Carbon Sequestration

Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. Our focus is on natural carbon sequestration, which occurs when living organisms absorb carbon dioxide and store it as carbon in the ground or as biomass.

We design our buildings primarily with biomass materials such as timber, straw, hemp, and bamboo, combined with clay, lime, or biochar. These natural materials store carbon, significantly reducing the carbon footprint of the built environment.

To illustrate the impact, a typical Passivhaus family home built with energy-intensive petrochemical materials emits, on average, 50 tonnes of carbon during construction and 50 tonnes during operational use over its lifespan—a total of 100 tonnes.

In contrast, an equivalent building constructed using biomass materials stores 30 tonnes of carbon during construction and emits 50 tonnes in operational energy use, resulting in a net total of 15 tonnes. This equates to a 660% reduction in carbon emissions compared to conventional materials.
