In this process, for example, the environmental impact of various greenhouse gases such as methane (<sub>CH4<\/sub>) or nitrous oxide (<sub>N2O<\/sub>) is converted to the equivalent of carbon dioxide (<sub>CO2<\/sub>) and totaled to a single value, in this case the indicator is called global warming potential (GWP). <\/p>\n\n<h2 class=\"wp-block-heading\" id=\"interpretation-der-ergebnisse\">8.2.3 Interpretation of the results<\/h2>\n\n<p class=\"wp-block-paragraph\">When interpreting the results of LCIAs, care must be taken to ensure that analyses and comparative statements on different materials, components or buildings are only made on the basis of comparable functional units (functional equivalent) (e.g. a wall with comparable properties), but never in the declared unit such as piece, mass (kg), volume (<sup>m3<\/sup>). The latter would in most cases lead to incorrect interpretations of the results. To ensure that the results in EPDs are perfectly reproducible and comparable, it is also important that the data used are calculated on the basis of the same LCI databases wherever possible.  <\/p>\n\n<p class=\"has-theme-palette-7-background-color has-background wp-block-paragraph\"><sup>45<\/sup> ISO 14044:2006 &#8211; Environmental management &#8211; Life cycle assessment &#8211; Requirements and guidelines<\/p>\n\n<div class=\"wp-block-group has-theme-palette-7-background-color has-background\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Copyright<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This document is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License as Attribution-NonCommercial-ShareAlike<br\/>For more information see: <a href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/4.0\/\">Creative Commons<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"\/wp-content\/uploads\/2025\/10\/Bau_Zirku_Fig25.png\" alt=\"Creative Commons\"\/><\/figure>\n<\/div><\/div>\n","protected":false},"featured_media":0,"parent":6825,"menu_order":36,"comment_status":"open","ping_status":"closed","template":"","meta":{"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","_is_vendor_doc":"0","footnotes":""},"doc_tag":[],"class_list":["post-6765","docs","type-docs","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 5.0.3 - aioseo.com -->\n\t<meta name=\"description\" content=\"According to ISO 14044:200645, Life Cycle Analysis (LCA) is a three-part process from calculation to assessment to interpretation.
