What makes hempcrete so sustainable?
Not only does hempcrete provide exceptional thermal performance, significantly reducing operational carbon emissions through the lifetime of the building, but in terms of embodied carbon it is actually a better-than-zero-carbon material. This means that more carbon is removed from the atmosphere and stored in the material than is emitted by its production and installation on-site.
The amount of carbon sequestered in a hempcrete wall varies depending on the exact type and source of materials, as well as on the application technique. Depending on the material type and source, estimates range from 60-165kg of CO2 sequestered per cubic metre of hempcrete.
