Are electric vehicles really better for the environment? The answer depends on how you drive, where you charge, and how long you own the car. Our EV Emissions Calculator provides a comprehensive comparison between electric vehicles and traditional gasoline cars, accounting for manufacturing emissions, electricity grid mix, driving patterns, and lifetime ownership. Discover your break-even point and see exactly how much CO₂ you can save by going electric.
Electric vehicle emissions aren't zero—they include manufacturing (especially the battery), electricity generation for charging, and end-of-life processing. However, EVs typically have much lower lifetime emissions than gasoline cars. The key factors are: 1) Battery production adds 6-12 tonnes CO₂ upfront, 2) Driving emissions depend entirely on your electricity grid, 3) EVs have no tailpipe emissions. On the US average grid, EVs emit about 60% less CO₂ over their lifetime than comparable gasoline vehicles.
EV Emissions Formula
EV CO₂/year = (Annual Miles ÷ mi/kWh) × Grid CO₂/kWhSee exactly how your driving habits and local grid affect the environmental case for an EV purchase.
Electricity source matters enormously—EVs in coal-heavy regions have higher emissions than those on renewable grids.
Calculate when your EV's lower operating emissions offset its higher manufacturing footprint.
As grids get cleaner, your EV's emissions automatically decrease—unlike gasoline cars.

In most cases, yes. Despite higher manufacturing emissions (primarily from battery production), EVs produce significantly lower lifetime emissions than gasoline cars. On the US average grid, an EV emits about 60% less CO₂ over its lifetime. In regions with clean electricity (renewable, nuclear, hydro), the advantage is even greater—up to 90% lower emissions. Even in coal-heavy regions, EVs typically come out ahead over a 10+ year ownership period.
