Unlike operational carbon from energy use, embodied carbon is already embedded in a structure from day one of construction.What is the definition of embodied carbon?
What is the definition of embodied carbon?
Embodied carbon refers to the total greenhouse gas emissions generated throughout the lifecycle of materials, from extraction and manufacturing to transportation, construction, maintenance, and disposal. Unlike operational carbon, which comes from a building’s energy use over time, embodied carbon is locked into its materials from the start.

Embodied carbon analysis
Embodied carbon analysis
For architects, engineers, and construction professionals, embodied carbon analysis helps guide material selection, structural efficiency, and reuse strategies to reduce a project’s carbon footprint. Beyond the built environment, embodied carbon analysis is also an essential parameter in environmental science, where it informs climate impact assessments, and in water treatment, where material choices affect infrastructure sustainability. Public health experts consider embodied carbon in the context of air quality, resource depletion, and the broader environmental factors that influence community well-being. Integrating embodied carbon considerations is essential for driving sustainable innovation as industries work toward carbon reduction goals.

The embodied carbon lifecycle
Embodied carbon refers to the greenhouse gas emissions at every stage of a building or piece of infrastructure’s lifecycle, namely:Â
Extraction of raw materials
Transportation (before and after processing)
Processing and manufacturing
Construction
Maintenance and renovation
Demolition and disposal
By using embodied carbon analysis to build a picture of carbon use through all of these stages, changes and improvements can be made to reduce carbon overall.

Architects, engineers, and builders can significantly reduce a projects embodied carbon through thoughtful material choices, reuse strategies, and supply chain awareness.How to decarbonize construction work
How to decarbonize construction work
Decarbonizing construction starts with intentional choices that reduce a building’s carbon embodied footprint before it is built. Low-carbon materials—such as mass timber, recycled steel, and low-carbon concrete—can drastically cut emissions, while optimizing designs for material efficiency minimizes waste. Adaptive reuse and modular construction further reduce demand for carbon-intensive materials, keeping valuable resources in circulation and extending their lifespan. By embracing circular economy principles, such as deconstruction planning and material repurposing, the industry can shift from a waste-heavy model to one that prioritizes sustainability and resilience.
True impact comes from collaboration. Architects, engineers, and builders must work together to assess and lower embodied carbon using life cycle assessments (LCAs) and environmental product declarations (EPDs). Partnering with suppliers who prioritize transparency and innovation in manufacturing can push the industry toward lower-carbon solutions. By embedding decarbonization strategies early in the design and procurement process, professionals can create more sustainable buildings and a more climate-resilient future.

Software like Autodesk Forma makes it easy to perform embodied carbon analyses early in the design process.How is embodied carbon measured?
How is embodied carbon measured?
Understanding how to calculate embodied carbon is essential for reducing the environmental impact of buildings. Embodied carbon assessment determines emissions across a material’s lifecycle, from raw material extraction and manufacturing to transportation, construction, maintenance, and disposal. A life cycle assessment (LCA) is the standard method used, relying on data from environmental product declarations (EPDs) and industry databases to quantify emissions. Tools like an embodied carbon calculator or a concrete embodied carbon calculator help designers, engineers, and contractors compare materials and make informed choices that lower a building’s overall embodied carbon footprint.
For those wondering how to calculate embodied carbon in a building, several key factors come into play. Material selection, transportation distances, construction methods, and a material’s expected lifespan all influence total embodied carbon. Many professionals use embodied carbon calculations to analyze emissions at different project stages, ensuring carbon reduction strategies are integrated early in the design process when changes carry the lowest cost risk. For example, Autodesk Forma’s Embodied Carbon Analysis tool enables designers to gain a more thorough understanding of carbon impacts from building form, structure, and primary material choices during site feasibility and massing studies that happen at the start of the project planning process. Leveraging these embodied carbon reporting tools during early concept planning gives teams the greatest opportunity to impact decisions that contribute to a low-carbon built environment.

Frequently asked questions (FAQ) on embodied carbon
Among common building materials, aluminum has the highest embodied energy, ranging from 200–250 MJ/kg, due to its energy-intensive extraction and refining process. Other high-energy materials include plastic (80–120 MJ/kg), copper (40–50 MJ/kg), and steel (20–35 MJ/kg), while materials like concrete (1–2 MJ/kg) and timber (8–12 MJ/kg) have significantly lower embodied energy. However, recycling drastically reduces these impacts—recycled aluminum uses only 5–10% of the energy required for virgin production, and recycled steel is far less carbon-intensive than its virgin counterpart. This underscores the importance of material reuse, recycling, and low-carbon alternatives in reducing embodied carbon in construction.
Calculating the embodied energy of building materials involves measuring the total energy required across their lifecycle, from extraction and processing to transportation, construction, use, and disposal. This is typically done using environmental product declarations (EPDs), life cycle assessments (LCAs), and industry databases that provide embodied carbon energy values in megajoules per kilogram (MJ/kg). The total embodied energy is determined by multiplying a material’s energy factor by the quantity used, while also accounting for transportation distances and construction methods. Tools such as embodied energy databases, LCA software (such as One Click LCA, Tally), and embodied carbon calculators help professionals make data-driven decisions to reduce energy-intensive materials and prioritize sustainable alternatives.
The embodied energy of particleboard typically ranges from 8–12 MJ/kg, influenced by factors such as material sourcing, adhesive content, and manufacturing processes. Made from wood chips and sawdust bonded with resins, particleboard has a moderate amount of embodied carbon – higher than solid timber but lower than synthetic materials like plastics. The use of recycled wood fibers helps reduce its environmental impact, though factors like resin type, pressing techniques, and transportation distances can affect its total energy footprint. When sourced responsibly and manufactured with lower-carbon processes, particleboard can be a more sustainable alternative to virgin wood-based panels.
