## 1. CO₂ Emissions Reduction

### 1.1 Methodology

Turash uses **GHG Protocol-compliant calculations** for CO₂ emissions avoidance from industrial symbiosis exchanges. The platform tracks:

1. **Waste Heat Recovery** - Displacing fossil fuel-based heating/cooling
2. **Material Reuse** - Avoiding virgin material production
3. **Water Recycling** - Reducing energy-intensive water treatment
4. **Waste Diversion** - Avoiding landfill methane emissions

### 1.2 CO₂ Calculation Methods

#### Heat Recovery (Primary Impact - Year 1 Focus)

**Formula**: 
```
CO₂ Avoided (t) = Heat Energy Recovered (MWh) × Grid Emission Factor (t CO₂/MWh) × Conversion Efficiency Factor
```

**Parameters**:
- **Grid Emission Factor**: 0.3 t CO₂/MWh (EU average, 2025)
- **Conversion Efficiency Factor**: 0.9 (accounting for heat exchanger losses)
- **Source**: European Environment Agency (EEA) grid mix data

**Calculation Example**:
- **500 GWh waste heat recovered** (Year 1 target)
- **CO₂ Avoided**: 500 GWh × 0.3 t CO₂/MWh × 0.9 = **135,000 t CO₂** (Year 1)

**Conservative Estimate** (accounting for variable demand):
- **100,000 t CO₂** avoided (Year 1, realistic with 70% utilization rate)

#### Material Reuse & Waste Diversion

**Formula**:
```
CO₂ Avoided (t) = Waste Diverted (t) × Production Emission Factor (t CO₂/t) × Waste-to-Energy Credit (t CO₂/t)
```

**Parameters**:
- **Production Emission Factor**: Varies by material (steel: 2.0, concrete: 0.3, plastics: 2.5 t CO₂/t)
- **Waste-to-Energy Credit**: 0.2 t CO₂/t (avoided landfill methane)
- **Average Material Impact**: 1.5 t CO₂/t (blended across materials)

**Year 1 Example**:
- **50,000 t waste diverted**
- **CO₂ Avoided**: 50,000 t × 1.5 t CO₂/t = **75,000 t CO₂**

#### Water Reuse

**Formula**:
```
CO₂ Avoided (t) = Water Reused (m³) × Treatment Energy (kWh/m³) × Grid Emission Factor (t CO₂/MWh) / 1000
```

**Parameters**:
- **Treatment Energy**: 0.5-1.5 kWh/m³ (typical industrial water treatment)
- **Average**: 1.0 kWh/m³
- **Grid Emission Factor**: 0.3 t CO₂/MWh

**Year 1 Example**:
- **2.5 M m³ water reused**
- **CO₂ Avoided**: 2.5 M m³ × 1.0 kWh/m³ × 0.3 t CO₂/MWh / 1000 = **750 t CO₂**
