Proof Engine Verification: Electric vehicles have a larger lifetime carbon footprint than gasoline cars when manufacturing and battery disposal are included.

Automated fact-verification of the claim: "Electric vehicles have a larger lifetime carbon footprint than gasoline cars when manufacturing and battery disposal are included." Verdict: DISPROVED (with unverified citations) Key Findings Every major lifecycle analysis reviewed concludes EVs have significantly lower lifetime emissions than gasoline cars, even when including manufacturing and battery disposal — the opposite of what the claim asserts. EVs produce 60-69% lower lifetime greenhouse gas emissions than gasoline cars in the United States, and 66-69% lower in Europe (ICCT global lifecycle analysis). While EV manufacturing creates 40-80% more emissions than gasoline car manufacturing (due to battery production), this "emissions debt" is recovered within 1.5-2 years of typical driving. A gasoline car produces approximately 76 metric tonnes CO2 over its lifetime vs 37 metric tonnes for an EV — roughly half (B3).
