Insulation can be net CO₂-negative. The baseline measurement by New Economy for Wesselink shows the CO₂ saving is almost twice the production impact, using 100% biobased material. Net-negative insulation turns a building material into a carbon store. 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: New Economy (2021).
