How does concrete’s carbon footprint compare to natural stone?

Concrete and natural stone are two widely used materials in construction, but their environmental impacts differ significantly. Concrete production is a major source of CO2 emissions, accounting for nearly 8% of global emissions due to cement manufacturing. The process involves high-energy consumption and chemical reactions that release large amounts of carbon dioxide.

In contrast, natural stone has a much lower carbon footprint. Quarrying and processing stone require less energy, and no chemical processes are involved. Additionally, stone is a durable, long-lasting material that doesn’t require frequent replacement, further reducing its environmental impact over time.

However, transportation plays a key role. Locally sourced stone can be far more sustainable, while imported stone may have higher emissions due to shipping. Concrete, on the other hand, is often produced near construction sites, reducing transport-related emissions.

For eco-conscious projects, natural stone is generally the greener choice, but sustainable concrete alternatives, such as low-carbon mixes or recycled aggregates, are emerging as viable options. The best choice depends on project requirements, location, and long-term sustainability goals.
