Cost
€280
CO₂
250.00 kg
0.250 tonnes
Formula with your numbers
cost = 1,000.000 × 0.28 = €280
CO₂_kg = 1,000.000 × 250 / 1000 = 250.000 kg
Frequently asked questions
Why is grid carbon intensity editable?+
Grams of CO₂ per kWh vary by country, season and even hour of day as the generation mix changes. The 250 g/kWh default is only a placeholder mid-range figure — replace it with a local published intensity.
