EV Charger ScoutCO₂ Savings
Measure your carbon footprint reduction worldwide
See your real-world annual CO₂ reduction compared to driving a gasoline car. Uses country-specific grid carbon intensity data so your results reflect where your electricity actually comes from.
Grid intensity: 386 gCO₂/kWh (🇺🇸 United States)
Your Annual Impact
CO₂ Saved Per Year
2.5t
2,502 kg of CO₂ avoided annually
Grid intensity from 2024–2026 national averages (Ember, Electricity Maps, EIA). Actual impact varies by your utility's energy mix and driving conditions.
How the CO₂ savings calculator works
Driving on electricity is only as clean as the grid that produced it. This calculator estimates the CO₂ you avoid each year by driving an EV instead of a comparable gas car, using the average carbon intensity of the electricity grid in your country. Countries with lots of hydro, nuclear or wind (France, Sweden, Norway, Canada) show the largest savings; coal-heavy grids show smaller but still positive savings.
Grid intensity figures come from public sources such as Ember, Electricity Maps and the US EIA, and are updated as those sources publish new annual data. Gas-car emissions use the standard figure of roughly 8.9 kg of CO₂ per US gallon of gasoline burned.
Frequently asked questions
Does an EV really save CO₂ on a coal-heavy grid?
Yes, in almost every country. Electric motors are 3–4 times more efficient than combustion engines, so even electricity from a mostly fossil grid produces less CO₂ per mile than burning gasoline.
Does this include battery manufacturing emissions?
No — this is a driving-phase comparison only. Battery production adds a one-time carbon cost that most studies find is repaid within one to two years of typical driving.
Can I use my own electricity mix?
Pick the country whose grid is closest to yours. If you charge from home solar, your real savings will be higher than any country average.
