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 2 kgs of CO₂eq per square meter.

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

About Our Collections

The goal of our collections is to help promote transparency in the material ingredients of building products by fostering knowledge and awareness of products and materials for which life-cycle information is available, and that have environmentally, economically, and socially preferable life-cycle impacts.

Keep an eye out for the following symbols:
A Healthier Affordable Building Product

Products with the designation of "Healthier & Affordable" were specified and installed in at least one of our Case Studies of healthier affordable housing.

Ingredient Disclosures

There are several ways of evaluating a material’s health that we include with product information. Disclosures are reports by manufacturers about product ingredients, impacts, or other attributes.

Key Disclosures include:
Health Product Declaration (HPD)

A voluntary technical specification for reporting information on product contents and associated health information, intended to be the health-analogue to Environmental Product Declarations (EPDs).

Declare Label

Declare is a transparency platform and product database that answers three questions: 
  1. Where does a product come from?
  2. What is it made of?
  3. Where does it go at the end of its life?

Environmental Product Declaration (EPD)

A standardized format for communicating the environmental effects associated with a product’s raw materials extraction, energy use, chemical makeup, waste generation, and emissions to air, soil, and water.

Safety Data Sheet (SDS)

A reporting format that provides basic information about a material’s chemical ingredients, the potential safety hazards to installers, and recommended practices for installation.

Roxul Safe

A Healthier Affordable Building Product
Available At the Donghia Materials Library
Low-Embodied Carbon Material

Safe is a batt insulation made from mineral wool that provides acoustic dampening and is non-combustible. Safe is Greenguard Gold Certified, meaning it meets strict requirements for VOC and formaldehyde emissions.

This product meets HML low embodied carbon standards per Rockwool's EPD for its stone wool insulation. Production facilities are located in the US and Canada. For shorter transportation, the North American Market is therefore preferable. Rockwool's Ontario location uses the highest amount of recycled material of any of its facilities.

*NOTE: This product contains phenol formaldehyde. According to the manufacturer:

"Phenol formaldehyde is allowed in rigid mineral wool insulation for exterior applications (such as rain screen assemblies or foundation insulation). While rigid mineral wool insulation does contain some formaldehyde, most of the formaldehyde is eliminated in the production process through a chemical reaction and high heat. Rigid mineral wool insulation installed on the exterior of the building possess less risk to humans and ecosystem than rigid foam insulation products, which almost always contain HFRs and use blowing agents with high global warming potential."

Natural Wooden Flooring

Available At the Donghia Materials Library
Low-Embodied Carbon Material

mafi is an Austrian company that specializes in the production of three-layer wooden planks that can be used as flooring, walls, or ceilings. mafi floors are finished using natural oils. Instead of creating a seal-like more typical lacquers, the oil soaks into the wood and protects it from the inside out. Because it does not create a barrier, the oil finish on mafi’s wood floors allows the material to breathe and to help regulate the interior climate and improve indoor air quality. The natural oil finish is also free of toxic solvents. All of the wood used in mafi's flooring is grown in Austria, within 12km ( 8 miles ) of the factory.

Graphenstone

Low-Embodied Carbon Material

Graphenstone has updated traditional lime paint formulas with their product by adding graphene, a material made from carbon. Graphene lends the paint extreme strength, durability, and washability. Additionally, the use of lime creates a paint that is not only free of harmful substances, but one that also actively improves indoor air quality by absorbing toxics and CO2. The white interior and exterior paint have a Cradle to Cradle Gold certification.

This product meets HML's criteria for low embodied carbon in part because of its use of renewable energy and CO₂ absorbing ingredients. As the product is produced in Spain, shipping can negate it's low emission score.

*NOTE: Recently, researchers have raised health concerns about graphene. According to the manufacturer, Graphenstone uses Nano Fibers of Graphene (NFG), which has a larger structure that is not harmful to human health.

EcoWorx Carpet Tile

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.

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.
*Note: Havelock's Loose Fill Insulation has R values of 4.3 and also meets HML's criteria for low embodied carbon.

Spec Guidance

Prefer carbon sequestering materials whenever possible. Examples include timber, hempcrete, plant fibers, wool, clay, and lime.

Prefer locally produced products. Carbon emissions from transporting products increase the overall footprint and may lead to a product becoming a large source of carbon emissions.

Consider reuse and retrofit rather than new construction whenever possible.

Reconsider structure and foundation. Steel and concrete are currently the largest sources of CO₂eq in the built environment. Timber structures sequester rather than emit carbon.

Consider installation details that do not require adhesives (which have high embodied carbon).

Encourage manufacturers to analyze the environmental impact of their products and provide EPDs.

Look for products with EPDs that indicate *low or no Global Warming Potential (GWP) per functional unit.

Consider conducting a Life Cycle Assessment (LCA) of your project before beginning.

Consider the ratio of renewable to nonrenewable energy being used in the manufacturing of a product.
