The environmental impact of mycelium insulation is assessed with the Environmental Cost Indicator because the material has to be compared across multiple impact categories, not only on climate. The ECI translates environmental effects into a single score that supports comparison with other insulation options.
In the Fairm mycelium baseline, this helps identify the relevant hotspots in production, materials and logistics. The method makes it possible to improve the product design while keeping the assessment practical for buyers, designers and circular-construction partners.
