It is one technique for performing a life cycle assessment, an evaluation of the environmental impacts of a product or process over its entire life cycle. The method uses information about industry transactions - purchases of materials by one industry from other industries, and the information about direct environmental emissions of industries, to estimate the total emissions throughout the supply chain.<br> 112 <br>Economic Input-Output Life Cycle Assessment (EIO-LCA) is a method - a mathematically defined procedure using economic and environmental data to determine the effect of changing the output of a single sector. The method can be applied to any economy defined by the transactions between sectors. Each application of the method defines an EIO-LCA model. 113 </p> 114 <p class="u-text u-text-default u-text-3"><span style="font-weight: 700;">Also note that we have published two primary resources in support of LCA and IO-LCA:</span> 115 <br> 116 <br>1) A <a href="https://www.lcatextbook.com" class="u-active-none u-border-none u-btn u-button-link u-button-style u-hover-none u-none u-text-palette-1-base u-btn-1">free online LCA textbook - "Life Cycle Assessment for Decisions that Matter"</a> (Matthews, Hendrickson, and Matthews) that is periodically updated and covers many areas of LCA, not just EIO-LCA. <span style="font-weight: 700;">Chapter 8 of this book is focused on EIO-LCA and provides a great introduction to the method as well as examples from this website.</span> 117 <br> 118 <br>2) A "handbook" with Resources for the Future (RFF) Press in 2006 to help explain the EIO-LCA method and to show how to use it with examples:<br> 119 <br>* Hendrickson, C.
