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

When choosing materials for outdoor sofas, the carbon footprint is a critical factor for eco-conscious consumers. Concrete, while durable, has a significantly higher carbon footprint due to its energy-intensive production process, which involves cement manufacturing—a major source of CO2 emissions. Natural stone, on the other hand, requires minimal processing and has a lower carbon footprint, as it is quarried and cut with less energy. However, transportation impacts vary depending on the stone's origin. For sustainability, locally sourced natural stone is often the better choice, while concrete alternatives like recycled or low-carbon mixes can mitigate its environmental impact. Consider durability, maintenance, and lifecycle emissions when deciding between these materials for your outdoor furniture.
