In the next decades, a large share of residential buildings in EU-28 is expected to be renovated and a large amount of insulation materials will be produced.Bio-based materials are a valuable alternative to insulate the Hydro 4 Parts buildings and the biogenic carbon can be stored in the built environment for a relative long time.This article investigates the effect of massively storing carbon in construction when different bio-based materials are used.The results show that Deodorant only bio-based material with a very fast regrowth, e.g.
straw, have an effective potential in removing carbon from the air in a very short-time, and can contribute to achieve the Paris Agreement goals by 2050.
