Driving an EV for 1 km
Sähköautolla ajaminen 1 km
Carbon well-established. Water and toxicity around mining have significant uncertainty.
One EV kilometer produces ~53g CO₂e (EU grid + battery manufacturing), with 30% more tire microplastics than gasoline cars due to heavier batteries.
How was this number determined?
The Truecost score is calculated from absolute physical values. Each row below shows the measured value, how it was normalized, and where it comes from.
| Dimension | Absolute value | Score 100 = | Normalized | Weight | Weighted | Confidence |
|---|---|---|---|---|---|---|
| Carbon Emissions | 0.053 kg CO₂e | 9.5 kg CO₂e | 0.56 | ×0.35 | 0.20 | HIGH |
| Water Consumption | 3.0 liters | 3840 liters | 0.08 | ×0.2 | 0.02 | MEDIUM |
| Land Use | 0.1 m²·year | 51 m²·year | 0.2 | ×0.2 | 0.04 | LOW |
| Waste | 0.0003 kg | 5 kg | 0.01 | ×0.15 | 0.00 | HIGH |
| Toxicity | 0.5 µDALY | 162 µDALY | 0.31 | ×0.1 | 0.03 | LOW |

EVs produce MORE tire microplastics than ICE. Almost never discussed.

Comparisons
- Carbon: 3x less than a gasoline car per km
- But 30% more tire microplastics due to weight
Methodology
T&E (2023) lifecycle analysis. 0.18 kWh/km, EU grid 250g/kWh. Battery amortized over 200,000km. Tire wear +30% vs ICE.
