This kwh to co2 reference table shows the co₂ emissions for a range of electricity used values, assuming an emission factor (kg co₂/kwh) of 0.82. Every figure is computed with the same engine that powers our kWh to CO2 Calculator, so the numbers are exact.
| Electricity used | CO₂ emissions | Trees to offset (per year) |
|---|---|---|
| 130 kWh | 106.6 | 5.1 |
| 250 kWh | 205.0 | 9.8 |
| 380 kWh | 311.6 | 14.8 |
| 500 kWh | 410.0 | 19.5 |
| 750 kWh | 615.0 | 29.3 |
| 1,000 kWh | 820.0 | 39.0 |
| 1,500 kWh | 1,230.0 | 58.6 |
| 2,500 kWh | 2,050.0 | 97.6 |
| 3,500 kWh | 2,870.0 | 136.7 |
| 5,000 kWh | 4,100.0 | 195.2 |
How to use this table
Find the row closest to your electricity used and read across to the co₂ emissions. For a value between two rows, the real figure sits between them — or enter your exact numbers in the kWh to CO2 Calculator for a precise answer.
Need a value that is not in the table? — the kWh to CO2 Calculator does it instantly, for free, with the formula and a worked example built in.
