As sustainability becomes a cornerstone of construction practices, understanding and minimizing the carbon footprint of building materials is crucial. The carbon footprint quantifies the greenhouse gas emissions generated throughout a material’s lifecycle—from extraction and manufacturing to transportation, installation, use, and end-of-life disposal or recycling.
This blog explains how to effectively evaluate the carbon footprint of building materials, why it matters for sustainable construction, and how Buildix ERP can help construction teams manage material choices aligned with carbon reduction goals.
Why Assessing Carbon Footprint of Materials Matters
Materials often account for a large portion of a building’s embodied carbon—typically 10% to 20% or more of the total project emissions. Selecting low-carbon materials can significantly reduce overall environmental impact and help meet increasingly stringent regulations and green building standards such as LEED, WELL, and Canada’s Net Zero Carbon Building Standard.
Evaluating the carbon footprint supports:
More informed material sourcing decisions
Cost-effective pathways to carbon reduction
Transparent sustainability reporting for clients and regulators
Identification of trade-offs between embodied and operational carbon
Steps to Evaluate Carbon Footprint of Building Materials
1. Define the Scope
Determine which stages of the material lifecycle to assess. Common stages include:
Raw material extraction and processing
Manufacturing and fabrication
Transportation to site
Installation and construction impacts
Use phase impacts (if applicable)
End-of-life disposal, reuse, or recycling
Clear scope definition ensures consistent, comparable evaluations.
2. Collect Life Cycle Inventory (LCI) Data
Gather data on energy use, emissions, and waste associated with each lifecycle stage. This data can be obtained from:
Environmental Product Declarations (EPDs)
Manufacturer data and certifications
Industry-average databases like ICE (Inventory of Carbon and Energy)
3. Calculate Carbon Emissions
Use LCI data to estimate CO2-equivalent emissions for each stage. This involves applying global warming potential factors to different greenhouse gases.
4. Analyze and Compare
Evaluate emissions per unit (e.g., kg CO2e per kg of material or per square meter) to compare different materials or sourcing options. Consider durability and expected lifespan in the comparison.
5. Integrate with Project Decisions
Use carbon footprint data alongside cost, performance, and availability to select materials that best meet sustainability goals and budget.
Common Low-Carbon Building Materials
Engineered Wood Products: Such as cross-laminated timber (CLT), which stores carbon and requires less energy than concrete or steel.
Recycled Content Materials: Including recycled steel, plastic lumber, and concrete aggregates.
Geopolymer Concrete: Produces significantly fewer emissions compared to traditional Portland cement.
Natural Insulation: Materials like cellulose or sheep wool with low embodied carbon.
