Everything we do to make our homes more sustainable has an environmental impact—even the materials we use. While we often focus on saving energy and using clean electricity, it’s important to also consider the carbon footprint of the products we choose. This hidden impact is called embodied carbon.

What Is Embodied Carbon and Why Is It Important?

Embodied carbon refers to all the greenhouse gas emissions generated during the lifecycle of a product—from extracting raw materials, through manufacturing, transport, and installation. It’s often called ‘upfront carbon’ because these emissions are locked in before the material even enters your home.

Understanding embodied carbon gives us a complete picture of a product’s environmental cost. It helps us make smarter, more climate-friendly choices when renovating or building.

What Is the Difference Between Embodied and Operational Carbon?

• Embodied carbon is released during the creation and delivery of materials.
• Operational carbon is produced by running your home—heating, cooling, lighting, etc.

While operational emissions can be reduced over time, embodied carbon is set once materials are installed, making early decisions critical.

Should We Consider Embodied Carbon During a Net Zero Retrofit?

Absolutely. If we reduce operational emissions but use high-carbon materials, we may undermine our sustainability goals. A true Net Zero retrofit focuses on:

• Using less energy
• Transitioning to renewable sources (like electricity)
• Choosing low or carbon-storing materials

This means opting for plant-based or recycled materials over petroleum-based ones.

Does Embodied Carbon Really Matter?

Yes—and often more than you think. In some cases, a building can emit more carbon during construction than it will over decades of operation.

That’s why choosing low-embodied carbon materials is essential. Some materials even store carbon, turning buildings into part of the climate solution.

Construction is one of the few sectors that can become carbon-negative through carbon-sequestering materials and efficient design.

Which Materials Have High or Low Embodied Carbon?

When planning a Net Zero retrofit, be selective:

• High Embodied Carbon: Foam insulation, concrete, steel, plastics
• Low/Carbon-Storing: Wood fiberboard, cellulose, straw, hemp, waste textiles, wool

For example, foam insulation is energy-efficient but carbon-intensive to produce. Natural alternatives like hemp or cellulose not only reduce energy use but also store carbon.

Did you know? Foam insulation contains 5–20% flame retardants—toxic substances that make it unsuitable for healthy homes.

Natural materials offer equal or better energy efficiency, are healthier for your family, and better for the environment.

How Is Embodied Carbon Calculated?

Embodied carbon is calculated by analyzing:

• Material ingredients
• Manufacturing processes
• Transportation and installation steps
