• Modular construction with wood

Example narrative for ID point: "Project uses hybrid concrete and CLT system, reducing 60% of carbon footprint vs conventional structure, with 100% FSC certified wood from Mexican forests, demonstrating technical and economic viability of mass timber in Mexico."

Carbon Capture Strategy

Stored Carbon Calculation

Wood captures CO₂ during growth:

• 1 m³ of wood = 0.9 tons CO₂ captured
• Remains stored during building lifespan

Example: 1,000 m² building with CLT structure:

• Wood volume: 120 m³
• CO₂ captured: 108 tons
• Equivalent to: Removing 23 cars from circulation for 1 year

Comparison with concrete:

• Concrete structure: +120 ton CO₂ emitted
• Wood structure: -108 ton CO₂ captured
• Difference: 228 tons CO₂

Life Cycle Carbon Footprint

Complete analysis (cradle to grave):

Concrete Structure:

• Material extraction: +40 kg CO₂/m²
• Manufacturing: +85 kg CO₂/m²
• Transportation: +12 kg CO₂/m²
• Construction: +8 kg CO₂/m²
• Total: +145 kg CO₂/m²

Wood Structure:

• Forestry: -120 kg CO₂/m² (capture)
• Processing: +25 kg CO₂/m²
• Transportation: +10 kg CO₂/m²
• Construction: +5 kg CO₂/m²
• Total: -80 kg CO₂/m²

Net benefit: 225 kg CO₂/m² in favor of wood
