The construction industry significantly contributes to global carbon emissions, with cement and concrete production accounting for nearly 7% of total CO2 emissions. Their environmental impact stems from energy-intensive manufacturing processes and CO2-releasing chemical reactions. This paper explores sustainable alternatives to traditional cement and concrete to mitigate their carbon footprint.
Alternative materials such as fly ash, slag, and limestone can replace portions of traditional cement, reducing CO2 emissions by up to 40% while maintaining strength and durability. Additionally, carbon capture and storage (CCS) technologies have shown potential in reducing emissions from cement plants by up to 60%. Enhancing the natural carbonation process in concrete can further increase its ability to sequester CO2 over time, transforming it into a more effective carbon sink.
Case studies highlight the success of these approaches in real-world applications. However, challenges such as high costs and the need for regulatory support persist. The paper underscores the necessity for continued research, industry collaboration, and policy development to accelerate the adoption of low-carbon construction materials. These efforts are crucial for reducing the construction sector's environmental impact and supporting global climate change mitigation initiatives.
