ADEME, the French government agency for ecological transition, published an opinion on October 7, 2026, comparing the lifetime costs and environmental impact of electric and gasoline-powered cars in France. The opinion concludes that households moving from an old diesel vehicle to a new electric one spend roughly three times less money on running the car, driven mainly by cheaper charging, lower maintenance bills and a shrinking purchase-price gap.
Running Costs: Charging and Maintenance
According to ADEME, recharging an electric car costs "three times less, or more" than filling a gasoline or diesel tank for the same distance. Routine maintenance on an electric car is about 40% cheaper than on a comparable gasoline model, the agency said, because electric drivetrains have fewer moving parts that require servicing.
- Charging cost: roughly three times cheaper than a gasoline or diesel fill-up, per ADEME
- Routine maintenance: about 40% cheaper for electric cars than for gasoline equivalents
- Purchase-price gap: about €5,200 in 2025, down from €10,000 in 2024
The Purchase-Price Gap Is Shrinking
The extra cost of buying a new electric car instead of an equivalent gasoline model — for comparable models such as the Peugeot 208, Citroën C3 and Renault 5 — fell to around €5,200 in 2025, down from about €10,000 in 2024, ADEME found.
Electric cars accounted for two of every five new cars sold in France in September 2026, even though 93% of the country's existing vehicle fleet still runs on fossil fuel, according to the agency's figures reported by Franceinfo.
Carbon Footprint Over a Car's Lifetime
Franceinfo, Caradisiac and Generation-NT all reported that ADEME puts an electric car's lifecycle carbon footprint at roughly half that of a comparable gasoline or hybrid model, an advantage the agency attributes to France's low-carbon electricity grid. A manufacturing-emissions "payback" point is reached after about 70,000 kilometers of driving, after which the electric car's cumulative carbon footprint falls below the gasoline car's, according to all three outlets' accounts of the opinion. By 240,000 kilometers, Caradisiac reported, ADEME president Sylvain Waserman said the gap widens to 2.25 times less carbon-intensive for a compact electric car with a 60 kWh battery, saying: "The electric vehicle wins the match; it is 2.25 times less impactful in carbon terms."
Electric cars still generate particulate pollution despite having no exhaust pipe, because their added weight increases tire and road wear. ADEME's figures, as reported by Caradisiac, show electric cars emitting about 50% less PM10 and roughly one-third less PM2.5 than conventional cars overall.
The Trade-offs: Minerals and Recycling
Electric cars require about six times more critical metals and minerals than gasoline cars, mainly for their batteries, according to Caradisiac's reporting of the ADEME opinion. Battery production alone accounts for roughly half of an electric car's total manufacturing carbon footprint, though relocating battery manufacturing to regions with low-carbon electricity can cut that footprint by 15% to 25%, Caradisiac reported.
Recycling remains a limiting factor: current industrial processes cannot yet efficiently recover materials such as cobalt, nickel and lithium at scale, a concern as the first large wave of electric cars approaches end-of-life in an estimated 10 to 15 years, according to Caradisiac's summary of the study.

Why This Comes Up Now
Transport accounts for about one-third of France's national greenhouse gas emissions, and private cars generate 53% of the transport sector's CO2, according to figures cited by Franceinfo, which is part of the context ADEME gives for publishing the comparison.
Questions
- Are electric cars really three times cheaper than gasoline cars?
- ADEME's figure refers to running costs specifically: a household moving from an old diesel car to a new electric one spends about three times less on charging and maintenance combined, not necessarily three times less in total ownership cost once the purchase price is included.
- How much more expensive is it to buy an electric car than a gasoline one?
- The average price premium for a new electric car over an equivalent gasoline model was about €5,200 in 2025, down sharply from about €10,000 in 2024, according to ADEME.
- Do electric cars produce zero pollution?
- No. While they have no tailpipe emissions, their extra weight causes more tire and road wear, so ADEME's figures still show measurable particulate emissions — about 50% less PM10 and roughly a third less PM2.5 than gasoline cars, per Caradisiac's reporting.
- Are electric car batteries worse for the environment to produce?
- Battery production requires about six times more critical metals and minerals than a gasoline car needs, and current recycling technology cannot yet efficiently recover materials like cobalt, nickel and lithium at industrial scale, according to ADEME's findings as reported by Caradisiac.
- When does an electric car's carbon footprint become lower than a gasoline car's?
- ADEME's opinion, as reported by Caradisiac, says the manufacturing-emissions gap is offset after about 70,000 kilometers of driving, after which the electric car's cumulative footprint stays lower for the rest of its life.
