Calculadora de Emisiones de Envío — Fórmula
## How to Calculate Shipping Emissions
Shipping emissions depend on weight, distance, and transport mode.
### Mode Factors (lbs CO2 per ton-mile)
- **Truck**: ~0.37
- **Rail**: ~0.05
- **Ocean Ship**: ~0.01
- **Air freight**: ~2.2
### Formula
**CO2 = (Weight / 2000) * Distance * Mode Factor**

Ejemplo Resuelto
Ship a 10-lb package 1,000 miles by truck.
- Weight in tons: 10 / 2000 = 0.005 tons
- CO2: 0.005 * 1000 * 0.37 = 1.85 lbs
- In kg: 1.85 / 2.205 = 0.84 kg CO2
