2. 2 Capture green building materials and convert it into Calera’s Solution CO 2

3. 3 Power Calera Clean Air (reduced or zero CO 2 ) Flue gas Cooling seawater (or alternative direct source) Cooling seawater Green Cement Demineralized Water (stripped of Ca & Mg) Calera Process

4. 4 Calera Process as Biomimicry + = Coral Coral process Seawater absorbs CO2 CO2 minerals Calera’s process is similar to coral reef formation

5. 5 Carbon Capturing Materials “Being less bad is not good enough” Normal Concrete Carbon Capturing Concrete Carbon Footprint + - With 50% Fly Ash

6. 6 Calera’s Pilot Facility >3.4 million tons CO2 per year Source: EPA (2007) CO2 Source: Largest Power Provider in California Moss Landing, CA >1000 MW base load >1500 MW peaking Natural Gas
