While buildings and their operations account for 40% of all carbon emissions globally, biogenic construction materials made from plants like hemp and straw have the potential to turn our built environment from a carbon emitter to a carbon sink.

Graft’s modular system of biogenic pods allows for the grafting of these carbon-sequestering materials onto existing buildings, improving energy performance and material health, locking away carbon, and introducing new functionality into old structures rather than demolishing them.

The AI-powered surveying system and marketplace expedites the construction, permitting, and subsidy process for homeowners and developers, and the pods’ regenerative local material ecology empowers farmers.
