Estimate annual building emissions from purchased electricity and on-site fuel. Enter consumption and matching emission factors to calculate total operational CO₂e, the contribution of each energy source, and intensity per floor area.
The main result estimates annual operational emissions from the two energy streams entered. It does not include refrigerants, water, waste, tenant activities outside the meters, or embodied carbon.
Use emission factors for the same reporting year and method. Market-based and location-based electricity results should not be mixed without clear documentation.
450,000 kWh of electricity at 0.38 kg/kWh plus 180,000 kWh of fuel at 0.184 kg/kWh equals 204.12 t CO₂e, or 17.01 kg CO₂e/m² across 12,000 m².
No. It covers operational electricity and on-site fuel only.
Use the method required by your inventory and label it clearly; do not combine methods in a single comparison without explanation.
Convert it to kWh or use a compatible energy unit and factor before entering it here.
Use the area definition applied consistently across the buildings or reporting periods being compared.
No. Add refrigerant and other emission sources separately for a more complete operational inventory.
