As the built environment accounts for nearly 40% of global greenhouse gas emissions, the spotlight is shifting from operational emissions (e.g., heating and cooling) to embodied carbon—the emissions associated with building materials and construction processes. Unlike operational emissions, which can be reduced over time through energy efficiency or renewable sourcing, embodied emissions are largely locked in once a structure is built.
Construction firms, developers, and architects are now under increasing pressure to evaluate and reduce these upfront emissions as part of a holistic decarbonization strategy. This article offers practical, actionable tips for minimizing embodied carbon in construction projects, from early design decisions to procurement and site execution.
The most impactful decisions in reducing embodied carbon happen during the design phase. Choosing a smaller, more compact building footprint can dramatically reduce the volume of materials required. Similarly, embracing performance-based structural design allows engineers to optimize load-bearing elements rather than over-engineering with safety margins.
Moreover, designing for adaptability and future reuse—what's known as "designing for deconstruction"—can extend the life of building components and enable circularity. By imagining a building's second life during its first, architects can help reduce future waste and emissions.
Concrete and steel remain the biggest contributors to embodied emissions, but the market for low-carbon alternatives is maturing. Blended cements with supplementary cementitious materials (SCMs) such as fly ash or slag can substantially reduce cement content. For structural steel, options with high recycled content produced in electric arc furnaces powered by renewables are now widely available.
Wood is also making a comeback—not just in small-scale buildings but in the form of mass timber, which can replace steel or concrete in mid-rise structures. When sourced responsibly, timber stores carbon while reducing reliance on energy-intensive materials. Environmental Product Declarations (EPDs) offer transparency and help teams compare the life-cycle impacts of various material options.
Reducing embodied carbon is not a solo act. It requires early and active engagement across the supply chain. Project owners and general contractors should communicate their carbon reduction goals to suppliers and subcontractors from the outset. Increasingly, developers are embedding embodied carbon targets into tender documents and scoring proposals not only on cost but also on environmental impact.
Collaboration with material innovators and manufacturers can yield bespoke solutions that align with project sustainability goals. In some cases, early supplier involvement can even lead to co-developing products with lower embodied carbon tailored to the specific performance needs of a project.
The old adage "you can't manage what you don't measure" holds especially true for embodied carbon. Lifecycle Assessment (LCA) tools such as One Click LCA, Tally, or EC3 allow project teams to quantify emissions across different material and design choices. These assessments are increasingly being required in green building certifications and investor ESG frameworks.
Importantly, embodied carbon should not only be measured at the design phase. Re-assessing at key project milestones—procurement, construction, and handover—ensures transparency and helps identify unexpected emission hotspots. Projects that integrate LCA into their Building Information Modeling (BIM) systems gain a significant advantage in tracking and optimizing material efficiency in real time.
Minimizing embodied carbon is one of the most immediate and effective ways to reduce the climate impact of the construction sector. It demands a shift in mindset—from focusing solely on how buildings operate to how they are made. Through intentional design, smart material selection, proactive supplier engagement, and robust measurement practices, developers can deliver projects that are not only structurally sound and economically viable, but also climate-conscious.
As climate expectations grow and regulations tighten, embodied carbon will no longer be optional data—it will be essential. Forward-thinking construction firms that act now will not only reduce emissions but also gain a strategic edge in a low-carbon economy.
