In order to set achievable targets, it is necessary to have a baseline from which to compare products within a material or product category. In January, the Carbon Leadership Forum published the 2021 Material Baseline document (Version 1), a report that constituted a major update to CLF’s 2019 Beta Baseline, with improved data sourcing, citation, and categories. Version 2 builds upon these improvements with new categories and updated methods and documentation.<\/p>\n

Our present understanding of the importance of embodied carbon has been enabled by rigorous quantitative modeling that tracks carbon emissions across the full life of materials and products, using life cycle assessment (LCA)<\/a>.\u00a0In recent years, the building industry has adopted LCA as the globally accepted method for evaluating and communicating environmental impacts, and applied these methods to the study of materials, products, and assemblies. LCA data and results are essential for guiding science-based efforts to decarbonize buildings and infrastructure.<\/p>\n The Carbon Leadership Forum is part of a broad movement working to drive down the embodied carbon of building materials and products by encouraging the disclosure of high-quality embodied carbon data by manufacturers. It is essential that designers, owners, and policymakers have access to verified, third-party reviewed and published data on building materials and products in order to facilitate procurement decisions, set decarbonization targets, and inform design. One tool for achieving this goal has been the collection and use of Environmental Product Declarations (EPDs) to inform decision-making.<\/p>\n The development of a material baseline originated in support of the Embodied Carbon in Construction Calculator (EC3). The EC3 Baseline was originally published in 2019. This document supersedes the baseline dated May 2020. The EC3 tool and its open-access database of digital EPDs are one source for accessing and evaluating available EPDs and the relative carbon impacts that they report. Such databases support designers, owners, and policymakers in selecting low-carbon products during procurement and design. These databases are dynamic, updated constantly as new products are added and upstream data on key processes, such as carbon intensity of regional electricity grids, are revised.<\/p>\n <\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n Lifecycle assessment (LCA) LCA is a systematic methodology for compiling and examining the inputs and outputs of materials and energy, and the associated environmental impacts directly attributable to a building, infrastructure, product or material throughout its lifecycle (ISO 14040: 2006).<\/p><\/blockquote>\n [\/et_pb_text][et_pb_image src=”https:\/\/carbonleadershipforum.org\/wp-content\/uploads\/2021\/02\/factory-pipes-stairs-BW-750px.jpg” title_text=”factory-pipes-stairs-BW-750px” admin_label=”Foundry Image” _builder_version=”4.16″ _module_preset=”default” custom_margin=”||40px||false|false” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n EPDs are third party-verified documents based on LCA models, written in conformance with international standards, that report the environmental impacts of a product.

Still, the publication of EPDs and other carbon disclosure is voluntary and its adoption has been uneven. Because not all products or manufacturers are currently represented in public databases such as EC3, the ranges reported will very likely continue to be low estimates of the full material supply chain\u2019s carbon impacts, representing manufacturers that have voluntarily chosen to disclose the carbon footprint of their products. Due to the dynamic nature of these datasets, users have identified the need for a static baseline to compare results against, and against which they can set measurable targets.<\/p>\n Presently, the CLF publishes three figures in order to provide a picture of variability within a product category, according to the best publicly available data: High, Median, and Low. The baselines are intended to give a rough order of magnitude of embodied carbon impacts per category reflecting the significant variability of product manufacturing and uncertainty of LCA data available. Collectively, these values represent the expected range of embodied carbon impacts for most products in their category, taking variability and uncertainty into account.<\/p>\n The CLF Baseline<\/strong> represents a conservative, or \u201chigh\u201d estimate for embodied carbon in a product category. This value is intended to give a rough order of magnitude of embodied carbon impacts and represents a high<\/span> estimate of the embodied carbon footprint of a product if no effort is made to choose a low-carbon alternative. Most products in the category will fall below this threshold<\/em>. This CLF Baseline number can be considered a good starting point from which to develop carbon caps or reductions. For categories in which there are sufficient product-specific EPDs, the CLF Baseline is tied to the 80th percentile value of the category (i.e., the point where 80% of the results have values below this number) as represented in the EC3 database of published, peer-reviewed EPD results. The CLF Baseline is shown within the EC3 tool for all public categories.<\/p>\n The <\/span>CLF \u201cTypical\u201d Estimate<\/b> represents the median performance of products contained within a category. This value is tied to an industry-average EPD, if one is available and valid at the time of publication. <\/span>This number can be seen as a typical estimate for the category, representing standard manufacturing practice<\/span><\/em>. As such, it is appropriate to use this number as a rough estimate before products have been selected, or as a default value for broad product comparisons. Industry-average EPDs<\/a> are developed by industry associations representing multiple manufacturers and locations and declare the environmental impacts associated with an \u201caverage product\u201d in a clearly defined sector or geographic area.<\/span> Products covered in an industry-average EPD follow the same Product Category Rule (PCR) and have the same declared unit. All industry-average EPDs referenced by the EC3 database are published, peer-reviewed documents based on rigorous LCA models.<\/span><\/p>\n The CLF \u201cAchievable\u201d Estimate<\/strong> represents an achievable target, or a low value for the category, whereby at least 20% of products meeting the specification are better than this value. For categories in which more than 20 product-specific EPDs are available and where these products represent the range of materials and production expected within the category, this value has been based on 20th percentile figures in the EC3 tool and noted in the data citation. Products that meet this threshold could credibly be considered very low-carbon materials compared to those of similar performance and function. Where there is not yet sufficient data to support a confident estimate of the low value for the category, \u201cTBD\u201d (\u201cto be determined\u201d) appears in the table below.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.16″ global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/carbonleadershipforum.org\/wp-content\/uploads\/2021\/02\/yellow-shovel-750px.jpg” title_text=”yellow-shovel-750px” _builder_version=”4.16″ _module_preset=”default” custom_margin=”||40px||false|false” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text admin_label=”baseline col 2″ _builder_version=”4.16″ custom_padding=”||||false|false” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n A baseline is a static reference against which to compare progress towards a goal.

The CLF has made every effort to be fully transparent about the source and quality of data used to establish these baselines on a category-by-category basis.[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”Baseline Background NEW” _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_row _builder_version=”4.20.0″ _module_preset=”71ec4c3d-39eb-4479-a760-0015d42fc7bc” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text admin_label=”Tab Headline” _builder_version=”4.16″ global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ custom_padding_last_edited=”on|desktop” admin_label=”Two Column Row” _builder_version=”4.16″ custom_padding=”||||false|true” custom_padding_tablet=”|30px||30px|false|true” custom_padding_phone=”|20px||20px|false|true” border_width_bottom=”3px” border_color_bottom=”#FFAE00″ global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_2″ _builder_version=”4.16″ global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text admin_label=”Left Column Text” _builder_version=”4.16″ custom_margin=”|20px|||false|false” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n Baseline figures are representative of North American manufacturing, acknowledging global trade.\u00a0 The CLF Baselines represent Product Stage (A1-A3) carbon impacts \u2014 that is, the cradle-to-gate impacts from raw material extraction to manufacturing. This cradle-to-gate scope comprises the majority of embodied carbon impacts for the majority of materials, and is consistent with the scope of most product-specific EPDs<\/a>. Additional impacts from transportation and installation (A4\u2010A5) can also be considered in upfront embodied carbon and can be significant for some material categories, but are not included in these figures, as they are not currently required by many Product Category Rules for publication in Environmental Product Declarations (EPDs). As this data becomes available, it will be important for A4 and A5 impacts to be integrated into procurement decisions.<\/p>\n One notable exception to the A1-3 scope boundary has been made for foam insulation materials, where blowing agent emissions during installation and over the product\u2019s lifespan can be a significant contributor to the product\u2019s overall embodied GWP. Disclosing these impacts has been essential for the movement to replace hydrofluorocarbon (HFC) blowing agents with lower global warming potential (GWP) alternatives. Since insulation EPDs are required to include these impacts where applicable, the CLF Baselines for board and foamed-in-place insulations do account for additional lifecycle stages.<\/p>\n We are actively looking for help in refining these methods, and look forward to helping accelerate the standardization of calculation and reporting of uncertainty and variability in EPDs in order to improve the quality, quantity, and accessibility of embodied carbon data. If you are interested in engaging in the technical committees supporting methodology and data development, please email clfinfo@uw.edu for updates and forums for discussion, feedback, and continued research.[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text admin_label=”Right Column Text” _builder_version=”4.16″ custom_padding=”|||20px|false|false” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n Life Cycle Assessment is a comparative practice, and it is important for users to follow best practice in making appropriate comparisons between products and materials.\u00a0 The CLF Baselines represent a rough estimate of a product category\u2019s carbon footprint. However, in order to make material comparisons, it is incumbent upon a user to assure that the products, materials, or assemblies are functionally equivalent \u2014 i.e., that they serve the same purpose and meet the same performance standards within the building design. Please refer to the Embodied Carbon in the EC3 Tool: Methodology Report for future guidance on making appropriate comparisons.<\/p>\n Additionally, the EPDs in each of the broad categories include many unique products with unique performance characteristics that are not always possible to identify from the data currently included in EPDs. Better descriptions of the performance characteristics and creation of a digital EPD system could help overcome these limits.<\/p>\n The CLF Baseline figures do not represent the impacts associated with the full life cycle of a building assembly. Only the Product Stage (A1-A3) is included, as this represents the scope of most EPDs in the EC3 database. Baseline figures, therefore, do not include Transportation to site (A4), Installation (A5), Use (B1-B3) or End-of-Life (C1-C4) stages. (See note above for exception for insulation materials). Care should be taken when comparing materials or products with different use or end-of-life scenarios. In order to make cross-category comparisons or to assess a whole building over its full life span, more rigorous modeling must be conducted using a whole building LCA (WBLCA) tool with a full cradle-to-grave scope.[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”Updates” _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_row _builder_version=”4.20.0″ _module_preset=”71ec4c3d-39eb-4479-a760-0015d42fc7bc” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text admin_label=”Tab Headline” _builder_version=”4.16″ global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ custom_padding_last_edited=”on|desktop” admin_label=”Two Column Row” _builder_version=”4.16″ custom_padding=”||||false|true” custom_padding_tablet=”|30px||30px|false|true” custom_padding_phone=”|20px||20px|false|true” border_width_bottom=”3px” border_color_bottom=”#FFAE00″ global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_2″ _builder_version=”4.16″ global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text admin_label=”Left Column Text” _builder_version=”4.16″ custom_padding=”|||20px|false|false” global_colors_info=”{}” theme_builder_area=”post_content”]The Carbon Leadership Forum is publishing these baseline figures in support of the EC3 tool and other embodied carbon reduction initiatives, and will endeavor to update them annually.
