Embodied carbon: Cotton insulation has a relatively low embodied carbon compared to synthetic materials. The embodied carbon for cotton insulation typically ranges from 0.3 to 1.0 kg CO₂e per square meter per inch of thickness. As a plant-based material, cotton stores carbon during its growth, helping offset the emissions from its production.
