Estimate emissions across operations with detailed scope tracking. Review totals, intensity, costs, and offsets for smarter decisions.
Enter activity data and matching emission factors. Results appear above this form after submission.
Basic source formula: Emissions = Activity Data × Emission Factor
Refrigerants: Emissions (tCO2e) = Refrigerant Leakage (kg) × GWP ÷ 1000
Scope 1: Stationary + Mobile + Refrigerants + Process Emissions
Scope 2: Purchased Electricity × Electricity Factor
Scope 3: Waste + Business Travel + Employee Commuting
Gross Total: Scope 1 + Scope 2 + Scope 3
Net Total: Gross Total − Offsets
Intensity per Unit: Gross Total ÷ Production Units
Carbon Cost: Gross Total × Carbon Price
This setup lets users enter their own factors, so the calculator stays flexible across fuels, grids, travel modes, and reporting frameworks.
| Input Item | Example Value | Unit |
|---|---|---|
| Stationary Fuel Use | 12,000 | Liters |
| Stationary Fuel Factor | 0.00268 | tCO2e per liter |
| Mobile Fuel Use | 6,500 | Liters |
| Electricity Use | 185,000 | kWh |
| Refrigerant Leakage | 18 | kg |
| Waste Generated | 42 | Tonnes |
| Business Travel | 38,000 | km |
| Employee Commuting | 125,000 | km |
| Process Emissions | 22 | tCO2e |
| Offsets | 15 | tCO2e |
It estimates greenhouse gas emissions in tCO2e across direct, energy, and selected indirect categories. It also summarizes scope totals, offsets, intensity, and estimated carbon cost.
Different countries, fuels, suppliers, and reporting methods use different factors. Manual entry keeps the tool flexible and lets you apply organization-approved factors from your preferred inventory standard.
Use the same unit that matches your emission factor. For example, if your factor is tCO2e per liter, then fuel must be entered in liters. Consistent units are essential.
The calculator multiplies leaked refrigerant mass in kilograms by the refrigerant’s global warming potential, then divides by 1000 to convert the result into tonnes of carbon dioxide equivalent.
Scope 1 covers direct emissions, Scope 2 covers purchased electricity, and Scope 3 covers indirect value-chain sources like waste, business travel, and employee commuting.
No. Gross emissions remain the primary inventory value. Net total is useful for internal analysis after subtracting offsets, but many frameworks still require gross emissions to be reported clearly.
Carbon cost is an estimated financial exposure based on the carbon price you enter. It helps compare operational choices and visualize potential climate-related cost impacts.
Yes. You can enter monthly data instead of annual totals. Just keep all inputs and factors aligned to the same time period, then compare results consistently month by month.
