Reducing Embodied Carbon in New Home Builds
May 4, 2025 | This post was written in collaboration with Karen Ramsey of Building Wellness. We are so honored to have Karen’s wealth of knowledge in construction and green building for this fantastic resource! Find out more about Karen below.
As a sustainability strategist based in beautiful Colorado, I’m passionate about creating a future where homes are not just structures, but eco-friendly sanctuaries that harmonize with nature. In our fight against climate change, one of the most significant aspects we must address is embodied carbon—the carbon dioxide emissions generated during the extraction, production, transportation, and installation of building materials. With new home builds on the rise, understanding and reducing embodied carbon is critical for both the environment and our communities.
Understanding Embodied Carbon
Embodied carbon refers to the total greenhouse gas emissions associated with a building’s construction materials and processes. It encompasses everything from the extraction of raw materials to their manufacturing, transportation, and eventual installation. According to the World Green Building Council, embodied carbon can account for a staggering 50% of a building's total lifecycle emissions. This means that if we want to make a real impact on reducing carbon footprints, we must focus not just on how buildings operate, but also on how they’re built. By prioritizing low-carbon materials and sustainable building practices, we not only safeguard our environment but also create healthier living spaces. It's a win-win!
The Exciting Journey to Reduce Embodied Carbon
Reducing embodied carbon doesn’t have to be a daunting task. In fact, it can be an exciting journey filled with innovation, creativity, and collaboration. Let’s talk about some strategies to help you reduce embodied carbon in your new home build.
1. Choose Sustainable Materials
One of the most impactful ways to reduce embodied carbon is by selecting low-carbon materials. Opt for locally sourced and sustainably harvested resources to minimize transportation emissions and support local economies. For example, consider using reclaimed wood or local quarry stone, which have lower carbon footprints than traditional materials like concrete and new lumber.
In Colorado, we have a growing circular economy focused on textile waste, shingles, and plastics. Check your local resources for recycled building material suppliers. By working with local suppliers, you can not only reduce your carbon footprint but also celebrate the beauty of our state’s natural resources.

2. Embrace Innovative Building Techniques
Advancements in construction technology provide exciting opportunities to lower embodied carbon. Techniques such as panelized construction or off-site fabrication can significantly reduce waste and emissions. These methods allow for more efficient use of materials and can accelerate the building process, leading to cost savings and reduced environmental impact.
Additionally, consider using advanced insulation techniques, which optimize the amount of natural materials used in construction while meeting or even exceeding the energy efficiency and R-value of traditional fiberglass batt insulation. Some natural insulation options that we love to incorporate in our designs are hemp fiber, sheep wool, and wood fiber. Straw, if installed correctly, is a fantastic insulator and has the lowest carbon footprint because it requires no processing from the field to the site. The combination of innovation and sustainability can make your home both cutting-edge and eco-friendly!

3. Design for Longevity and Adaptability
Designing your home for durability and adaptability is another effective way to reduce embodied carbon. A well-designed home can withstand the test of time, reducing the need for future renovations or replacements that contribute additional carbon emissions.
Incorporating flexible spaces into your design allows you to adapt your home to changing needs, whether it’s adding a home office or accommodating a growing family. By creating a versatile living environment, you can maximize the lifespan of your home and minimize the need for renovations down the road which reduces its overall carbon footprint.
“Efficient space planning significantly reduces a building's footprint and the materials needed, leading to lower embodied carbon and construction costs. By optimizing space utilization, designers can minimize the overall building area, consequently requiring less material to construct…. The reduced material requirements also directly translate into upfront cost savings for construction.”
4. Collaborate with Sustainability Experts
The journey to reducing embodied carbon can be enhanced by collaborating with architects, builders, and sustainability experts who prioritize eco-friendly practices. These professionals can guide you in making informed decisions about materials, design, and construction methods that align with your sustainability goals.
Regardless of where you’re building, be sure to engage with local experts who understand the unique challenges and opportunities of your local environment. Their insights can help you navigate the complexities of reducing embodied carbon while ensuring your vision for your home comes to life.
The Bigger Picture: Creating a Sustainable Community
Reducing embodied carbon in new home builds is not just an individual effort; it’s a collective responsibility. By making conscious choices in our construction practices, we contribute to a more sustainable future for our communities and the planet. In Colorado, where outdoor recreation and natural beauty are paramount, embracing sustainability in our homes reflects our commitment to preserving these treasured resources for future generations. Let’s embark on this exciting journey together—one home at a time!
