The baseline measurement for Wesselink Isolatie shows that each kilogram of biobased insulation stores 1.21 kg CO₂ net. The calculation combines 1.3 kg of stored CO₂ with 0.09 kg of emissions from production and installation. Using the net figure prevents storage from being presented without the material impact.
The result applies to the assessed Wesselink situation and should not automatically be generalised to every insulation material. A full baseline measurement compares production, installation and the use phase and shows where further reductions are possible. Source: Wesselink insulation climate impact, New Economy.
