WEBINAR: Practical Approaches for Reaching Carbon Neutrality with Your Concrete Construction Materials
February 19, 2025 | 2:00pm – 3:00pm ET
Achieving carbon neutrality requires an “all of the above” approach across infrastructure projects’ life cycles, and it starts with the manufacture of construction materials. That’s why the cement and concrete industry have developed a Roadmap outlining the opportunities and actions to reach carbon neutrality. The Roadmap involves the entire value chain, starting at the cement plant and extending through the entire life cycle of the built environment to incorporate the circular economy. This approach to carbon neutrality leverages relationships at each step of the value chain, demonstrating to the world that this industry can address climate change with ambition and audacity.
As an example of leveraging relationships to drive change, the cement and concrete industries have collaborated with government consumers, researchers, and other advocates to write voluntary guidelines that provide design professionals, contractors, code officials, elected representatives, non-governmental organizations, and the public with a framework for developing a lower carbon protocol for concrete. The voluntary guidelines address materials, methods, and metrics by integrating carbon reduction among all aspects of the built environment. A protocol developed with this approach is intended to lower the carbon of a concrete project without sacrificing long-term performance characteristics like strength, durability, and resilience while also advancing the circular economy.
Additional examples of putting Roadmap levers into practice include using blended cements and supplementary cementitious materials. Creating new cements with existing and even alternative materials reduces emissions from mining for new materials; and optimizing the amount of clinker used ensures emissions correspond to necessary production. For example, Portland Limestone Cement (PLC) is an existing lower-carbon blend, and its expanded acceptance and use will reduce clinker consumption and decrease emissions. Further, concrete mixes may be optimized when engineers and designers consider the specific needs of the construction project and use only the materials necessary. Optimizing the ingredients in cement and concrete not only enhance the benefits of cement-based construction materials, but it also reduces the carbon intensity of the final product.
