The Hidden Cost: Carbon Footprint Analysis of Construction Materials

This study evaluates the carbon footprint of construction materials using a lifecycle approach and finds that materials such as concrete, steel, and aluminum are major contributors to emissions. Concrete is the most significant due to cement production. The results show that manufacturing and extraction stages generate the highest emissions, highlighting the need for cleaner technologies and alternative materials. Timber and bio-based materials offer sustainable options, while innovative materials like hempcrete and biochar composites present future opportunities. A key conclusion is that material selection alone can reduce emissions by more than 70%, emphasizing the importance of sustainable design decisions. Achieving low-carbon construction requires collaboration among researchers, industry professionals, and policymakers. Standardization, recycling, and technological innovation are essential steps. Reducing the carbon footprint of construction materials is crucial for sustainability and combating climate change.
