Material Collection

Low Embodied Carbon Materials

31% of global carbon emissions come from making things – which means that manufacturing materials and products contribute significantly to the changing climate. Until recently, most attention on carbon emissions within the building industry focused on energy consumption from operating buildings once they are inhabited. But carbon emitted from the production, transportation, installation, maintenance, repair, and disposal of a building product is also significant.

This list considers emissions before a product is transported to the construction site. We look specifically at greenhouse gas emissions from extracting raw materials, transportation to the factory, and manufacturing a product (A1-A3 of a product's lifecycle).

Currently, there is no universal threshold for 'low embodied carbon' in materials. After discussing this research with experts, we set a rigorous standard that can meet 2030 goals. These products, labeled with 'LEC', embody below 5 kgs of CO₂eq per square meter.

*Products in this collection meet criteria for both material health and low embodied carbon.

Below are a few examples of low embodied carbon materials that meet our rigorous evaluation. For further help on your own search, scroll down to "Spec Guidance”.

Wool Batt Insulation

Low-Embodied Carbon Material

Sheep's wool provides a healthy and comfortable choice for insulation. Wool is naturally flame resistant. Additionally, wool's unique structure (a hydrophobic exterior and hydrophilic interior) allows it to absorb up to 35% of its weight in moisture from a room. When used as insulation, this gives wool the unique capacity to manage both humidity and temperature. Batt insulation requires the material to hold its shape. Traditional batts are held together with chemical additives. Havelock Wool's uses needle punching to hold their product together, avoiding toxic chemicals.

Per Havelock's EPD, this product meets HML's criteria for low embodied carbon. Havelock's wool insulation are produced in Reno, NV, making its application most impactful on projects in western United States.

EcoWorx Carpet Tile

Available At the Donghia Materials Library
Low-Embodied Carbon Material

Patcraft's EcoWorx carpet tile is a non-PVC backed carpet tile. Per manufacturer, all EcoWorx carpet tile with nylon are Cradle to Cradle Certified® Silver. Reverse is an exception, as the manufacturer set out to obtain a Gold level certification. Using a carefully curated selection of yarn colors for the collection, the styles of Reverse were able to pass the Cradle to Cradle Product Standard's Restricted Substance List (RSL) to achieve Gold in the Material Health pillar. This HPD relates to several EcoWorx collections, including Reverse and Artefact. All pigments fall below the 1000 ppm reporting threshold for the HPD and most pigments fall below the 100 ppm threshold for Declare, hence no need for separate (HPD/Declare) certifications for the C2C Gold collection. Shaw guarantees free reclamation and recycling at the end of use.

Per Patcraft's product-specific EPD, this product meets HML's criteria for low embodied carbon.

Thermowood

Low-Embodied Carbon Material

Lunawood Thermowood avoids chemicals in its manufacturing processes, relying solely on a treatment with high heat and steam that enhances the wood's durability. This allows for an extended lifetime and a surface that requires no finishing and less routine maintenance, regardless of climate. However, applying paints, oils, and other finishes is possible (please see HML's list of healthier finishes for recommendations). Since the processing eliminates natural resins, no resin will secrete through any applied finish or paint.

Per EPD, this product meets HML's criteria for low embodied carbon.
