Supporting reduced greenhouse gas emissions and resource consumption across key stages of the concrete lifecycle—spanning raw material sourcing, manufacturing, construction, use, and end-of-life—is essential to reducing resource consumption and greenhouse gas (GHG) emissions.
Reduce binder-related CO₂ emissions while maintaining specified concrete performance
Concrete is the second most consumed material on the planet after water, but traditional cement production contributes to around 7% of global CO₂ emissions. At Sika, we’re driving change with innovative solutions that lower the carbon footprint of concrete—without compromising performance.
CARBON FOOTPRINT FOR TYPICAL CONCRETE VS SUSTAINABILITY POTENTIAL WITH SIKA ADMIXTURES
How We Reduce CO₂ in Concrete and Maintain Performance
The key to sustainable concrete is reducing the use of CEM I, the primary source of emissions in conventional mixes. By leveraging advanced low-carbon admixtures, you can replace CEM I with high levels of Supplementary Cementitious Materials (SCMs) such as GGBS or PFA—while maintaining strength, durability, and workability.
Sika’s cutting-edge technology makes this transition seamless, enabling the construction industry to build smarter and greener.
