The production of cement alone accounts for 70% to 90% of the emissions from concrete, with the calcination reaction being responsible for what is estimated as over 60% of these emissions.
Sabbie Miller, Director of the UC Davis Materials Decarbonization and Sustainability Center, recently published an article in NAE Perspectives, exploring critical strategies for reducing greenhouse gas (GHG) emissions associated with concrete production.
Concrete, a globally essential building material, is responsible for over 7% of anthropogenic CO₂ emissions, primarily due to the cement it contains. Miller’s article addresses the complex challenges and opportunities in reducing the carbon footprint of this material, essential for infrastructure but intensive in emissions. She examines a range of decarbonization strategies, from improving material efficiency to adopting alternative binders and emerging technologies like carbon capture and storage.
Miller emphasizes the importance of a tiered approach to decarbonization, balancing the need for sustainable materials with performance and economic feasibility. Her insights highlight the urgency of adopting validated low-carbon solutions alongside ongoing innovation, underscoring that early action across the industry is critical in minimizing environmental impacts.
