U‑M Study Finds EVs Beat Gas and Hybrids on Lifetime Emissions in Every U.S. County

The study delivers county‑level results across 35 vehicle–powertrain combinations, plus a calculator for location‑specific estimates.

Overview

  • Researchers published the peer‑reviewed analysis in Environmental Science & Technology using Argonne’s life‑cycle model and EPA model‑year‑2025 vehicle data.
  • An ICE pickup averages 486 g CO2e per mile, while a compact 200‑mile‑range BEV averages 81 g CO2e per mile, roughly 17% of the gas pickup’s footprint.
  • Electrifying pickups yields the largest absolute reductions, with a fully electric pickup cutting emissions about 75% versus a gas pickup and staying under 30% even when hauling 2,500 pounds.
  • Non‑plug‑in hybrids trim life‑cycle emissions by about 11–13%, whereas 35–50 mile PHEVs cut 53–60% assuming 58–69% electric‑mode driving, and smaller‑battery BEVs post the lowest totals.
  • Grid carbon intensity and temperature shift results by location and use, yet BEVs remain lower everywhere, and a free online calculator lets users tailor estimates by vehicle, driving pattern and county.
