Every kilogram of biobased insulation stores 1.3 kg CO₂, against 0.09 kg emitted in production. This core figure from the baseline measurement by New Economy for Wesselink (2021) shows storage far outweighs production emissions. The production impact of insulation material is often overlooked, leaving the net climate gain unknown.
A baseline measurement makes production, installation and use phase measurable and shows whether insulation is net CO₂-negative. This is relevant for insulation companies, construction firms and clients in the built environment. Source: Nulmeting Wesselink (2021).
