It’s hard to overestimate the cumulative impact of adopting these new (very old) biogenic building materials (like hempcrete). The construction sector is the 3rd largest emitter of CO2 globally. Construction debris fills an estimated 45% of US landfills. Through the adoption of plant-based, high-performing materials, we can make our buildings carbon banks — solving our affordable housing crisis while also meeting our emission reduction goals to avoid the worst of climate change.
