Carbon Footprint Calculator
Calculate comprehensive carbon emissions across all scopes


MWh


km


tonnes

📊 Calculation Formula

Total Carbon = (Energy × 0.5) + (Transport × 0.0002) + (Waste × 0.3)
💡 Example Calculation:
Energy: 100 MWh
Transport: 5,000 km
Waste: 10 tonnes
Calculation:
(100 × 0.5) + (5,000 × 0.0002) + (10 × 0.3)
= 50 + 1 + 3
= 54 tCO2e
⚡ Quick Reference – Emission Factors:
Source Factor Unit
Electricity 0.5 tCO2e per MWh
Transportation 0.0002 tCO2e per km
Waste 0.3 tCO2e per tonne

Water Usage Assessment
Analyze water consumption efficiency and intensity


m³


people


$M

📊 Calculation Formulas

Water per Employee = Water Consumption ÷ Number of Employees
Water Intensity = Water Consumption ÷ Revenue (m³/$M)
💡 Example Calculation:
Water: 1,000 m³
Employees: 50
Revenue: $10M
Per Employee: 1,000 ÷ 50 = 20 m³/employee
Intensity: 1,000 ÷ 10 = 100 m³/$M

Waste Management Tracker
Track waste generation and recycling performance


tonnes


tonnes


tonnes

📊 Calculation Formulas

Recycling Rate = (Recycled Waste ÷ Total Waste) × 100
Hazardous Waste % = (Hazardous Waste ÷ Total Waste) × 100
💡 Example Calculation:
Total Waste: 100 tonnes
Recycled: 75 tonnes
Hazardous: 5 tonnes
Recycling Rate: (75 ÷ 100) × 100 = 75%
Hazardous %: (5 ÷ 100) × 100 = 5%

⚡
Energy Efficiency Calculator
Measure renewable energy adoption and efficiency


MWh


MWh


units

📊 Calculation Formulas

Renewable % = (Renewable Energy ÷ Total Energy) × 100
Energy Intensity = Total Energy ÷ Production Output
💡 Example Calculation:
Total Energy: 200 MWh
Renewable: 150 MWh
Output: 1,000 units
Renewable %: (150 ÷ 200) × 100 = 75%
Intensity: 200 ÷ 1,000 = 0.2 MWh/unit
