Read full description
The company's business model is centered around the production and sale of these eco-friendly concrete blocks. They serve a variety of clients, including concrete producers, the building industry, and carbon credit buyers. Concrete producers can benefit from the company's industry-leading Environmental Product Declarations (EPDs), which can help them win bids. The building industry can achieve deep embodied carbon reductions, measurable ESG impacts (Environmental, Social, and Governance), and excellent LEED scores (Leadership in Energy and Environmental Design), a popular green building certification. Carbon credit buyers can access high-quality carbon credits that avoid and permanently remove CO2, accelerating the decarbonization of concrete.
CarbonBuilt's revenue is generated from the sale of their ultra-low carbon concrete blocks and carbon credits. The company's unique selling point is that their blocks do not cost more to produce than traditional concrete blocks, making them a cost-effective solution for their clients.
