Stored CO₂ per kilogram of insulation being more than 14 times production and installation emissions shows why biobased insulation can be materially different from conventional products. The carbon stored in the material can outweigh the emissions needed to produce and install it.
In the Wesselink baseline work, this turns insulation into both an energy and carbon question. The climate value depends on material origin, lifetime, installation, end-of-life treatment and whether the stored carbon remains locked in for a meaningful period. That makes product-level data essential.
