Calculadora de Emisiones de Manufactura — Fórmula
## How to Calculate Manufacturing Emissions
Manufacturing emissions come from energy use and material processing.
### Components
1. **Electricity**: kWh * 0.92 lbs CO2/kWh
2. **Natural Gas**: MMBtu * 117 lbs CO2/MMBtu
3. **Process emissions**: Vary by material (steel ~1.8, aluminum ~8.0, cement ~0.9 tons CO2/ton)
### Formula
**Total = Energy CO2 + Process CO2**

Ejemplo Resuelto
A factory using 50,000 kWh/month, 200 MMBtu/month gas, processing 100 tons/month at 0.5 tons CO2/ton.
- Electricity CO2: 50,000 * 12 * 0.92 / 2,204.6 = 250 metric tons
- Gas CO2: 200 * 12 * 117 / 2,204.6 = 127 metric tons
- Material CO2: 100 * 12 * 0.5 = 600 metric tons
- Total: 250 + 127 + 600 = 977 metric tons/year
