How does the carbon footprint of concrete bench production compare to natural stone?

The carbon footprint of concrete bench production is significantly higher than that of natural stone. Concrete manufacturing involves energy-intensive processes like cement production, which alone accounts for about 8% of global CO2 emissions. The extraction, transportation, and curing of concrete materials further contribute to its environmental impact.

In contrast, natural stone requires minimal processing, often needing only cutting and polishing. While quarrying stone does emit CO2, the overall footprint is lower due to the absence of high-temperature kilns and chemical reactions involved in cement production. Additionally, natural stone is more durable and requires less maintenance, reducing its long-term environmental impact.

For eco-conscious projects, reclaimed or locally sourced stone can further minimize emissions, while concrete alternatives like geopolymer or recycled-aggregate mixes offer greener options. Choosing between these materials depends on balancing aesthetics, durability, and sustainability goals.
