accordance with ISO standards 14040 and 14044. The data within the study is sound and should continue to be used as appropriate within LCA databases.<\/p>\n\n\n\n<p>The LCA \u201cSummary of Findings\u201d highlighted some comparative data between the 2014 Organic Cotton LCA and a 2012 LCA of U.S.-grown conventional cotton, conducted by Cotton Incorporated. These comparative numbers, including a finding of 91% water savings for organic cotton, were only intended to be considered within the context of these two specific studies. The LCA results demonstrate that at the point in time that the LCA study was conducted, there were differences in water consumption between the organic farms and the conventional farms sampled; however, this does not mean that switching from conventional to organic practices at an individual farm level will automatically result in this specific amount of water reduction. Textile Exchange is aware that there have been instances in which this comparative number has been extrapolated to make specific claims about the water savings associated with a cotton-based product or to make broader claims about organic vs. conventional cotton at large. This is not an appropriate use of LCA data.<\/p>\n\n\n\n<p>As our industry \u2013 including our organization \u2013 builds its technical, scientific understanding of LCA data and its appropriate use, we will continue our efforts to provide industry education and capacity-building around how LCA data should and should not be used. Our recommendation is always for members to seek advice from a trusted legal professional regarding any claims they wish to make about their products or materials.<\/p>\n\n\n\n<p>For more detailed information about using LCAs within the apparel, textile, and footwear industry, we recommend the following resources (please reach out to Textile Exchange if you know of others we should include in this list):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/aclca.org\/about\/\" target=\"_blank\" rel=\"noreferrer noopener\">American Center for Life Cycle Assessment (ACLCA)<\/a>&nbsp;<\/li>\n\n\n\n<li><a href=\"https:\/\/ecochain.com\/knowledge\/life-cycle-assessment-lca-guide\/\" target=\"_blank\" rel=\"noreferrer noopener\">Life Cycle Assessment Complete Beginner\u2019s Guide \u2013 Ecochain<\/a>&nbsp;<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A Life Cycle Assessment (LCA) provides a framework for measuring the environmental impacts of products or services.
