Measure electricity emissions with flexible units, factors, and scenarios. See market and location results instantly. Export clear reports for audits, disclosures, and planning teams.
The calculator uses a stacked page layout. The input grid changes to three columns on large screens, two on medium screens, and one on mobile.
| Example item | Sample value | Unit | Use in calculation |
|---|---|---|---|
| Electricity consumption | 125,000 | kWh | Total purchased electricity for the reporting period. |
| Grid emission factor | 0.42 | kg CO2e/kWh | Used for location-based emissions. |
| Market emission factor | 0.08 | kg CO2e/kWh | Used for non-renewable matched electricity. |
| Renewable matched share | 20 | % | Reduces market-based conventional electricity portion. |
| Transmission loss | 6 | % | Expands electricity when upstream losses are included. |
| Carbon price | 55 | per tonne CO2e | Estimates carbon cost exposure. |
1. Energy conversion:
Adjust all electricity to kWh before calculating emissions.
2. Adjusted electricity:
Adjusted kWh = Purchased kWh ÷ (1 − Loss %)
3. Renewable matched electricity:
Renewable kWh = Adjusted kWh × Renewable share
4. Location-based emissions:
Location emissions = Adjusted kWh × Grid factor
5. Market-based emissions:
Market emissions = (Adjusted kWh − Renewable kWh) × Market factor
6. Avoided market emissions:
Avoided emissions = Renewable kWh × Market factor
7. Carbon cost exposure:
Carbon cost = Market emissions in tonnes × Carbon price
8. Intensity metrics:
Intensity = Market emissions ÷ kWh, area, or activity output
9. Benchmark variance:
Variance = Market emissions − Benchmark emissions
Location-based reporting uses the average grid emission factor for the consumed electricity. It reflects the emissions intensity of the electricity system where consumption happened, regardless of contractual renewable purchases.
Market-based reporting uses supplier-specific or contractual factors. It can show lower emissions when renewable electricity purchases, energy certificates, or green tariffs reduce the emissions assigned to consumed electricity.
Including losses estimates the extra generation needed upstream to deliver your measured electricity. This gives a fuller view of electricity-related impact when your reporting framework requires upstream energy adjustments.
Yes. Enter the reporting period in months, such as 1 for monthly or 3 for quarterly data. The calculator will annualize market-based emissions using that period length.
Use the unit supplied by your utility, regulator, or ESG source. The calculator accepts kg, g, lb per kWh, and tonnes per MWh, then converts everything into consistent values.
Carbon cost exposure is calculated by multiplying market-based emissions in tonnes by the carbon price you enter. It is a planning estimate, not a guaranteed compliance cost.
Area and activity inputs help you calculate normalized emissions intensity. These ratios make performance easier to compare across buildings, sites, business units, or reporting periods.
Benchmark variance compares your market-based emissions with emissions produced by a target factor. A positive number means you are above the benchmark. A negative number means performance is better than target.
