🌍 GCC Emissions Calculator

Professional greenhouse gas emissions calculator designed specifically for organizations in the UAE and Saudi Arabia. Calculate your carbon footprint across Scope 1, 2, and 3 emissions with region-specific emission factors.

✨ Key Features

🎯 Region-Specific Design

• UAE Grid Factors: Emirate-specific factors (DEWA, ADWEA, SEWA, FEWA)
• Saudi Grid Factors: Region-specific factors including NEOM renewable city
• GCC Coverage: Includes Kuwait, Qatar, Bahrain, and Oman
• Climate Adapted: Accounts for cooling needs and desalination

📊 Comprehensive Calculations

• Scope 1: Direct emissions from fuel combustion
• Scope 2: Indirect emissions from purchased electricity
• Scope 3: Value chain emissions including:
  • Business travel & employee commuting
  • Water consumption (desalination)
  • Waste disposal
  • Cooling systems

🛠️ Technical Features

• Standards Compliant: GHG Protocol & ISO 14064
• RESTful API: Easy integration with existing systems
• Offline Capable: Works without internet connection
• Mobile Responsive: Calculate on any device
• Data Privacy: All calculations performed locally

💻 Usage Examples

Basic Calculation (Python)

from src.calculator import GHGCalculator

# Initialize calculator
calc = GHGCalculator()

# Calculate Scope 1 emissions
result = calc.calculate_scope1(
    fuel_type="natural_gas",
    amount=10000,
    unit="m3"
)
print(f"Emissions: {result.total} tCO2e")

# Calculate Scope 2 emissions
result = calc.calculate_scope2(
    electricity_kwh=50000,
    location="Dubai",
    method="market_based",
    renewable_percentage=10
)
print(f"Emissions: {result.total} tCO2e")

API Usage

# Calculate Scope 1 emissions
curl -X POST http://localhost:8000/api/calculate/scope1 \
  -H "Content-Type: application/json" \
  -d '{
    "fuel_type": "diesel",
    "amount": 1000,
    "unit": "L"
  }'

# Get emission factors
curl http://localhost:8000/api/factors

Comprehensive Facility Assessment

# Annual facility assessment
facility_data = {
    "name": "Dubai Manufacturing Plant",
    "fuels": [
        {"type": "natural_gas", "annual_amount": 50000, "unit": "m3"},
        {"type": "diesel", "annual_amount": 10000, "unit": "L"}
    ],
    "electricity": {
        "annual_kwh": 1000000,
        "location": "Dubai",
        "method": "market_based",
        "renewable_percentage": 15
    },
    "transport": [
        {"mode": "car_medium", "annual_distance": 50000},
        {"mode": "airplane_gcc", "annual_distance": 20000}
    ],
    "water": {
        "annual_m3": 5000,
        "type": "desalinated_water_uae"
    }
}

results = calculate_annual_emissions(calc, facility_data)
print(f"Total Annual Emissions: {results['total']} tCO2e")
